WebApr 29, 2013 · 1. Salt. The high concentration of salt in ocean water lowers its freezing point from 32° F (0° C) to 28° F (-2° C). As a result, the ambient temperature must reach a lower point in order to freeze the ocean than to freeze freshwater lakes. This freezing-point depression effect is the same reason we throw salt on icy sidewalks in the winter. WebAs these ice sheets and glaciers melt, the water eventually runs into the ocean, causing sea level to rise. Icebergs and frozen seawater also melt in warm temperatures but are not significant contributors to sea level rise. …
