Processed underway Thermosalinograph (TSG) observations from the Cape Canyon Exploration Cruise on Algoa Voyage 247, March 2018

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected between 05 March and 28 March 2018 during the Cape Canyon Exploration Cruise on the RS Algoa Voyage 247. 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).
