Raw underway Thermosalinograph (TSG) observations from the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on Algoa Voyage 235, February 2017

Here we present the 6-second resolution raw Thermosalinograph (TSG) data collected between 17 February and 24 February 2017 during the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the RS Algoa Voyage 235. 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).
