BUSCADOR RECOLECTA

SVAIS Cruise (29HE20070802) carried out on the Research Vessel Hespérides in 2007, The aim of the cruise is to reconstruct the changes that occurred on the seabed southwest of the Svalbard Islands (Norway) since the beginning of the glacial conditions, three million years ago, up to the present time. Thus, a better knowledge of the natural evolution of glaciers during past times, warmer than today, will help us a better understanding of current and future climate changes. 8,600 km2 of the seafloor surveyed for bathymetry and subbottom profiling , 516 km of single channel seismic reflection profiles 31 meters of sediment recovered (6 cores)

The Euro-Mediterranean Submarine landSlide database (EMSS21) displays information collected from both the literature and geophysical records. Data from the literature is collected from georeferenced map figures, from which the outline of the landslide deposit and the landslide scar have been digitized. Most information such as age, volume, typology, inferred trigger mechanism and relationship to fluid flow features and metadata is extracted from the relevant article. Area of the deposit and landslide runout is determined from the digitized polygons and polylines, volume (if not available) is determined from area and mean thickness. If the latter is not available, the volume is determined from the Area-Volume relationship for landslides where volume has already been determined. When the data originates directly from geophysical records the outline and scars have been determined from geomorphological interpretation of swath bathymetric maps and interpretation of submarine landslides on a variety of seismic records. In such instances, age information originates from a variety of methods presenting a wide range of accuracies, from radiometric dating to well-seismic correlation as well as ages inferred from mean sedimentation rates. In many instances, landslides identified in the literature are dated with an age epoch only., Disclaimer: The EMSS21 is open to later additions and improvements. For these reasons and due to its intrinsic nature, the EMSS21 cannot be guaranteed to be complete, accurate and updated in any part, and will be subjected to successive revisions. Although the Institut de Ciències del Mar of CSIC makes every effort to supply the best available information, no warranty, expressed or implied, is provided as to the accuracy and reliability of all the data supplied in the EMSS21. Users are cautioned to consider carefully the nature of the data and information before using it for decisions that concern personal or public safety. Conclusions drawn from the EMSS21, or actions undertaken on the basis of its contents, are the sole responsibility of the user., The Euro-Mediterranean Submarine landSlide database (EMSS21) is a catalogue of submarine landslides of the Mediterranean Sea and the European continental margins of the Atlantic and Arctic Oceans. The catalogue is compiled from data available in the literature as well as information collected from geophysical data and not published in the scientific literature. The data set includes polygons and polylines for the landslide deposits and landslide scars as well as information relative to age, volume, area, runout, thickness, typology, scar elevation, geological setting, depth, slope, inferred trigger mechanism, relationship to fluid flow features as well as the relevant metadata. The catalogue includes submarine landslides that span the Miocene to Present day. Nevertheless a clear bias exist towards submarine landslides of younger age, particularly for the smaller events, as these events are difficult to map/identify on lower resolution geophysical data sets typically collected in deep-water and large sub-surface depths. The catalogue aims to offer improved understanding of mass-wasting processes, the potentially resulting tsunamis and derived geohazard.
