SA Agulhas II Voyage 051 ... : Here we present the 6-second resolution raw Thermosalinograph (TSG) data collected between 16 April 2022 and 22 May 2022 on the Marion Island Relief Voyage was conducted on the SA Agulhas II Voyage 051. 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 2022 Marion Relief Voyage 051 offered the 10th 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 ...
