Definition:
Sea ice is frozen ocean water.
It occurs in both the Arctic and Antarctic and can cover large extents of
water.
It grows during the winter months and melts during the summer months, but some
sea ice remains all year in certain regions.
About 15 percent of the world's oceans are covered by sea ice during part of
the year.
The freezing temperature of salt water is lower than fresh water; ocean
temperatures must reach -1.8° C Celsius (28.8°F) to freeze.
