  • Increasing carbon inventory of the intermediate layers of the Arctic Ocean 

    Ericson, Ylva; Ulfsbo, Adam; van Heuven, Steven; Kattner, Gerhard; Anderson, Leif G. (AGU, 2014)
    Concentrations of dissolved inorganic carbon (DIC), total alkalinity (TA), nutrients, and oxygen in subsurface waters of the central Arctic Ocean have been investigated for conceivable time trends over the last two ...

  • Drivers of the marine CO2 system in the High Arctic - from the deep basins to the shallow fjords 

    Ericson, Ylva (The University of Bergen, 2019-02-20)
    The High Arctic is largely undersampled in terms of marine CO2 system data due to the cold dark season and often an extensive sea ice cover. The current understanding of the Arctic carbon cycle is thus vulnerable to both ...

  • Impact of Arctic sea ice variations on winter temperature anomalies in northern hemispheric land areas 

    Köenigk, Torben; Gao, Yongqi; Gastineau, Guillaume; Keenlyside, Noel; Nakamura, Tetsu; Ogawa, Fumiaki; Orsolini, Yvan; Semenov, Vladimir A.; Suo, Lingling; Tian, Tian; Wang, Tao; Wettstein, Justin; Yang, Shuting (Springer, 2018-07-30)
    Coordinated numerical ensemble experiments with six different state-of-the-art atmosphere models have been used in order to evaluate the respective impact of the observed Arctic sea ice and sea surface temperature (SST) ...

  • Continued warming, salinification and oxygenation of the Greenland Sea gyre 

    Lauvset, Siv Kari; Brakstad, Ailin Dale; Våge, Kjetil; Olsen, Are; Jeansson, Emil; Mork, Kjell Arne (Informa UK Limited, 2018-06-18)
    The Greenland Sea gyre is one of the few areas where the water column is ventilated through open ocean convection. This process brings both anthropogenic carbon and oxygen from the atmosphere and surface ocean into the ...

  • Arctic Ocean CO2 uptake: An improved multiyear estimate of the air-sea CO2 flux incorporating chlorophyll a concentrations 

    Yasunaka, Sayaka; Siswanto, Eko; Olsen, Are; Hoppema, Mario; Watanabe, Eiji; Fransson, Agneta Ingrid; Chierici, Melissa; Murata, Akihiko; Lauvset, Siv Kari; Wanninkhof, Rik; Takahashi, Taro; Kosugi, Naohiro; Omar, Abdirahman; van Heuven, Steven; Mathis, Jeremy T. (EGU, 2018-03-22)
    We estimated monthly air–sea CO2 fluxes in the Arctic Ocean and its adjacent seas north of 60∘ N from 1997 to 2014. This was done by mapping partial pressure of CO2 in the surface water (pCO2w) using a self-organizing map ...

  • On freshwater and the density-driven circulation in the northern seas 

    Lambert, Erwin (The University of Bergen, 2017-11-29)
    The Arctic Ocean and the Nordic Seas are freshening, in part due to anthropogenic climate change. Within the northern seas, seawater density is in part dominated by temperature, and in part by salinity. This reflects on ...
