Sea Ice. Part 1. Bulk Salinity Versus Ice Floe Thickness

摘要

Mathematical expressions have been established for estimating the bulk salinityof Arctic and Antarctic sea ice vs. ice floe thickness. The ice salinity vs. thickness relationships are based on data for over 400 sea ice cores compiled from numerous sources. The results show that the bulk salinity of first year sea ice decreases in an exponential trend with ice sheet thickness. A similar trend reoccurs as the winter ice passes through the melt season. The expression for the bulk salinity S sub B in parts per thousand for first-year sea ice from 10 to 200cm thick is S sub B =4.606 + 91.6O3/TF, where TF the ice floe thickness in centimeters.
