KidSat : Sea Ice Definitions

Introductory definitions for interpreting ice images.


1. Ice floe - Blanketed by snow, pancake ice cements into floes, which buckle as they ram against one another and slide around.

2. Pancake ice - Ice spins around in waves and thickens into free floating ice disks, some reaching 8 ft. in diameter.

3. Sea-Ice Sheets & Pack ice - As winter deepens pancake ice enlarges and crowds together.

4. Shuga ice or Grease Ice - Early ice that forms as the temperature falls and small ice crystals clump together into congealed greasy-ice slicks.

5. Young ice or Frazil Ice - Quickly frozen ice about an eight-inch-long that may contain minute organisms.

6. Open water - Unfrozen sea that may appear a very deep or dark blue.

7. Fast ice - Ice attached to the land.

8. Clouds - White puffs that tend to cast shadows over the ice and may be confused with snow on the ice surface which do not cast shadows.
