    • Early spring subglacial discharge plumes fuel under-ice primary production at a Svalbard tidewater glacier 

      Vonnahme, Tobias; Persson, Emma; Dietrich, Ulrike; Hejdukova, Eva; Dybwad, Christine; Elster, Josef; Chierici, Melissa; Gradinger, Rolf (Peer reviewed; Journal article, 2021)
      Subglacial upwelling of nutrient-rich bottom water is known to sustain elevated summer primary production in tidewater-glacier-influenced fjord systems. However, the importance of subglacial upwelling during the early ...

    • Getz Ice Shelf melt enhanced by freshwater discharge from beneath the West Antarctic Ice Sheet 

      Wei, Wei; Blankenship, Donald D.; Greenbaum, Jamin S.; Gourmelen, Noel; Dow, Christine F.; Richter, Thomas G.; Greene, Chad A.; Young, Duncan A.; Lee, SangHoon; Kim, Tae-Wan; Lee, Won Sang; Assmann, Karen Margarete (Peer reviewed; Journal article, 2020)
      Antarctica's Getz Ice Shelf has been rapidly thinning in recent years, producing more meltwater than any other ice shelf in the world. The influx of fresh water is known to substantially influence ocean circulation and ...

    • Late summer sea ice segmentation with multi-polarisation SAR features in C- and X-band 

      Fors, Ane Schwenke; Brekke, Camilla; Doulgeris, Anthony Paul; Eltoft, Torbjørn; Renner, Angelika; Gerland, Sebastian (Journal article; Peer reviewed, 2016-02-17)
      In this study, we investigate the potential of sea ice segmentation by C- and X-band multi-polarisation synthetic aperture radar (SAR) features during late summer. Five high-resolution satellite SAR scenes were recorded ...

    • Methane cycling within sea ice: Results from drifting ice during late spring, north of Svalbard 

      Verdugo, Josefa; Damm, Ellen; Nikolopoulos, Anna (Peer reviewed; Journal article, 2021)
      Summer sea ice cover in the Arctic Ocean has declined sharply during the last decades, leading to changes in ice structures. The shift from thicker multi-year ice to thinner first-year ice changes the methane storage ...

    • Regional melt-pond fraction and albedo of thin Arctic first-year drift ice in late summer 

      Divine, Dmitry V; Granskog, Mats A.; Hudson, Stephen R.; Pedersen, Christina Alsvik; Karlsen, Tor Ivan; Divina, S.A.; Renner, Angelika; Gerland, Sebastian (Journal article; Peer reviewed, 2015-02-09)
      The paper presents a case study of the regional (≈150 km) morphological and optical properties of a relatively thin, 70–90 cm modal thickness, first-year Arctic sea ice pack in an advanced stage of melt. The study combines ...

    • Review Article: How does glacier discharge affect marine biogeochemistry and primary production in the Arctic? 

      Hopwood, Mark J.; Dustin, Carroll; Dunse, Thorben; Hodson, Andy; Holding, Johnna M; Iriarte, José L.; Ribeiro, Sofia; Achterberg, Eric P.; Cantoni, Carolina; Carlson, Daniel F.; Chierici, Melissa; Clarke, Jennifer S.; Cozzi, Stefano; Fransson, Agneta; Juul- Pedersen, Thomas; Winding, Mie S.; Meire, Lorenz (Peer reviewed; Journal article, 2020)
      Freshwater discharge from glaciers is increasing across the Arctic in response to anthropogenic climate change, which raises questions about the potential downstream effects in the marine environment. Whilst a combination ...

    • Signature of Arctic first-year ice melt pond fraction in X-band SAR imagery 

      Fors, Ane Schwenke; Divine, Dmitry V; Doulgeris, Anthony Paul; Renner, Angelika; Gerland, Sebastian (Peer reviewed; Journal article, 2017)
