Raw Echo Sounder data from the Marion Island Relief Voyage on the SA Agulhas II Voyage 007, April 2013

This is raw Echo Sounder 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, from the sea floor, through water...

Raw Seaglider data collected during GINA 2017 by Seaglider SG574

The Gliders IN the Agulhas (GINA) project is a multi-institutional effort to implement sustained glider observations around South Africa’s coastline to enhance existing regional networks and complement larger international observations systems such as the Ocean Gliders Boundary Ocean Observing Network (BOON). Ocean gliders are robotic platforms operated and piloted from land. The Seaglider during GINA was set-up to vertically profile the water column between depths of 0 and 1000m. Measurements collected included conductivity (salinity), temperature, depth (CTD), dissolved oxygen, chlorophyll-a fluorescence (proxy for phytoplankton concentration), Photosynthetically Active Radiation (PAR) and two wavelengths of optical back-scattering by particles, Bb(470) and Bb(700) (proxies for particle concentration). In addition, information collected from the Seaglider was used to derive surface and depth averaged currents. This is raw Seaglider data collected during GINA 2017 by Seaglider SG574.

SDS data from the South Coast Mooring Cruise on the Algoa Voyage 208, July 2014

This is Scientific Data System (SDS) data collected on the South Coast Mooring Cruise on the Algoa Voyage 208, 9 to 24 July 2014. The South Coast Mooring Cruise had two scientific objectives: (1) Service, maintain and extend the in situ operational oceanography network currently deployed around South Africa and (2) to investigate the dynamics of the Port St Johns eddy and biological implications. Between 1988 and 2011, environmental and plankton sampling was conducted every summer along the South Coast during the annual pelagic spawner biomass surveys. Data collected during these cruises has provided valuable insight into environmental change in this region. There has been significant decline in copepod biomass on both the western and central Agulhas Bank over the past two decades, as well as a decline in the proportion of the large dominant species Calanus agulhensis, resulting in a shift towards a smaller copepod-dominated community. These changes are thought to have been largely...

SDS data from the South Coast Moorings and Monitoring Lines Cruise on the Algoa Voyage 213, December 2014

This is Scientific Data System (SDS) data from the South Coast Moorings and Monitoring Lines Cruise on Algoa Voyage 213 on 1 to 19 December, 2014. Between 1988 and 2011, environmental and plankton sampling was conducted every summer along the South Coast during the annual pelagic spawner biomass surveys. Data collected during these cruises has provided valuable insight into environmental change in this region. There has been significant decline in copepod biomass on both the western and central Agulhas Bank over the past two decades, as well as a decline in the proportion of the large dominant species Calanus agulhensis, resulting in a shift towards a smaller copepod-dominated community. These changes are thought to have been largely driven by predation by planktivorous fish, which have increased in biomass since the mid-1990s, but increasing sea temperatures have also played a role. It is vital that we continue to monitor the environment and plankton community in key areas off the...

Raw CTD data from Port St Johns Conductivity Temperature Depth (CTD) and Bathymetry Survey on Algoa Voyage 198, May 2013

Raw Conductivity, Temperature, Depth (CTD) data from Port St Johns Conductivity, Temperature, Depth (CTD) and Bathymetry Survey on Algoa Voyage 198, 8 May - 13 May, 2013. This cruise has two scientific objectives: (1) to investigate the dynamics of the Port St. Johns eddy and biological implications and (2) to investigate the existence of mesoscale eddies in the Agulhas Current. In the case of the former, Oceans & Coasts was asked to provide input to the recent spate of shark attacks off Port St. Johns. Very little is known about the oceanography except that Roberts et al (2010) discovered during a cruise a lee-trapped cyclonic eddy off Port St. Johns that caused substantial slope upwelling. The cold upwelled water is nutrient-rich and appears to provide a biological pump to the local ecosystem. This cruise will deploy an ADCP in a depth of approximately 80 m to determine the frequency of appearance of this eddy coupled with Conductivity, Temperature, Depth (CTD) lines to measure...

Short-term observations of currents and sub-surface temperatures on the continental shelf and slope off Port Edward, South Africa

Between 2005 and 2015, multiple short-term studies were conducted to determine the characteristics of moorings deployed in a region heavily influenced by the strong Agulhas Current, and to examine circulation patterns across the continental shelf and slope off Port Edward, along the east coast of South Africa.
