Arctic – Atlantic Exchange of the Dissolved Micronutrients Iron, Manganese, Cobalt, Nickel, Copper and Zinc With a Focus on Fram Strait
Krisch, Stephan; Hopwood, Mark J.; Roig, Stéphane; Gerringa, Loes J. A.; Middag, Rob; Rutgers van der Loeff, Michiel M.; Petrova, Mariia V.; Lodeiro, Pablo; Colombo, Manuel; Cullen, Jay T.; Jackson, Sarah L.; Heimbürger‐Boavida, Lars‐Eric; Achterberg, Eric P. (Global Biogeochemical Cycles, 2022-05-16)The Arctic Ocean is considered a source of micronutrients to the Nordic Seas and the North Atlantic Ocean through the gateway of Fram Strait (FS). However, there is a paucity of trace element data from across the Arctic ... -
Nutrient regulation of late spring phytoplankton blooms in the midlatitude North Atlantic
Browning, Thomas J.; Al-Hashem, Ali A.; Hopwood, Mark J.; Engel, Anja; Wakefield, Ewan D.; Achterberg, Eric P. (Limnology and Oceanography, 2019)The duration and magnitude of the North Atlantic spring bloom impacts both higher trophic levels and oceanic carbon sequestration. Nutrient exhaustion offers a general explanation for bloom termination, but detail on which ... -
Quantifying Ice‐Sheet Derived Lead (Pb) Fluxes to the Ocean; A Case Study at Nioghalvfjerdsbræ
Krisch, Stephan; Huhn, Oliver; Al‐Hashem, Ali; Hopwood, Mark J.; Lodeiro, Pablo; Achterberg, Eric P. (Geophysical Research Letters, 2022-11-07)Concentrations of the toxic element lead (Pb) are elevated in seawater due to historical emissions. While anthropogenic atmospheric emissions are the dominant source of dissolved Pb (dPb) to the Atlantic Ocean, evidence ... -
Sediment Release in the Benguela Upwelling System Dominates Trace Metal Input to the Shelf and Eastern South Atlantic Ocean
Liu, Te; Krisch, Stephan; Xie, Ruifang C.; Hopwood, Mark J.; Dengler, Marcus; Achterberg, Eric P. (Global Biogeochemical Cycles, 2022-09-25)Upwelling of subsurface waters injects macronutrients (fixed N, P, and Si) and micronutrient trace metals (TMs) into surface waters supporting elevated primary production in Eastern Boundary Upwelling Regions. The eastern ...
