    A complete Holocene lake sediment ancient DNA record reveals long-standing high Arctic plant diversity hotspot in northern Svalbard 
    Voldstad, Linn H.; Alsos, Inger G.; Farnsworth, Wesley; Heintzman, Peter D.; Håkansson, Lena; Kjellman, Sofia E.; Rouillard, Alexandra; Schomacker, Anders; Eidesen, Pernille B. (Elsevier BV, 2020-04-15)
    Arctic hotspots, local areas of high biodiversity, are potential key sites for conservation of Arctic biodiversity. However, there is a need for improved understanding of their long-term resilience. The Arctic hotspot of Ringhorndalen has the highest ...

    Geomorphology and surficial geology of the Femmilsjøen area, northern Spitsbergen 
    Allaart, Lis; Schomacker, Anders; Håkansson, Lena M.; Farnsworth, Wesley Randall; Brynjólfsson, Skafti; Grumstad, Andreas; Kjellman, Sofia E. (2021-06-01)
    Climate change is amplified in the Arctic, and establishing baseline data for its current character is important. Here we present a map of the geomorphology of the Femmilsjøen area, Spitsbergen, northern Svalbard. The regional physiography is characterised ...

    Glacial history of the Åsgardfonna Ice Cap, NE Spitsbergen, since the last glaciation 
    Allaart, Lis; Schomacker, Anders; Larsen, Nicolaj K.; Nørmark, Egon; Rydningen, Tom Arne; Farnsworth, Wesley Randall; Retelle, Michael; Brynjólfsson, Skafti; Forwick, Matthias; Kjellman, Sofia E. (2021-01-01)
    The response of glaciers and ice caps to past climate change provides important insight into how they will react to ongoing and future global warming. In Svalbard, the Holocene glacial history has been studied for many cirque and valley glaciers. ...

    Holocene precipitation seasonality in northern Svalbard: Influence of sea ice and regional ocean surface conditions 
    Kjellman, Sofia E.; Schomacker, Anders; Thomas, Elizabeth K.; Håkansson, Lena; Duboscq, Sandrine; Cluett, Allison A.; Farnsworth, Wesley; Allaart, Lis; Cowling, Owen C.; McKay, Nicholas P.; Brynjólfsson, Skafti; Ingolfsson, Olafur (Elsevier BV, 2020-07-15)
    Arctic precipitation is predicted to increase in the coming century, due to a combination of enhanced northward atmospheric moisture transport and local surface evaporation from ice-free seas. However, large model uncertainties, limited long-term ...

    Postglacial relative sea level change and glacier activity in the early and late Holocene: Wahlenbergfjorden, Nordaustlandet, Svalbard 
    Schomacker, Anders; Farnsworth, Wesley; Ingolfsson, Olafur; Allaart, Lis; Håkansson, Lena; Retelle, Michael; Siggaard-Andersen, Marie-Louise; Korsgaard, Niels Jákup; Rouillard, Alexandra; Kjellman, Sofia E. (Springer Science and Business Media LLC, 2019-05-01)
    Sediment cores from Kløverbladvatna, a threshold lake in Wahlenbergfjorden, Nordaustlandet, Svalbard were used to reconstruct Holocene glacier fluctuations. Meltwater from Etonbreen spills over a threshold to the lake, only when the glacier is significantly ...
