Cryosat spots Arctic sea-ice loss.
15 February 2013
The dramatic recent decline in Arctic sea-ice cover is illustrated in new data from Europe's Cryosat mission combined with data from NASA ICESat mission.
Cryosat was launched by the European Space Agency in 2010 and it has been in orbit for two complete winters. The spacecraft uses radar to estimate the Arctic sea ice thickness and volume. Professor Seymour Laxon pioneered the use of satellites to measure sea ice thickness and track global warming.
The latest finding have been published online in the Geophysical Research Letters. The study was lead by Seymour Laxon who solved the problem of separating ice from water in the satellite altimeter signal. His Colleague, Dr Katharine Giles said:
"Seymour's work provided evidence with which to propose and eventually launch the Cryosat mission, which is now - as his last paper describes - providing the first observations of the annual cycle of sea-ice growth and decay throughout the Arctic Ocean".
