Raw TSG data from the Walters Shoal Cruise on Algoa Voyage 207, May 2014

This is raw Thermosalinograph (TSG) data collected on the Walters Shoal Cruise on Algoa Voyage 207, 15 May to 11 June 2014. The purpose of this cruise was to survey the oceanographic conditions and plankton distributions around Walter Shoal seamount, from beyond the 1000m contour line across the plateau.

Raw TSG data from the St Helena Bay Monitoring Line (SHBML) on the Algoa Voyage 195, March 2013

This is raw Thermosalinograph (TSG) data from the St Helena Bay Monitoring Line, which now falls under the Integrated Ecosystem Programme: Southern Benguela, on the Algoa Voyage 196, 4 to 8 March, 2013.The St Helena Bay Monitoring Line was initiated as a BENEFIT-driven project on "shipboard monitoring" which linked with similar lines run in Namibia and Angola. The aims are to obtain seasonal and interannual information on the hydrology and productivity of the area. Data on harmful algal blooms, low oxygen water and intrusions of Agulhas Bank water along the west coast will also be collected. A long-term, multi-decadel time-series (from 1951 onward) of information already exists for this important region and has continued in the form of the IEP:SB to detect long-term changes in the hydrology and the plankton, which are important for the detection of regime shifts.

Carbonate chemistry time-series from discrete sampling at thirteen sites in Algoa Bay, South Africa, 2018 - 2020

Coastal monthly carbonate chemistry data and other associated physico-chemical parameters from Algoa Bay, on the temperate south coast of South Africa. Eight offshore and five inshore sites were sampled. Temperature, salinity and dissolved oxygen were measured at each offshore site, and temperature was measured at each inshore site. At each offshore and inshore site, a single sea water sample was collected at the surface for later analysis of pH and total alkalinity (TA) in the laboratory. Remaining parameters of the carbonate system (including pCO2) were calculated in the software program CO2SYS (Lewis and Wallace, 1998) using pH and TA as input parameters. Temperature, salinity, silicate and phosphate concentrations were included in the calculations as supplemental data which may influence carbonate speciation.

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).
