Data and buoy types

Our buoys are autonomous instruments that are either deployed right into open water within the Antarctic sea ice zone or ice-tethered right on and beneath the sea ice. The instruments rely on satellite communication (mostly through the Iridium network these days) to transmit their data back home. In addition to the scientific parameters, all buoys transmit their GPS position and the time of each measurement. Most buoys transmit their data also into the WMO's Global Telecommunication System (GTS). This allows the immediate use of the observations for Numerical Weather Predictions (NWP).
