Is Arctic ice thinning?

Scientists have long used satellite imagery to illustrate the shrinking extent of the Arctic sea ice. Now they’ve got satellite data that will provide regular updates on whether the ice is getting thinner as well.

The first ice thickness map from the European Space Agency’s CryoSat spacecraft was released Tuesday at an air show in Paris. It was compiled with data collected in January and February.

The map shows, for example, the ice is thickest near the North Pole and off the coasts of Greenland and northeastern Canada. It thins as it stretches out towards Alaska and Russia.
