Ice buoys

An ice buoy (red) on sea ice.

FMI uses GPS-Iridium ice drift buoys (MetOcean) to measure sea ice drift in the Baltic Sea. A buoy tracks its coordinates, air pressure and sea surface temperuture (when in open water) every 3 hrs.  Every winter,  4-6 buoys are deployed on the sea ice at the Baltic Sea for validation of SAR imagery based sea ice drift and for operational sea ice monitoring.

Additionally, few buoys have also been deployed in the Arctic (e.g. two buoys to the central Arctic by German R/V Polarstern in August 2014).
