Carbon export in the seasonal sea ice zone north of Svalbard from winter to late summer
Dybwad, Christine; Assmy, Philipp; Olsen, Lasse Mork; Peeken, Ilka; Nikolopoulos, Anna; Krumpen, Thomas; Randelhoff, Achim; Tatarek, Agnieszka; Wiktor, Józef M.; Reigstad, Marit (Peer reviewed; Journal article, 2021)Phytoplankton blooms in the Arctic Ocean's seasonal sea ice zone are expected to start earlier and occur further north with retreating and thinning sea ice cover. The current study is the first compilation of phytoplankton ... -

Sanz-Martín, Marina; Chierici, Melissa; Mesa, Elena; Carrillo-de-Albornoz, Paloma; Delgado-Huertas, Antonio; Agusti, Susana; Reigstad, Marit; Kristiansen, Svein; Wassmann, Paul; Duarte, Carlos M. (Journal article; Peer reviewed, 2018)The European Sector of the Arctic Ocean is characterized by low CO2 concentrations in seawater during spring and summer, largely due to strong biological uptake driven by extensive plankton blooms in spring. The spring ... -
