Cryosat watches sea ice growth
Scientists working on the European Space Agency's Cryosat mission say the spacecraft is now turning out excellent data on the thickness of Arctic sea ice.
The team has released calibrated data showing the growth of ice from the start of the freeze-up up in autumn (2010) to deep winter conditions in March (2011).
In the central Arctic basin, the volume of ice at March is calculated by Cryosat to be about 14,500 cubic km.
Mission scientist Dr Seymour Laxon explained to science correspondent Jonathan Amos how the satellite is prepared to get good data.
