Description
Summary:A SeaBird SBE45 Thermosalinograph (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). Here we present the 10-second resolution raw TSG data collected, between 12 December 2019 and 27 February 2020, during Voyage 041 on the SA Agulhas II. ... : 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 7m below the surface and pumped through the TSG. Data is collected using the most recent SeaBird (SBE) SeaSave software. The software was set to record data at 10 second intervals for the duration of the cruise, between 12 December 2019 and 27 February 2020. Data was collected in the southern part of the Benguela Current Large Marine Ecosystem (BCLME) region, on the west and south coasts of South Africa, in the eastern part of the South Atlantic Ocean, and in the Southern Ocean. ...
