Sea ice thickness retrieval algorithms based on in situ surface elevation and thickness values for application to altimetry

In situ measurements of sea ice thickness (I), snow depth (S), and snow freeboard (Fsn) from drilling profile lines from 15 cruises into the Southern Ocean, Antarctica, were analyzed. I was calculated from in situ Fsn and S using an isostatic approach. I was also directly estimated from Fsn as can b...
