AbstractLarge-scale archaeological surveys in coastal areas can be challenging. Factors such as remoteness, logistics, accessibility, and weather conditions can render fieldwork time-consuming and expensive in rugged archipelagic settings. Remote sensing encompasses several methods that can be used for increasing the survey area and promoting new archaeological insights. Moreover, it can be an affordable option. Google Earth (among others) collects aerial and satellite imagery from third parties and makes them freely available from anywhere in the world. In southern Tierra del Fuego, clusters of ring-shaped shell middens are conspicuous archaeological features. They are abundant in the central part of the Beagle Channel, but it has not been feasible to study their distribution across the Fuegian archipelago because we lack data from many remote areas where fieldwork is not easily conducted. Remote sensing provides a viable option for large-scale surveying due to the general visibility of these midden clusters. In this study, we establish confidence in open access satellite imagery identifications of ring-shaped middens in Tierra del Fuego based on comparisons with UAV LiDAR and conventional ground surveys, arguing that the results are appropriate for studies of large-scale trends. We provide the results from a full desk-based survey of satellite imagery provided by Google Earth, ESRI, and Microsoft Bing, covering 3000 km of coastline up to 1 km inland in southern Tierra del Fuego. Moreover, we determine the geographical distribution of ring-shaped middens and explore large-scale trends in coastal settlement patterns and landscape use—showing that ring-shaped middens are not evenly distributed across the Fuegian archipelago but strongly related to the sheltered areas of the Beagle and Murray Channels.

Insects play a crucial role in cadaveric decomposition, yet their contribution to taphonomic alterations on bones is often overlooked. This study investigates insect activity's impact on bone surface modifications under different environmental conditions. Five unfleshed pig heads were subjected to varied settings—buried and exposed—across coastal and inland contexts. Nine insect taxa were identified, including flies (Sarcophagidae, Calliphoridae [Chrysomia albiceps], Fanniidae, Muscidae), beetles (Dermestidae [Dermestes maculatus], Cleridae [Necrobia rufipes], Hydrophilidae [Cercyon cf. arenarius]), ants (Formicidae [Tetramorium depressum]), and termites (Kalotermitidae [Cryptotermes brevis]). Taphonomic changes observed on bone surfaces varied between buried and exposed specimens, with greater insect diversity and more pronounced modifications in exposed samples. Striations, linear marks, perforations, and bone destruction were linked to specific insect taxa, revealing novel osteophagic behavior in certain species. Termite activity, identified by faecal pellets, occasionally resulted in bone damage. Notably, beetle-induced alterations were absent in coastal environments, suggesting post-decomposition transport when these modifications appear on bone elements from coastal sites. This is the first experimental study in archaeoentomology, providing critical insights into insect-driven taphonomic processes in coastal and inland archaeological sites, with implications for forensic and archaeological interpretations of bone alterations.

Mound Key (8LL2), a 51 ha anthropogenic island in Estero Bay, Florida, is comprised of a complex arrangement of midden-mounds of various sizes, canals, watercourts, causeways, and other features. Occupied from approximately a.d. 450 through European contact, Mound Key served as the primary center and political capital of an extensive Calusa socioeconomic network whose economy was rooted in fishing, gathering, and hunting. Drawing on zooarchaeological analyses of ichthyological refuse dating to between a.d. 1000 and 1350, I argue that the Calusa actively managed and invested in a core fishery that ultimately contributed to a complex, robust socio-ecological systems (SES). I examine the nature, role, and signatures of these fisheries, as their management underwrote the success of Calusa social, political, and economic systems. [ABSTRACT FROM AUTHOR]

Lighthouses are enduring symbols of maritime heritage, representing the history and identity of coastal communities. Over the last few decades, however, these structures have been increasingly decommissioned and divested especially in response to the rise of navigational technologies and costly maintenance. Remarkably little academic scrutiny has been paid to the present and future challenges of these sites, and even less attention has been given to contexts of lighthouse closure, reuse, and replication. In response, this paper combines lighthouse infrastructure data with media analyses and qualitative interviews to explore the 'afterlives' of Canada's historic lighthouses, examining their transformations and the cultural politics involved in their reuse and replica (or faux lighthouses). We argue that historic lighthouses are not only significant features of maritime heritage but also serve as contemporary sites of coastal change and growth. By studying their afterlives, the paper sheds light on the intricate and complicated lifecycles of lighthouses and the communities that depend on them. Overall, we contribute to a broader understanding of coastal heritage, emphasizing the importance of examining adaptive reuse and the emergence of replica lighthouses as practices that renegotiate established values, meanings, and emotions associated with these iconic structures.

Coastal erosion and sea level rise has become a significant threat to coastal heritage due to climate change. Management bodies are monitoring the risks posed by undertaking studies, ranging from Rapid Coastal Zone Assessments to much larger government and research council funded studies. These studies have incorporated varying techniques and datasets such as environmental sampling, LiDAR, GPS, and UAV surveys. However, these approaches rarely combine study of historic shoreline change with physical susceptibility modeling. This paper presents a combined methodology, utilizing LiDAR and survey data collected by the Climate, Heritage, Environments of Reefs, Islands and Headlands (CHERISH) project, along with historic mapping and aerial photography to produce a risk assessment for the heritage assets located on Ynys Enlli (Bardsey Island), North Wales. By constructing an Historic Erosion Model and an Erosion Susceptibility Model using ESRI's ArcGIS 10.5.1. with the DSAS Plugin and combining them with the LiDAR-derived spatial extents of archaeological features on the island, this project has shown that using both methodologies alongside each other can create a more complete overview of coastal environment change for the creation of vulnerability indexes.

Coastal hazards threaten properties, infrastructure, and cultural sites around Aotearoa New Zealand's (hereafter Aotearoa) coastline and sea-level rise (SLR) will escalate this problem. At present it is unclear how archaeological sites will be affected by future coastal erosion and inundation. In this paper we combine national-scale archaeological and environmental datasets to provide a first-pass overview of archaeological heritage at risk in Aotearoa. Two key national-scale datasets are utilized: (1) coastal sensitivity index (CSI) developed by the National Institute of Water and Atmospheric Research; and (2) ArchSite, Aotearoa's archaeological site database. The integrated datasets produce insights into the sensitivity of coastal archaeology to SLR and associated hazards, which are vital to planning for the loss of coastal archaeological sites. More than half (∼55%) of recorded coastal archaeological sites around Aotearoa are midden (n = 4938) and about 25% (n = 2271) are earthworks. In total, ca. 12% (9054) of all known archaeological sites are within 1000 m of soft shore shorelines. Of this total, only about 3% (302) of sites are burials, but the loss of these 302 burial sites would have very high cultural impact. Coastal erosion is a particularly important threat to archaeology as it would permanently remove sites, whereas the risk of site removal by coastal flooding inundation is lower. Our results show that about 22% (1954) of coastal archaeological sites are located on landforms that are sensitive to SLR-driven erosion: 29% (2660) of archaeological sites are located on foredune barrier beaches, 23% (2059) on foredune barrier plains, 14% (1283) on beaches, and 9% (808) on beach ridge barriers. This work draws attention to the scale of coastal archaeology in Aotearoa that needs adequate documentation, preservation, and potentially protection in the face of SLR. Robust coastal erosion and inundation datasets are needed to more deeply understand potential SLR-driven impacts on coastal archaeology and provide a scientific foundation for considering future adaptation options.

ABSTRACT Airborne laser scanning (ALS), commonly known as Light Detection and Ranging (LiDAR), is a remote sensing technique that enables transformative archaeological research by providing high‐density 3D representations of landscapes and sites covered by vegetation whose analysis reveals hidden features and structures. ALS can detect targets under trees and grasslands, making it an ideal archaeological survey and mapping tool. ALS instruments are usually mounted on piloted aircraft. However, since the mid‐2010s, smaller laser scanners can be mounted on uncrewed aerial vehicles or drones. In this article, we examined the viability of drone‐based ALS for archaeological applications by utilizing a RIEGL VUX‐UAV22 sensor to capture point clouds with high spatial resolution at the archaeological site of Heloros in Southeastern Sicily, founded by the Greeks in the late eighth century bce. Using this laser scanner, we surveyed over 1.6 km2 of the archaeological landscape, producing datasets that outperformed noncommercial airborne ALS data for the region made available by the Italian government. We produced derivative imagery free of vegetation, which we visualized in GIS using a modified Local Relief Model technique to aid our archaeological analyses. Our findings demonstrate that drone‐based ALS can penetrate the dense Mediterranean canopy of coastal Sicily with sufficient point density to enable more efficient mapping of underlying archaeological features such as stone quarries, cart tracks, defensive towers and fortification walls. Our study proved that drone‐based ALS sensors can be easily transported to remote locations and that in‐house lab staff can safely operate them, which enables multiple on‐demand surveys and opportunistic collections to be conducted on the fly when environmental conditions are ideal. We conclude that these capabilities further increase the benefits of utilizing ALS for surveying the archaeological landscape under the Mediterranean canopy. [ABSTRACT FROM AUTHOR]

The thematic issue of Historical Archaeology explores colonial and postcolonial consequences in the Americas, focusing on case studies of European intrusion and its impact on emerging British and French colonial empires. The articles honor the career of Réginald Auger, a retired archaeology professor from Université Laval, Quebec City, and discuss topics such as culture contact, urbanization, and enslavement across the Americas. The issue is organized geographically, with articles covering Nunavut, Labrador, Quebec, Montreal, French Guiana, and the French Lesser Antilles, emphasizing the commonality of experiences among diverse populations in the Americas. The articles highlight the importance of understanding the lived experiences of actors and communities affected by colonialism, with a focus on Indigenous and enslaved African populations often overlooked in historical archaeology.

Since the 19th century, the study of shell middens has played an important role in archaeological research. Shell midden and broader coastal archaeology have transformed our understanding of human relationships with aquatic habitats, demonstrating the importance of marine environments to human evolution and ecology, the colonization of islands and establishment of maritime trade networks, changing social and political dynamics, and a variety of other issues. During the past two decades, shell midden research has greatly increased, marking an exciting time for new discoveries and heightened collaboration with Indigenous communities. Several key research trends in shell midden archaeology during the past 10–15 years include research on site distribution and temporality, underwater archaeology, historical ecology, terraforming, landscape legacies, and community collaboration. These research trends demonstrate the ways in which shell midden archaeologists are shaping our understanding of the human past and environmental change around the world. [ABSTRACT FROM AUTHOR]

This review aims to summarise the outcomes, methods, and ideas of shellfish seasonality studies of the last 50 years. With the start of using mollusc shells as indicator of seasonal subsistence and mobility, a range of methods and approaches were used to better understand past human use of the marine (and riverine) environment. I have collated information from over 70 studies and over 400 sites to provide and compare information regarding their seasonality, their spatial and temporal distribution, their species of interest, their sample sizes and methods of determining season. In addition, I have selected several case studies that spotlight and emphasise ideas and important aspects of seasonality research which are worth reintegrating into current studies, chiefly among them the reliance on adequate modern reference studies. I further show that even today, the time investment and general lack of modern and local reference studies are one of the major problems in the study of shell seasonality. [ABSTRACT FROM AUTHOR]

Oysters are an almost ubiquitous presence in coastal archaeological sites globally. Southeast Queensland is no exception, with oysters frequently the dominant taxon in midden deposits. It has been estimated the total number of oysters at Booral Shell Mound in the Great Sandy Strait to be more than 5.9 million individuals. This paper moves beyond just the number of oysters to examine the structure of populations within the deposits at two Southeast Queensland sites, Booral Shell Mound and White Patch 3, from an Applied Historical Ecology approach. In doing so, the nature and sustainability of First Nations marine resource exploitation may be determined. Additionally, environmental factors influencing molluscan population dynamics can be elucidated. Historical accounts provide insights into observed collection practices in the early colonial period, as well as the persistence of First Nations oystering and other marine resource exploitation in the mid-late 19th century in response to participation in the wider economy of early Brisbane. Reasons for the late nineteenth-early Twentieth century collapse of Southeast Queensland oyster populations are examined and attempts to revive the oyster industry reviewed.

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]

This paper calls for a maritime turn in critical heritage theory. Drawing on recent work on ocean and maritime ontologies, it takes up the idea of the 'ocean in excess' to argue for a maritime imagination that overcomes the separation of land from water, culture from nature. The paper begins by sketching out the terracentric norms that have come to underpin critical theory around cultural heritage. From there, recent insights on ocean ontologies are cited to show how they can open up new ways of thinking about existing strands of critical heritage work. The second half of the paper turns to the issue of ocean governance and the complex politics that arise from competing ontologies. This provides the foundation for a discussion of the transoceanic heritage discourses that are now emerging, as countries seek regional, come global influence in world affairs. Understanding these and other developments requires moving beyond the earthly, such that we more robustly engage with a multivalent heritage politics that operates across air, water and land.

The archaeology of the immediate coastline of West Africa remains surprisingly little understood, and what research has been undertaken has often focused on questions relating to sea-based interactions and the precolonial polities lying slightly inland. This paper reports the results of excavations on Ohlinhoué, a small lagoonal island in the western Republic of Bénin. A locally manufactured ceramic assemblage was recovered, together with a small suite of artifacts, including glass, metal, shell, and smoking pipes. These archaeological data provide insights into a small-scale, likely fishing and salt-producing community in this area between sea and river. As such, they provide an alternative to historical readings relating to well-known precolonial polities and trade entrepôts that feed popular historical narratives. [ABSTRACT FROM AUTHOR]

The southern Levantine coast was settled continuously for three millennia, from the Neolithic period until its abandonment in Early Bronze Age II, in sharp contrast to inland sites that developed into urbanized cities. This study examines this phenomenon by investigating the pottery production component of the economic systems of two contemporary EB I villages: a shoreline coastal site that was abandoned (Dor South) and an inland site that evolved into an urban center ('En Esur). This pilot ceramic petrography examination shows two distinct strategies, with 'En Esur producing pottery primarily from local raw materials and Dor South relying mainly on imported pottery, potentially weakening the once-resilient coastal system.

Brazilian coastal archaeology is renowned for its numerous and large shellmounds (sambaquis), which had been continuously occupied from at least 8000 to 1000 years cal BP. However, changes in their structure and material culture in the late Holocene have led to different hypotheses concerning their ecological and cultural changes. The archaeological site Galheta IV (ca. 1300 to 500 years cal BP) offers new insights into the complexity of the late coastal occupation in southern Brazil. Our attempt was to determine whether Galheta IV can be classified as a sambaqui site, or if it belongs to a Southern proto-Jê settlement. Here, we reassessed Galheta's collections and applied a multi-proxy approach using: new 14C dates, zooarchaeology, δ13C and δ15N isotopes in bulk collagen and 87Sr/86Srenamel isotopic ratios from eight human individuals, ceramics analysis, and FTIR. The results indicate an intense exploitation of marine resources, with an area designated for processing animals located at the opposite side of the funerary areas. Bone tools and specific species of animals were found as burial accompaniments. No evidence of human cremations was detected. 87Sr/86Sr results indicate that the eight human individuals always lived on the coast, and did not come from the inland. The pottery analysis confirms the association with Itararé-Taquara, but contrary to what was assumed by previous studies, the pottery seems related to other coastal sites, and not to the highlands. In light of these findings, we propose that Galheta IV can be considered a funerary mound resulting from long and continuous interactions between shellmound and Southern proto-Jê populations. This study not only enhances our understanding of the late coastal occupation dynamics in southern Brazil but also underscores its importance in reshaping current interpretations of shellmound cultural changes over time.

Managing archaeological sites requires an understanding of the threats these artifacts face within their temporal and spatial constraints. The historical site of Harireh on Kish Island in the Persian Gulf is one of the sites that played a significant role in maritime exchanges between Iran and remote areas In the 6th to 8th centuries AH. Like many coastal sites, this site has been affected by the consequences of climate change. Understanding and predicting these consequences is crucial for the cultural management of this site. To this end, Landsat images were utilized in conjunction with the DSAS software plugin in a GIS environment to monitor and predict coastal changes along the shoreline of the Old City of Kish between the years 1988 and 2033. Temporal and spatial variations were measured using 123 transects along the shoreline of the Old City of Kish. The research findings indicated that the entire shoreline of the Old City of Kish, particularly the areas exhibiting significant archaeological features, is susceptible to erosion. This erosion is projected to lead to the destruction of a significant portion of the archaeological features between 2033 and 2043. According to the results, currently, 69.84% of the transects are experiencing erosion, a percentage that is likely to reach 91.39% in the next 20 years. Furthermore, erosion estimates for 2033 and 2043 are approximately 22.52 and 30.45 m, respectively. [ABSTRACT FROM AUTHOR]

AbstractThe Persian Gulf is one of the earliest locations where sailing and maritime navigation originated. The Iranian coasts along the northern side of the Persian Gulf have played a key role in maritime history and its development due to the favorable natural and geographical conditions and access to major historical land routes. However, archaeological evidence of ancient ports and maritime activities in this area is scarce and limited to only a few poorly studied sites. This research aimed to identify several potential ancient ports in this region using ground penetrating radar and surface archaeological survey to verify the historical investigations that suggested them as potential ancient ports. The results confirmed that most of the nine suggested sites we investigated had archaeological evidence of maritime activities, but only four of them had buried structures with the others having only surficial evidence. These sites were also threatened by human activity, looting, and encroaching. This study not only highlights the rich and diverse maritime cultural heritage of the northern coast of the Persian Gulf, but emphasizes that more attention and protection needs to be made of this unique heritage, especially in the context of climate change and the need for Iran’s economic diversification.

Archaeological evidence indicates that initial coastal settlement of western South America took place near the end of the Last Glacial Maximum (LGM) when sea level was between 40 and 100 m lower than today. Beginning around 15,000 cal BP, and for roughly the next 8,000 years, sea levels rose, eventually covering these formerly exposed and potentially human-occupied landscapes. We use bathymetric data and the reconstructed global mean sea level curve from the Last Glacial Maximum to the Holocene to describe the paleolandscapes associated with the Late Pleistocene and Early Holocene coastal occupations at five sites located in far southern Peru. We constructed cross-sections perpendicular to the modern shoreline at the various locales to determine the approximate extent of the exposed land surface and the proximity of the communities at the sites of Quebrada de los Burros, Quebrada Tacahuay, the Ring Site, Kilometer 4 (K4), and Quebrada Miraflores to the ocean and various littoral habitats. Our analysis identifies previously undocumented littoral habitats consisting of large, shallow-water bays, significant rocky headlands, and beach habitats. We propose several methods of future research to identify potentially submerged sites and the marine paleolandscape of the study region. Knowing the paleolandscapes contributes to refining Pacific coast migration and settlement models for South America. [ABSTRACT FROM AUTHOR]

In Australia as elsewhere in the world, coastal archaeological sites are increasingly threatened by rising seas and changing storm patterns, along with encroaching human activities. Understanding the geomorphological context is key to understanding the positioning of archaeological deposits in or on coastal landforms, their vulnerability to erosion and their resilience and capacity for longer-term management and preservation. Here we review the dynamics of beach-barrier systems to contextualise the potential of archaeological deposits to survive erosional processes, especially those associated with current and anticipated impacts of climate change. In doing so, we outline a practical logic for zoning coastal landforms and processes by their proclivity to either erode or preserve archaeological deposits, to assist in the planning of management agendas. It is the sediment budgets and how they change in relation to variation in sea level that fundamentally determine the potential preservation of archaeological deposits in coastal beach-barrier environments. We advocate close transdisciplinary collaboration between archaeology, geomorphology and site managers (i.e. Traditional Owners and land-and-sea management agencies) to better understand the wider landscape dynamics of coastal archaeological sites and landscapes.

The Algerian coast is rich in cultural heritage. Many major historical cities and archaeological remains are scattered along its coastline. This cultural heritage is increasingly threatened by the rapid urbanisation that Algeria has experienced in recent years. In 2018 the area of El Hamdania (Cherchell region) was selected as the site of a new commercial mega port. This large construction project will affect a number of archaeological sites located in this region. This paper aims to highlight the archaeological importance of the El Hamdania region and assesses the risks of such a construction to the heritage of the region. The archaeological evidence discussed is based on survey work carried out by members of the Laboratoire d'Études Historiques et Archéologiques (LEHA), an institution that carries out research projects on coastal and maritime archaeology in Algeria.

Participating in an archaeological field school is one of the only educational experiences that nearly all professional archaeologists have during their training. As a result, field schools are uniquely suited to provide experiential education in emerging skills that all archaeologists will need, such as information and data literacies at all stages of the contemporary research and publishing cycle. The "embedded" librarian program in the University of New Brunswick's Downeast Maine Coastal Archaeology Field School is an effective means to deploy that focused expertise to help students better understand the relationship between fieldwork, data, and dissemination. At the same time, being in the field provides librarians with the knowledge to respond more effectively to the complex data management and research needs of archaeologists. We encourage large research projects to consider librarians as specialist members of the research team. [ABSTRACT FROM AUTHOR]

The use of seaweed as fuel has been mentioned in ethnographic and historical sources of different coastal regions. Nevertheless, the archaeological record of seaweed burning is still limited to contexts where preservation is exceptional and macroscopic discrimination of charred remains is possible. Here, we evaluate the effectiveness of Raman spectroscopy in discriminating seaweed vs. plant/wood char. Our dataset (N = 92) consists of modern and archaeological seaweed and plant/wood charred remains, including specimens of unknown origin from the Atacama Desert coast, Northern Chile. The charred samples were processed to obtain 13 parameters which were then fed into five supervised machine learning models. The models, built on samples of known origin (seaweed and plant/wood), performed remarkably well in terms of accuracy, kappa, sensitivity, and specificity. The models were used for final predictions on 10 non-identified archaeological charcoals. Our results suggest that Raman spectroscopy combined with machine learning techniques is a robust methodology for discriminating seaweed and plant/wood charred remains in the archaeological record. The predictions on unknown samples confirm that seaweed was used as fuel in a specific funerary ritual in the southern Atacama Desert coast around 5000 cal BP. Furthermore, charred specimens of Lessonia spp. recovered from combustion features in other northern Chile coastal settlements, suggest that seaweed pyrotechnology developed by Atacama Desert coast people is likely a long-term process. As for coastal archaeology, this work encourages new research on seaweed as an alternative/main fuel in coastal deserts and evaluates possible bias for chronologies from coastal archaeological settlements around the globe.

LiDAR has become fairly integrated into archaeological practice at a global scale. This has gradually evolved to include UAV LiDAR. Nevertheless, considerable biases remain, including with regard to geographical regions, chronological periods, feature types and environments. At present, few studies of coastal environments exist, despite the fact that LiDAR—and UAV LiDAR in particular—has the obvious advantages of flexibility and time efficiency in such archaeologically rich but logistically challenging environments. In this paper, we compare the results of UAV LiDAR surveys with records from previous ground surveys in two case studies from coastal environments on opposite sides of the globe. Case Study I of shell middens located within approximately 3 km2 around Cambaceres Bay involved the first collection of LiDAR data from Tierra del Fuego, Argentina. Case Study II covered approximately 3 km2 of the island of Vega, Northern Norway, and is among the pioneering LiDAR studies of Mesolithic house pits. The detection success rate was fairly good for Cambaceres—69% of 1240 recorded structures were identified on LiDAR—and above expected for Vega, with 81% of 51 recorded house pits identified on LiDAR. In Cambaceres, the main challenges were dense and low vegetation and identifying small middens. Possible new identifications of archaeological features were made in both areas: subtle depressions interpreted as dwelling foundations in Cambaceres and house pits on Vega. We conclude that UAV LiDAR can contribute to coastal archaeology and that it has added values besides making new identifications, being both flexible and time efficient. An example pertains to the possible identification of a practice that has not previously been proved archaeologically in Tierra del Fuego—more thorough site preparation prior to the construction of the dwellings—which in turn raises new questions.

Recent global projections of climate change highlight alarming rates of flooding and erosion on the coastlines of the Middle East and North Africa (MENA). Though there are indisputable links between climate change and the deterioration of maritime cultural heritage (particularly coastal archaeology), deterioration is often the result of multiple compounding factors, central among which are anthropogenic landscape alterations. In this article the authors attempt to disentangle these factors at a small scale, using the Gaza Strip, Libya, and Oman as case studies. They examine the impact of accelerating coastal erosion, flooding, and increasing frequency of tropical cyclones to question predominant discussions on the impact of climate change on heritage. They emphasize methods and practices for the identification of sites that can expand and refine climate change research (often reliant on data from the twentieth and twenty-first centuries) through the long-term perspective archaeology is uniquely placed to offer.

Archaeological heritage is under threat by climate change all over the world and its resulting impacts are happening so quickly and within so many different physical and socio-cultural contexts, that it is impossible for any single organization or discipline to combat. For this reason, researchers have developed various methods and options in engaging the public's help through community-based and citizen science research, including community archaeology and community heritage projects to better preserve our cultural heritage. This paper presents five diverse case studies from Alaska, Scotland, Florida, Australia and Guadeloupe to highlight how collaboration and community archaeology are building better practices to manage coastal archaeological heritage. The case studies are compared and analysed based on underlying components they all share. In the end the most common factors attributing to a successful community archaeology project will be determined and reviewed. [ABSTRACT FROM AUTHOR]

Indigenous communities globally are challenged by threats to heritage resources due to residual effects of colonization, outsider encroachment on traditional spaces, and economic and political inequities. The effects of climate change add another dimension to these challenges, not only by altering familiar ecosystems and landscapes but also through the destruction of Indigenous heritage spaces. The University of Maine's Northeast archaeology program supports Indigenous resilience to climate change through community-engaged approaches to archaeological research. Recent shell heap research at the Holmes Point West site in Machiasport, Maine, exemplifies these efforts by blending archaeological science with service through Passamaquoddy language preservation and community engagement. This article discusses the University of Maine's partnership with the Passamaquoddy Nation and reflects on the nexus of Indigenous archaeology, heritage protection, and climate change resilience.

Archaeology on Oregon's Coast has been largely limited in scope and has lacked the holistic viewpoint of Indigenous coastal history. Investigations began in earnest around 1930 with avocational archaeologists like Marcus Seale interested in expanding their "trophy item" collections. The male dominated field of professional archaeology began to evolve in the 1940s and 1950s with investigators from varying backgrounds, like Luther Cressman who began studying the material culture of the Oregon Tribes as if they were an extinct group. The 1970s push for federal recognition brought increased Tribal involvement and collaboration with archaeologists such as Richard Everett "Dick" Ross. Unfortunately, Tribes remain largely uninterested in archaeology as Indigenous individuals and communities continue to be left out of the narrative. Cultural resource professionals at major institutions continue to curate "cultural material" under the aegis of science and resource protection while arguing against the repatriation of material based on either lack of skeletal components, or a misguided understanding of "affiliation" and of Native views of sacredness. We explore the legacy of our predecessors and how we as archaeologists must take a more comprehensive Tribal perspective approach to understanding Oregon coastal history and more respectfully manage legacy collections.

Maritime adaptation is a key component of the Neolithization process in Eastern Arabia. It is expressed by the development of diversified fishing techniques, the exploitation of hard marine animal materials (e.g., seashells, shark teeth, stingray's barbs, etc.) for both tools and personal adornments production, advanced seafaring, and colonization of offshore islands. Although a diet based mainly on the consumption of marine fish and mollusks, the importance of other seafood has been greatly underestimated in previous zooarchaeological studies. Large quantities of marine crabs (NISP = 10,619) and sea urchins (NISP = 2454) have been retrieved from newly excavated Neolithic sites in the United Arab Emirates. These data highlight local developments of interest for specific seafood and their intensive exploitation over several centuries of human occupation. This study focuses on methods for identifying the main edible marine crab and sea urchin species retrieved from archaeological sites in Eastern Arabia. Results from the Neolithic sites of Delma Island and the Umm al-Quwain lagoon are discussed. [ABSTRACT FROM AUTHOR]

Our ocean planet is home to diverse marine environments and organisms that played an important role in human evolution and ecology. Today, coastal marine ecosystems are dramatically degraded and threatened by climate change, habitat destruction, overfishing, and more, leaving key questions about the future of ocean ecosystems in increasingly unstable times. Archaeology provides perspectives on past marine ecosystems and people's role in shaping and influencing coastal environments prior to the dramatic changes of the postindustrial era. Drawing on archaeological research from the California Coast and the Chesapeake Bay, I explore how an understanding of long-term human interactions with marine ecosystems can help address contemporary environmental challenges and better prepare us for an uncertain future. Although clear examples of archaeological research guiding present-day biological conservation management and policy are limited, there are important signs of success. These include collaboration with Indigenous communities; growing recognition by biologists, ecologists, and other scientists of the significance of archaeological and historical ecological perspectives; and continued emphasis on the links between environmental conservation and social justice.

Thousands of significant archaeological and heritage sites line the coasts of every continent, threatened by loss and damage from rising sea levels and other cascading impacts, such as flooding, landslides, increased salination, erosion, or even the shift from being land-based heritage to being submerged or underwater heritage. There is a need for a sustainable initiative across the national, regional, and local levels to manage this degenerative process. To date, however, measures for mitigating climate change impacts remain insufficient. There is also the need for a further push in thinking about how coastal archaeology and culturally submerged sites may be remembered or, if on the cards, protected. The Coastal and Intertidal Zone Archaeological Network (CITiZAN), a national project working across coastal sites in England, works with communities to support and empower them in identifying and understanding their immediate environment and the relevance of the heritage therein. In this article, the CITiZAN team presents the range of vulnerable coastal heritage found across England, discusses why there is limited capacity or resources to protect these sites, and highlights the communities that have either reactively or proactively responded to changing climate conditions and, in so doing, provide examples of resourcefulness and resilience. The article concludes by highlighting the importance of communities in understanding intertidal-zone and coastal heritage, and the relevance of water heritage to understanding climate change impacts terrestrially.

Coastal erosion in Cyrenaica (Eastern Libya) represents a major problem for archaeology and heritage management. The area is rich in archaeological sites, often understudied or not fully documented, but also has extensive stretches of vulnerable eroding coastline. This study demonstrates the extent and impact of erosion via shoreline change assessment at two spatial scales. Firstly, wide area assessment using shorelines extracted from a time-series of medium-resolution Landsat imagery. Secondly, site-specific assessment using recent and historic Very High Resolution (VHR) satellite imagery. In both cases, extracted shorelines at different timesteps were compared using the Digital Shoreline Analysis System (DSAS) tool to quantify rates and magnitudes of shoreline movement. The results show extensive zones of erosion at and around the key ancient harbour sites of Apollonia, Ptolemais and Tocra. They also suggest increased rates of coastal retreat in recent years, which is likely linked to anthropogenic actions such as sand mining and urbanization. Forecasts based on present-day shoreline change rates, coupled with ground-level documentation of the vulnerable shorelines is used to identify archaeological features and structures which will likely be progressively damaged or destroyed over the next 20 years. The ability to actively protect archaeological sites is unclear, but there is a clear need for mitigation in the form of enhanced awareness of environmental problems (e.g. caused by sand mining) and more intensive survey/documentation of sites and areas which will be lost in the coming years.

Climate change threatens coastal archaeology through storm flooding (extreme sea-level: ESL), long-term sea-level rise (SLR) and coastal erosion. Many regions, like the Middle East and North Africa (MENA), lack key baseline evidence. We present initial results from a climate change threat assessment of MENA's coastal heritage using the Maritime Endangered Archaeology inventory: a geospatial database of MENA maritime archaeological sites incorporating a disturbance/ threat assessment. It informs two analyses of past disturbance and future threat: (1) using the integral threat/disturbance assessment, and (2) geospatial extraction of information from external coastal change models. Analysis suggests <5% of documented coastal sites are definitely affected by coastal erosion but up to 34% could also have experienced past flooding, erosion, or storm action. Climate change-related threats will increase over the 21st Century and accelerate post-2050 if carbon emissions remain high. SLR and ESL could impact 14–25% of sites by 2050 and 18–34% by 2100. Over 30% to 40% of sites could be impacted by erosion by 2050 and 2100 respectively. Whilst documentation is ongoing and there remain modeling uncertainties, this approach provides a means to redress the absence of baseline data on climate change threats to coastal cultural heritage in MENA.
