    • Greenland surface air temperature changes from 1981 to 2019 and implications for ice-sheet melt and mass-balance change 

      Hanna, Edward; Cappelen, John; Fettweis, Xavier; Mernild, Jacob Sebastian Haugaard; Mote, Thomas L.; Mottram, Ruth; Steffen, Konrad; Ballinger, Thomas J.; Hall, Richard J. (Peer reviewed; Journal article, 2020)
      We provide an updated analysis of instrumental Greenland monthly temperature data to 2019, focusing mainly on coastal stations but also analysing ice‐sheet records from Swiss Camp and Summit. Significant summer (winter) ...

    • 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. ...

    • Spatially consistent microbial biomass and future cellular carbon release from melting Northern Hemisphere glacier surfaces 

      Stevens, Ian T.; Irvine-Fynn, Tristram D. L.; Edwards, Arwyn; Mitchell, Andrew C.; Cook, Joseph M.; Porter, Philip R.; Holt, Tom O.; Huss, Matthias; Fettweis, Xavier; Moorman, Brian J.; Sattler, Birgit; Hodson, Andrew (Peer reviewed; Journal article, 2022)
      Melting glacier ice surfaces host active microbial communities that enhance glacial melt, contribute to biogeochemical cycling, and nourish downstream ecosystems; but these communities remain poorly characterised. Over the ...
