Coastal conduit in southwestern Hudson Bay (Canada) in summer: Rapid transit of freshwater and significant loss of colored dissolved organic matter

Distributions of freshwater (sea‐ice melt and runoff) were investigated along inshore‐offshore sections in southwestern Hudson Bay for fall conditions. Conductivity‐temperature‐density profiles and bottle samples collected for salinity, oxygen isotope ( δ 18 O), and colored dissolved organic matter (CDOM) analyses were used to discriminate between contributions of river water (RW) and sea‐ice melt (SIM). Stations had a fresh summer surface mixed...
