Michael Harper for redOrbit.com – Your Universe Online A group of Canadian researchers says they’ve finally figured out why icicles grow with those characteristic ripples. The answer, they say, is the amount of impurities in the water, particularly salt. Experimental physicist Stephen Morris and PhD candidate Antony Szu-Han Chen say they were intrigued by the way ripples consistently grow on icicles, regardless of geographic location or how large the spear becomes. After growing 67...

Channels In Antarctic Ice Shelf Will Help Predict Future Of Antarctic Ice
2013-10-07 04:31:47

redOrbit Staff & Wire Reports - Your Universe Online The discovery of hundreds of kilometers worth of channels beneath a floating ice shelf in Antarctica could help experts understand how the ice will respond to changes in environmental conditions, according to a study published Sunday in the journal Nature Geoscience. Researchers from the University of Exeter, Newcastle University, the University of Bristol, the University of Edinburgh, the British Antarctic Survey and the...

Climate Change May Be Indirectly Threatening Caribou In The Arctic
2013-10-01 14:04:59

Lee Rannals for redOrbit.com - Your Universe Online New research indicates that caribou may be indirectly affected by climate change due to sea-ice loss in the Arctic. Researchers, publishing a paper in the journal Nature Communications, say that melting sea ice is leading to fewer caribou calf births and higher calf mortality in Greenland. The team was able to link the melting Arctic sea ice with changes in the timing of plant growth on land, which in turn led to lower production of...

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...

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
