Analysed nutrient data from the Gough Island Relief Voyage on the SA Agulhas II 068, September 2025

Dissolved inorganic macronutrients nitrate (NO3), nitrite (NO2), silicate (PO4) and phosphate (PO4) in the upper waters of the ocean. The availability of these macronutrients limits and regulates the production of organic matter during photosynthesis. Therefore, phytoplankton uptake of the macronutrients plays a necessary role concerning biogeochemical cycling of carbon around Gough Island and the Southern Ocean. Here we present macronutrients data collected along the upstream, near island and downstream of the Gough Island (39.8 °S, 9.5 °W and 40.8 °S, 10.4 °W) during the yearly logistical voyage of the Department of Forestry, Fisheries and the Environment (DFFE) from the 15 September to 15 October 2025. We sampled 10 stations which were grouped into three categories: upstream stations, near island stations and downstream stations. Seawater samples were analysed for macronutrients concentrations within three months of collection, with detection limits of 0.03 μM for nitrate +...

Raw data collected by Seaglider SG573 off Cape Town for CTD calibration (SeaTrials 2)

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). This dataset includes all data collected by Seaglider SG573 during the first GINA deployment in 2018. The Seaglider 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 data collected by Seaglider SG573...

Short-term observations of currents and sub-surface temperatures on the continental shelf off Port St Johns, along the east coast of South Africa

Between 2013 and 2014, a short-term mooring deployment was conducted to determine the oceanographic characteristics and variability off Port St Johns, along the east coast of South Africa. One mooring (PJ) was deployed, at a depth of 95m, between July 2013 and September 2014. This mooring measured currents, as well as sub-surface bottom temperatures on the continental shelf off Port St Johns on the east coast of South Africa.

Short-term observations of hourly bottom temperatures on the continental shelf off Port St Johns, along the east coast of South Africa (December 2013 - September 2014)

Between 2013 and 2014, a short-term mooring deployment was conducted to determine the oceanographic characteristics and variability of Port St Johns, along the east coast of South Africa. One mooring (PJ) was deployed, at a depth of 90m, between July 2013 and September 2014. This mooring measured currents, as well as sub-surface bottom temperatures on the continental shelf off Port St Johns on the east coast of South Africa. Here we present processed hourly bottom temperatures (85 m) from an ADCP at location PJ (31.73°S; 29.51°E) on the continental shelf off Port St Johns, between December 2013 and September 2014.
