HF radar sea surface velocity off the South African coast and processed with HYDDOA v.2

This dataset contains sea surface velocity measurements from six High-Frequency (HF) radar stations located along the South African coast, between Mossel Bay in the Western Cape and Port Elizabeth in the Eastern Cape. The HYDDOA v.2 framework is used to process the data, producing high-resolution, quality-controlled velocity fields that are appropriate for research and operational oceanography. The end date of the dataset is dynamic and subject to frequent updates since new data is constantly being retrieved.

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 +...
