Purpose
Abstract The SO259 expedition targeted the German license area for polymetallic sulfides in the Indian Ocean. The cruise focused on the detailed bathymetric, geophysical and geological exploration for active vents and inactive sulfide fields in the clusters #10, #11 and #12. The wider license area, the clusters #1, #3#, #4, #5 and #7 and the clusters of interest were also sampled for environmental, i.e., (paleo) oceanographic, sedimentary and faunal base line studies by gravity coring and multicoring, water sampling, and sediment trap moorings. Though multibeam has been recorded during the cruise, it was not a major focus and the responsible party provided no acquisition information.
