Sea Ice Moves
At every stage—from the way it freezes to the way it melts—sea ice is a dynamic force. The ability of radar to track sea-ice motion enables understanding of its far-reaching, global effects.
First the temperature drops. Then ice crystals develop. And that’s just the beginning of the story.
As sea ice matures, its many forms are almost always on the move, driven by winds and currents.
The melting of sea ice drives ecosystems, affects global climate, and is opening the Arctic to shipping and exploration.
