This SeaWiFS view of Alaska (upper right) and the Bering Sea (center), collected on April 13, 2002, reveals an unmistakable wave of dust (brownish pixels) traveling southward along Alaskas western coastline and over the Aleutian Island chain. The dust, probably from East Asia, is easily distinguished from the bright white clouds (lower left) and the snow and ice covered surfaces on and around Alaska.

Another wave of Asian dust was observed arriving on the northwestern shores of North America from the massive dust storm that originated in China on March 17, 2002. This latest SeaWiFS scene was acquired on April 13.
