ARCTIC OCEAN - A multi-year ice floe slides down the starboard side of the Coast Guard Cutter Healy Aug. 11, 2009, as the ship heads north into even thicker ice. "You can tell that this is a multi-year ice floe by the light blue melt ponds that have formed on top of the floe," said Pablo Clemente-Colón, chief scientist at the U.S. National Ice Center.

Two school teachers stand outside a neighbor's destroyed adobe home in Cauquenes, Chile following the M 8.8 earthquake on Feb. 27, 2010. Reconstruction in this ancient city will be based on reinforced concrete rather than highly vulnerable adobe.

Bristle-thighed Curlews (Numenius tahitiensis) are large shorebirds that breed in Alaska and spend the nonbreeding season on atolls and small islands throughout Oceania. This life history pattern requires curlews to migrate long distances each year.

Freshwater flowing over the Faka Union Canal Weir #1 near Port of the Islands, Collier County, Florida. During cold weather, freshwater flows here can maintain a downstream salinity gradient that creates a warm water refuge for manatees.
