SA Agulhas II Voyage 045 ... : Here we present the 6-second resolution raw Thermosalinograph (TSG) data collected between 09 April 2021 and 12 May 2021 during the 2021 Marion Relief Voyage on the SA Agulhas II Voyage 045. 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). The 2021 Marion Relief Voyage 045 offered the 9th opportunity to conduct multi-disciplinary, ship-based oceanographic research on board the SA Agulhas II en-route to, from, and around, the sub-Antarctic Prince Edward Islands. ...
