Pleistocene Ice Sheet Evidence Uncovered
2013-10-01 04:53:02

April Flowers for redOrbit.com - Your Universe Online Traces of large ice sheets from the Pleistocene on a seamount off the north-eastern coast of Russia have been discovered by a team of geologists and geophysicists from the Alfred Wegener Institute (AWI) Helmholtz Centre for Polar and Marine Research. For the first time, these traces confirm that within the last 800,000 years in the course of ice ages, ice sheets more than approximately a mile thick also formed in the Arctic Ocean....

Deep-sea Core From Okinawa Trough Gives 200,000-year Environmental History Of Continental Shelf
2013-09-26 09:38:37

Science China Press A new research paper shows that a great number of nearby terrigenous pollen and charcoal have been found from the deep-sea sediments of the last 200 kyrs in Okinawa Trough. It is tesitfied that the continental shelf of the East China Sea was exposed and covered with the huge wetland and grassland ecosystems during the the last two glacial periods. They discovered that the variation of terrestrial sources is concordent with global glacial volume and sea-level changes at...

While we grapple with the impact of climate change, archaeologists suggest we spare a thought for Aboriginal Australians who had to cope with the last ice age. "The period scientists call the Last Glacial Maximum, or LGM for short, is the most significant climatic event ever faced by humans on this continent," Associate Professor Sean Ulm from James Cook University in Cairns said. Research recently published in the Journal of Archaeological Science sheds new light on the ways Aboriginal...

Arctic Sea Ice Minimum For 2013 Sixth Lowest On Record
2013-09-23 07:44:57

[ Watch The Video: 2013 Arctic Sea Ice Minimum Animation ] NASA After an unusually cold summer in the northernmost latitudes, Arctic sea ice appears to have reached its annual minimum summer extent for 2013 on Sept. 13, the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder has reported. Analysis of satellite data by NSIDC and NASA showed that the sea ice extent shrunk to 1.97 million square miles (5.10 million square kilometers). This...

Antarctic Glacier Rapidly Melting
2013-09-19 12:50:41

Michael Harper for redOrbit.com - Your Universe Online When it comes to predicting the effects of global warming on our environment, scientists look to the world’s glaciers, exceptionally large masses of ice which are melting into the sea. Now researchers from the University of Alaska Fairbanks say they've completed a thorough examination of these melting glaciers to get a better picture of how climate change is affecting Earth. Specifically, the researchers examined the ice melt from...

Global Warming Could Explain Exponential Sea Ice Growth
2013-09-18 12:28:55

Michael Harper for redOrbit.com - Your Universe Online In a bit of strange and unprecedented good news, it was recently discovered Antarctic sea ice is growing at record rates. This is definitely odd, of course, because the air and the oceans have been getting warmer in the area. There is now more sea ice in Antarctica than there had been in the 1970s, a data point which University of Washington (UW) researcher Jinlun Zhang wanted to unpack and investigate. According to his National...

New research has revealed that more ice leaves Antarctica by melting from the underside of submerged ice shelves than was previously thought, accounting for as much as 90 per cent of ice loss in some areas. Iceberg production and melting causes 2,800 cubic kilometers of ice to leave the Antarctic ice sheet every year. Most of this is replaced by snowfall but any imbalance contributes to a change in global sea level. For many decades, experts have believed that the most important process...

Pine Island Glacier Is Melting From Below
2013-09-13 04:27:05

[ Watch the Video: Warm Ocean Melting Pine Island Glacier ] redOrbit Staff & Wire Reports - Your Universe Online The floating ice shelf in a remote region of Antarctica is being melted by warm ocean water, not hot air, an international team of researchers report in the latest edition of the journal Science. As described in the new study, an expedition to Pine Island Glacier allowed scientists to get an up-close-and-personal look beneath the ice of one of the most difficult 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...
