    • The Coldest and Densest Overflow Branch Into the North Atlantic is Stable in Transport, But Warming 

      Larsen, Karin Margretha Húsgarð; Hansen, Bogi; Hátún, Egil Hjálmar; Johansen, Guðrið Eriksdóttir; Østerhus, Svein; Olsen, Steffen Malskær (Peer reviewed; Journal article, 2024)
      The overflow of cold water through the Faroe Bank Channel (FBC) is the densest water crossing the Greenland-Scotland Ridge and the densest source for the Atlantic Meridional Overturning Circulation (AMOC). Here, we show ...

    • FRIS Revisited in 2018: On the Circulation and Water Masses at the Filchner and Ronne Ice Shelves in the Southern Weddell Sea 

      Janout, Markus A.; Hellmer, Hartmut H.; Hattermann, Tore; Huhn, Oliver; Sültenfuß, Jürgen; Østerhus, Svein; Stulic, Lukrecia; Ryan, Svenja; Schröder, Michael; Kanzow, Torsten (Peer reviewed; Journal article, 2021)
      The Filchner-Ronne Ice Shelf (FRIS) is characterized by moderate basal melt rates due to the near-freezing waters that dominate the wide southern Weddell Sea continental shelf. We revisited the region in austral summer ...

    • The Iceland-Faroe warm-water flow towards the Arctic estimated from satellite altimetry and in situ observations 

      Hansen, Bogi; Larsen, Karin Margretha Húsgarð; Hátún, Egil Hjálmar; Olsen, Steffen M.; Gierisch, Andrea M. U.; Østerhus, Svein; Ólafsdóttir, Sædis (Peer reviewed; Journal article, 2023)
      The inflow of warm and saline Atlantic water to the Arctic Mediterranean (Nordic Seas and Arctic Ocean) between Iceland and the Faroes (IF inflow) is the strongest Atlantic inflow branch in terms of volume transport and ...

    • Observed interannual changes beneath Filchner-Ronne Ice Shelf linked to large-scale atmospheric circulation 

      Hattermann, Tore; Nicholls, Keith W.; Hellmer, Hartmut H.; Davis, Peter E. D.; Janout, Markus A.; Østerhus, Svein; Schlosser, Elisabeth; Rohardt, Gerd; Kanzow, Torsten (Peer reviewed; Journal article, 2021)
      Floating ice shelves are the Achilles’ heel of the Antarctic Ice Sheet. They limit Antarctica’s contribution to global sea level rise, yet they can be rapidly melted from beneath by a warming ocean. At Filchner-Ronne Ice ...

    • Slowdown of Antarctic Bottom Water export driven by climatic wind and sea-ice changes 

      Zhou, Shenjie; Meijers, Andrew J.S.; Meredith, Michael P.; Abrahamsen, E. Povl; Holland, Paul R.; Silvano, Alessandro; Sallee, Jean-Baptiste; Østerhus, Svein (Peer reviewed; Journal article, 2023)
      Antarctic Bottom Water (AABW) is pivotal for oceanic heat and carbon sequestrations on multidecadal to millennial timescales. The Weddell Sea contributes nearly a half of global AABW through Weddell Sea Deep Water and ...

    • Southern ocean carbon and heat impact on climate 

      Sallée, J.B.; Abrahamsen, E.P.; Allaigre, C.; Auger, M.; Ayres, H.; Badhe, R.; Boutin, J.; Brearley, J.A.; De Lavergne, Lavergne; Ten Doeschate, Doeschate; Droste, E.S.; Du Plessis, Plessis; Ferreira, D.; Giddy, I.S.; Gülk, B.; Gruber, N.; Hague, M.; Hoppema, M.; Josey, S.A.; Kanzow, T.; Kimmritz, Madlen; Lindeman, M.R.; Llanillo, P.J.; Lucas, N.S.; Madec, G.; Marshall, D.P.; Meijers, A.J.S.; Meredith, M.P.; Mohrmann, M.; Monteiro, P.M.S.; Mosneron Dupin, Dupin; Naeck, K.; Narayanan, A.; Naveira Garabato, Garabato; Nicholson, S.-A.; Novellino, A.; Ödalen, M.; Østerhus, Svein; Park, W.; Patmore, R.D.; Piedagnel, E.; Roquet, F.; Rosenthal, H.S.; Roy, T.; Saurabh, R.; Silvy, Y.; Spira, T.; Steiger, Nadine; Styles, A.F.; Swart, S.; Vogt, L.; Ward, B.; Zhou, S. (Peer reviewed; Journal article, 2023)
      The Southern Ocean greatly contributes to the regulation of the global climate by controlling important heat and carbon exchanges between the atmosphere and the ocean. Rates of climate change on decadal timescales are ...
