• Arctic Observations Identify Phytoplankton Community Composition as Driver of Carbon Flux Attenuation 

      Wiedmann, Ingrid; Ceballos-Romero, E.; Villa-Alfageme, M.; Renner, Angelika; Dybwad, Christine; van der Jagt, Helga; Svensen, Camilla; Assmy, Philipp; Wiktor, Josef; Tatarek, Agnieszka; Różańska‐Pluta, M.; Iversen, Morten H. (Peer reviewed; Journal article, 2020)
      The attenuation coefficient b is one of the most common ways to describe how strong the carbon flux is attenuated throughout the water column. Therefore, b is an essential input variable in many carbon flux and climate ...
    • Eddy-driven recirculation of Atlantic Water in Fram Strait 

      Hattermann, Tore; Isachsen, Pål Erik; von Appen, Wilken-Jon; Albretsen, Jon; Sundfjord, Arild (Journal article; Peer reviewed, 2016)
      Eddy‐resolving regional ocean model results in conjunction with synthetic float trajectories and observations provide new insights into the recirculation of the Atlantic Water (AW) in Fram Strait that significantly impacts ...
    • Intermittent Reduction in Ocean Heat Transport Into the Getz Ice Shelf Cavity During Strong Wind Events 

      Steiger, Nadine; Darelius, Elin; Wåhlin, Anna; Assmann, Karen Margarete (Peer reviewed; Journal article, 2021)
      The flow of warm water toward the western Getz Ice Shelf along the Siple Trough, West Antarctica, is intermittently disrupted during short events of Winter Water deepening. Here we show, using mooring records, that these ...
    • Mechanisms underlying recent Arctic atlantification 

      Asbjørnsen, Helene; Årthun, Marius; Skagseth, Øystein; Eldevik, Tor (Peer reviewed; Journal article, 2020)
      Recent warming and reduced sea ice concentrations in the Atlantic sector of the Arctic Ocean are the main signatures of ongoing Arctic “Atlantification.” The mechanisms driving the warming trends are nevertheless still ...
    • Near-Surface Stratification Due to Ice Melt Biases Arctic Air-Sea CO2 Flux Estimates 

      Dong, Yuanxu; Yang, Mingxi; Bakker, Dorothee C. E.; Liss, Peter S.; Kitidis, Vassilis; Brown, Ian; Chierici, Melissa; Fransson, Agneta; Bell, Thomas G. (Peer reviewed; Journal article, 2021)
      Air-sea carbon dioxide (CO2) flux is generally estimated by the bulk method using upper ocean CO2 fugacity measurements. In the summertime Arctic, sea-ice melt results in stratification within the upper ocean (top ∼10 m), ...
    • Observational insights into chlorophyll distributions of subtropical South Indian Ocean eddies 

      Dufois, Francois; Hardman-Mountford, Nick J.; Fernandes, Michelle; Wojtasiewicz, Bozena; Shenoy, Damodar; Slawinski, Dirk; Gauns, Mangesh; Greenwood, Jim; Toresen, Reidar (Peer reviewed; Journal article, 2017)
    • Ocean heat transport into the Barents Sea: Distinct controls on the upward trend and interannual variability 

      Wang, Qiang; Wang, Xuezhu; Wekerle, Claudia; Danilov, Sergey; Jung, Thomas; Koldunov, Nikolay; Lind, Sigrid; Sein, Dmitry; Shu, Qi; Sidorenko, Dmitry (Journal article; Peer reviewed, 2019)
      Ocean heat transport through the Barents Sea Opening (BSO) has strong impacts on the Barents Sea ice extent and the climate. In this paper we quantified the contributions from different atmospheric forcing components to ...
    • Skillful prediction of Barents Sea ice cover 

      Onarheim, Ingrid Husøy; Eldevik, Tor; Årthun, Marius; Ingvaldsen, Randi; Smedsrud, Lars H. (Journal article; Peer reviewed, 2015-07-08)
      A main concern of present climate change is the Arctic sea ice cover. In wintertime, its observed variability is largely carried by the Barents Sea. Here we propose and evaluate a simple quantitative and prognostic framework ...
    • Tidally-forced lee waves drive turbulent mixing along the Arctic Ocean margins 

      Fer, Ilker; Koenig, Zoé Charlotte; Kozlov, Igor E.; Ostrowski, Marek; Rippeth, Tom; Padman, L.; Bosse, Anthony; Kolås, Eivind (Peer reviewed; Journal article, 2020)
      In the Arctic Ocean, limited measurements indicate that the strongest mixing below the atmospherically forced surface mixed layer occurs where tidal currents are strong. However, mechanisms of energy conversion from tides ...
    • Understanding differences in North Atlantic poleward ocean heat transport and its variability in global climate models 

      Madonna, Erica; Sandø, Anne Britt (Peer reviewed; Journal article, 2021)
      The ocean heat transport from the North Atlantic to the Barents Sea impacts the sea ice extent and the energy budget of the Arctic. The analyzed climate models from the fifth (CMIP5) and sixth Coupled Model Intercomparison ...
