Esa's Cryosat mission observes continuing Arctic winter ice decline
By Jonathan Amos
Science correspondent, BBC News, Edinburgh
The volume of sea ice in the Arctic hit a new low this past winter, according to observations from the European Space Agency's (Esa) Cryosat mission.
During March/April - the time of year when marine floes are at their thickest - the radar spacecraft recorded just under 15,000 cu km of ice.
In its three years of full operations, Cryosat has witnessed a continuing shrinkage of winter ice volume.
It underlines, say scientists, the long-term decline of the floes.
