“…The measurement of freeboard heights of Arctic sea‐ice by radar altimetry from the ERS satellites was first described by Peacock et al [1998]. Results have so far not been obtained in the central Arctic Ocean due to orbit limitations (ERS coverage limited to 81°N).…”

[1] We present a new method to measure ice thickness of polar sea-ice freeboard heights, using airborne laser altimetry combined with a precise geoid model, giving estimates of thickness of ice through isostatic equilibrium assumptions. In the paper we analyze a number of flights from the Polar Sea off Northern Greenland, and estimate accuracies of the estimated freeboard values to be at a 13 cm level, corresponding to about 1 m in absolute thickness.
