| contents | Multibeam echosounder (MBES) data recorded during RV METEOR cruise M143 between 12.12.2017 and 22.12.2017 in the Black Sea. The expedition aimed to investigate possible areas of seafloor depressions and slope failure along the shallow part of the Black Sea margin in the Danube Delta by bathymetry mapping and water column observation. A second emphasis is on collecting 38 kHz echosounder data in combination with multibeam water column images for quantification of gas emissions. CI Citation: Paul Wintersteller (seafloor-imaging@marum.de) as responsible party for bathymetry raw data ingest and approval. Description of data sources: During the cruise RV METEOR cruise M143 the hull-mounted Kongsberg EM710 with a nominal sounding frequency of 70-100 kHz was utilized. 256 beams with an acoustical footprint of 1°(Tx)/1°(Rx) are formed for each ping. For further information consult: http://epic.awi.de/26726/1/Kon2007b.pdf. The use of the high-density equidistant and the dual-swath mode of the EM710 resulted in up to 800 soundings per ping. The EM710 was recording constantly within the Romanian border, with the aim to map slumping and sliding zones, and morphologic surveys. The data quality was generally good, though affected by unstable weather conditions. Soft underground and shallow water depth resulted also in a strong nadir artefact, the so called 'Eric's Horn' type artefacts, which were later removed manually during the post processing phase.
