Esa's Cryosat mission monitors continuing Arctic winter ice decline

11 September 2013 Last updated at 11:48 BST

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.

This animation shows the ebb and flow of sea-ice thickness and area during Cryosat's time in orbit.
