Sea water freezing

The freezing point of sea water depends upon its salinity.

In polar regions, sea water salinity is about 35 ppt (parts per thousand). Freshwater from rivers has a salinity value of 0.5 ppt or less.

The freezing temperature of water decreases by 0.28°C for every 5 ppt increase in salinity. Sea water in the polar regions begins freezing at about –1.8°C.
