This dataset was collected during a survey within GEOSED Project by means of the MBES system Reson SeaBat8111 in the area named Punta Licosa in the Tyrrhenian Sea, Central Mediterranean. The dataset was acquired on the continental shelf in the depth range 10-150 meters.The Multibeam has 101 beams 1°x1° and an operational frequency of 100 kHz. A LandStar 12 channel DGPS system was used for ship positioning and a motion sensor TSS-DMS02-05 was used to provide corrections for attitude data. A Sound Velocity Sensor was installed near the transducers thus providing realtime sound speed for beam steering. A sound velocity profiler Reson SVP20 was lowered through the water column every 6–8 h to get the velocity profile required for the depth computation. The bathymetric data were processed using the PDS2000 software. Data de-spiking was carried out without the application of automatic filters in order to preserve data accuracy and resolution

Source data for the EMODNet DTM for the Belgium Coastal Waters is compiled by the Vlaamse Hydrografie (http://www.afdelingkust.be/en/bathymetric-database) at a resolution of 1/512 arc minute. The data set covers the waters along the Belgian coast.

The Nord Stream 2 dataset covers a narrow zone of the pipeline. The pupose is reconnaissance surveys.

This composite Digital Terrain Model (cDTM) is a high resolution bathymetry dataset that covers CASCADES-I, CASCADES-II, COSTEM-1, COSTEM-2, COSTEM-3, COSTEM-4, FORMED-2, FORMED-4 and FORMED-6 cruises. Multibeam data acquired in 2008, 2009, 2010, 2011, 2013, 2014 and 2015 on board the R/V Sarmiento de Gamboa and the R/V García del Cid with an Atlas Hydrosweep DS-3 and an Elac Seabeam 1050D echo-sounder.

Bathymetric data resulting from hydrographic surveys for cartographic purposes and/or port management. Surveys carried out in accordance with the IHO S-44 standard.
