    • 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 ...

    • Quantifying false bottoms and under-ice meltwater layers beneath Arctic summer sea ice with fine-scale observations 

      Smith, Madison M.; von Albedyll, Louisa; Raphael, Ian A.; Lange, Benjamin; Matero, Ilkka; Salganik, Evgenii; Webster, Melinda; Granskog, Mats A.; Fong, Allison; Lei, Ruibo; Light, Bonnie (Peer reviewed; Journal article, 2022)
      Kartlegging av ferskvannslag og dannelse av falsk bunnis under sjøisen ved sommarsmelting i sentrale Polhavet Sjøisen i Polhavet er i rask endring. Den er blitt mye tynnere i løpet av de siste tiårene, havet og atmosfæren ...

    • 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 ...

    • 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 ...
