The article presents archaeological investigations in the Sacharewo region in the Białowieża Forest in eastern Poland. Finds from the Iron Age and the Roman period suggest a possible revival of settlement between the 1st century BC and the 5th/6th century AD. The study includes geoarchaeological analyses, archaeobotanical investigations, and radiocarbon dating, which identify a stable settlement region. The finds show cultural influences during the Roman period, including the Hatched Pottery Culture and the Wielbark Culture. [Extracted from the article]

ABSTRACT Cultivation pits represented the principal form of horticultural features developed by past atoll communities in Central‐East Polynesia (CEP), and they are still utilised on some atolls in Oceania. The majority of information about the use of cultivation pits in CEP derives from ethnographic and preliminary archaeological investigations. The lack of excavations with rigorous stratigraphic sampling and analyses has constrained the recovery of environmental information associated with these agro‐technical features. Using a combination of geoarchaeological techniques, including field observations, physico‐chemical analyses and soil micromorphology, this study focuses on sedimentary deposits from a cultivation pit (MAITE‐01) on Teti'aroa atoll, in the Society Islands. We demonstrate how micro‐geoarchaeological investigations can advance research and offer new interpretations to study past human interactions within environments long considered “lost causes” to detailed archaeostratigraphic interpretation. High‐resolution geoarchaeological techniques reveal details about pit construction and provide indirect evidence of the integration of human‐animal interaction into the horticultural system.

The 1870s case of the archaeological forgeries attributed to Jerusalem antiquities dealer Moses Wilhelm Shapira continues to provoke interest. This article examines the association of the Moabitica, marketed by Shapira, to their Moabite origin using the modern scientific methods of ceramic petrography and X-ray fluorescence. The results serve, in turn, to illuminate an unanswered question raised by the historical account of the German explorers’ provisional delegation to Moab. The delegation traced the sources of the Moabitica antiquities in an attempt to locate additional Moabitica in situ where they had allegedly been found. The historical account is unclear as to whether this research trip was also part of the conspiracy organised by the Jerusalem counterfeiters or whether it solely involved a workshop and a team acting east of the Dead Sea. Combining the historical narrative and the geoarchaeological analysis, the affair is examined from a perspective never before undertaken. [ABSTRACT FROM AUTHOR]

The La Prele site (ca. 12,940 cal BP) is a deeply buried, single-component mammoth kill and campsite in Wyoming (USA). The site was discovered eroding from a creek bank 3 m deep within a 7-m tall terrace scarp, and prior investigations have primarily focused on excavations accessible from the creek bank, using heavy machinery to remove sterile overburden to access the deeply buried deposits. This approach has allowed excavations to occur safely outside of deep pits, but it has limited our ability to assess the total size and density of the site. To determine total site extent, we conducted systematic bucket auger testing of the La Prele site terrace, attempting 189 augers between 1.6 m and 6.2 m deep across the landform. We use a simulation and other mathematical procedures to infer artifact density from auger artifact counts and interpolate artifact densities across the site using GIS. We determine that La Prele is around 4500 m2 in area and likely contains a buried bison bonebed and two additional artifact concentrations comparable to or exceeding the size and density of previously excavated areas. We use these insights to infer Early Paleoindian group size, concluding that around 30 people occupied La Prele. [ABSTRACT FROM AUTHOR]

The open-air Epipalaeolithic (Geometric Kebaran) site of Neve David (Mount Carmel, Israel) has played an important role in reconstructing scenarios of sedentarization in the Levant since its initial excavation in the 1980s, and has been seen as heralding later Natufian socioeconomic adaptations. However, little was known about the site's formation processes and spatial organization, hindering the testing of this view. Employing new field data from Neve David, we present a combined macro- and microscopic analyses of the spatial and temporal distribution of lithics, faunal remains, phytoliths and wood ash, interpreted with the aid of ethnoarchaeological data and comparison to other Palaeolithic sites in the region. Post-depositional disturbance seems to be minimal at Neve David and we therefore suggest that the spatial distribution of the finds mostly represents human use of space. Throughout the thick sequence of occupation episodes, distinct division of space and well-preserved trampled occupation surfaces are generally lacking. We suggest that this pattern represents reduced mobility, as prolonged human activity blurs the primary depositional signal of the activity remains. The density of the finds generally increases in the upper layers of the site. Accordingly, we hypothesize that at the beginning of activity, the duration of occupation was longer and only later in the sequence of events was there an increase in group size. Our findings further highlight the position of the Geometric Kebaran as a pivotal stage in understanding the gap between the preceding highly mobile societies and the succeeding sedentary and demographically-larger Natufian societies.

The aim of this paper is to present the methodology used to study the megalithic architecture of Menjez's monuments (Akkar, Lebanon), as part of the MEG-A Project - "First megalith builders in the northern Levant" (2022–2025). Twenty-four monuments have been investigated since 2018. The primary objective is to pioneer a comprehensive understanding of the unique Levantine megalithic building techniques and re-establish the "chaînes opératoires," by determining the builders' sequence of actions. This groundbreaking methodology originally developed for Western European megalithic monuments, notably in Brittany, France, has been innovatively applied and customized to suit the Levantine context, specifically focusing on the distinctive basaltic monuments of Menjez and its surrounding areas. By using photogrammetry as a tool, the researchers are able to de-construct the megalithic architecture by analyzing the different components of these monuments. Moreover, it is then possible to describe monoliths according to their place within the monument and their geological and geomorphological features. Our work has led us to consider the symbolic aspect expressed in the megalithic architecture of Menjez. Employing this groundbreaking methodology not only yields concrete answers regarding the typology of these monuments but also dramatically reshapes our perception of their construction. It establishes a precise relative chronology for the various architectural phases and, most significantly, reveals the hidden details of the raw material supply chain. [ABSTRACT FROM AUTHOR]

Energetic conditions during storms cause major geomorphological changes in coastal environments and drive taphonomic transformations of coastal archaeological sites. Facing the emerging realities of modern climate change and sea-level rise, archaeologists have justifiably focused on erosional processes and the loss of cultural heritage. However, sedimentologists have long recognized that storm-forcing also involves significant (re)depositional processes and the formation of supratidal features. Geoarchaeological research at partially inundated Native American shell mound sites in Tampa Bay, Florida, integrated topobathymetric aerial LiDAR with sub-surface testing to reconstruct complex site-formation histories. These histories include reworking of cultural deposits by contemporary, recent-historical, and ancient storms, forming archaeological tempestites—sediment deposits that have been scoured from and/or deposited within archaeological contexts by storm-forcing. Using sedimentological, zooarchaeological, and radiometric data, as well as post-storm observations, we present methods for recognizing storm-driven redeposition in coastal-estuarine archaeological contexts and demonstrate the potential of archaeo-tempestites for improving archaeological and paleoenvironmental interpretation. Storm-reworking of estuarine shell mounds on the Florida Gulf Coast produces diagnostic signatures in stratigraphy, granulometry, organic content, and mollusk-composition. Ephemeral ground surfaces and overwashed sand-sheets provide suitable loci for radiometric dating of past storm events (14C and OSL). We discuss inter- and intra-site variation among regional archaeo-tempestites to better understand late-Holocene ecosystem transfer and the long-term effects of shell-bearing sites on inshore-estuarine ecological conditions. We consider the absorption of energetic forcing as part of the life-history or use-life of shell-bearing features and suggest that a broader study of Indigenous coastal terraforming may aid modern coastal protection and management efforts.

Cahuachi (Nazca River Valley, South Peru) was the major ceremonial center of the Nasca civilization. According to previous studies, it was struck and destroyed by three El Niño-Southern Oscillation events, which would have occurred around 100 BCE, 600 CE and 1000 CE, respectively. At the end of the series of events, the ceremonial center would have been buried by a cap of conglomerates. Despite this hypothesis raised well-founded doubts regarding its geochronological and paleoenvironmental implications, it is uncritically used as a reference in geoarchaeological research. In the present study, optically stimulated luminescence (OSL) dating results of some samples taken from alluvial deposits at Cahuachi are reported, with the aim to evaluate the literature's hypothesis. Since the obtained ages are older than the Holocene epoch, such a hypothesis must be rejected. A number of field evidences corroborate this result. Finally, the advancement in fluvial geomorphology knowledge of the Nazca River Valley is briefly discussed. [ABSTRACT FROM AUTHOR]

We developed a multi-source, integrated remote sensing approach to characterize the geomorphological features of the alluvial and coastal lowlands around the ancient Abdera (coastal Thrace, Gr.). By combining multi-temporal composites of satellite imagery, DEM-derived products, orthophotography, and different cartographic resources, more than 1000 linear km of ancient landforms have been identified and mapped. When crossed with archaeological and historical data, our results allowed to propose a reconstruction of the palaeogeographic evolution and geomorphological dynamics in the eastern lobe of the Nestos Delta, the Kosynthos plain, Lake Vistonida and the Porto Lagos coast since the Antiquity. Our results suggest that the delta developed mainly between Hellenistic times and the Late Antiquity, when it had reached a shape similar to the current. Most of the large palaeochannels visible in the delta seem to be Nestos' short-lived avulsions occurring in late Byzantine and Ottoman periods. Eastwards progradation of the Kosynthos plain, especially during Byzantine and Ottoman periods and accelerating in the 20th c. due to river channelization, was the main cause of the silting and a significant size reduction of Lake Vistonida since the Antiquity. Lake Lafra was also partially silted in late Byzantine and Ottoman times, likely due to the sedimentary discharge of the Kosynthos after a change in its course. By contrast, other lagoons and wetlands in the coast of Porto Lagos seem relatively stable in the last millennia with only minor silting and coastline progradation. Further geomorphological and geoarchaeological research in the area will allow to draw more precisely long-term interaction of past societies with environmental dynamics and resulting landscape change.

Cave pearls are spherical concentric speleothems growing radially around nuclei in shallow pools saturated with calcite. They are very rare in the Southern Levant. We present a unique assemblage of 50 cave pearls found in the Iron Age Joweizeh artificial spring tunnel in the Jerusalem Hills of Israel. Some of these deposits represent the first global evidence of formation on archaeological artefacts: pottery sherds and ancient plaster. Multi‐analyses were conducted to date and characterize the different nuclei and pearls. Charcoal samples extracted from the plaster nuclei of two pearls were 14C dated to the Hellenistic period. Two pearls were formed on sherds of Hellenistic lamps. XPS found Co colour remains, suggesting both had been imported. The Hellenistic date is also supported by archaeomagnetic dates of seven other pottery nuclei. Most Hellenistic remains are probably the outcome of a renovation campaign in the tunnel. Four pearls were sampled for stable isotopes (δ13C and δ18O). The range of δ18O values from the Joweizeh pearls is compatible with the Holocene Soreq and Jerusalem caves’ records. The δ13C differences between Joweizeh and Soreq indicate local changes in the overlying vegetation throughout history. The various lines of evidence enabled us to characterize the pearls’ formation process, reconstruct the Joweizeh spring tunnel's hydraulic environment and detect changes that occurred in its water flow regime throughout history.

This research presents the findings of a petrographic analysis conducted on pre‐colonial Ceramics from Aruba, focusing on understanding ceramic mineral resources and production. The study compared ceramics from nine sites with a selection of clay sources from the island. Petrographic analysis identified the existence of three different mineralogical compositions. Two groups of undecorated vessels were likely manufactured using locally sourced clay materials. Group 1 ceramics show a connection with the weathering of quartz‐diorite intrusions in the northwest part of the island and suggest the exploitation of multiple, geographically close sources with similar compositions. Group 2 ceramics are related to clay sources found in the southeast of Aruba, with a mixed geological composition, including limestone, volcanic tuff and quartz‐diorite. In contrast, Group 3 ceramics are mostly decorated and belong to the Early Urumaco Period. They display a distinct composition characterized by a calcareous matrix with clay pellets, clay streaks and the presence of shell fragments added as temper. The extensive clay preparation practice leaves uncertainties concerning the origin of ceramics from Group 3. The study also highlights clay selection and use patterns, indicating that different clay sources were interchangeably utilized by communities across Aruba. [ABSTRACT FROM AUTHOR]

A submerged elevation located off the coast of Le Castella, a small village on the Ionian Coast of Calabria (Italy) populated for thousands of years that features notable archaeological remains from the Great Greece (Magna Graecia) and the Middle Ages, was investigated through in-depth, multidisciplinary, geoarchaeological research. This submarine elevation, once aligned with the marine terrace MIS 3 of Le Castella and still completely emerged between 10 and 8 ka years ago, slowly sank due to erosion and local tectonic-structural subsidence and was also favoured by a submerged normal fault that cuts the terrace in two. The dismantling and sinking of this part of the marine terrace has significantly changed the Late Holocene shorelines, with notable consequences on a topographic and archaeological level. In fact, one of the consequences of the sinking of this ancient promontory was the disappearance of two small islands that were reported to be right in front of Le Castella by numerous historical and cartographic sources. In the last decades, there has been a scientific debate over the existence of these islets, but no convincing evidence has been found about their actual presence up until now. This research, funded by the Marine Protected Area "Capo Rizzuto", was conducted by means of underwater archaeological and geological surveys, geophysical seabed mapping systems, and both direct and instrumental optical surveys made with an Autonomous Surface Vehicle. The outcomes allow us to confirm the presence of these two partially emerged rock bodies up to half a millennium ago. In addition, the presence of anthropogenic extrabasinal materials in a marine area corresponding to one of the highest points of the submerged elevation allows us to define the exact position of one of the two islets. These archaeological findings have been subject, for the first time ever, to a thorough topographical and architectural analysis, then compared with other near and very similar submerged structures. On the basis of these comparisons, the findings should be attributed to the Byzantine Age or, at most, to the Middle Ages. In-depth archival research on portolan charts and navigation maps, in many cases unpublished and dating from the Middle Ages to the early 18th century, supports the results of our marine investigations from a historical point of view.

This paper discusses the evolution of human settlement in ancient Macedonia from the Neolithic to the Late Roman periods, based on the results of a new multi-disciplinary and multi-scale archaeological survey in northern Grevena (NW Greece). Building upon an unpublished (legacy) survey, we developed a GIS-structured workflow that integrates site-revisiting and surveying strategies (material collection and test pits) with multi-temporal remote-sensing analyses, offering analytical information about site distribution, characterisation, dating, and taphonomy. Notably, the new study led to a 64% increase in the number of known sites. The combined results indicate that prehistory is less represented in the surface record than historical periods, likely due to the impact of soil erosion episodes. The Late Bronze Age and Early Iron Age saw increased site numbers and the emergence of a settlement structure that characterised the area until the Hellenistic period. During the Roman period, the pattern shifted from a seemingly limited use of the landscape towards a model of more extensive habitation. This was driven by the appearance of new rural sites that introduced a land-use regime designed to support agricultural intensification by implementing anti-erosion measures, such as field terraces.

AbstractThe Caspian Sea, the Earth’s largest lake, straddles the continents of Asia and Europe and has historically served as both a barrier and a conduit for human development. The maritime activities within the Caspian Sea have been profoundly shaped by its dynamic sea-level fluctuations, coastal geomorphology, and climatic conditions as well as the socioeconomic and geopolitical situation. Despite a rich history of navigation and numerous related monuments, there has been a scarcity of research on marine archaeological evidence assessing the influence of historical environmental and socioeconomic shifts on the development of maritime activities in the Caspian Sea. In this study, we employed geohistorical, geoarchaeological, and archaeological methodologies to unearth evidence of maritime activities along the Caspian’s southern coast. We investigated 12 archaeological sites and historical shipwrecks, unveiling their maritime historical and archaeological significance. Our findings indicate that there are two distinct patterns of port migration. The transverse migration of ports has predominantly occurred in reaction to swift changes in Caspian Sea level. Additionally, we have identified a long-term migration of ports from the eastern to the western extremities of the southern coast, driven by geopolitical, socioeconomic, and environmental transformations. Drawing on historical and archaeological insights, and considering contemporary global initiatives aimed at forging east–west and north–south connections through the Caspian Sea, as well as the ongoing climatic changes affecting the Caspian Sea level, we anticipate a forthcoming wave of port migrations along its coastlines.

ABSTRACT The Jurash archaeological site is located on Wādī Bīshah near the city of Khamīs Mushayt in southwestern Saudi Arabia. It has a fort and other remains from the pre‐Islamic period (third century bc to early seventh century ad) and a settlement with two mosques from the Early Islamic period (early seventh to early 11th centuries ad). A survey was conducted for the purposes of identifying the building materials and determining their geographic sources, and also investigating the building methods. It was found that all materials were locally derived and that the fort's outer wall is a typical example of South Arabian fortifications of the first millennium bc. An examination of the site stratigraphy revealed that Jurash has been repeatedly inundated by destructive flash floods from Wādī Bīshah. The timing of these events was largely controlled by global climatic fluctuations, including the Medieval Climate Anomaly and the Little Ice Age. [ABSTRACT FROM AUTHOR]

In this paper, we present the long-term occupation of the Perputxent Valley with the purpose of exploring the factors that could explain the long-lasting and trans-cultural occupation of resilient sites and landscapes for nearly two millennia. The first part describes the archaeological research carried out based on remote sensing and intensive coverage survey methods and geoarchaeological analysis. The characterisation of the intensive agricultural uses has been studied from the geochemical analysis of the soil and sedimentary record. The objective is to reconstruct the palaeoenvironmental processes and the possible evidence of the agricultural practices. This research has identified the residential spaces, the sites and the agrarian land-uses, especially intensive farmlands. The second part analyses the evidence of this long-term settlements in the context of the archaeological, ethnographic and historical record of the region. Understanding these practices of agriculture and land-use can contribute to understandings of what makes societies sustainable. [ABSTRACT FROM AUTHOR]

In the Great Basin and Intermountain West of North America, we still lack a well-stratified and consistently radiocarbon-dated Clovis site, so we cannot completely understand variability in fluted-point technologies and their relationship to the Western Stemmed tradition. To potentially solve this problem, we revisited the Hell'n Moriah Clovis site located in the southern Bonneville basin of western Utah. Geoarchaeological test excavations failed to identify a buried cultural layer, so the Clovis occupation here cannot be reliably dated. Nonetheless, analysis of the small surface assemblage recovered during an earlier study in 1992 as well as additional surface finds in 2021 allow us to definitively ascribe a Clovis designation to the site and to explore Clovis toolstone procurement, technological activities, and settlement behavior in this region of the arid West.

This article presents the results of the geoarchaeological study of earthen building materials used in a Tartessic public building at Casas del Turuñuelo. The construction dates back to the fifth century BCE and is one of the monumental buildings of Tartessic culture, characterized by its complex architecture, prestige goods, and intentional destruction after a feast and animal sacrifice. We applied an integrated methodology combining macro and micro approaches to investigate earthen construction processes, such as techniques, labour organization, workers' specialization, and environmental exploitation. The sample mainly consists of mudbricks, but we also include other forms of earthen materials such as mud plasters, mud mortars, and geological soils for comparison. In total, 64 samples from different building parts were studied through X-ray fluorescence, X-ray diffraction, thin-section petrography, and CHN analyses. The results reveal that the workforce involved in the construction process used different resources and presented different skill levels, but was centrally planned and organized. This study reflects on the communities' knowledge of the environment, the logistic effort and technical skill employed in the building process, and the existence of strong political structures capable of managing the erection of the complex Tartessic buildings.

This study broadens our knowledge of the relationship between the clayey georesources available in northern Apulia and the artisanal production of ceramics. The focus is placed on a collection of 6th and 7th century A.D. pottery found in the domus excavated within the archaeological complex of Canosa San Pietro (ancient Canusium) in Italy. The integration of the results obtained from this study with those already available made it possible to outline conscious technological choices in terms of raw materials' exploitation, based on which the alluvial deposits were selected for the production of coarse cooking ware and the marine Subapennine clays for the production of fine common ware. This selective choice undoubtedly had a practical implication since it supplied raw materials that required little processing, being already suitable for the type of ceramic to be produced. Moreover, the compositional comparison of investigated pottery with products distributed along the Carapelle valley, rather than those from Canusium previously studied, provides new perspectives for reconstructing the microcirculation of ceramics in northern Apulia. Lastly, the imports of Classe‐type pottery, probably from the northern Adriatic area, are worth mentioning since they represent the most consistent distribution of this type of ceramic in southern Italy and may reflect the assiduous pilgrimage of the monastery after the death of Bishop Savinus.

In the Biosphere Reserve of the Maya Lowlands, the large‐scale characterisation of the current wetlands ecology and the exploitation and management of their natural resources by the ancient Maya is severely constrained by the forest. This paper presents an integrated geomatic, geoarchaeological and ecological approach, developed to overcome this obstacle in the microregion of the Naachtun Maya city. It is based on the analysis of LiDAR, and field and laboratory data. This approach has revealed the mosaic of current ecological conditions of the wetlands, thanks to the characterisation and spatial modelling of the landforms, hydrology, vegetation and soil cover. It has enabled the characterisation of numerous hydraulic and agricultural structures: 70 large reservoirs, raised fields (the largest over 1.5 km²), canals and ditches (with a cumulative length of over 300 km) and dikes. Eight morphological types of hybrid structures—hydraulic and agricultural—are described. These constructions have enabled the intensive exploitation of water and soil resources, their management and the resulting environmental risks. This study has shown that the agroecosystems of lowland areas were created as early as ~1500 B.C.E. and evolved in a polyphasic way, until a phase of radical decline around 1000 C.E. This study has made it possible to characterise the legacy of the Maya Early Anthropocene on current wetlands, as well as their important natural and cultural heritage. [ABSTRACT FROM AUTHOR]

The newly constructed Bois d'Arc Lake Reservoir in Fannin County, Texas, USA, inevitably flooded a large ground surface area (67.34 km2) when the reservoir began impounding water in April 2021. Inside this (now) flooded area, land-based archaeological data recovery investigations discovered and documented several archaeological sites, now registered in the state of Texas; though, only two neighboring sites, namely, 41FN178 and 41FN244, are examined here. The first phase of archaeological testing at these sites included shovel testing, test unit excavations, and geoarchaeological trenching that yielded archaeological artifacts suggesting that Middle Caddo Indian peoples (AD 1200–1400) might have occupied this landscape. As the sites were recognized before the reservoir's impoundment phase, this merited a non-invasive, non-destructive, high-resolution near-surface geophysical study to map strategic areas within sites 41FN178 and 41FN244 that might yield potential shallow targets of archaeological context. The adopted geophysical survey comprised 3D direct current electrical resistivity imaging (ERI) and land horizontal magnetic gradiometry (HMG), each mapping a total surface area of 2133 and 15,640 m2, respectively. The combination of 3D ERI and land HMG surveys was instrumental in rapidly mapping the horizontal and vertical extent of shallowly buried anomalies within a large area prior to the completion of the dam and the beginning of water impoundment. Based on the geophysical insights, the outline of several Caddo houses with functional internal and external features (e.g., burnt cooking surfaces, storage pits, refuse pits, fired soil, ditches, a dump site, and a compound fence) are thought to exist within the uppermost 2 m of the Quaternary stratigraphy at both sites. At site 41FN244, 3D ERI found numerous resistive anomalies surrounding a conductive anomaly, collectively interpreted as a group of post-holes surrounding the remains of a Caddo house's inner clay floor. It also found a cluster of several resistive anomalies interpreted as midden or middens. The HMG survey carried across areas from which archaeological test units also yielded positive findings, at sites 41FN178 and 41FN244, identified numerous scattered monopolar and dipolar anomalies interpreted as post-molds of Caddo houses, compound enclosures or fences, and adjacent middens. Archaeological excavations guided by the geophysical results yielded significant cultural material and post-mold features at site 244, which validate the geophysical interpretation in a preliminary context. Additionally, several dispersed magnetic anomalies are thought to be shallowly buried hearths, burn cooking surfaces, storage pits, and ditches. The mapped magnetic anomalies agree with the location and distribution of previously found archaeological artifacts and the extent of resistive and conductive resistivity anomalies. Follow-up archaeological excavations of these geophysical anomalies have preliminarily confirmed interpretations. [ABSTRACT FROM AUTHOR]

A multidisciplinary study, including geomorphological, stratigraphic, paleontological and archaeological methods and techniques, allowed for a detailed exploration of coastal landforms and environments in front of the ancient city of Pompeii (southern Italy). The famous site of Pompeii sits on a small volcanic hill in the alluvial-coastal plain of the Sarno River, very close to the ancient paleoshoreline. When the Roman city was buried during the eruption of Vesuvius in 79 CE, pyroclastic fall and flow deposits covered the urban centres and ancient coastal landforms. In this study, 83 new boreholes were carried out up to a depth of 10 m. Some of them (15) were analysed for their sedimentological, stratigraphical and paleontological characterisation, in order to reconstruct the sedimentary environments in 79 CE. The data collected allow for new hypotheses to be formulated regarding the paleoshorelines, as well as the 79 CE coastal landforms and environments. In particular, litho-stratigraphic and fossil assemblages highlight the presence of shallow marine environments in a large back-ridge depression, named Masseria Curati, that is located just outside the city walls. This hypothesis opens new insights on the unknown location of the harbour of the Roman city. [ABSTRACT FROM AUTHOR]

The aim of this paper is to present the archaeological data that allows us to characterise the agrarian practices of Roman farmers through the study of cultivated fields. To undertake this research, we designed an analytical strategy combining spatial analysis, microstratigraphic analysis through soil micromorphology and physical-chemical analyses of bulk soil samples, and archaeobotanical analyses including palynology, phytoliths and geochemical analysis. All this has allowed us to obtain data of interest for the reconstruction of agrarian land use and to establish a methodological basis for developing future research. This high-resolution, multiscalar, and multianalytical approach pursues to characterise these archaeological contexts to singularize intensive agricultural practices developed in terraced field. The creation of this Roman peasant landscape is related to a specific models of socioeconomic organisation of agricultural work based on the household and its workforce as a determining vector in agrarian intensification.

Archaeologists have developed tools to reconstruct the locations of farming and animal herding using ecological and digital modeling of ancient landscapes. The determination of where on a landscape farming and herding took place, however, can remain elusive in environments with evidence for substantial geomorphological and/or ecological change since the period of occupation. Archaeobotanical and geoarchaeological evidence from the site of Gordion, in central Anatolia, indicates substantial landscape change over the last 4000 years, including deforestation, overgrazing, erosion, and alluviation. These have been inferred to be the result of past agricultural practices, but no firm evidence has pointed to specific locations (geographic and temporal) where ancient farming and herding may have caused these changes. Integrating extant archaeobotanical, zooarchaeological, and geoarchaeological evidence with new isotopic data provides a more detailed reconstruction of the sequence of agricultural practices that shaped the present landscape and ecology of the region, offering a model for future archaeological research within substantially transformed landscapes.

The integration of archaeological, historical and geoarchaeological records represents a significant contribution to research into the medieval landscape. This study focuses on the medieval field system in the deserted village of Debrné, located in northeastern Bohemia, Czechia. The village features a well‐preserved croft plužina field system, a typical historical landscape of central Europe. The main and most visible elements of the field system are the earthen field boundaries, which were the focus of the geoarchaeological investigations. Archaeological excavations in trench S1 revealed a collection of larger stones at a depth of 1 m, potentially serving a drainage function akin to the observed plužina. Additionally, a boulder paving, identified as a remnant of a path between fields, provided insights into the historical use of the area. In trench S2, positioned closer to the village's core, layers with increasing stone content were recorded at a depth of 130 cm. However, the drainage structure observed in trench S1 was not replicated. The dating of earthen field boundaries indicated the creation of the terrace in the second half of the 16th century in trench S1. In trench S2, radiocarbon dating at a depth of 70 to 80 cm ranged from 1025 to 1175 A.D., predating the first written source about Debrné. Optically stimulated luminescence (OSL) dating in trench S2 suggested exposure to sunlight during the third century A.D. Archaeobotanical analysis of charred macroremains from trench S1 revealed 236 plant macroremains belonging to approximately 20 taxa, showcasing wild‐growing, collected useful species such as raspberry, blackberry and elderberry. Trench S2 yielded 23 plant macroremains belonging to 11 taxa, with similar species as trench S1. Pedological and micromorphological examinations displayed distinct layering in both trenches, showing up to six layers. Micromorphological analysis unveiled vuggy microstructures, varying grain sizes and elemental patterns, shedding light on different periods of occupation. Multidisciplinary investigations of the buried soils forming the earthen field boundaries discovered that the original soil cover comprised automorphic lixisols and cambisols, which also form under present conditions. These results underscore the importance of integrating pedological, geoarchaeological, archaeobotanical and physical data to comprehend the intricate nature of anthropogenic landscape changes.

As the Northern Australia Quarantine Strategy (NAQS) approaches its thirty-fifth year of operations, we outline the Australian Government's approach to address extraordinary natural and human mediated biosecurity challenges across our sparsely populated northern shores. NAQS is a concept that is unique worldwide but could be equally well applied in many other island nations dealing with similar circumstances. Key to the success of the NAQS has been long collaborations with biosecurity scientists in the neighbouring nations to the north. Some examples of how these relationships have borne fruit as we tackle regionally important plant diseases are illustrated. We also focus on how the plant pathology component of the program developed and evolved from the early 1990s to 2023. This is the story of how the Australian Government has been protecting Australia's remote northern coastline from biosecurity invasions from neighbouring countries. It is a story of boots on the ground plant health surveillance across Australia's north and also over the horizon, in the countries that lie so close to our northern shore. Key to success has been collaborative field work overseas, with biosecurity scientists of Indonesia, Timor Leste, Papua New Guinea and Solomon Islands. Photograph by Kerry Trapnell.

Over the past several decades, a large corpus of studies has been published on the relationship between resource availability and settlement in coastal Mesoamerica, particularly regarding the prevalence of mixed subsistence systems early in the Formative Period (ca.1800–850 BC). Few recent comparative works, however, are available which draw together research on coastal human–environment interactions from several Mesoamerican regions. This article endeavors to contribute toward interregional comparisons by highlighting findings from case studies in this special section of The Journal of Island and Coastal Archaeology. I explore broadly relevant themes, including geomorphic impacts on the archaeological record and the significance of coastal resources to coastal settlement, subsistence, and trade. While common patterns illuminate archaeological debates, it is important to identify the distinctive environmental characteristics of different regions which impact the visibility of archaeological data as well as the resources available to local populations. I emphasize the utility of conducting high-resolution interdisciplinary research to capture such ecological variability. [ABSTRACT FROM AUTHOR]

Combustion features are routinely studied using micro-geoarchaeology in prehistoric sites, providing information on human social life. In submerged prehistory such features have not been studied from the microscopic perspective, and here we present a study of three combustion features from two submerged Neolithic sites from the southeastern Mediterranean: Atlit-Yam (ninth-millennium cal BP) and Neve Yam (eighth-millennium cal BP). Mineralogical analyses were utilized to detect heated clay while quantification of phytoliths, ash pseudomorphs, and dung spherulites allowed determination of fuel sources. Micromorphology was deployed to determine whether or not the features represent in situ combustion activities and to understand formation processes. Two installations from Atlit-Yam contain evidence for short in situ fire events that were fueled by wood and reached 700–900 °C. One installation from Neve Yam contains reworked deposits that bear evidence for combustion at 500–700 °C, includes remains of wood ash and livestock dung. However, this feature cannot be identified with certainty as an in situ combustion feature. This research shows that pyrotechnological, functional, and social information can be gleaned from underwater combustion features using a micro-geoarchaeological approach and techniques.

Coastal and underwater archaeological sites pose significant challenges in terms of investigation, conservation, valorisation, and management. These sites are often at risk due to climate change and various human-made impacts such as urban expansion, maritime pollution, and natural deterioration. However, advances in remote sensing (RS) and Earth observation (EO) technologies applied to cultural heritage (CH) sites have led to the development of various techniques for underwater cultural heritage (UCH) exploration. The aim of this work was the evaluation of an integrated methodological approach using ultra-high-resolution (UHR) bathymetric data to aid in the identification and interpretation of submerged archaeological contexts. The study focused on a selected area of the submerged Archaeological Park of Baia (Campi Flegrei, south Italy) as a test site. The study highlighted the potential of an approach based on UHR digital bathymetric model (DBM) derivatives and the use of machine learning and statistical techniques to automatically extract and discriminate features of archaeological interest from other components of the seabed substrate. The results achieved accuracy rates of around 90% and created a georeferenced vector map similar to that usually drawn by hand by archaeologists. [ABSTRACT FROM AUTHOR]

Natural events (floods, earthquakes, landslides, etc.) may significantly damage archaeological sites, and therefore reducing their exposure to such events represents a priority for protective and conservation activities. The archaeological Sanctuary of Pachacamac (SP; 2nd–16th century CE; Peru) covers an area of 465 hectares and includes roads, enclosures, huacas with ramps, temples, and palaces located along the central coast of Peru. This area is affected by heavy rain and winds related to the El Niño–Southern Oscillation and to intense solar radiation. We use a 30 cm resolution Digital Surface Model obtained from orthophotogrammetric data and perform a morphometric analysis using geomorphological, hydrological, and climatic quantitative parameters. Our aim is to identify the zones exposed to water flow or stagnation during rainfall, as well as the exposure to winds and solar radiation. The calculated parameters are subsequently processed with an object-based image analysis approach to identify areas with higher climate exposure. We show that the SP architectural layout controls the exposure to water stagnation or flow in the form of rainfall, whereas exposure to wind and solar radiation mainly depends on the topography of an area (e.g., the presence of hills and plains). The methodological approach proposed here may be applied and extended to other archaeological sites. [ABSTRACT FROM AUTHOR]

The potential applications of microCT scanning in the field of archaeobotany are only just beginning to be explored. The imaging technique can extract new archaeobotanical information from existing archaeobotanical collections as well as create new archaeobotanical assemblages within ancient ceramics and other artefact types. The technique could aid in answering archaeobotanical questions about the early histories of some of the world's most important food crops from geographical regions with amongst the poorest rates of archaeobotanical preservation and where ancient plant exploitation remains poorly understood. This paper reviews current uses of microCT imaging in the investigation of archaeobotanical questions, as well as in cognate fields of geosciences, geoarchaeology, botany and palaeobotany. The technique has to date been used in a small number of novel methodological studies to extract internal anatomical morphologies and three-dimensional quantitative data from a range of food crops, which includes sexually-propagated cereals and legumes, and asexually-propagated underground storage organs (USOs). The large three-dimensional, digital datasets produced by microCT scanning have been shown to aid in taxonomic identification of archaeobotanical specimens, as well as robustly assess domestication status. In the future, as scanning technology, computer processing power and data storage capacities continue to improve, the possible applications of microCT scanning to archaeobotanical studies will only increase with the development of machine and deep learning networks enabling the automation of analyses of large archaeobotanical assemblages.

This paper explores some challenges of archaeological interpretation and classification through an enclosure at Inchnadamph in Sutherland, northwestern Scotland, a site that has proven difficult to interpret. Despite a small number of archaeological interventions, including topographic and geophysical survey and excavation, the site remains enigmatic. We discuss the different interpretations suggested for the site in turn, concluding that the enclosure does not fit readily into existing classification schemes. This raises issues surrounding the use of classification systems, prior assumptions, and the need for critical thinking in interpretation. These are universal issues, applicable beyond the Scottish example chosen, and this paper highlights concerns and difficulties encountered by all who deal with the classification of sites and monuments. Ultimately, this challenges some of our preconceptions and sheds light on the limits of our knowledge, as well as the limits of our classification systems. [ABSTRACT FROM AUTHOR]

Archaeological heritage worldwide is threatened through deliberate destruction in particular site looting making the location of archaeological sites potentially sensitive data. At the same time, public information about site locations are important for heritage management, as well as agricultural and urban development. Finding a balance between revealing detailed site locations and not providing data at all is a difficult task. Here we provide an approach to obfuscate archaeological site location data facilitated through a Discrete Global Grid System. We then apply the new obfuscation method to the global p3k14c data set. Veiling the locations of heritage sites with a Discrete Global Grid System allows tiered accuracy access for different stakeholders tailored to their respective needs as well as legal constraints and requirements of administrations. Discrete Global Grid System based obfuscation is globally scalable, consistent, reproducible, and can address the current heterogeneity of obfuscation methods. [ABSTRACT FROM AUTHOR]

Along the lower course of the Rioni and several minor rivers, more than 70 settlement mounds (local name: Dikhagudzuba) have been identified by field surveys and remote sensing techniques. They give evidence of a formerly densely populated landscape in the coastal lowlands on the Colchian plain (western Georgia) and have been dated to the Bronze Age. As yet, limited information is available on their internal architecture, the chronology of the different layers and their palaeoenvironmental context. Based on archaeological sources, remote sensing measurements of three mounds and sediment cores from one mound and its closer surroundings, our study presents a review of the relevant literature and reveals the internal structure, distribution and spatial extent of the mounds. Geochemical and sedimentological analyses of element contents (X‐ray fluorescence) and granulometry helped to identify different stratigraphical layers and differentiate between natural facies and anthropogenic deposits; using the Structure‐from‐Motion technique the mounds' dimensions were calculated. The studied settlement mounds had relatively small dimension (varying from 30 to 100 m in diameter) and were similar in their stratigraphy. Measurement of elements that can identify types of human activity, notably metals and phosphorus, suggest changing intensities of human occupation, pastoral agriculture and metalworking through the occupation sequence. According to the 14C chronology, the formation of the settlements occurred during the first half of the second millennium B.C., which confirms the archaeological interpretation of their Bronze Age origin. The narrow age difference between the lowermost and uppermost anthropogenic layers indicates an intentional construction of the mounds, rather than a successive accumulation of construction debris due to the disintegration of loam bricks by weathering. Therefore, they are indeed mounds and not tells. It is most likely that the characteristic circular moats that surround them were the source of their construction material. Fluvial and alluvial processes in a warm and humid climate dominated the environment of the mounds. [ABSTRACT FROM AUTHOR]

Umhlatuzana rockshelter is known for its continuous record of Middle and Later Stone Age lithic assemblages. This study presents multiproxy geoarchaeological data (micromorphology, X‐ray diffraction and scanning electron microscopy with energy‐dispersive spectroscopy) to reconstruct the depositional and post‐depositional history of the site. Although the Stone Age deposits macroscopically appear homogeneous, micromorphological analysis reveals the existence of primary, unaltered depositional microlayering throughout the sequence. Sediments related to combustion activities on‐site are observed in both the Holocene and Pleistocene deposits. Post‐depositional geochemical alterations result in the formation of several phosphatic minerals that significantly affect the site's preservation conditions. One of those is vashegyite, a rare magnesium phosphate mineral related to acidic and moist sedimentary environments. Bioturbation features are prominent at the microscale, but sediment mixing does not seem to affect the vertical distribution of the artifacts. The observation of horizontal microlayering in both the Pleistocene and Holocene illuminates the dominant mechanism of sedimentation throughout the site's 70,000‐year occupational history. It moreover shows that the lithics can be analysed as coherent assemblages. [ABSTRACT FROM AUTHOR]

A sedimentary investigation was carried out into the rise and fall of mediaeval Bruges' maritime access. Because the mediaeval metropolis had no direct connection with the North Sea, its maritime connectivity during the High- and Late-Middle Ages depended on a tidal channel, known as the 'Zwin'. In order to reconstruct the mediaeval physical environmental situation correctly, the entire Holocene sedimentary record was studied through undisturbed mechanically-drilled cores and electrical cone penetration tests (CPT-e). A detailed sedimentary analysis was complemented with radiocarbon dating and datable archaeological finds to resolve a timeframe for the sedimentary evolution. Tidal channel systems with diverse morphologic and sedimentologic characteristics prevail and cover a period from at least the Roman period till the Late-Middle Ages. The presence of a single peat layer directly on top of the Pleistocene substrate and the stratigraphic position of the tidal channel deposits relative to this peat layer, proves that no seawater entered this part of the Belgian coastal plain before the Late-Holocene. The tidal channel system that was active during the heydays of Bruges (the Zwin) was the last natural one. It silted up due to a further reduction of the accommodation space as a consequence of new embankments, possibly expedited by storms. [ABSTRACT FROM AUTHOR]

The route and speed of migration into Sahul by Homo sapiens remain a major research question in archaeology. Here, we introduce an approach which models the impact of the physical environment on human mobility by combining time-evolving landscapes with Lévy walk foraging patterns, this latter accounting for a combination of short-distance steps and occasional longer moves that hunter-gatherers likely utilised for efficient exploration of new environments. Our results suggest a wave of dispersal radiating across Sahul following riverine corridors and coastlines. Estimated migration speeds, based on archaeological sites and predicted travelled distances, fall within previously reported range from Sahul and other regions. From our mechanistic movement simulations, we then analyse the likelihood of archaeological sites and highlight areas in Australia that hold archaeological potential. Our approach complements existing methods and provides interesting perspectives on the Pleistocene archaeology of Sahul that could be applied to other regions around the world. The speed and route by which Homo sapiens colonised Sahul is an ongoing topic of research. Here, the authors model the physical environment as it changes through time in combination with Lévy walk foraging patterns to suggest a wave of dispersal following coastlines and rivers.

This paper demonstrates the utility of ground‐penetrating radar (GPR) to inform forensic archaeology recovery efforts of missing service members from historic conflict‐related aircraft crash sites. This approach is becoming more common and improving recovery strategies by pinpointing potential subsurface anomalies prior to excavation. Two examples of recovery efforts at WWII aircraft crash sites are presented, revealing the diversity of landscape upheaval signatures that result from aircraft impacts. In both situations, the GPR successfully located feature boundaries and identified aviation impacturbation. The landscape signature varied in both cases due to factors including the trajectory and velocity of the aircraft crash and the topography of the impacted landscape. Notably, a 'halo' effect was identified in association with one crash site, revealing the force of the impact on sandy soils. Recognition of these anthropogenic signals is important to promote effective recovery strategies, thus saving time, labour and funds, particularly in historic sites where postincident taphonomic conditions have severely altered the morphology of the landscape.

This paper presents comparative research on marine shell from four 19th century historical archaeological sites in Melbourne. The shell derives predominantly from Mud Oyster (Ostrea angasi) and Sydney Rock Oyster (Saccostrea glomerata) commercially harvested from natural reefs along the south‐east Australian coastline. The research collects quantitative data that informs on the 19th century oyster industry and investigates inter‐site shell variability and its implications for processing, consumption and discard. Dredging of subtidal reefs provides an explanation for the numerical dominance of oyster, the presence of subfossil cultch (Anadara) and the wide range of minor shellfish. Mud oyster and Sydney rock oyster comparisons in valve size, sided counts and preservation record significant differences within and between sites due to the origins, depositional conditions and the processing of the shell. These data form the basis of two models. The first predicts the archaeological representation of reef dredging and ranks shellfish according to categories, from live oysters to dead shell sampled from the reef substrate. Based on oyster shell anatomy and the separate uses of the right (lid) and left (dish) valves, the second model considers how oyster processing and consumption is characterised archaeologically in differential valve counts and pairing rates.

The possible co-variation of human occupation and vegetation from the Middle Neolithic to the beginning of the Iron Age (7.5–2.8 ka BP) in Central Sicily in the context of the central Mediterranean between Middle and Late Holocene are analysed in this paper to provide new insights on Sicilian prehistoric demography. The demographic and economic trends during these millennia were reconstructed using archaeological, Accelerator Mass Spectrometry 14C dates, palynological, archaeobotanical, and zooarchaeological data from the northern, central, and southern sectors of Central Sicily through a diachronic comparison with variation in Arboreal Pollen, Anthropogenic Pollen Indicators, Olea-Juglans-Castanea pollen, microcharcoals, and Sporormiella from four pollen cores from sites in different ecosystems. A very significant spread of farming activities was found at the end of the Neolithic, together with an apparent demographic gap during the Middle Copper Age, and the emergence of agricultural landscapes at the end of the Copper Age associated with a striking increase in population. A combination of cultural and climatic changes during the late phase of the Bronze Age resulted in a subsequent overall decrease in population. [ABSTRACT FROM AUTHOR]

Characterizing permafrost is crucial for understanding the fate of arctic and subarctic archaeological archives under climate change. The loss of bio-physical integrity of archaeological sites in northern regions is still poorly documented, even though discontinuous permafrost is particularly vulnerable to global warming. In this study, we documented the spatial distribution of the permafrost-supported Inuit archaeological site Oakes Bay 1 on Dog Island (Labrador, Canada) while employing a novel approach in northern geoarchaeology based on non-invasive geophysical methods. ERT and GPR were successfully used to estimate active layer thickness and image permafrost spatial variability and characteristics. The results made it possible to reconstruct a conceptual model of the current geocryological context of the subsurface in relation to the site topography, hydrology, and geomorphology. The peripherical walls of Inuit semi-subterranean sod houses were found to contain ice-rich permafrost, whereas their central depressions were identified as sources of vertical permafrost degradation. The geophysical investigations were used to classify the permafrost at Oakes Bay 1 as climate-driven, ecosystem-protected permafrost that cannot regenerate under current climate conditions. This work highlights how the permafrost at Oakes Bay 1 is currently affected by multi-point thermal degradation by both conduction and advection, which makes it highly sensitive to climate warming.

Archaeological evidence for local environmental change is obscured by the tendency for humans to remove natural resources from places of procurement and deposit them elsewhere, sometimes at great distance. This is especially problematic for changes in relative sea level, which clearly affected the inhabitability of low-elevation coastal landforms but not necessarily the regional availability of resources of cultural or economic value. Needed are proxies for relative sea level from non-dietary taxa. One genus of terrestrial snails, Truncatella, offers good potential in this respect because of its specific niche at the interface between seawater and land. However, like food resources displaced by people, Truncatella shells are displaced by storms and redistributed landward of the coastline. Distinguishing between autochthonous and allochthonous deposits is essential to inferring relative sea level from the occurrence of this taxon alone. To this end, assemblages of Truncatella shell from stratified sites along the north Gulf Coast of Florida, USA are compared to associated archaeological snails of other taxa and to snail shells from the wrack of proximate foreshores to infer changes in relative sea level over the past four millennia. Variation in the morphology of shorelines and in the accumulation rates of archaeological midden mitigates any direct relationship between terrestrial snail frequencies and sea level, but the results of this study suggest that our approach can be applied to other non-dietary taxa occupying marginally terrestrial niches to refine estimates for sea level derived from the sedimentary records of geological cores.

In the American Southeast, the most widely cited chronologies place the first appearance of stemmed-based points at the onset of the Middle Holocene (∼8200 calendar years ago), much later in comparison to the Great Basin and Pacific Northwest, where stemmed points appear to be co-eval with the Clovis culture (∼13,000 calendar years ago), or even older. However, the stemmed "Jude" point found in northern and central Mississippi may be an exception from the American Southeast that pre-dates the Middle Holocene. Here, we briefly review the available information on the chronological position of stemmed bifaces in the region and report the results of recent excavations from the Hester site (22MO569) in Amory, Mississippi, where Jude points have been recovered from a dated, Early Holocene context. Consequently, we argue that this type may be among the earliest stemmed varieties in the American Southeast. [ABSTRACT FROM AUTHOR]

This integrated pedo-geoarchaeological study focuses on three abandoned prehispanic terrace agricultural systems near Laramate in the southern Andes of Peru, aiming to unravel the pedological and land-use history of the region. The investigation involved contextualizing the former agricultural management system within its paleoecological framework and assessing the impact of agricultural practices on soil development and quality. The Laramate terrace complex, with its diverse terrace systems and varied geomorphological settings, provided an ideal setting for the investigation. Comparative analyses between non-irrigated agricultural terrace soils and undisturbed reference sequences were conducted, employing a range of methodologies, including surveys, soil analysis, GIS and remote sensing, palaeobotany, and radiocarbon dating. The study identifies three WRB Reference Soil Groups in the Laramate region: Phaeozems , Andosols , and Anthrosols. Unique characteristics of Phaeozems challenge typical descriptions, influenced by factors such as climatic seasonality, vegetation, fauna, lithology, and aeolian inputs. Despite long-term use, terrace soils (Anthrosols) show no severe degradation, maintaining balanced acidity and nutrient availability for successful crop cultivation. Tillage horizons of all terrace soils exhibit elevated organic matter content, highlighting the sustainability of prehispanic agricultural practices through a consistent application of organic manure. Phytolith concentrations indicate extensive agricultural activities, particularly maize cultivation, with varying patterns suggesting changes in cultivation or fertilization practices over time. Starch grain identification aligns with phytolith analyses, reinforcing maize's significance in the region. Notably, the abandonment of the prehispanic cultivation system was not linked to soil exhaustion or terrace instability. The prehispanic history of terraced agriculture in the Laramate region extends over four development phases, reflecting dynamic interactions between environmental, cultural, and agricultural factors. The initial phase, from the Formative Paracas period to the Early Nasca period (800 BCE–200 CE), witnessed the establishment of agricultural terraces with simple terrace architecture, while the Middle Horizon (600–1000 CE) saw systematic areal expansion influenced by the Wari culture. Adaptations to drier conditions included terraced agriculture on volcanic soils. The Late Intermediate Period (1000–1450 CE) witnessed hydrological variability and further terrace expansion to lower altitudes and less agriculturally suitable locations. The final phase, marked by the onset of the Hispanic colonial period in 1532 CE, saw the gradual abandonment of terraced agricultural systems due to demographic shifts and reorganization of production systems. Despite this, the historical trajectory underscores the adaptability and resilience of prehispanic communities in the Laramate region, showcasing innovative terrace agriculture as a means of coping with changing environmental conditions across diverse landscape units.

Taking a long-term perspective of desert pastoralism as an adaptation to changing social and environmental circumstances, a brief history of the phenomenon based primarily on archaeological research examines five different aspects of desert pastoralism using the Negev as a case study. These aspects are: 1. Changing species of exploitation, 2. Varying patterns of seasonal behaviors, 3. Dynamic trends in territoriality and demography, 4. The impacts of fluctuating climates, and 5. Variability in the relationships between desert pastoral societies and their sedentary cousins. Long term trends identified include cumulative species exploitation, linked to diversifying functions of animals in the pastoral societies, the increasing role of social factors in the determination of patterns of seasonal behavior, fluctuating patterns of demography tied to changing patterns of territoriality, with periods of fluorescence and nadir, but increasing site numbers and sizes with each period of fluorescence, and ever intensifying ties to the settled zone in those periods of fluorescence. Variability tied to climatic and environmental change is complex, tied to the fundamental flexibility of pastoral adaptations, changing economic inputs from the settled zone, and the fundamental mosaic of desert environments. Adaptations may be nuanced, and climatic fluctuations are not linked in one-to-one relationships with social prosperity or decline. [ABSTRACT FROM AUTHOR]

The ARGO-USV (Unmanned Surface Vehicle for ARchaeological GeO-application) is a technological project involving a marine drone aimed at devising an innovative methodology for marine geological and geomorphological investigations in shallow areas, usually considered critical areas to be investigated, with the help of traditional vessels. The methodological approach proposed in this paper has been implemented according to a multimodal mapping technique involving the simultaneous and integrated use of both optical and geoacoustic sensors. This approach has been enriched by tools based on artificial intelligence (AI), specifically intended to be installed onboard the ARGO-USV, aimed at the automatic recognition of submerged targets and the physical characterization of the seabed. This technological project is composed of a main command and control system and a series of dedicated sub-systems successfully tested in different operational scenarios. The ARGO drone is capable of acquiring and storing a considerable amount of georeferenced data during surveys lasting a few hours. The transmission of all acquired data in broadcasting allows the cooperation of a multidisciplinary team of specialists able to analyze specific datasets in real time. These features, together with the use of deep-learning-based modules and special attention to green-compliant construction phases, are the particular aspects that make ARGO-USV a modern and innovative project, aiming to improve the knowledge of wide coastal areas while minimizing the impact on these environments. As a proof-of-concept, we present the extensive mapping and characterization of the seabed from a geoarchaeological survey of the underwater Roman harbor of Puteoli in the Gulf of Naples (Italy), demonstrating that deep learning techniques can work synergistically with seabed mapping methods.
