MSM13/3 raw data of EM120 multibeam echosounder (bathymetry, beam time series & water column)

Between 25.10. and 18.11.2009, Multibeam data based on the KONGSBERG Simrad EM120 were acquired during RV Maria S. Merian cruise MSM13/3.The investigation of diversity and community distribution of chemosynthetic ecosystems related to fluid escape structures at the eastern and central provinces of the Nile fan (Eastern Mediterranean Sea) was the main research target. Additionally element transport rates and fluid export related to these fluid seeps was further explored. This cruise was in corporation with the DIWOOD program. Therefore wood, which was deployed in 2006/2007, was recovered to investigate the influence of wood degradation on ecosystems. To collect gas/fluid and sediment samples, the ROV QUEST4000 (MARUM) was utilized. During the cruise hydroacoustic systems (Multibeam and Parasound) were recorded to generate high-resolution maps of the research areas as well as to identify and to quantify seepage structures. […]
