| Abstract | 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. This dataset was processed using older standards which may not align with international best practices and the standards currently adhered to by the Department of Forestry, Fisheries and the Environment (DFFE). The Department is re-processing and replacing data to ensure everything has the same format and is of the same quality and datasets will be marked as obsoleted once that is done. As such the user assumes the entire risk related to the use of these data in its current state and format. DFFE disclaims all warranties of the data whether expressed or implied, including without limitation, any warranties of merchantability or fitness for a particular purpose. For any concerns regarding the data, the user may decide to liaise with the listed PIs who will share their insight on the data quality, where possible. It is also strongly recommended that the user liaises with the listed PIs regarding their proposed projects to mitigate against duplication of research efforts. |
| Methods | The vessel mounted 75kHz Teledyne RD Instruments ADCP, mounted in the vessel's scientific blister at a depth of 4m, was set to collect data for the duration of the voyage. Data was recorded using the Teledyne RDI VMDAS (version1.46) software. A blanking distance of 8m was used, with the bin size of 8m. The Short Term Averaged (STA) data, set to a 3 minute average, was processed and edited using the AquaVision ViSea DAS and ViSea DPS software. Data was then exported to text files. All velocity data is in m/s. |
