Processed SADCP data from Leg 1 of the African Coelacanth Ecosystem Programme (ACEP) II on the Algoa Voyage 177, July 2010

The Algoa sailed from Durban on 16 July 2010 to conduct a hydrographic survey of the Natal Bight as part of the winter African Coelacanth Ecosystem Programme (ACEP) II. A total of 16 shore-normal transects were occupied between Scottburgh and St. Lucia. The aim of the synoptic survey was to determine the nutrient sources of the Natal Bight ecosystem, and to characterise the focus sites across the Bight. This dataset was processed using older standards which may not align with international...

Raw underway Thermosalinograph (TSG) observations from RS Algoa Voyage 252, August 2018

Here we present the 6-second resolution raw Thermosalinograph (TSG) data collected, between 20 August and 28 August 2018, during voyage 252 on the RS Algoa. A SeaBird SBE45 Thermosalinograph (TSG) is used to opportunistically collect underway near-surface temperature and conductivity measurements during research and monitoring cruises. Water is continuously pumped to the TSG from an intake located in the hull of the vessel, and the observations are continuously interfaced with navigational...

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...
