The Aleutian Islands, Alaska - Vast stretches of sea ice link Alaska’s Aleutian
Islands (NASA - January 3, 2004). This
chain of volcanic islands stretches in an arc over 1200 miles long from the
Alaskan Peninsula almost to Russia’s Komanorski Islands. They separate the
Bering Sea from the northern Pacific Ocean, and are almost all part of the
Aleutian National Wildlife Reserve. Phytoplankton clouds line the northern edges
of the sea ice, creating a bluish-green halo.
