Abstract | Here we present the 6-second resolution raw Thermosalinograph (TSG) data collected between 16 July and 26 July 2018 during the SEAmester III and Agulhas System Climate Array (ASCA) cruise on the SA Agulhas II Voyage 033. A SeaBird SBE45 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 information. A temperature sensor close to the intake provides temperature measurements of the incoming water (T1). The temperature of the water inside the conductivity cell (T2) is used to accurately compute salinity (S) from the conductivity measurements (C). |
Methods | The SeaBird SBE45 Thermosalinograph (TSG) is used on the SA Agulhas II for the collection of underway near-surface temperature and conductivity measurements. The underway seawater is obtained from a depth of 5m below the surface and pumped through the TSG. Data is collected using the most recent SeaBird (SBE) SeaSave software and processed using the most recent SBE Data Processing software. The software was set to record data at 6 second intervals for the duration of the cruise, between 16 July and 26 July 2018. Data was collected in the southern part of the Benguela Current Large Marine Ecosystem (BCLME) region and in the Agulhas Current Large Marine Ecosystem (ACLME) region. |
