Instrument: Thermosalinograph
A thermosalinograph (TSG) is used to obtain a continuous record of sea surface temperature and salinity. On many research vessels the TSG is integrated into the ship's underway seawater sampling system and reported with the underway or alongtrack data.
Hull-mounted sea surface temperature sensor: STS SEG-14 (Range -2 to +35 degrees C; Accuracy + or - 0.1 deg C). Sensor located in the machine shop compartment, starboard side, between the hull and insulation. Ouput connected to the main MET acquisition computer.
