Fig. 4: Monthly mean estimates of dissolved Pb fluxes (in Mg a−1) between September 2015 and August 2016.
From: The Arctic Ocean is a net sink for anthropogenic lead deposited into the Atlantic Ocean
A Dissolved Pb (dPb) fluxes across Fram Strait as part of the West Spitsbergen Current (red diamonds), the East Greenland Current (blue triangles), the Middle section (light blue crosses), the NE Greenland Shelf (grey dots), and Fram Strait fluxes combined (Fram Strait (net), black squares). B Summary of the combined dPb fluxes across the Arctic-Atlantic gateways (purple triangles) including net fluxes across Fram Strait (black squares), the Barents Sea Opening (red diamonds) and the Canadian Arctic Archipelago (brown dots). Positive values indicate an Atlantic flux into the Arctic Ocean. Negative values indicate an Arctic flux toward the North Atlantic Ocean. Visualised from Supplementary Tables 9 and 10.
