Abstract This is processed Conductivity, Temperature, Depth (CTD) data from the Southern Ocean Seasonal Cycle Experiment (SOSCEx) III Winter Cruise on the SA Agulhas II Voyage 016, 22 July to 15 August, 2015. The third Southern Ocean Seasonal Cycle Experiment (SOSCEx) III is a high-resolution full seasonal cycle experiment using integrated observational and modeling platforms. A novel aspect of SOSCEx III is the integrated multi-platform approach, which aims to explore new questions about the climate sensitivity of carbon and ecosystem dynamics in the Southern Ocean and how these processes are parameterized in models. This winter 2015 cruise can be divided into two primary tracks, the GoodHope line, between Cape Town and the ice edge along the Greenwich Meridian, and the South Atlantic Meridional Overturning Circulation Basin-wide Array (SAMBA) line, between Cape Town and the Greenwich Meridian, at 34.5 degrees South longitude. 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.
