Processed underway Thermosalinograph (TSG) observations from SA Agulhas II Voyage 059, September 2023

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected between 16 September 2023 and 17 October 2023 on the SA Agulhas II Voyage 059. 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).
