    • 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; Peer reviewed, 2019)
      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, forced ...
    • A predictive model for the spectral "bioalbedo" of snow

      Prediction of high latitude response to climate change is hampered by poor understanding of the role of nonlinear changes in ecosystem forcing and response. While the effects of nonlinear climate change are often delayed ...

      Bring, Arvid; Fedorova, Irina V.; Dibike, Yonas B.; Hinzman, Larry; Mård, Johanna; Mernild, Jacob Sebastian Haugaard; Prowse, Terry D.; Semenova, Olga M.; Stuefer, Svetlana L.; Woo, Ming-ko (Journal article; Peer reviewed, 2016)
      Terrestrial hydrology is central to the Arctic system and its freshwater circulation. Water transport and water constituents vary, however, across a very diverse geography. In this paper, which is a component of the Arctic ...
    • Assessing restoration success by predicting time to recovery- But by which metric? 

      Rydgren, Knut; Auestad, Inger; Halvorsen, Rune; Hamre, Liv Norunn; Jongejans, Eelke; Töpper, Joachim Paul; Sulavik, Jan (Peer reviewed; Journal article, 2019)

    • Assessing the Impact of Renewable Energy on Regional Sustainability—A Comparative Study of Sogn og Fjordane (Norway) and Okinawa (Japan) 

      Schwanitz, Valeria Jana; Wierling, August Hubert; Shah, Payal (Journal article; Peer reviewed, 2017)
      The drive to expand renewable energies is often in direct conflict with sustainable development goals. Thus, it is important that energy policies account for potential trade-offs. We assess the interlinkages between energy, ...
    • Between winter storm surges - Human occupation on a growing Mid-Holocene transgression maximum (Tapes) beach ridge at Longva, Western Norway 

      Bondevik, Stein; Lødøen, Trond; Tøssebro, Christine; Årskog, Hanne Bente; Hjelle, Kari Loe; Mehl, Ingvild Kristine (Journal article; Peer reviewed, 2019)
      Substantial amounts of archaeological material have been found intermixed with beach pebbles and cobbles on the Tapes beach ridge at Longva on the island Flemsøya/Skuløya in Western Norway. The artefacts show that the beach ...
    • Bunching up the background betters bias in species distribution models 

      Vollering, Julien Martin Marie; Halvorsen, Rune; Auestad, Inger; Rydgren, Knut (Journal article; Peer reviewed, 2019)
      Sets of presence records used to model species’ distributions typically consist of observations collected opportunistically rather than systematically. As a result, sampling probability is geographically uneven, which may ...
    • Community dynamics can modify the direction of simulated warming effects on crop yield 

      Gillespie, Mark; Jacometti, Marco; Tylianakis, Jason M.; Wratten, Steve D. (Journal article; Peer reviewed, 2018)
