Ziel der Reise / Objectives of Cruise:
SONNE cruise SO283 is not a classical research cruise based on a single research project, but aims to continue ongoing mooring programs of different projects in the South Atlantic, i.e. to recover existing moorings or to re-deploy them - hence Mooring Rescue. Mooring Rescue compensates for the research cruises with RV Meteor and RV Maria S. Merian that were cancelled in 2020 and 2021 due to the Corona pandemic. The goal is to recover existing moorings in time before they have to be considered technically lost. In addition to the loss of instruments and equipment, there was also a threat of loss of invaluable data that could not be replaced. All core objectives of the cruise were achieved. As part of the DFG program TRR181, two moorings were deployed in the open South Atlantic in approximately 5000 m water depth between April 9 and 11, flanked by Pressure Inverted Echo Sounders (PIES). For the TRAFFIC project (Trophic TRAnsfer eFFICiency in the Benguela Current), the sediment trap moorings were recovered in the Bengula upwelling area and re-deployed at four locations (two South Africa, two Namibia) between April 15 and April 23. In the northern Benguela area off Namibia, three IOW moorings were recovered and one was re-deployed between April 22 and April 28. As part of the BANINO project (Benguela Ni?os: physical processes and long term variability), an oceanographic mooring system was successfully recovered and re-deployed off the coast of Angola (May 03 and 04). The remaining time in the working areas was used for oceanographic, biogeochemical and biological work as well as for underway measurements. Furthermore, five ARGO floats were deployed. In total, scientific work was successfully carried out at 101 stations.
