    • Consolidation of fresh ice ridges for different scales 

      Salganik, Evgenii; Høyland, Knut Vilhelm; Maus, Sønke (Peer reviewed; Journal article, 2020)
      This study characterizes the refreezing process of deformed ice. Twenty laboratory experiments in ice ridge consolidation were conducted to study the influence of ridge blocks size, initial temperature, and top surface ...

    • 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 ...

    • Location of studies and evidence of effects of herbivory on Arctic vegetation: a systematic map 

      Soininen, Eeva M; Barrio, Isabel C.; Bjørkås, Ragnhild; Björnsdóttir, Katrin; Ehrich, Dorothee; Hopping, Kelly A.; Kaarlejarvi, E.; Kolstad, Anders Lorentzen; Abdulmanova, Svetlana; Björk, Robert G.; Bueno, C.

S.; Hwang, Bernice; Jepsen, Jane Uhd; Kamenova, Stefaniya; Kater, Ilona; Koltz, Amanda; Kristensen, Jeppe A.; Little, Chelsea J.; Macek, Petr; Mathisen, Karen Marie; Metcalfe, Daniel B.; Mosbacher, Jesper Bruun; Mörsdorf, M.; Park, Taejin; Propster, Jeffrey; Roberts, Aradhana J; Serrano, E; Spiegel, Marcus P.; Tamayo, Mariana; Tuomi, Maria Wilhelmina; Verma, Megha; Vuorinen, Katariina Elsa Maria; Väisänen, Maria; Wal, Rene van der; Wilcots, Megan; Yoccoz, Nigel; Speed, James David Mervyn (Peer reviewed; Journal article, 2021)
      Herbivores modify the structure and function of tundra ecosystems. Understanding their impacts is necessary to assess the responses of these ecosystems to ongoing environmental changes. However, the effects of herbivores ...

    • Predicting vessel speed in the Arctic without knowing ice conditions using AIS data and decision trees 

      Rao, Prithvi S.; Kim, Ekaterina; Smestad, Bjørnar Brende; Asbjørnslett, Bjørn Egil; Bhattacharyya, Anirban (Peer reviewed; Journal article, 2021)
      The vessel speed is one of the important parameters that govern safety, emergency, and transport planning in the Arctic. While previous studies have traditionally relied on physics-based simulations to predict vessel's ...

    • 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)
