The greyish haze of smoke from forest fires in eastern Russia obscured parts of the Sea of Okhotsk on May 10, 2002. Much of the snow- and ice-covered landscape of Northeast Asia is also visible in this true-color scene, acquired by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS). Dark greenish swirls indicating the presence of a large phytoplankton bloom can also be seen in the surface waters of the Pacific Ocean where the overlying smoke is not too thick.
