Processed CTD discrete observations from the student training and acoustic trials on the Africana Voyage 115, July 1993

Here we present processed Conductivity-Temperature-Depth (CTD) discrete data from the upcast collected between 13 July and 16 July 1993 during Voyage 115 on the FRS Africana, in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of Southern Africa. Neil Brown MK3 and MK4 CTD instruments were used to measure pressure, temperature and conductivity through the water column during research and monitoring cruises between 1983 and 2000.

Microplankton monitoring along the west coast of South Africa

Microplankton, comprising of both phyto- and zooplankton in the 20-200μm size range, are a diverse and ecologically important group. They form the foundation of the food web, are instrumental in carbon and nutrient cycling, generate at least 50% of global oxygen and facilitate energy flow to higher trophic levels. Although they are found in all oceans globally, their diversity and abundance is varied. Due to their high sensitivity and rapid response to changes in the environment, their...

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...

Deployment of acoustic listening moorings on the Algoa Voyage 297, January 2024

South Africa’s developing Oceans Economy Master Plan has increased the range, extent, and intensity of anthropogenic pressures on marine and coastal biodiversity. Activities such as offshore oil and gas exploration, marine transport, small harbour and infrastructure development, and marine tourism have led to elevated noise levels in the ocean and coastal environment. These increased noise levels may negatively impact marine biodiversity and ecosystem services, yet their effects are not yet...
