The coastal heights data combines two datasets: the land-sea mask of the gridded EMODnet bathymetry and the height of high-water (HAT) relative to chart datum (LAT) as computed with the GTSM tide model. Near the coast a diffusion scheme is applied to make the heights consistent with the land-sea mask. Finally, only grid cells that are classified as sea, but neighbor a land cell are selected. The main assumption in this approach is that the height of the topography near the coastline is close to the high-water mark. The main purpose of this dataset is to improve extrapolation towards the coast. In many areas around Europe there is a (small) gap between the point closest to the coast for which a survey is available and the coastline. In this way interpolation from coarser background data is avoided.

Gridded multibeam data acquired during scientific surveys and transits of French research vessels from 1992 to 2017 off the French Caribbean Islands.

DTM derived from a hydrographic survey (EMEPC LH1) performed within the scope of the Portuguese Continental Shelf Extension Project (UNCLOS). The data made available to the Emodnet project was sampled from the survey data with an aproximate 250m sampling interval, in N-S and E-W directions.

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

This dataset was collected during a survey within "Parchi Marini" Project of CNR aimed to seafloor characterization in potential protected marine areas. Bathymetric data were collected by means of the MBES system Simrad EM3000 that was pole-mounted on a 30 meters long vessel. The MBES has 127 beams and an operational frequency of 300 kHz. A 12 channel DGPS system was used for ship positioning and a motion sensor TSS-DMS02-05 was used to provide corrections for attitude data
