Fig. 2: Increased turbidity and fluorescence signals within BSBW in the transect north of Severnaya Zemlya and modelled origin of the material.
From: Carbon dioxide sink in the Arctic Ocean from cross-shelf transport of dense Barents Sea water
a,b, Spatial distribution of turbidity (a) and fluorescence (b) measured along the transect. The areas above the solid (absolute salinity <35.06 g kg−1) and below the dashed isolines (potential density anomaly >27.97 kg m−3) indicate BSBW. c, Mean ocean current velocity at 200 m depth simulated by the Finite-Element Sea ice-Ocean Model (FESOM) visualizes the main current field of the Barents Sea branch of the Arctic Boundary Current. d, FESOM-based backward trajectories shown as relative number of particles 0.08 mm ESD (sinking velocity of 1.03 m d−1) as representative particle class for the non-ballasted small suspended particle size fraction <0.1 mm indicate a shelf-based origin of large fractions of the particle load even from the northern Barents Sea. Red square in d indicates the particle endpoint in the observed plume.
