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...
