Ziel der Reise / Objectives of Cruise:
Geophysics, sedimentology and gas eruptions in the mud sediment belt off the Namibian coast.The cruise was designed to investigate the regional extension and the thickness of the mud sediment belt as well as the occurrence and structure of gas eruptions (craters) in the area between 22?S and 27?S. Sediment acoustic profiling, sediment coring and UW video observations were used to fulfil these tasks. In total about 1768 nm acoustic profiles were recorded and 42 sediment stations were sampled. Additionally, CTD profiles were carried out at all stations to measure the oxygen and H2S situation in the water column above the mud sediment. A ROV was used to obtain video-films from the sediment surface and to prove the settlement (colonization) of sulfur bacteria.
