West Coast Physical Oceanography on the Africana Voyage 019, May 1984

Africana Cruise 019 lasted from May 7 to May 17th 1984 and undertook several scientific tasks. The first part of the cruise was mostly devoted to bathymetric and geophysical (continuous reflection seismic) surveys in the region of the Cape Canyon of SW Cape. These surveys were the responsibility of personnel from the Marine Geoscience Unit of the University of Cape Town, and were done as part of a collaborative project with officers of the Sea Fisheries Research Institute who have an interest in the physiography of the Canyon and adjacent areas. The project received nominal financial support during 1984 from the SANCOR CSP Marine Sedimentology Programme.

Processed CTD data from the Marion Island Relief Voyage on the SA Agulhas II Voyage 007, April 2013

This is processed Conductivity, Temperature, Depth (CTD) data from the Marion Island Relief Voyage on the SA Agulhas II Voyage 007, 10 April to 16 May 2013.The 2013 Marion Relief Voyage 007 on board South Africa’s new polar research and supply vessel, the SA Agulhas II, afforded yet another opportunity to conduct multi-institutional (DEA, DAFF, UCT, SAEON, Rhodes University) and multi-disciplinary ship-based oceanographic research that focused on links and interactions between air and sea, ocean physics, biogeochemistry, plankton and benthic communities and island-based top predators. The overall aim is to establish 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 the Southern Ocean Observation System (SOOS), CCAMLR, ACAP, etc., by documenting ship-board observations in the oceanic environment around the Prince Edward Islands in a holistic manner,...

Raw SDS data from the Winter Shakedown Cruise on SA Agulhas II Voyage 003, July 2012

This is raw Scientific Data System (SDS) data from the Winter Shakedown Cruise on SA Agulhas II, Voyage 003, 9 July to 6 August, 2012. The cruise started in Cape Town and went down to the GoodHope Line then up to the Prince Edward Islands, on to Port Elizabeth and then back to Cape Town. After the arrival of SA Agulhas II back to South Africa, an inaugural Southern Ocean cruise was undertaken, which included a multidisciplinary program to measure oceanographic and biological parameters that characterise the state of the Southern Ocean in the region of interest to South Africa, along with the ecosystem properties of the major gyres, frontal systems and shelf and plateau areas. Additionally, land-based research on marine mammals and seabirds was undertaken at South Africa’s Prince Edward Islands (PEIs). The aim of the cruise was to test the research vessels capability and its equipment and to increase our understanding with regard to the influences of oceanographic conditions...

Processed underway Thermosalinograph (TSG) observations from the South Atlantic Meridional Overturning Circulation Basin-wide Array (SAMBA) Monitoring Line cruise on the Algoa Voyage 253, October 2018

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected between 01 October and 16 October 2018 during the South Atlantic Meridional Overturning Circulation Basin-wide Array (SAMBA) Monitoring Line cruise on the RS Algoa Voyage 253. A SeaBird SBE45 TSG is used to opportunistically collect underway near-surface temperature and conductivity measurements during research and monitoring cruises. Water is continuously pumped to the TSG from an intake located in the hull of the vessel, and the observations are continuously interfaced with navigational information. A temperature sensor close to the intake provides temperature measurements of the incoming water (T1). The temperature of the water inside the conductivity cell (T2) is used to accurately compute salinity (S) from the conductivity measurements (C). The cruise operated from Slangkop, off Cape Town, westwards to 15° E, in the South Atlantic Ocean along the SAMBA transect. The objectives of the...
