Bottom samples collected by CNR-ISMAR (Bologna) in the South Adriatic Sea located from -250 m to -900 m depth. The dataset consists of grabs, dredges, box cores, ROVs and lander. It was collected from 2006to 2014 during the following oceanographic cruises: ALTRO, ARCADIA, BARCA2007, COCOMAP13, COCOMAP14, CROMA, MEMA12, SASSI08, SETE2006.

Desctription of Mediteranean Sea surface circulation (0-200m) starting from litterature review

Digital Elevation Model (DEM) from 1280 to 2120 water depth at 40 meters resolution. Bathymetric surface collected during the oceanographic cruise JAMMEGAIA22 on board of the R/V GAIA BLU by CNR.

Acoustic backscatter data collected through the use of a Reson SeaBat 7125 high-resolution multibeam system

High-resolution DTM with 2.5 m grid cell size produced from the bathymetric survey carried out aboard the M/B ‘Risal’ in April 2015, in order to map the whole margin of Lampedusa Island, in the 2–50 m depth range.

Bathymetry of Linosa Island (10 × 10 m cell grid size) collected by the Institute for Coastal Marine Environment (IAMC, now ISMAR, Institute of Marine Sciences) of the National Research Council (CNR) of Naples (Italy) during two oceanographic surveys, ‘Linosa 2016’ (17–29 August 2016) and ‘BioGeoLin 2017’ (8–20 September 2017), onboard the R/V Minerva UNO

Acoustic dataset collected in the frame of the research project ABBaCO (Environmental Restoration of the Bagnoli-Coroglio National Site of Interest). The Project was aimed to support planning actions for the restoration of marine habitats of the Bagnoli-Coroglio area, characterized by the presence of a large industrial site from 1910 until the 1990s. Backscatter data were collected as "snippet data" by means of a Teledyne Reson SeaBat 7125 multibeam echosounder and processed using FMGeocoder Toolbox (FMGT) in Fledermaus 7.6 version.

High-resolution DTM (1 m × cell) of Lampione collected by the Institute for Coastal Marine Environment (IAMC, now ISMAR, Institute of Marine Sciences) of the National Research Council (CNR) of Naples (Italy) during the oceanographic survey ‘BioGeoLin 2017’ (8–20 September 2017), onboard the R/V Minerva UNO

Acoustic backscatter data collected through the use of a Reson SeaBat 7125 high-resolution multibeam system

Digital Elevation Model (DEM) of the Ave estuary in Portugal collected by Deltares in the framework of the MAELSTROM Project
