The DTM is produced with Kongsberg multibeam echosounder survey, acquired in 2015 by Marine Research Ltd. The resolution is 1/256 arc-minutes (~7.2m). It is located south of Constanta Port, Romania, on the coastal region of the Black Sea. Depths are referenced to the Mean Sea Level and the coordinates are expressed into the WGS84 reference frame.

It is located in Costinesti, Romania, on the coastal region of the Black Sea. Depths are referenced to the Mean Sea Level and the coordinates are expressed into the WGS84 reference frame.

The DTM is produced with Kongsberg multibeam echosounder survey, acquired in 2015 by Marine Research Ltd. The resolution is 1/256 arc-minutes (~7.2m). It is located north of Mangalia Port, Romania, on the coastal region of the Black Sea. Depths are referenced to the Mean Sea Level and the coordinates are expressed into the WGS84 reference frame.

The DTM is produced with Kongsberg multibeam echosounder survey, acquired in March 2020 by Marine Research Ltd. The resolution is 1/256 arc-minutes (~7.2m). It is located at Mangalia Harbour, Romania, on the coastal region of the Black Sea. Depths are referenced to the Local Sea Level - Marea Neagra 1975 and the coordinates are expressed into the WGS84 reference frame.

387 points were surveyed with a SP80 DGPS by Maxime Paschal as part of the La Rochelle Zero Carbon Territory (LRTZC) project on 26/05/23. At each point, the type of vegetation was specified.

The DTM is produced from the S201502800-1 multibeam echosounder survey, acquired in 2015. The resolution is 1/1024 arc-minutes (~4m). It is located in front of Dunkirk (France) with depths from -16.4m to -43.3m. Depths are referenced to the Lowest Astronomical Tide and the coordinates are expressed into the WGS84 reference frame. Data and metadata associated to the survey are available on the website http://diffusion.shom.fr/pro/lots-bathy.html. The DTM is not to be used for navigation.

A total of 210 points in 2024 (28 May, 18 april, 13 September, 19 September, and 25 October) and 195 points in 2025 (8 April, 18 and 29 April, 3 June, 17 June, and 4 July) were surveyed with an SP80 DGPS as part of the ESA Coastal Blue Carbon project. Additionally, 174 and 160 points obtained from photointerpretation of multispectral drone orthomosaics from 19 September 2024 and 18 September 2025, respectively, were recorded. At each point, the vegetation type was specified.
