Processed underway Thermosalinograph (TSG) observations from the South Atlantic Meridional Overturning Circulation Basin-wide Array (SAMBA) on Algoa Voyage 295, September 2023

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected between 18 September 2023 and 08 October 2023 during the South Atlantic Meridional Overturning Circulation Basin-wide Array (SAMBA) cruise on the RS Algoa Voyage 295. 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).
