  • A long-term dataset of climatic mass balance, snow conditions, and runoff in Svalbard (1957-2018) 
    Van Pelt, Ward; Pohjola, Veijo; Pettersson, Rickard; Marchenko, Sergey A.; Kohler, Jack; Luks, Bartlomiej; Hagen, Jon Ove Methlie; Schuler, Thomas; Dunse, Thorben; Noel, Brice; Reijmer, Carleen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Abstract. The climate in Svalbard is undergoing amplified change compared to the global mean. This has major implications for runoff from glaciers and seasonal snow on land. We use a coupled energy balance–subsurface model, ...
  • Diagnosing the decline in climatic mass balance of glaciers in Svalbard over 1957-2014 
    Østby, Torbjørn Ims; Schuler, Thomas; Hagen, Jon Ove Methlie; Hock, Regine; Kohler, Jack; Reijmer, Carleen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Estimating the long-term mass balance of the high-Arctic Svalbard archipelago is difficult due to the incomplete geodetic and direct glaciological measurements, both in space and time. To close these gaps, we use a coupled ...
  • Glacier-surge mechanisms promoted by a hydro-thermodynamic feedback to summer melt 
    Dunse, Thorben; Schellenberger, Thomas; Hagen, Jon Ove Methlie; Kääb, Andreas; Schuler, Thomas Vikhamar; Reijmer, Carleen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Mass loss from glaciers and ice sheets currently accounts for two-thirds of the observed global sea-level rise and has accelerated since the 1990s, coincident with strong atmospheric warming in the polar regions. Here we ...
  • Low elevation of Svalbard glaciers drives high mass loss variability 
    Noël, Brice P.Y.; Jakobs, Constantijn L.; van Pelt, Ward; Lhermitte, Stef; Wouters, Bert; Kohler, Jack; Hagen, Jon Ove Methlie; Hagen, Jon Ove Methlie; Luks, Bartlomiej; Reijmer, Carleen; van de Berg, Willem Jan; van den Broeke, den (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Abstract Compared to other Arctic ice masses, Svalbard glaciers are low-elevated with flat interior accumulation areas, resulting in a marked peak in their current hypsometry (area-elevation distribution) at  ~450 m ...
  • Parameter uncertainty, refreezing and surface energy balance modelling at Austfonna ice cap, Svalbard, 2004-2008 
    Østby, Torbjørn; Schuler, Thomas; Hagen, Jon Ove Methlie; Hock, Regine; Reijmer, Carleen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    We apply a physically based coupled surface energy balance and snowpack model to a site close to the equilibrium line on Austfonna ice cap, Svalbard, over the 2004–08 melt seasons, to explain contributions to the energy ...
  • Surface speed and frontal ablation of Kronebreen and Kongsbreen, NW-Svalbard, from SAR offset tracking 
    Schellenberger, Thomas; Dunse, Thorben; Kääb, Andreas; Kohler, Jack; Reijmer, Carleen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    Kronebreen and Kongsbreen are among the fastest-flowing glaciers on Svalbard and, therefore, important contributors to the total dynamic mass loss from the archipelago. Here, we present a time series of area-wide surface ...
