DOIs (Digital Object Identifier) for RADARSAT-1 Data

This 1998 RADARSAT-1 image reveals grease ice along a pack-ice front in the Bering Sea. Grease ice forms after frazil (slush-like ice) crystals are pushed against each other. When the fragile "arms" of the crystals break and form a mixture of damaged crystals and crystal remnants, the result is grease ice—an oily-looking "ice soup" on the water surface. Its viscous nature smooths out small ocean waves. © CSA, 1998.
