This is processed Shipboard Acoustic Doppler Current Profiler (SADCP) data from the Marion Island Relief Voyage on SA Agulhas II Voyage 011, 14 April to 14 May 2014. The 2014 Marion Relief Voyage on board South Africa’s polar research and supply vessel MV SA Agulhas II, offered another opportunity to conduct multi-disciplinary ship-based oceanographic research focusing on links and interactions between air and sea, ocean physics, chemistry, biogeochemistry and biology. The overall aim was to continue contributing to the establishment of an oceanographic observation and monitoring system directed by South African research institutions in support of South Africa’s needs – and where possible, the global requirements of GOOS, SOOS, CCAMLR, ACAP, etc. With the recent declaration in April 2013 of the Prince Edward Islands (PEIs) as South Africa’s first offshore Marine Protected Area (MPA), the outcomes of this cruise will further contribute toward an integrated view and a better understanding of the functioning of the combined island/marine PEI ecosystem.
