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...

Wirewalker wave-powered profilers from three nearshore moorings in St Helena Bay, South Africa, Feb-Apr 2011

Concurrent nearshore measurements of temperature, salinity, and chlorophyll fluorescence from three moorings offshore of Elands Bay, within St Helena Bay, Southern Benguela, in water depths of ~22 m (mooring 3), ~50 m (mooring 2) and ~62 m (mooring 1). The data were originally presented in "Lucas, A. J., Pitcher, G. C., Probyn, T. A., & Kudela, R. M. (2014, March). The influence of diurnal winds on phytoplankton dynamics in a coastal upwelling system off south -western Africa.

Preprocessed 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 preliminary processed Seaglider data collected during GINA...
