Reindeer and Snowflakes: NASA Helps During International Polar Year

3/28/2007 Two things that come to mind during wintertime are snowflakes and reindeer. Now, NASA is providing technology to help study both of those in various ways during a kick off of the International Polar Year in Norway. More

Gravity Measurements Help Melt Ice Mysteries

3/23/2007 Just a few years ago, the world's climate scientists predicted that Greenland wouldn't have much impact on sea level in the coming decades. But recent measurements show that Greenland's ice cap is melting much faster than expected. These new data come from the NASA/German Aerospace Center's Gravity Recovery and Climate Experiment (GRACE). More

Glacial Earthquakes Point to Rising Temperatures in Greenland

3/23/2007 Scientists have found a new indicator that the Earth is warming: "glacial earthquakes" caused when the rivers of ice lurch unexpectedly. Glacial earthquakes in Greenland have doubled since 2002. More

'Cool' Science: JPL Observes International Polar Year

3/21/2007 Scientists at NASA's Jet Propulsion Laboratory have joined colleagues from other NASA centers, U.S. agencies and universities, as well as more than 60 other nations, in a worldwide campaign to better understand the polar regions of Earth. Feature includes video interviews with JPL scientists. More

NOAA's State of the Arctic Report

3/18/2007 NOAA's “State of the Arctic” is a review of environmental conditions during the past five years, relative to those in the latter part of the 20th century. It was conducted by an international group of 20 scientists who developed a consensus on content and reliability. More

Preserving The Last Great Place: NOAA’s Ecosystem Approach to Studying the Antarctic

3/17/2007 The Antarctic Marine Living Resources research program is part of the NOAA Fisheries Southwest Fisheries Science Center, which collects the scientific information necessary to protect and manage resources in the Pacific and the Antarctic. More

Penguins as a Climate Bellwether

3/16/2007 Thanks to extensive field research and records contained in deposits of their bones accumulated over 30,000 years, scientists know more about how penguins will adjust to rapid climate change than almost any other creature on Earth. More

NOAA Plane Braves Winter Weather to Verify Satellite Wind Measurements

3/15/2007 A NOAA "hurricane hunter" aircraft earlier this month wrapped up a mission in St. John's, Newfoundland, Canada, to acquire wind and precipitation data over the ocean in severe weather that will be used to improve marine weather forecasts. More

Fact Sheet: Smithsonian Polar Research

3/15/2007 From the cultural heritage studies of the Arctic Studies Center to South Pole telescopes to curation of Antarctic meteorites to polar biology research at the Smithsonian Environmental Research Center, a compendium of polar science. More

A Dinosaur Find in Antarctica

3/14/2007 William Hammer, an NSF-funded researcher at Augustana College, discovered the remains of Cryolophosaurus ellioti in 1991, proving that dinosaurs lived on every continent. In a 2003 Webcast, he described the find and the beast. More
