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...
Commissioning of EIVA ScanFish on the Algoa Voyage 298, January 2024
In November 2018, the EIVA ScanFish III undulator and winch system was acquired, equipped with multiple physical and chemical sensors for real-time data collection. Initial commissioning and training trials were conducted aboard Algoa in December 2018 (ALG256). However, due to instrument damage, these trials were not fully completed. After repairs, additional commissioning trials were carried out during Algoa Voyage 298 in January 2024 to ensure full functionality and operational reliability...

Annual State of the Oceans reports
A series of reports on State of the Oceans around South Africa, produced by Branch Oceans and Coasts of South Africa’s Department of Environmental Affairs, was introduced in December 2006. The reports initially considered environmental parameters for the purposes of establishing general principles, such as annual cycles, and long-term trends, which may provide insight into the local effects of global warming and climate change. The reports were intended to provide an overview of marine...
