Planktic foraminiferal and pteropod contributions to carbon dynamics in the Arctic Ocean (north Svalbard margin)
Planktic foraminifera and shelled pteropods are some of the major producers of calcium carbonate (CaCO 3 ) 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 o...

Planktic foraminifera and shelled pteropods are some of the major producers of calcium carbonate (CaCO 3 ) 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 foraminifera and pteropods (individuals m –3 ) and their contribution to the inorganic and organic carbon standing stocks (μg m –3 ) and export production (mg m –2 day –1 ) along a longitudinal transect north of Svalbard at 81° N, 22–32° E, in the Arctic Ocean.
