• Different mechanisms of Arctic first-year sea-ice ridge consolidation observed during the MOSAiC expedition 

      Salganik, Evgenii; Lange, Benjamin; Itkin, Polona; Divine, Dmitry; Katlein, Christian; Nicolaus, Marcel; Hoppmann, Mario; Neckel, Niklas; Ricker, Robert; Høyland, Knut Vilhelm; Granskog, Mats (Peer reviewed; Journal article, 2023)
      Sea-ice ridges constitute a large fraction of the ice volume in the Arctic Ocean, yet we know little about the evolution of these ice masses. Here we examine the thermal and morphological evolution of an Arctic first-year ...
    • Observations of preferential summer melt of Arctic sea-ice ridge keels from repeated multibeam sonar surveys 

      Salganik, Evgenii; Lange, Benjamin Allen; Katlein, Christian; Matero, Ilkka; Anhaus, Philipp; Muilwijk, Morven; Høyland, Knut Vilhelm; Granskog, Mats (Peer reviewed; Journal article, 2023)
      Sea-ice ridges constitute a large fraction of the total Arctic sea-ice area (up to 40 %–50 %); nevertheless, they are the least studied part of the ice pack. Here we investigate sea-ice melt rates using rare, repeated ...
    • Overview of the MOSAiC expedition: Snow and sea ice 

      Marcel, Nicolaus; Perovich, Donald; Spreen, Gunnar; Granskog, Mats; Divine, Dmitry; Gerland, Sebastian; Gradinger, Rolf Rudolf; Høyland, Knut Vilhelm; Lange, Benjamin; Salganik, Evgenii (Journal article; Peer reviewed, 2022)
      Year-round observations of the physical snow and ice properties and processes that govern the ice pack evolution and its interaction with the atmosphere and the ocean were conducted during the Multidisciplinary drifting ...
    • Snowmelt contribution to Arctic first-year ice ridge mass balance and rapid consolidation during summer melt 

      Lange, Benjamin A.; Salganik, Evgenii; Macfarlane, Amy; Schneebeli, Martin; Høyland, Knut Vilhelm; Gardner, Jessie; Müller, Oliver; Divine, Dmitry; Kohlbach, Doreen; Katlein, Christian; Granskog, Mats (Peer reviewed; Journal article, 2023)
      Sea ice ridges are one of the most under-sampled and poorly understood components of the Arctic sea ice system. Yet, ridges play a crucial role in the sea ice mass balance and have been identified as ecological hotspots ...
    • Svalbard fjord environments with land-fast sea ice as arenas for climate research, monitoring, remote sensing validation, and dedicated process studies 

      Gerland, Sebastian; Divine, Dmitry V; Fransson, Agneta; Granskog, Mats; Pavlova, Olga; Chierici, Melissa; Høyland, Knut Vilhelm; Johansson, Malin; Marchenko, Aleksey (Peer reviewed; Journal article, 2020)
      During winter and spring, parts of Svalbard fjords are covered with land-fast sea ice. The extent of fast ice areas has decreased during the last two decades, and seasons with fjord ice cover have on average become shorter. ...
    • Temporal evolution of under-ice meltwater layers and false bottoms and their impact on summer Arctic sea ice mass balance 

      Salganik, Evgenii; Katlein, Christian; Lange, Benjamin; Matero, Ilkka; Lei, Ruibo; Fong, Allison A.; Fons, Steven; Divine, Dmitry; Oggier, Marc; Castellani, Giulia; Bozzato, Deborah; Chamberlain, Emelia; Hoppe, Clara J. M.; Müller, Oliver; Gardner, Jessie; Rinke, Annette; Simoes Pereira, Patric; Ulfsbo, Adam; Marsay, Christopher; Webster, Melinda; Maus, Sønke; Høyland, Knut Vilhelm; Granskog, Mats (Peer reviewed; Journal article, 2023)
      Nåtidens endringer av havisen i Polhavet medfører ikke bare tynnere is og redusert isutbredelse, men også endringer i utbredelsen av eldre, flerårig is. Gjennom de siste 20 årene har andelen med flerårig havis, havis som ...
