Gridded bathymetry from multibeam echosounder EM120 data of the cruise M72/5 (2007)

Bathymetry based on data recorded during 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.

Gridded bathymetry from multibeam echosounder HS-DS2 data of the cruise M51/4 (2001)

Bathymetry based on data recorded during M51-4 between 13.12.2001 and 28.12.2001 in the Black Sea. The purpose of the present-study was to sample sediments and the water columns of the nw/sw Black Sea and the E Marmara Sea to study a) a high resolution sediment records of Holocene climate, b) biogeochemical associated with deep anaerobic methane oxidation, and c) element cycling in the stratified water column. Bathymetric data (hydrosweep + parasound) was primarily used to choose appropriate sites for coring of undisturbed sediments. Samples were taken for future analyses of abundance and activity of bacteria, geochemistry and dating.
