Based on shell concentrations of the planktonic foraminifera Neogloboquadrina pachyderma from vertically resolved plankton tow samples during cruises ARK-IV/3, ARK-XI/1, ARK-XIII/2, ARK-XV/1, ARK-XV/2, MSM44, MSM66, M21/4, M21/5, M39/4, MSM09/2, NEWP-92, NEWP-93, PS93.1, PS31, PS78 and (average) shell weights, the calcite mass flux is calculated (mg m-2 d¬-1).

Further details:The calcite mass flux is calculated after Schiebel and Hemleben (2000): Calcite mass flux (mg m-2 d^-1) = shell weight (mg) * shell concentration (ind. m^-3) * sinking velocity (m d^-1).The sinking velocity is calculated after Takahashi and Bé (1984):Foraminifera sinking velocity (m d^-1) = 10^2.06 * shell weight (µg)^0.64.Depending on the availability of shell weight data, either measured or average values where used, which are listed in the column “shell weight type” as follows:Measured average: Shell weight was measured on the shells of the samples as a bulk weight, leading to an average value for individual shells.Regional average: Based on measured values from the same sampling region, but not the same samples.Total average: Based on all measured values from the study in the Subarctic and Arctic realm, used where no measurements from the same region are present .Regional and total averages were calculated based on measurements from shells from below the productive zone, as those are the shells representing the export flux.
