Swamp-Like Water System Revealed Under Antarctica's Thwaites Glacier
2013-07-09 14:43:50

Lee Rannals for redOrbit.com - Your Universe Online While using an innovative radar analysis method to accurately image the sub-glacial water system under West Antarctica's Thwaites Galcier, scientists discovered a swamp-like canal system beneath the ice. The scientists, from The University of Texas at Austin's Institute for Geophysics, reported in the Proceedings of the National Academy of Sciences (PNAS) that the swamp-like canal is several times as large as Florida's Everglades....

First Greenland Test Passed By NASA’s Polar Robotic Ranger
2013-07-08 14:30:21

NASA [ Watch The Video GROVER Passes Tests In Greenland ] Defying 30 mph gusts and temperatures down to minus 22 F, NASA's new polar rover recently demonstrated in Greenland that it could operate completely autonomously in one of Earth's harshest environments. The robot known as GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, was designed by teams of students attending engineering boot camps at Goddard in the summers...

Ghost Lake Found Beneath Antarctica's Ice Sheet
2013-07-03 05:32:53

April Flowers for redOrbit.com - Your Universe Online A vast crater has been found in Antarctica's icy surface by the European Space Agency's (ESA) CryoSat satellite. The crater was formed, scientists believe, when a lake lying under about 2 miles of ice drained suddenly. There are lakes of fresh water trapped without a connection to the ocean, deep below the thick ice sheet that covers Antarctica. Scientists who are trying to understand water transport and ice dynamics beneath the...

Greenland Ice Sheet Had Record Melt In 2012 Due To Jet Stream
2013-06-17 13:50:43

Lee Rannals for redOrbit.com — Your Universe Online According to University of Sheffield research, published in the International Journal of Climatology, unusual Jet Stream changes were behind record surface melt of the Greenland Ice Sheet last summer. The Greenland Ice Sheet (GrIS) experienced a record surface melting in the summer of 2012, with more than 90 percent of the ice-sheet surface melting as of July 11, 2012. That was nearly double the previous record loss seen in 2010,...

Basal Melt Responsible For Antarctic Ice Shelf Loss
2013-06-14 06:20:18

redOrbit Staff & Wire Reports - Your Universe Online The majority of Antarctica´s ice loss is caused by warm ocean waters eating away at the undersides of ice shelves, not the sudden release and breaking away of ice masses from glaciers (a process known as calving), according to new research appearing in Friday´s edition of the journal Science. In what is being called “the first comprehensive survey of all Antarctic ice shelves,” researchers from the University...

NASA's Operation IceBridge Mission Contributes To New Map Of Antarctica
2013-06-06 09:26:57

NASA A new dataset called Bedmap2 gives a clearer picture of Antarctica from the ice surface down to the bedrock below. Bedmap2 is a significant improvement on the previous collection of Antarctic data–known as Bedmap–that was produced more than 10 years ago. The product was a result of work led by the British Antarctic Survey, where researchers compiled decades worth of geophysical measurements, such as surface elevation measurements from NASA's Ice, Cloud and Land Elevation...

Ice Age Did Not Stop The Arctic Current From Flowing
2013-05-30 05:30:24

April Flowers for redOrbit.com - Your Universe Online When thick ice covered the Arctic during the last ice age, many scientists assumed that the deep currents below the ice that feed the North Atlantic Ocean and help drive the global ocean currents slowed or possibly even stopped. A new study reveals that the deep Arctic Ocean has been churning briskly for the last 35,000 years, through the chill of the last ice age and warmth of modern times. These findings, published in the journal...

Researchers Map New Jersey Sea-Level Changes Over Last 10,000 Years
2013-05-29 09:07:40

April Flowers for redOrbit.com - Your Universe Online The public and policymakers alike were caught off guard when Hurricane Sandy hit the east coast of the US last fall. The majority of the destruction came from the storm surge and flooding that followed the storm, leading researchers to pay attention to how climate change and sea-level rise may have played a role in the disaster, and how those same factors may impact the shoreline in the future. Benjamin P. Horton, an associate...

There is growing recognition that reductions in Arctic sea ice levels will influence patterns of atmospheric circulation both within and beyond the Arctic. New research in the International Journal of Climatology explores the impact of 2007 ice conditions, the second lowest Arctic sea ice extent in the satellite era, on atmospheric circulation and surface temperatures. Two 30-year simulations, one using the sea ice levels of 2007 and another using sea ice levels at the end of the 20th...

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...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
