Vertical profiles for bulk salinity in sea ice cores. Vertical profiles of the salinity of bulk sea ice as a function of normalized ice core depth. Median values are indicated by the blue dashed, red dashed-dotted, and green dotted lines for winter, spring and summer, respectively. The data have been binned into 10% depth intervals. The interquartile ranges are represented by the colored-corresponding envelopes. DOI: https://doi.org/10.1525/elementa.217.f4
