    • 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 ...

    • Ice thickness estimates for design of structures 

      Høyland, Knut Vilhelm; Hornnes, Vegard; Salganik, Evgenii; Samardžija, Ilija (Peer reviewed; Journal article, 2023)
      The level ice thickness is perhaps the most important ice property in both engineering and geophysics. Ice action from level ice scales almost linearly with ice thickness and the level ice thickness gives the mode in ice ...

    • Medium-scale consolidation of artificial ice ridge – Part I: surface temperature, thickness and mechanical properties 

      Salganik, Evgenii; Høyland, Knut Vilhelm; Shestov, Aleksey; Løset, Sveinung; Heijkoop, Anne-Niekolai (Journal article; Peer reviewed, 2019)

    • Medium-scale consolidation of artificial ice ridge – Part II: Fracture properties investigation by a splitting test 

      Lu, Wenjun; Shestov, Aleksey; Løset, Sveinung; Salganik, Evgenii; Høyland, Knut Vilhelm (Journal article; Peer reviewed, 2019)
      Sea ice’s fracture properties are in general difficult to measure and there is still on-going debate on the proper way to conduct valid measurements. Among many controversy fracture test conditions, the size of the test ...

    • Medium-scale experiment in consolidation of an artificial sea ice ridge in Van Mijenfjorden, Svalbard 

      Salganik, Evgenii; Høyland, Knut Vilhelm; Shestov, Aleksey (Peer reviewed; Journal article, 2021)
      This study characterizes a consolidation of undeformed level ice and ice ridges. Field investigations were performed in the Van Mijenfjorden, Svalbard for 66 days between February and May of 2017. The thickness and properties ...

    • 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 ...

    • 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 ...

    • Scale-model ridges and interaction with narrow structures, Part 1 Overview and scaling 

      Shestov, Aleksey; Ervik, Åse; Heinonen, Jaakko; Perala, Ilkka; Høyland, Knut Vilhelm; Salganik, Evgenii; Li, Hongtao; van den Berg, Marnix; Jiang, Zongyu; Puolakka, Otto (Chapter, 2020)
