Illustration of the wave spectra acquired by a subset of 5 buoys from the CIRFA_UIT deployment. The buoys were initially deployed on sea ice in late April to early May 2022. The 4 buoys at the top ultimately ended up in water, as visible by the transitions (highlighted by the thick red bars) from spectra where high frequencies are filtered out, to spectra where significant high frequency energy is present. The 5th buoy never ended up in the open water, as it drifted into an ice-covered fjord on the East coast of Greenland. Transmission took place until mid December 2022 for the 4 buoys that survived transition to open water conditions.
