Regional distribution of δ18O-derived meteoric water and sea ice melt.
Column inventories (m) of (A) meteoric water, (B) sea ice melt, both derived from discrete δ18O CTD data; negative values indicate net sea ice production. Bathymetry is from Nitsche et al. (2007); coastlines are from MOA2004 (Haran et al., 2013). The four dotted lines in (A) are the station transects plotted in Figure 10.
