NOSS salinity sensor
The thermodynamic properes of seawater, such as density and enthalpy, are now correctly expressed as functions of Absolute Salinity rather than being functions of the conductivity of seawater. Spatial variations of the properties composition of seawater mean that Absolute Salinity is not simply proportional to Practical Salinity.
NOSS sensor is an unique underwater sensor for in situ refractive index measurement and capable to detect salinity anomalies of seawater. NOSS sensor has been designed for use even in harsh environments, down to 2000 meters.
