Processed underway Thermosalinograph (TSG) observations from the Integrated Ecosystem Programme: Southern Benguela (IEP: SB) on the Algoa Voyage 277, November 2021

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected between 15 November and 23 November 2021 during the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the RS Algoa Voyage 277. 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). This is a long-term monitoring line conducted off the coast of Kleinsee, Namaqualand, Elands/St Helena Bay and Scarborough on the west coast of South Africa. The IEP:SB in 2013...
