Algoa Voyage 278 ... : Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected between 06 December and 19 December 2021 during the Benguela Air-Sea CO2 and Heat Flux Experiment cruise on the Algoa Voyage 278. 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). The cruise operated on the West Coast of South Africa at a fixed location between Station 4 and 5 of the St. Helena Bay monitoring line (SHBML) with the ship's bow into the wind. The objectives of the ...
