Raw underway Thermosalinograph (TSG) observations from SA Agulhas II Voyage 024, April 2017
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...

The first objective of this cruise was to establish, by means of surveying and trawling between 200m and 500m water depths, the feasibility of extending the hake biomass surveys to the South Coast. The area 20 E to 25 E, from 75m to 200m water depths, has already been covered during biomass surveys by Japanese research vessels, accompanied on each occasion by one of the Institute's scientists. The feasibility of trawling shallower than 200m in this region, albeit with heavy gear, has thus...
