Development, productivity, and seasonality of living planktonic foraminiferal faunas and Limacina helicina in an area of intense methane seepage in the Barents Sea
Ofstad, Siri; Meilland, Julie; Zamelczyk, Katarzyna; Chierici, Melissa; Fransson, Agneta; Gründger, Friederike; Rasmussen, Tine Lander (Journal article; Peer reviewed, 2020)Although the plankton communities in the Barents Sea have been intensely studied for decades, little is known about the living planktonic foraminiferal (LPF) and pteropod faunas, especially those found at methane seep ... -
Distribution and Abundances of Planktic Foraminifera and Shelled Pteropods During the Polar Night in the Sea-Ice Covered Northern Barents Sea
Zamelczyk, Katarzyna; Fransson, Agneta; Chierici, Melissa; Jones, Elizabeth Marie; Meilland, Julie; Anglada-Ortiz, Griselda; Hodal Lødemel, Helene (Peer reviewed; Journal article, 2021)Planktic foraminfera and shelled pteropods are important calcifying groups of zooplankton in all oceans. Their calcium carbonate shells are sensitive to changes in ocean carbonate chemistry predisposing them as an important ... -
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 (Peer reviewed; Journal article, 2021)Planktic foraminifera and shelled pteropods are some of the major producers of calcium carbonate (CaCO3) in the ocean. Their calcitic (foraminifera) and aragonitic (pteropods) shells are particularly sensitive to changes ... -
Shell density of planktonic foraminifera and pteropod species Limacina helicina in the Barents Sea: Relation to ontogeny and water chemistry
Ofstad, Siri; Zamelczyk, Katarzyna; Kimoto, Katsunori; Chierici, Melissa; Fransson, Agneta; Rasmussen, Tine Lander (Peer reviewed; Journal article, 2021)Planktonic calcifiers, the foraminiferal species Neogloboquadrina pachyderma and Turborotalita quinqueloba, and the thecosome pteropod Limacina helicina from plankton tows and surface sediments from the northern Barents ... -
The last two millennia: climate, ocean circulation and paleoproductivity inferred from planktic foraminifera, south-western Svalbard margin
Zamelczyk, Katarzyna; Rasmussen, Tine Lander; Raitzsch, Markus; Chierici, Melissa (Peer reviewed; Journal article, 2020)We reconstruct climate and changes in water-mass properties in relation to variations in palaeoproductivity at the south-western Svalbard margin throughout the last 2000 years. Environmental conditions in subsurface (ca. ...
