South African records of azooxanthellate Scleractinians (i.e., stony cold-water corals)

South African azooxanthellate Scleractinia have not been comprehensively reviewed since Boshoff’s 1980 study, despite decades of additional sampling and scattered regional reports. This study updates the country’s coral species inventory by examining museum collections, particularly from the Iziko South African Museum and the Smithsonian Institution, alongside historical imagery, recent survey data, and existing literature. The results increase the known diversity from 77 to 108 species across eleven families, including 28 new national records, three new species, and one newly described genus.

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 +...

Long-term observations of hourly bottom temperatures at Sodwana Bay, South Africa

Here we present a collection of raw and processed temperatures from Underwater Temperature Recorders (UTRs) located off Sodwana Bay, South Africa. At selected sites around Southern Africa, UTRs have been used to obtain long-term records of bottom temperatures in the nearshore environment, at depths ranging from 2m to 34m.
