    • A Comparison of Arctic Ocean Sea Ice Export Between Nares Strait and the Canadian Arctic Archipelago 

      Howell, S.E.L.; Babb, D.G.; Landy, Jack Christopher; Moore, G.W.K.; Montpetit, B.; Brady, M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-13)
      Nares Strait and the channels of the Canadian Arctic Archipelago (CAA) act as conduits for sea ice export from the Arctic Ocean but have never been directly compared. Here, we perform such a comparison for both the sea ice area and volume fluxes from October 2016 to December 2021. Nares Strait provided the largest average seasonal (October through September) ice area flux of 95 ± 8 × 10<sup>3</sup> ...

    • The Stepwise Reduction of Multiyear Sea Ice Area in the Arctic Ocean Since 1980 

      Babb, D.G.; Galley, R.J.; Kirillov, S.; Landy, Jack Christopher; Howell, S.E.L.; Stroeve, J.C.; Meier, W.; Ehn, J.K.; Barber, D.G. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-28)
      The loss of multiyear sea ice (MYI) in the Arctic Ocean is a significant change that affects all facets of the Arctic environment. Using a Lagrangian ice age product, we examine MYI loss and quantify the annual MYI area budget from 1980 to 2021 as the balance of export, melt, and replenishment. Overall, MYI area declined at 72,500 km<sup>2</sup> /yr; however, a majority of the loss occurred ...
