[EN] The geophysics line at the IGME began in 1927 as a Geophysics Sectiondedicated to subsurface exploration. During all this time, it has been developed in order to support and give expert service in all IGME’s activities both as a geological service and public research institution, as well as a research and development work itself. On the other hand, in recent years the IGME has promoted a line of research aimed at the characterization and 3D modeling of geological structures and formations, the development of dedicated software and the evolution and sophistication of computer equipment. The new scenario of incorporation of the IGME to the CSIC as a national reference center in the field of Earth Sciences has allowed the establishment of the GEOFSUB Research Group (Subsurface Geophysics and Geology). It is constituted by 21 members who had been collaborating regularly of the IGME former scientific-technic areas Geophysics and remote sensing (Área de Geofísica y Teledetección) and Subsurface geology and 3D geological modelling (Área de Geología del Subsuelo y Modelización Geológica 3D). Our main differentiating element is our extensive knowledge of geophysical and geological techniques, which allows us to characterize the subsoil in an optimal wa

IGME-CSIC has a highly relevant geological and geophysical database that includes a continuous digital geological cartography at 1:50000; 1:200000 and 1:1000000 scales and a fair amount of geophysical data: gravity, magnetic, well-logs in tiff and LAS format, seismic lines in tiff and SEG-Y format, borehole and petrophysical data, together with other geophysical and geological studies. Since the 2004, an important effort has been done to undertake 3D geological and geophysical modelling ranging from local studies (mineral exploration or CO2 storage sites) to regional geology for a better understanding of the subsurface structure and its geodynamic evolution as a base for other studies on natural hazards or mineral resources. These studies were ¿stand alone¿ and now IGME is designing a new strategy. It includes the available data and models harmonization (stratigraphy sequences, structural interpretations, faults distribution, seismic velocity models, spatial distribution of physical properties such as density and magnetic susceptibility, workflows, methodologies, evaluation of uncertainties, visualization, etc.) to comply with the FAIR (Findable, Accessible, Interoperable and Reusable) data standardization. In this way, the new 3D models will be easily integrated and available from the databases. This strategy includes collaboration with the Bureau de Recherches Géologiques et Minières of France (BRGM) and Laboratório Nacional de Energia e Geologia of Portugal (LNEG) in order to harmonize the Spanish geological data and models with their neighbours across national borders. The first step is being done in the framework of GeoERA projects. Plain-language Summary IGME-CSIC owns a large database that includes a highly valuable geological and geophysical data and geophysical studies containing the interpretation of some of the data of Spain (onshore and offshore) Since 2004 the authors of this work have been working in 3D geological and geophysical modelling that includes local (mineral exploration or CO2 storage sites) and regional studies. The goal is to improve our understanding of the subsurface structures and processes as a base for deepening our knowledge in how the natural hazards occur, how to improve the exploration for mineral resources, etc. These studies were made ad hoc within different projects and now IGME-CSIC is designing a workflow to harmonize these models in order to comply with the FAIR (Findable, Accessible, Interoperable and Reusable) data standardization so the models will be available to being used beyond the initial objectives that generated their creation. This strategy includes collaboration with other European institutions like the Bureau de Recherches Géologiques et Minières of France (BRGM) and Laboratório Nacional de Energia e Geologia of Portugal (LNEG) in order to harmonize the models across national borders. The first step is already being done in the framework of the GeoERA projects.

X Congreso Geológico de España, 5-7 Julio 2021, Vitoria - Gasteiz, La zona noroeste de Iberia reúne rasgos geológicos excepcionales relacionados con el desarrollo de un margen continental hiperextendido cerca de un punto triple y la posterior inversión tectónica parcial. Es una zona de gran interés para el estudio del papel de la herencia tectónica y la posterior inversión en márgenes continentales extensionales, pero hay un gran déficit de información. Todo esto sienta las bases del proyecto anfibio MARIBNO (PGC2018-095999-B-I00) donde a lo largo de 2021 y 2022 se adquirirán sísmica marina de reflexión multicanal 2D (~4000 km), sísmica de gran ángulo en 3 transectos tierra-mar (~600 km), batimetría multihaz, grav-mag y sísmica de alta resolución. Se complementará en tierra con adquisición de datos grav-mag y varias campañas de cartografía geológica. Los objetivos se centran en el estudio de la estructura cortical, el control tectónico ejercido por estructuras previas a las etapas alpinas y la cartografía y caracterización de los dominios corticales aunando criterios geológicos y geofísicos., Todo esto sienta las bases del proyecto anfibio MARIBNO (PGC2018-095999-B-I00) donde a lo largo de 2021 y 2022 se adquirirán sísmica marina de reflexión multicanal 2D (~4000 km), sísmica de gran ángulo en 3 transectos tierra-mar (~600 km), batimetría multihaz, grav-mag y sísmica de alta resolución.

During the Late Glacial–Early Holocene transition Southern Iberia has an extensive record of Palaeolithic coastal sites, wich have been preserved due thanks to the morphology of the continental shelf. This is was a period with rapid palaeoclimatic oscillations and changes in sea level. However, the sites show an apparent continuity in technology and subsistence trends, although human groups made increasingly intense use of marine resources. In this paper we will focus on the study of Mediterranean seal remains from the Vestibulo hall of Cueva de Nerja (Malaga, Spain), unit NV4, dated 12,990–11,360 cal. BP. The presence of these bones at the site are interpreted as direct exploitation of seals by humans, who processed different parts of the animal like the flesh, blubber and skin. These data allow us to assess the changing role of marine mammals in the regional Palaeolithic economy.

Deception Island (South Shetland Islands) is one of the most active volcanoes in Antarctica, with more than 15 explosive eruptive events registered over the past two centuries. Recent eruptions (1967, 1969 and 1970) and volcanic unrest episodes in 1992, 1999 and 2014–15 demonstrate that the occurrence of future volcanic activity is a valid and pressing concern for scientists, logistic personnel and tourists that are visiting or are working on or near the island. Over the last few decades, intense research activity has been carried out on Deception Island to decipher the origin and evolution of this very complex volcano. To that end, a solid integration of related scientific disciplines, such as tectonics, petrology, geochemistry, geophysics, geomorphology, remote sensing, glaciology, is required. A proper understanding of the island's evolution in the past, and its present state, is essential for improving the efficiency in interpreting monitoring data recorded during volcanic unrest periods and, hence, for future eruption forecasting. In this chapter, we briefly present Deception Island's most relevant tectonic, geomorphological, volcanological and magmatic features, as well as the results obtained from decades of monitoring the island's seismic activity and ground deformation.

The increasing demand for minerals and metals by society, together with the depletion of land resources, has generated a peaked interest in marine mineral exploitation. For a global commons such as the oceans, the International Seabed Authority is mandated under the United Nations Convention on the Law of the Sea to organize, regulate and control all mineral-related activities in the international seabed area for the benefit of mankind as a whole. Under the auspices of the International Seabed Authority (ISA), projects exploring seabed mineral resources in the seabed and ocean floor and subsoil thereof, beyond the limits of national jurisdiction, named ‘the Area’, began in 2001. From then to the present, more and more countries have become involved in such projects. The interest in seabed exploration lies in the extraction of Ni–Cu–Mn from polymetallic nodules, Co–Ni–Mn from ferromanganese crusts, and Cu–Zn–Au–Ag from polymetallic sulphides. Research developed in the last ten years has additionally demonstrated the existence of rare metals and rare earths as possible by-products of the extraction of the main metals of interest. The future exploitation of these metals has implications related to industrial and high-technology purposes, and is also closely linked to the development of renewable energies that enable us to face climate change, secure energy supplies, and promote sustainability and economic competitiveness. Currently, the Legal and Technical Commission of the ISA is finalizing the Regulations for the Exploitation of Mineral Resources in the Area, which will mark the starting signal of deep-sea mining.

9th SCAR Open Science Conference and XXXVI SCAR Meetings. Hobart, Tasmania, Australia. 31 July - 11 August 2020, [EN] The northern margin of the Antarctic Peninsula is affected by the most recent tectonic activity related to the last stage of the opening of the Drake Passage. The subduction along the South Shetland Trench of the Former Phoenix Plate, now belonging to the Antarctic Plate, contributes to the detachment of the continental South Shetland Block from the Antarctic Peninsula and the development of the Bransfield Basin. The underthrusting of the active transpressive sinistral Shackleton Fracture Zone below this continental block shaped the active triple junction that determined the NE tip of the South Shetland Trench and the uplift of Elephant Island. This geological context produced changes in tectonic regime along the NE Antarctic Peninsula, including transcurrence associated to the Shackleton Fracture Zone, compressive deformations with reverse faults and large open folds related to subduction in the northern part of South Shetland Block and Elephant Island and extensional processes in Bransfield back arc basin and the southern part of Elephant Island. The analysis of the recent structures from multichannel seismic profiles, detailed bathymetric data, seismicity including earthquake focal mechanisms and paleostresses determined from mesofault population analysis, improves the knowledge of the recent tectonic evolution of the triple junction and highlights implications on the latest palaeoceanographic evolution of the Drake Passage

patient satisfaction is a quality of care predictor that allows to identify specific areas of improvement. Frequently, parents are who provide this information when their children are too young or cannot communicate. The aim of the study was to determine parents' satisfaction with paediatric oncology care and its relationship with sociodemographic variables.a cross-sectional observational study was carried out. Parents whose children suffered from cancer and were treated in the oncology ward and oncology day hospital in Asturias were included. A questionnaire with sociodemographic variables and the Cuestionario de Calidad de Cuidados de Enfermería (CUCACE), that evaluates experience and satisfaction with care through two dimensions (range from 0 to 100), were used.24 parents agreed to particape. The average in experience dimension of CUCACE was 88,99 and 87,01 in satisfaction. All participants referred as positive the treat received at the units, however, 41,7% declared it should be enhanced. No relationship between satisfaction and sociodemographic variables were found.Parents of children with cancer demonstrated high satisfaction with care. Information and communication with medical staff need to be strengthened.

9th SCAR Open Science Conference and XXXVI SCAR Meetings. Hobart, Tasmania, Australia. 31 July - 11 August 2020, [EN] The separation of the Australian Plate with respect to the Antarctic Plate during the Cenozoic was the origin of the development of the Tasmania Passage. In order to better understand how the continental fragmentation and the plates drift occurred, it is important to establish the stress orientation and regime that have acted during the formation of this passage. With the aim to contribute to the knowledge of the tectonic evolution of the Tasmanian Passage, approximately 1000 faults distributed in 44 sites located in rocks of ages between the Cambrian and the Quaternary have been measured in Tasmania. The fault population analysis has been carried out using the methods of Etchecopar, y-R, Right Dihedral and Stress Inversion. The fault orientation analysis shows a predominant orientation ESE-WNW and secondary directions NE-SW, NW-SE and N-S. Considering the faults movement sense, 313 dextral, 194 sinistral, 422 normal and 62 reverse faults have been identified. Dextral faults show an ESE-WNW orientation. Sinistral faults have a predominant orientation N-S. The most of the dextral and sinistral fault planes dips are subvertical. Normal faults have a main NW-SE orientation and a NE-SW secondary direction with a modal dip value of 65°. Reverse faults have a predominant NE-SW direction with two modal dip values of 35° and 70° respectively. The σ1 orientation shows a dominant NW-SE direction. Moreover, another common stress regime is characterized by a preferentially NE-SW σ3 orientation (with σ1 vertical). The σy direction is dominantly NW-SE, although it shows a secondary mode with NE-SW orientation

The Middle (MP) and Early Upper Paleolithic (EUP) evidences of shellfish collection on the southern Iberian site of Bajondillo cave are presented and compared with Westernmost Mediterranean archaeological sites. The main feature is stasis for Mytilus galloprovincialis represents the dominant taxon during a ∼120kyr temporal sequence. The second feature is the decrease of the shellfishing signal when site distance to the coast increases. The data reveal that shellfish collection was practiced during Marine Isotopic Stage 4, a poorly documented stage in terms of aquatic adaptations. Striking is also that mollusc assemblages evidence an uninterrupted decreasing trend in terms of remains from the earliest to the latest levels, in particular when H. sapiens replaced H. neanderthalensis. Although taxa of secondary importance are too scarce to make reliable inferences, another difference between the MP and EUP collections is the substantial increase of infaunal bivalves in the latter cultural period. Warm and cold water mollusc records match temperature rises and drops although the scarcity of data do not allow one to proceed beyond qualitative statements. Likewise, the prevalence of fresh and brackish water mollusc hint at a permanent presence of freshwater around the site at all times. When compared with assemblages from the Alboran sea region (Westernmost Mediterranean Sea), the Bajondillo cave collections are remarkable for their abundance of mussels. Comparison between Bajondillo cave and Pinnacle Point reveal that infaunal bivalve abundances in the South African site are far higher than those recorded in the MP levels, though not those from the EUP. Whether this feature hints at subtle differences existing between the collection of shellfish by H. sapiens and H. neanderthalensis, reflects a behavioral convergence between the two hominine lineages or represents an inherited cognitive trait from a common ancestor is an issue in need of further analysis., The research of the Bajondillo faunal assemblages was allowed by the Consejería de Cultura of the Junta de Andalucía (Spain) (UPPH/49/06) to one of the authors (MCS). This research has been sponsored by Grants HAR2013-44269-P, HAR2014-55722-P, HAR2016-77789-P and HAR2017-88325-P from the Spanish Ministerio de Economía y Competitividad and 19438/PI/14. The paper constitutes a contribution of Research Group HUM-949 (University of Sevilla, Spain) and the ICArEHB (Universidade do Algarve, Portugal).
