A decade of particle flux measurements providse the basis for a comparison of the eastern and western province s of the Nordic Seas. Ice-related physical and biological seasonality as well as pelagic settings jointly control fluxes in the western Polar Province which receive s southward flowing water of Polar origin. Sediment trap data from this realm highlight a predominantly physical flux control which leads to exports of siliceous particle s within the biological marginal ice zone as a prominent contributor. In the northward flowing waters of the eastern Atlanti c Province, feeding strategies, life histories and the succession ofdominant mesozooplankters (copepods and pteropods) are central in controlling fluxes. Furthermore, more calcareous matter is exported here with a shift in flux seasonality towards summer I autumn. Dominant pelagic processes modeled numerically as to their impact on annual organic carbon exports for both provinces confirm that interannual flux variability is related to changes in ... : Supplement to: Peinert, Rolf; Antia, Avan N; Bauerfeind, Eduard; von Bodungen, Bodo; Haupt, Olaf; Krumbholz, Marita; Peeken, Ilka; Ramseier, René O; Voss, Maren; Zeitzschel, Bernt (2001): Particle flux variability in the polar and Atlantic biogeochemical provinces of the Nordic Seas.
