    • 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 ...

    • Aerodynamic roughness length of crevassed tidewater glaciers from UAV mapping 

      Dachauer, Armin; Hann, Richard; Hodson, Andrew (Peer reviewed; Journal article, 2021)
      The aerodynamic roughness length (z_0) is an important parameter in the bulk approach for calculating turbulent fluxes and their contribution to ice melt. However, z_0 estimates for heavily crevassed tidewater glaciers are ...

    • Geochemical signatures of pingo ice and its origin in Grøndalen, West Spitsbergen 

      Demidov, Nikita; Wetterich, Sebastian; Verkulich, Sergey; Ekaykin, Alexey; Meyer, Hanno; Anisimov, Mikhail; Schirrmeister, Lutz; Demidov, Vasily; Hodson, Andrew (Peer reviewed; Journal article, 2019)
      Pingos are common features in permafrost regions that form by subsurface massive-ice aggradation and create hill-like landforms. Pingos on Spitsbergen have been previously studied to explore their structure, formation ...

    • Glacier algae accelerate melt rates on the south-western Greenland Ice Sheet 

      Cook, Joseph M.; Tedstone, Andrew J.; Williamson, Christopher; McCutcheon, Jenine; Hodson, Andrew J.; Dayal, Archana; Skiles, McKenzie; Hofer, Stefan; Bryant, Robert; McAree, Owen; McGonigle, Andrew; Ryan, Jonathan; Anesio, Alexandre M.; Irvine-Fynn, Tristram D.L.; Hubbard, Alun Lloyd; Hanna, Edward; Flanner, Mark; Mayanna, Sathish; Benning, Liane G.; van As, Dirk; Yallop, Marian; McQuaid, James B.; Gribbin, Thomas; Tranter, Martyn (Peer reviewed; Journal article, 2020)
      Melting of the Greenland Ice Sheet (GrIS) is the largest single contributor to eustatic sea level and is amplified by the growth of pigmented algae on the ice surface, which increases solar radiation absorption. This ...

    • GrSMBMIP: intercomparison of the modelled 1980-2012 surface mass balance over the Greenland Ice Sheet 

      Fettweis, Xavier; Hofer, Stefan; Krebs-Kanzow, Uta; Amory, Charles; Aoki, Teruo; Berends, Constantijn J.; Born, Andreas; Box, Jason E.; Delhasse, Alison; Fujita, Koji; Gierz, Paul; Goelzer, Heiko; Hanna, Edward; Hashimoto, Akihiro; Huybrechts, Philippe; Kapsch, Marie-Luise; King, Michaela D.; Kittel, Christoph; Lang, Charlotte; Langen, Peter L.; Lenaerts, Jan T.M.; Liston, Glen E.; Lohmann, Gerrit; Mernild, Jacob Sebastian Haugaard; Mikolajewicz, Uwe; Modali, Kameswarrao; Mottram, Ruth H.; Niwano, Masashi; Noël, Brice; Ryan, Jonathan C.; Smith, Amy; Streffing, Jan; Tedesco, Marco; Van de Berg, Willem Jan; Van den Broeke, Michiel; Van de Wal, Rodecrick S.; Von Kampenhout, Leo; Wilton, David; Wouters, Bert; Ziemen, Florian; Zolles, Tobias (Peer reviewed; Journal article, 2020)
      Observations and models agree that the Greenland Ice Sheet (GrIS) surface mass balance (SMB) has decreased since the end of the 1990s due to an increase in meltwater runoff and that this trend will accelerate in the future. ...

    • Holocene thinning of Darwin and Hatherton glaciers, Antarctica, and implications for grounding-line retreat in the Ross Sea 

      Hillebrand, T. R.; Stone, John O.; Koutnik, M. R.; King, Courtney; Conway, Howard; Hall, Brenda; Nichols, Keir; Goehring, B; Gillespie, Mette Kusk (Peer reviewed; Journal article, 2021)
      Chronologies of glacier deposits in the Transantarctic Mountains provide important constraints on grounding-line retreat during the last deglaciation in the Ross Sea. However, between Beardmore Glacier and Ross Island – a ...

    • Numerical modelling of permafrost spring discharge and open-system pingo formation induced by basal permafrost aggradation 

      Hornum, Mikkel Toft; Hodson, Andrew; Jessen, Søren; Bense, Victor; Senger, Kim (Journal article; Peer reviewed, 2020)
      In the high Arctic valley of Adventdalen, Svalbard, sub-permafrost groundwater feeds several pingo springs distributed along the valley axis. The driving mechanism for groundwater discharge and associated pingo formation ...

    • Pressure and inertia sensing drifters for glacial hydrology flow path measurements 

      Alexander, Andreas; Kruusmaa, Maarja; Tuhtan, Jeffrey; Hodson, Andrew; Schuler, Thomas; Kääb, Andreas (Peer reviewed; Journal article, 2020)
      Glacial hydrology plays an important role in the control of glacier dynamics, of sediment transport, and of fjord and proglacial ecosystems. Surface meltwater drains through glaciers via supraglacial, englacial and subglacial ...

    • 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 ...

    • Sub-permafrost methane seepage from open-system pingos in Svalbard 

      Hodson, Andrew; Nowak, Aga; Hornum, Mikkel Toft; Senger, Kim; Redeker, Kelly Robert; Christiansen, Hanne H; Jessen, Søren; Betlem, Peter; Thornton, Steve F.; Turchyn, Alexandra V.; Olaussen, Snorre; Marca, Alina (Journal article; Peer reviewed, 2020)
      Methane release from beneath lowland permafrost represents an important uncertainty in the Arctic greenhouse gas budget. Our current knowledge is arguably best developed in settings where permafrost is being inundated by ...
