    • Pelagic calcium carbonate production and shallow dissolution in the North Pacific Ocean 

      Ziveri, Patrizia; Gray, William Robert; Anglada Ortiz, Griselda; Manno, Clara; Grelaud, Michael; Incarbona, Alessandro; Rae, James William Buchanan; Subhas, Adam V.; Pallacks, Sven; White, Angelicque; Adkins, Jess F.; Berelson, William (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-20)
      Planktonic calcifying organisms play a key role in regulating ocean carbonate chemistry and atmospheric CO<sub>2</sub>. Surprisingly, references to the absolute and relative contribution of these organisms to calcium carbonate production are lacking. Here we report quantification of pelagic calcium carbonate production in the North Pacific, providing new insights on the contribution of the three ...

    • Planktic foraminiferal and pteropod contributions to carbon dynamics in the Arctic Ocean (north Svalbard margin) 

      Anglada-Ortiz, Griselda; Zamelczyk, Katarzyna; Meilland, Julie; Ziveri, Patrizia; Chierici, Melissa; Fransson, Agneta; Rasmussen, Tine Lander (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-09)
      Planktic foraminifera and shelled pteropods are some of the major producers of calcium carbonate (CaCO<sub>3</sub>) in the ocean. Their calcitic (foraminifera) and aragonitic (pteropods) shells are particularly sensitive to changes in the carbonate chemistry and play an important role for the inorganic and organic carbon pump of the ocean. Here, we have studied the abundance distribution of planktic ...

    • Seasonality of marine calcifiers in the northern Barents Sea: Spatiotemporal distribution of planktonic foraminifers and shelled pteropods and their contribution to carbon dynamics 

      Ortiz, Griselda Anglada; Meilland, Julie; Ziveri, Patrizia; Chierici, Melissa; Fransson, Agneta; Jones, Elizabeth Marie; Rasmussen, Tine Lander (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-07)
      The Barents Sea is presently undergoing rapid warming and the sea-ice edge and the productive zones are retreating northward at accelerating rates. Planktonic foraminifers and shelled pteropods are ubiquitous marine calcifiers that play an important role in the carbon budget and being particularly sensitive to ocean biogeochemical changes and ocean acidification. Their distribution at high latitudes ...
