Sea ice is formed from ocean water that freezes, whether along coasts or to the sea floor (fast ice) or floating on the surface (drift ice) or packed together (pack ice). The most important areas of pack ice are the polar ice packs. Because of vast amounts of water added to or removed from the oceans and atmosphere, the behavior of polar ice packs have a significant impact on the global changes in climate.
To the Arctic for CryoSat and beyond
20 March 2017
After the relative quiet of the long dark winter months, the Arctic will be a tad busier over the coming weeks as numerous researchers descend on this harsh, yet fragile environment. Their aim is not to disturb its beauty, but to join forces in an all-out effort to measure ice on land and sea.
Environmental changes in the Arctic are no longer only of interest to scientists.
The need to understand and respond to dwindling polar ice is being given increasing importance at global climate discussions and vital for adopting strategies to mitigate and to adapt to change.
