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 Tuzla, 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.
