Multibeam echosounder (MBES) data recorded during RV METEOR cruise M72-5 between 14.05.2007 and 06.06.2007 in the Black Sea. This cruise focused on the biogeochemical and microbiological processes around the oxic/anoxic interface of the chemocline in the water column and in shelf sediments as well as in the TOC-rich sediments of the deep Black Sea basins. A further important goal was to investigate the regional palaeo-climate on the basis of sedimentological analyses of early Holocene and previously deposited interglacial and limnic sediments. CI Citation: Paul Wintersteller (seafloor-imaging@marum.de) as responsible party for bathymetry raw data ingest and approval. Description of the data source: During the RV METEOR cruise M72-5 the Kongsberg EM120 multibeam echosounder with a nominal sounding frequency of 12 kHz was utilized. 191 beams are formed for each ping with a 1°(Tx)/2°(Rx) footprint while the seafloor is detected using amplitude and phase information for each beam sounding. For further information consult https://epic.awi.de/26725/1/Kon2007a.pdf. As the EM120 system was unstable due to some internal system failure it could not be used during some of the M72-5 cruise time. The vessel's speed was 8 kn during surveys.
