Is there freshwater parts of the antarctic and arctic polar ice caps?

Question

Does anyone know the average salinity of the Polar Ice caps, or the salinity of different parts of them

Answer 1

In the polar ice-caps, except for the ice found on the coast, the rest is frozen fresh-water with an average salinity of only 2-3% i.e. just 2-3% of the ice is saline.
These frozen sheets of ice are known as ice-sheets and they sometimes reach the ocean as huge ice-cubes by the names of icebergs.They are 2-5 km thick in Antarctica.

Answer 2

Polar regions are higher in salinity than most of the oceans due to the yearly freezing and melting of the ice, making it more concentrated. The ice sheet in the north that is actually on the ocean itself is simply frozen salt water and is not fresh water ice. The Antarctic ice sheet is over land and there from millions and millions of years of snow that never can get warm enough to melt and is fresh water ice.

Answer 3

Actually when water freezes, the salt water separates from the freshwater allowing only the freshwater to freeze. This is why the salinity is higher at greater latitudes, there is limited fresh water due to freezing. The salinity of the polar icecaps would therefore be relatively close to 0ppt.

Answer 4

fresh water.Salinity only is found along the cost sense most of antarctic . Possible less than 80 %.
