USGS: Scientists Sail Aug. 2 to Map the Arctic Seafloor and Define the Limits of the Continental Shelf

8/2/2010 American and Canadian scientists are mapping the Arctic seafloor and gathering data to help define the outer limits of the continental shelf. More

Researchers Observe Mile-long Chunk of Ice Calving off Greenland Glacier

7/9/2010 NASA-funded researchers monitoring Greenland's Jakobshavn Isbrae glacier report that a 7-square-kilometer (2.7 square-mile) section of the glacier broke up on July 6 and 7. The chunk is roughly one-eighth the size of Manhattan. More

Underwater Gliders May Change How Scientists Track Fish off Alaska

6/8/2010 Tracking fish across Alaska’s vast continental shelves can present a challenge to any scientist studying Alaska’s seas. Researchers at the University of Alaska Fairbanks have successfully tested a solution in the form of underwater gliders. More

NSF-, USGS-Funded Study: Arctic Ice at Low Point Compared to Recent Geologic History

6/7/2010 An international group of researchers has compiled the first comprehensive history of Arctic ice and concluded that less ice covers the Arctic today than at any time in recent geologic history. More

NSF, NASA-funded Study: Greenland Rapidly Rising as Ice Melt Continues

5/20/2010 scientists at the University of Miami say Greenland's ice is melting so quickly that the land underneath is rising at an accelerated pace. Some coastal areas are rising by nearly an inch annually and could increase to two inches annually by 2025. More

NASA IceBridge Mission Prepares for Study of Arctic Glaciers

3/18/2010 NASA's Operation IceBridge mission, the largest airborne survey ever flown of Earth's polar ice, kicks off its second year of study when NASA aircraft arrive in Greenland March 22. More

NOAA Launches "Arctic Future" Web site

3/16/2010 NOAA’s Pacific Marine Environmental Laboratory has launched a new Web site to help those interested in the Arctic learn more about the long-term effects of the loss of Arctic summer sea ice. More

USGS: Ice Shelves Disappearing on Antarctic Peninsula

2/22/2010 Ice shelves are retreating in the southern section of the Antarctic Peninsula due to climate change. This could result in glacier retreat and sea-level rise if warming continues, threatening coastal communities and low-lying islands worldwide. More

USGS: Based on Geologic Evidence, Arctic Could Face Warmer and Ice-Free Conditions

12/29/2009 There is more evidence that the Arctic could face seasonally ice-free conditions and much warmer temperatures in the future, accoridng to USGS scientists. More

UC Santa Cruz Study: Slow Changes to Earth Systems such as Ice Sheets Likely to Amplify Global Warming

12/20/2009 Researchers studying a period of high carbon dioxide levels and warm climate several million years ago have concluded that slow changes such as melting ice sheets amplified the initial warming caused by greenhouse gases. More
