Long time series of deep water particle flux in three biogeochemical provinces of the northeast Atlantic
Long-term observations of the deep ocean particle flux from three sites in the northeast Atlantic (33 degrees N, 22 degrees W; 47 degrees N, 20 degrees W; 54 degrees N, 20 degrees W) provide the basis for comparison and characterization of the biogeochemical provinces in terms of sedimentation patte...

Long-term observations of the deep ocean particle flux from three sites in the northeast Atlantic (33 degrees N, 22 degrees W; 47 degrees N, 20 degrees W; 54 degrees N, 20 degrees W) provide the basis for comparison and characterization of the biogeochemical provinces in terms of sedimentation pattern. Deep ocean particle flux data (2000 in) for fluxes of total mass and the flux composition are presented and compared to published sediment trap data from this area to consider regional-scale variations in the quantity and composition of settling material. The observations show that in the northeast Atlantic gradient of decreasing mass flux from North to South, exists consistent with known changes of biological productivity in surface waters.
