δ18O (the stable oxygen isotope ratio)-salinity relationships at five trough stations (colored circles with numbers showing the pressure where water samples were obtained), ice front stations (purple symbols), and mouth of LHB (red symbols). Two dashed lines extending from “mCDW” denote lines connecting two endmembers of “mCDW” with “glacier” and “sea ice”, respectively. Note that δ18O-salinity relationships for “glacier” and “sea ice” endmembers are beyond the range of plot.
