Arctic Ocean
The Arctic is the smallest of the world's oceans, centered
roughly on the North Pole. It borders on Russia, Canada, and Alaska, and includes the Bering Sea.
Above 75 degrees north latitude, the entire ocean is covered with
a layer of ice. Below that latitude, the ice is seasonal, but in
the winter still covers nearly the entire ocean at a depth of
between six and twelve feet. Over time, the sea ice loses its
salinity; in this form, known as polar pack, it can be melted
down and used for drinking water.
