Schematic of current flow paths, and location of stations (red dots) sampled during GEOTRACES expeditions GN05 (2016) in Fram Strait, GN04 (2015) in the Barents Sea Opening, and GN02/GN03 (2015) in the Canadian Arctic Archipelago. Black, dotted arrows highlight the sections which are shown in Fig. 2 (Fram Strait, GN05) and in Supplementary Fig. 4 (Barents Sea Opening, GN04). For a depiction of the CAA section, we refer the reader to ref. 43. Warm, saline (cold, fresher) Atlantic-derived (Arctic-derived) currents are depicted in bold-orange (bold-white): Norwegian Atlantic Front Current (NwAFC), Norwegian Atlantic Slope Current (NwASC), Barents Sea Branch (BSB), West Spitsbergen Current (WSC), Transpolar Drift (TPD, including Polar Surface Water), East Greenland Current (EGC), Baffin Current (BC). Station numbers are indicated in Supplementary Figs. 1 and 2. Figure produced by Ocean Data View98.
