A cable protrudes from the ice wall at Explorer's Cover, New Harbor, McMurdo Sound in this photo taken on November 12, 2005. The cable was used for the Remotely Operable Micro-Environmental Observatory (ROMEO), an underwater camera. Connected to onshore equipment and linked by radio to the Internet, ROMEO allowed scientists to study benthic fauna year-round.

After waiting for over two weeks for his mate to return from the sea and relieve him of nest duty, this Adelie penguin's hunger helps him make the decision to abandon his egg in search of fish and krill in the sea. Photo taken December 12, 2002. Known populations of the Adelie penguin have dropped by 65% over the past 25 years.

A whale swims off the Valdes peninsula, Argentina. After summering in the Arctic, whales return to the southern seas each winter to reproduce. From July to November, whales mate and bear their young along the coasts of the Valdes Peninsula in Argentina. Until the 1950s, this migratory marine mammal was extensively hunted for its meat and the oil extracted from its fat, which brought it to the edge of extinction. Protective measures were adopted af

Cebergs and an Adelie penguin, Adelie Land, Antarctica. Antarctica, the sixth continent, is a unique observation point for atmospheric and climatic phenomena; its ancient ice, which trapped air when it was formed, contains evidence of the Earth's climate as it has changed and developed over the past millions of years.

The Commonwealth Glacier in the Transantarctic Mountains, seen on February 4, 2007. The glacier was named by the British Antarctic Expedition led by Robert Falcon Scott (1910-1913) after the Commonwealth of Australia. This glacier flows in a southeasterly direction, west of Mount Coleman, in Victoria Land.

The Calkin Glacier, seen on November, 2003. The glacier is located in the Taylor Valley in Victoria Land, named for Parker Calkin, US Antarctic Program geologist who conducted research in the area during the 1960-61 and 1961-62 field seasons.

The setting sun glints off the Amazon River and numerous lakes in its floodplain in this astronaut photograph from August 19, 2008. About 150 kilometers of the Amazon is shown here, about 1,000 kilometers inland from the Atlantic Ocean. This image was acquired on August 19, 2008 by the by the Expedition 17 crew of the International Space Station.

Steep Antarctic mountains channel the flowing ice sheet into a fast-moving river of ice named Byrd Glacier located near McMurdo Station. The glacier plunges through a deep, 15-mile-wide valley in the Transatlantic Mountains to create a 100-mile-long, rock-floored ice stream. This image, captured by the Landsat 7 satellite on December 24, 1999, shows part of the Byrd Glacier flowing through the Transatlantic Mountains.

During the last ice age, Canada's Akimiski Island was buried under several thousand meters of ice, but since its retreat, the island has rebounded (risen in elevation) and new beach areas have emerged, streams and lakes have formed, and trees and other vegetation have colonized the new territory. This image of Akimiski Island was captured by the Landsat 7 satellite on August 9, 2000.

Cloudless skies allowed a clear view of Tibet in mid-December 2008. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard NASA's Terra satellite captured this true-color, image on December 18, 2008. Snow caps some mountain peaks, and ice partially covers some lakes in this high-altitude region, nicknamed the "Roof of the World."

The Bear Glacier on the Kenai Peninsula along the Gulf of Alaska seen by the IKONOS satellite took this on August 8, 2005. This image shows the ablation zone where the glacier is primarily losing ice. Upslope from the lake, the foot of the glacier is riddled with crevasses - cracks in the ice caused by the glacier's movement over a rough surface. Down the middle of the glacier run dark gray stripes. As a glacier moves, it picks up dirt and

Mountainous countryside near Maelifellssandur, Iceland. Once the young lava fields of Iceland cool down, life begins anew little by little. Ice, wind and water flatten and carve out shapes to begin with, then, during the summer, bacteria, lichen and fungi prepare the soil for plants, in particular mosses which adapt to an environment which remains difficult. These plants colonise the most favourable sites and terrain little by little, forming a
