    • Better synoptic and subseasonal sea ice thickness predictions are urgently required: a lesson learned from the YOPP data validation 

      Yang, Qinghua; Xiu, Yongwu; Luo, Hao; Wang, Jinfei; Landy, Jack Christopher; Bushuk, Mitchell; Wang, Yiguo; Liu, Jiping; Chen, Dake (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-20)
      In the context of global warming, Arctic sea ice has declined substantially during the satellite era (Kwok 2018). The retreating and thinning of Arctic sea ice provide opportunities for human activities in the Arctic, such as tourism, fisheries, shipping, natural resource exploitation, and wildlife management; however, new risks emerge. To ensure the safety and emergency management of human activities ...

    • Improvements in September Arctic Sea Ice Predictions Via Assimilation of Summer CryoSat-2 Sea Ice Thickness Observations 

      Zhang, Yong-Fei; Bushuk, Mitchell; Winton, Michael; Hurlin, Bill; Gregory, William; Landy, Jack Christopher; Jia, Liwei (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-15)
      Because of a spring predictability barrier, the seasonal forecast skill of Arctic summer sea ice is limited by the availability of melt-season sea ice thickness (SIT) observations. The first year-round SIT observations, retrieved from CryoSat-2 from 2011 to 2020, are assimilated into the GFDL ocean–sea ice model. The model's SIT anomaly field is brought into significantly better agreement with the ...

    • 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 ...
