Current changes in the ocean around Antarctica are disturbingly close to conditions 14,000 years ago that new research shows may have led to the rapid melting of Antarctic ice and an abrupt 3-4 meter rise in global sea level.
A dense mass of Pacific walruses, estimated to be 35,000 strong, has gathered on a beach in northwest Alaska, approximately five miles north of Point Lay. Scientists believe this unprecedented number of animals has been driven to shore by a lack of sea ice.
Thanks in part to support from NASA and the National Science Foundation, scientists have produced the first-ever detailed maps of bedrock beneath glaciers in Greenland and Antarctica.
Prevailing models from the melting of the Greenland ice sheet have made the calculation that the ice sheet sits atop hard bedrock. A new study from a team of British and American scientists has thrown out that assumption, however.
Although not designed to map changes in Earth’s gravity over time, ESA’s extraordinary satellite has shown that the ice lost from West Antarctica over the last few years has left its signature.
Antarctic fish that manufacture their own "antifreeze" proteins to survive in the icy Southern Ocean also suffer an unfortunate side effect
New research has shown that sea ice removes CO2 from the atmosphere. If Arctic sea ice is reduced, we may therefore be facing an increase of atmospheric concentration of CO2, researchers warn.
2014 Arctic sea ice coverage is the sixth lowest recorded since 1978, researchers from the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado, Boulder revealed on Monday.
WASHINGTON, Sept. 22, 2014 /PRNewswire-USNewswire/ -- Arctic sea ice coverage continued its below-average trend this year as the ice declined to its annual minimum on Sept.
One of the most visible signs of climate change in recent years was not even visible at all until a few decades ago.
The Columbia Plateau ecoregion is a Level III ecoregion designed by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington, with little areas over the Washington state border in Idaho. This ecoregion stretches across a wide swath of the Columbia River Basin from the Dalles, Oregon to Lewiston, Idaho to Okanogan, Washington near the Canadian border. It incorporates nearly 500 miles of the Columbia River, as well as the lower reaches of major tributaries....
The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...
Meltwater is water that is released from melting snow or ice. This includes meltwater from glacial ice and ice shelves over oceans. Meltwater is often produced during volcanic eruptions, and can cause dangerous lahars (landslides of wet volcanic debris). When meltwater pools on the surface rather than draining or flowing away, it forms pools known as melt ponds. Meltwater will often refreeze as the temperature drops. Meltwater can also collect or melt under the ice's surface. Sub-glacial...
