A network of wave, sea-ice drift, and temperature observations
During the Svalbard Marginal Ice Zone 2025 Campaign we deployed 21 OpenMetBuoys, in the beginning of May 2025 in the Marginal Ice Zone (MIZ) north west of Svalbard. with help of the Norwegian Coast Guard (KV Svalbard). The observed variables include air and surface temperature, sea-ice drift, and wave energy spectra. The drift of the buoys and the observed temperatures and wave energy spectra can be monitored here.
The OpenMetBuoy is an open-source drifter originally developed to measure waves in sea-ice. An extended version is used in the SvalMIZ 2025 experiment to measure wave, drifter-position, and temperatures. Two-hourly significant wave height, hourly temperature (1m height, snow-ice interface, one-meter in sea ice), infrared snow skin surface temperature and sea-ice drift are transmitted via Iridium in real-time. The buoys were deployed on sea-ice.
