    • Improved Arctic Sea Ice Freeboard Retrieval From Satellite Altimetry Using Optimized Sea Surface Decorrelation Scales 

      Landy, Jack Christopher; Bouffard, Jerome; Wilson, Chris; Rynders, Stefanie; Aksenov, Yevgeny; Tsamados, Michel (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-18)
      A growing number of studies are concluding that the resilience of the Arctic sea ice cover in a warming climate is essentially controlled by its thickness. Satellite radar and laser altimeters have allowed us to routinely monitor sea ice thickness across most of the Arctic Ocean for several decades. However, a key uncertainty remaining in the sea ice thickness retrieval is the error on the sea surface ...

    • A year-round satellite sea-ice thickness record from CryoSat-2 

      Landy, Jack Christopher; Dawson, Geoffrey; Tsamados, Michel; Bushuk, Mitchell; Stroeve, Julienne C.; Howell, Stephen; Krumpen, Thomas; Babb, David G.; Komarov, Alexander S.; Heorton, Harold; Belter, H. Jakob; Aksenov, Yevgeny (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-14)
      Arctic sea ice is diminishing with climate warming at a rate unmatched for at least 1,000 years. As the receding ice pack raises commercial interest in the Arctic, it has become more variable and mobile, which increases safety risks to maritime users. Satellite observations of sea-ice thickness are currently unavailable during the crucial melt period from May to September, when they would be most ...
