Raw underway Thermosalinograph (TSG) observations from the Algoa Voyage 269, October 2020

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). Here we present the 6-second resolution raw TSG data collected between 03 October 2020 and 16 October 2020, during Voyage 269 on the Algoa.
