    • Changes in Sea-Ice Protist Diversity With Declining Sea Ice in the Arctic Ocean From the 1980s to 2010s 

      Hop, Haakon; Vihtakari, Mikko; Bluhm, Bodil; Assmy, Philipp; Poulin, Michel; Gradinger, Rolf; Peeken, Ilka; von Quillfeldt, Cecilie; Olsen, Lasse Mork; Zhitina, Ludmila; Melnikov, Igor A. (Journal article; Peer reviewed, 2020)
      The large declines in Arctic sea-ice age and extent over the last decades could have altered the diversity of sea-ice associated unicellular eukaryotes (referred to as sea-ice protists). A time series from the Russian ...

    • An ecosystem-scale litter and microplastics monitoring plan under the Arctic Monitoring and Assessment Programme (AMAP) 

      Provencher, Jennifer; Kögel, Tanja; Lusher, Amy; Vorkamp, Katrin; Gomiero, Alessio; Peeken, Ilka; Granberg, Maria; Hammer, Sjúrður; Baak, Julia; Larsen, Jan Rene; Farmen, Eivind (Journal article; Peer reviewed, 2022)
      Lack of knowledge on levels and trends of litter and microplastics in the Arctic, is limiting our understanding of the sources, transport, fate, and effects is hampering global activities aimed at reducing litter and ...

    • Editorial: Effects of Ice Loss on Marine Biodiversity 

      Peeken, Ilka; Tandberg, Anne Helene Solberg; Linse, Katrin (Journal article; Peer reviewed, 2021)
      The Arctic and Antarctic oceans are undergoing changes in the extent of their sea-ice and ice-shelves (IPCC, in press). These have important impacts on the biodiversity, structure, and function of sea ice biota, pelagic ...

    • First phytoplankton community assessment of the Kong Håkon VII Hav, Southern Ocean, during austral autumn

      We studied phytoplankton and protozooplankton community composition based on light microscopy, flow cytometry, and photosynthetic pigment data in the Atlantic sector of the Southern Ocean during March 2019 (early austral ...

    • Future monitoring of litter and microplastics in the Arctic—challenges, opportunities, and strategies 

      Provencher, Jennifer F.; Aliani, Stefano; Bergmann, Melanie; Bourdages, Madelaine; Buhl-Mortensen, Lene; Galgani, Francois; Gomiero, Alessio; Granberg, Maria; Grøsvik, Bjørn Einar; Hamilton, Bonnie M.; Kögel, Tanja; Larsen, Jan René; Lusher, Amy; Mallory, Mark L; Murphy, Peter; Peeken, Ilka; Primpke, Sebastian; Strand, Jakob; Vorkamp, Katrin (Journal article; Peer reviewed, 2022)
      The Arctic Monitoring and Assessment Programme has published a plan and guidelines for the monitoring of litter and microplastics (MP) in the Arctic. Here, we look beyond suggestions for immediate monitoring and discuss ...

    • A red tide in the pack ice of the Arctic Ocean 

      Olsen, Lasse Mork; Duarte, Pedro; Peralta-Ferriz, Cecilia; Kauko, Hanna Maria; Johansson, Malin; Peeken, Ilka; Różańska-Pluta, Magdalena; Tatarek, Agnieszka; Wiktor, Jozef; Fernández-Méndez, Mar; Wagner, Penelope Mae; Pavlov, Alexey K.; Hop, Haakon; Assmy, Phillipp (Peer reviewed; Journal article, 2019-07-02)
      n the Arctic Ocean ice algae constitute a key ecosystem component and the ice algal spring bloom a critical event in the annual production cycle. The bulk of ice algal biomass is usually found in the bottom few cm of the ...

    • The seeding of ice algal blooms in Arctic pack ice: The multiyear ice seed repository hypothesis 

      Olsen, Lasse Mork; Laney, Samuel R.; Duarte, Pedro; Kauko, Hanna M.; Fernández-Méndez, Mar; Mundy, Christopher John; Rösel, Anja; Meyer, Amelie; Itkin, Polona; Cohen, Lana; Peeken, Ilka; Tatarek, Agnieszka; Róźańska-Pluta, Magdalena; Wiktor, Josef; Taskjelle, Torbjørn; Pavlov, Alexey; Hudson, Stephen R.; Granskog, Mats A.; Hop, Haakon; Assmy, Philipp (Peer reviewed; Journal article, 2017-07)
      During the Norwegian young sea ICE expedition (N-ICE2015) from January to June 2015 the pack ice in the Arctic Ocean north of Svalbard was studied during four drifts between 83° and 80°N. This pack ice consisted of a mix ...
