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.

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

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

This data set consists of a bathymetric grid derived from multibeam bathymetry data from cruise JC071. The bathymetric grid was created by gridding cleaned raw multibeam data from JC071 at 1/64 arc-minute intervals. The data set covers an approximate one degree square with the minimum and maximum longitude and latitude co-ordinates: 17.016667W-16.216667W; 48.78333N-49.28333N. This is located in the Northeast Atlantic Ocean area. The data were collected from 7th-8th May 2012 using an EM120 Multibeam Echo-sounder. The cruise was part of the Porcupine Abyssal Plain (PAP): sustained ocean observation project. The bathymetry data were collected on an opportunistic basis during the cruise. The cruise was operated by the National Oceanography Centre (NOC), equipment operated by National Marine Facilities Sea Systems. The bathymetric grid was created by BODC for contributing to the EMODnet HRSM Project.

Multibeam data acquired in 2007 during the SVAIS cruise on board the R/VHespérides with a Simrad EM12 echo-sounder

Multibeam bathymetry of Haifa Bay. Description of processed data sources: the data come from the IOLR's R/V Etziona www.ocean.org) with a Kongsberg-Simrad EM1002 (90 kHz, 111 beams). The data is the property of the Israeli Government, Ministry of National Infrastructures, which was renamed to the Ministry of Energy and Water. The original data is classified. The navigation is all with real-time corrections and is <1 m. The appropriate oceanographic measurements were made with my AML CTD as well as a Valeport SV. The analysis was all done with CARIS HIPS/SIPS. The data include another survey in deeper water with an ELAC Nautik Gmbh. SeaBeam 3050 50 kHz system, a year ago aboard the R/V Mediterranean Explorer (www.ecoocean.com) . It covered some 7,000 sq. km. from depths of ~500 to 1600 m.
