Glacial Melt Minimal Effect On Sea Level
2013-08-13 09:47:09

Once thought to be a major contributor to sea-level rise, a new study indicates glacial melt water was found to have only a minor effect on sea levels.

Greenland Ice Sheet Is Melting From Below
2013-08-12 04:20:03

High heat flow from the mantle into the lithosphere is causing the Greenland ice sheet to melt from below, according to new research published in Sunday’s online edition of the journal Nature Geoscience.

Wildlife Greatly Impacted By Arctic Sea-Ice Loss
2013-08-02 07:11:40

Because sea ice is at its lowest point in 1,500 years, scientists are questioning how ecological communities in the Arctic will be affected by this continued and perhaps accelerating melting process over the next two decades.

Polar Pool Not Extreme
2013-07-31 11:23:48

Last week's pictures from the North Pole Experimental Observatory showed pools of polar sea water, but experts say they aren't "particularly extreme."

Arctic Winters Were Ice-Free Three To Five Million Years Ago
2013-07-30 06:29:43

During the Pliocene Epoch, the Earth was substantially warmer than it is today, despite similar concentrations of carbon dioxide in the atmosphere. A new study, led by the University of Colorado Boulder, suggests year-round ice-free conditions across the surface of the Arctic Ocean could explain the difference.

Antarctic Permafrost Melting Faster Than Previously Thought
2013-07-24 17:51:21

Scientists reported in the journal Scientific Reports that permafrost in a section of Antarctica is melting faster than expected.

Study Explains Surprising Acceleration Of Greenland's Inland Ice
2013-07-24 14:49:30

Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, a new NASA-funded study finds.

Glacier Geometry Linked To Diverse Calving Patterns
2013-07-23 05:24:37

Large stretches of ice on the coasts of Antarctica and Greenland are at risk of rapidly cracking apart and falling into the ocean in events over the coming decades that could aggravate sea level rise.

Columbia Plateau
2013-04-19 16:35:47

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....

Arctic Ocean
2013-04-18 22:31:23

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
2009-07-06 17:15:30

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...
