Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected between 16 April 2023 and 18 May 2023 during the Marion Island Relief Voyage on the SA Agulhas II Voyage 057. 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).
