Abstract	This is processed Conductivity, Temperature, Depth (CTD) data from SANAE, S.A Agulhas II voyage 018 from 05 December 2015 to10 February 2016. The South African National Antarctic Expedition (SANAE) is an annual cruise undertaken by the Department of Environmental Affairs (DEA) to change the overwintering teams in Antarctica and to replenish the supplies at the SANAE IV Research base. This voyage was to deliver the SANAE 55 team to the island and return with the SANAE 54 team. The cruise was undertaken between with full scientific complement. 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 CTD raw data was converted to scientific units using SBEDataProcessing software (ver 7.26.7.114). The following modules (SBEDataProcessing) were then run on the converted data using the recommended default values: Align CTD, Filter, Loop Edit and Cell Thermal Mass. The data was then split into the up cast and the down cast. The down cast data was then bin averaged on pressure, every 1db.
