TSG (ThermoSalinoGraph)
The thermosalinometer gives the temperature and salinity of water pumped
under the surface, accurate to about a hundredth.
It is composed of a cell with electrodes which determine sea water's
conductivity. Thermistors measure the water temperature in the cell and near the
hull.
The thermosalinometer is an automated Sea Surface Temperature and
Salinity measurement system making measurement onboard the ship using a water
intake. A conductivity cell and a thermistor cell provide conductivity and
temperature measurements. Salinity is derived from conductivity and temperature.

IRD |
A conductivity cell and a thermistor cell provide conductivity and
temperature measurements. Salinity is derived from conductivity and temperature.
The ship’s position is given by a GPS. A computer usually located on the
bridge makes the data acquisition, data processing, recording, and controls the
real-time transmission of the data through satellite.
The data aquisition system includes :
-
- a Sea-Bird thermosalinograph
(SBE-21 model) (Bellevue, Wa, USA)
- a portable computer
- a 4 serial channels multiplex box
- an electric sea water pump to feed
up the thermosalinograph
