Arctic Ice Cover Continues To Shrink
2013-04-04 08:52:02

[ Watch the Video: An Interesting Year for Arctic Sea Ice ] April Flowers for redOrbit.com - Your Universe Online The Arctic Ocean's ice cover shrank to its lowest extent on record last September at the end of the northern hemisphere summer. This continues a long-term trend diminishing the ice to about half the size of the average summertime extent from 1979 to 2000. The sea ice refreezes during the cold and dark Arctic winter, achieving its maximum extent usually in late February or...

Warming Oceans May Be Driving Sea-Ice Expansion In Antarctica
2013-04-01 07:07:28

Lawrence LeBlond for redOrbit.com - Your Universe Online A growing number of studies have pegged global warming and climate change as a cause of sea-ice decline in recent decades. However, a newly published study in the journal Nature Geoscience is showing a vastly different scenario. According to researchers at the Royal Netherlands Meteorological Institute (KNMI), ocean warming may actually be driving sea-ice expansion in the Antarctic. While sea ice at the North Pole has shrunk...

Loss Of Arctic Ice May Be Cause Of This Chilly Spring
2013-03-27 14:31:07

Brett Smith for redOrbit.com - Your Universe Online Have you been experiencing the coldest spring weather in recent memory? It´s probably because of global warming. According to climate scientists, warmer than average temperatures have thrown a monkey wrench into global weather patterns by melting Arctic sea ice at record rates during the summer months. "Ironically ... as the ice pack retreats and the Arctic heats up, there's a counteracting tendency in middle latitudes for colder...

NASA Operation IceBridge 2013 Getting Ready For New Season
2013-03-21 19:01:30

Lee Rannals for redOrbit.com — Your Universe Online NASA has kickstarted another season of science flights over Greenland to perform research activity with Arctic ice sheets and sea ice. Operation IceBridge scientists will be flying a specially equipped P-3B research aircraft from NASA's Wallops Flight Facility in Virginia to carry out land and sea ice surveys in and around Greenland and the Arctic Ocean through early May. NASA started the Operation IceBridge campaign in 2009...

Climate Change Affecting Polar Bears, Only Those With The Most Fat Thrive
2013-03-20 14:36:52

Brett Smith for redOrbit.com - Your Universe Online Recent climate induced changes to Arctic polar bears´ environment is affecting their habits and ability to survive, with the bears having to rely more and more on internal fat reserves, according to a new paper in the Journal of Animal Ecology. The bears are having particular difficulty adjusting to the shifting sea ice dynamics. In the past, sea ice has remained throughout the Arctic summer months, but now it is almost...

Greenland's Peripheral Glaciers Also Contribute Significantly To Sea-Level Rise
2013-03-18 13:39:33

Alan McStravick for redOrbit.com - Your Universe Online The oft-cliché idea behind the naming of Iceland and Greenland claims their names were derived in an attempt to fool would be sailing marauders, attracting them to the desolate but more hospitably named Greenland, leaving the citizens of Iceland to live upon their slightly more lush island without threat of invasion. In fact, Erik the Red, it is believed, gave the moniker to attract settlers to the ice covered island...

Significant Iron Contributed To North Atlantic Ocean By Glaciers
2013-03-11 12:23:52

Woods Hole Oceanographic Institution All living organisms rely on iron as an essential nutrient. In the ocean, iron´s abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the ocean´s food web. A new study by biogeochemists and glaciologists at Woods Hole Oceanographic Institution (WHOI) identifies an unexpectedly large source of iron to the North Atlantic — meltwater from glaciers and ice sheets, which may stimulate plankton...

The Forming Of Antarctica's Hidden Fjords
2013-03-06 13:41:41

University of Arizona Antarctica's topography began changing from flat to fjord-filled starting about 34 million years ago, according to a new report from a University of Arizona-led team of geoscientists. Knowing when Antarctica's topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise. Although radar surveys have revealed a rugged alpine landscape...

Research Provides New Insight Into Snowball Earth Duration
2013-02-28 21:17:15

Lee Rannals for redOrbit.com — Your Universe Online About 635 million years ago, our world was covered in ice during an event called "Snowball Earth," and new details written in the Proceedings of the National Academy of Sciences provide new insight on the duration of this event. According to the Snowball Earth hypothesis, an ice age brought on rapid changes in the atmospheric conditions on our planet, followed by a rapid greenhouse heat wave. This period may have given rise to...

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...
