Abstract	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 best practices and the standards currently adhered to by the Department of Forestry, Fisheries and the Environment (DFFE). The Department is re-processing and replacing data to ensure everything has the same format and is of the same quality and datasets will be marked as obsoleted once that is done. As such the user assumes the entire risk related to the use of these data in its current state and format. DFFE disclaims all warranties of the data whether expressed or implied, including without limitation, any warranties of merchantability or fitness for a particular purpose. For any concerns regarding the data, the user may decide to liaise with the listed PIs who will share their insight on the data quality, where possible. It is also strongly recommended that the user liaises with the listed PIs regarding their proposed projects to mitigate against duplication of research efforts.
Methods	The vessel mounted 75kHz Teledyne RD Instruments ADCP , mounted in the vessel's scientific blister at a depth of 4m,was set to collect data for the duration of the voyage. Data was recorded using the Teledyne RDI VMDAS (version1.46) software. A blanking distance of 8m was used, with the bin size of 8m.The Short Term Averaged (STA) data, set to a 3 minute average, was processed and edited using the Aqua Vision ViSea DAS and ViSea DPS software. Data was then exported to text files. All velocity data is in m/s.
