SC40 – SVP BRST: Sea surface temperature and depth measurement
The SC40 drifters are designed to monitor sea surface temperature and depth measurements. This product was developed within requirements of the Copernicus TRUSTED project.
Main features:
Very simple to use
In option: “holey socks drogue” and various length of line
Easy BT connection for parameters setting
Lithium and alkaline battery solutions
40cm diameter spherical buoy
Based on our WiSens technology
The data provided by the SC40 – SVP BRST will serve as calibration and validation of accurate satellite HRSST retrievals from the Copernicus Sentinel-3 SLSTR. The project will further assess the suitability of drifting buoys to provide Fiducial Reference Measurements.
