Consequences of Atlantification on a Zooplanktivorous Arctic Seabird
Descamps, Sebastien; Wojczulanis-Jakubas, Katarzyna; Jakubas, Dariusz; Vihtakari, Mikko; Steen, Harald; Karnovsky, Nina J.; Welcker, Jorg; Hovinen, Johanna Emilia Heidi; Bertrand, Philip; Strzelewicz, Agnieszka; Skogseth, Ragnheid; Kidawa, Dorota; Boehnke, Rafał; Błachowiak-Samołyk, Katarzyna (Peer reviewed; Journal article, 2022)Global warming, combined with an increasing influence of Atlantic Waters in the European Arctic, are causing a so-called Atlantification of the Arctic. This phenomenon is affecting the plankton biomass and communities with ... -
Feeding at the front line: Interannual variation in the use of glacier fronts by foraging black-legged kittiwakes
Bertrand, Philip; Strøm, Hallvard; Bêty, Joël; Steen, Harald; Kohler, Jack; Vihtakari, Mikko; Van Pelt, Ward; Yoccoz, Nigel Gilles; Hop, Haakon; Harris, Stephanie M.; Patrick, Samantha C.; Assmy, Philipp; Wold, Anette; Duarte, Pedro; Moholdt, Geir; Descamps, Sébastien (Peer reviewed; Journal article, 2021)Tidewater glacier fronts can represent important foraging areas for Arctic predators. Their ecological importance is likely to change in a warmer Arctic. Their profitability and use by consumers are expected to vary in ... -
Leads in Arctic pack ice enable early phytoplankton blooms below snow-covered sea ic
Assmy, Philipp; Fernández-Méndez, Mar; Duarte, Pedro; Meyer, Amelie; Randelhoff, Achim; Mundy, Christopher John; Olsen, Lasse; Kauko, Hanna M.; Bailey, Allison; Chierici, Melissa; Cohen, Lana; Doulgeris, Anthony Paul; Ehn, Jens K.; Fransson, Agneta; Gerland, Sebastian; Hop, Haakon; Hudson, Stephen R.; Hughes, Nick; Itkin, Polona; Johnsen, Geir; King, Jennifer A.; Koch, Boris P.; Koenig, Zoe; Kwasniewski, Slawomir; Laney, Samuel R.; Nikolaus, Marcel; Pavlov, Alexey K.; Polashenski, Christopher M.; Provost, Christine; Rösel, Anja; Sandbu, Marthe; Spreen, Gunnar; Smedsrud, Lars H.; Sundfjord, Arild; Taskjelle, Torbjørn; Tatarek, Agnieszka; Wiktor, Josef; Wagner, Penelope Mae; Wold, Anette; Steen, Harald; Granskog, Mats A. (Peer reviewed; Journal article, 2017) -
Tidewater glaciers and bedrock characteristics control the phytoplankton growth environment in a fjord in the arctic
Halbach, Laura; Vihtakari, Mikko; Duarte, Pedro; Everett, Alistair; Granskog, Mats; Hop, Haakon; Kauko, Hanna Maria; Kristiansen, Svein; Myhre, Per Inge; Pavlov, Alexey K.; Pramanik, Ankit; Tatarek, Agnieszka; Torsvik, Tomas; Wiktor, Józef Maria; Wold, Anette; Wulff, Angela; Steen, Harald; Assmy, Philipp (Journal article; Peer reviewed, 2019)Meltwater discharge from tidewater glaciers impacts the adjacent marine environment. Due to the global warming, tidewater glaciers are retreating and will eventually terminate on land. Yet, the mechanisms through which ... -
Tidewater glaciers as “climate refugia” for zooplankton-dependent food web in Kongsfjorden, Svalbard
Hop, Haakon; Wold, Anette; Vihtakari, Mikko; Assmy, Philipp; Kuklinski, Piotr; Kwasniewski, Slawomir; Griffith, Gary; Pavlova, Olga; Duarte, Pedro; Steen, Harald (Peer reviewed; Journal article, 2023)With climate warming, many tidewater glaciers are retreating. Fresh, sediment-rich sub-glacial meltwater is discharged at the glacier grounding line, where it mixes with deep marine water resulting in an upwelling of a ... -
Wind-driven upwelling of iron sustains dense blooms and food webs in the eastern Weddell Gyre
Moreau, Sebastian; Hattermann, Tore; de Steur, Laura; Kauko, Hanna Maria; Ahonen, Heidi; Ardelan, Murat van; Assmy, Philipp; Chierici, Melissa; Descamps, Sebastien; Dinter, Tilman; Falkenhaug, Tone; Fransson, Agneta; Grønningsæter, Eirik; Hallfredsson, Elvar Halldor; Huhn, Oliver; Lebrun, Anais; Lowther, Andrew; Lübcker, Nico; Monteiro, Pedro; Peeken, Ilka; Roychoudhury, Alakendra; Różańska, Magdalena; Ryan-Keogh, Thomas; Sanchez Puerto, Nicolas; Singh, Asmita; Simonsen, Jan Henrik; Steiger, Nadine; Thomalla, Sandy J.; van Tonder, Andre; Wiktor, Josef M; Steen, Harald (Peer reviewed; Journal article, 2023)The Southern Ocean is a major sink of anthropogenic CO2 and an important foraging area for top trophic level consumers. However, iron limitation sets an upper limit to primary productivity. Here we report on a considerably ...
