Raw underway Thermosalinograph (TSG) observations from the Algoa Voyage 257, January 2019

Here we present the 6-second resolution raw Thermosalinograph (TSG) data collected between 08 January 2019 and 25 January 2019 on the RS Algoa Voyage 257. 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).
