NASA Scientists Watching, Studying Arctic Changes This Summer

Patrick Lynch, NASA’s Earth Science News Team As we near the final month of summer in the Northern Hemisphere, NASA scientists are watching the annual seasonal melting of the Arctic sea ice cover. The floating, frozen cap that stretches...

Human Contribution To Glacier Mass Loss Increasing
2014-08-18 03:43:32

University of Innsbruck By combining climate and glacier models, scientists headed by Ben Marzeion from the University of Innsbruck have found unambiguous evidence for anthropogenic glacier mass loss in recent decades. In a paper published in Science, the researchers report that about one quarter of the global glacier mass loss during the period of 1851 to 2010 is attributable to anthropogenic causes. The fraction of human contribution increased steadily and accelerated to almost two...

Potsdam Institute for Climate Impact Research Ice discharge from Antarctica could contribute up to 37 centimeters to the global sea level rise within this century, a new study shows. For the first time, an international team of scientists provide a comprehensive estimate on the full range of Antarctica’s potential contribution to global sea level rise based on physical computer simulations. Led by the Potsdam Institute for Climate Impact Research, the study combines a whole set of...

Snow on top of sea ice
2014-08-14 03:30:55

George Hale, NASA's Goddard Space Flight Center Over the past few decades, Arctic sea ice has been retreating, and although research shows a downward trend in snow on land in the Arctic, long-term measurements of snow depth on sea ice have been less clear. But now, new research using data from NASA's Operation IceBridge shows that snow depth on Arctic sea ice has been decreasing over the past several decades, a trend largely owing to later sea ice freeze-up dates in the Arctic. Arctic...

Finding Deepest Iceberg Scours To Date Provides New Insights Into Arctic’s Glacial Past
2014-08-13 03:02:09

Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have found between Greenland and Spitsbergen the scours left behind on the sea bed by gigantic icebergs. The five lineaments, at a depth of 1,200 meters, are the lowest-lying iceberg scours yet to be found on the Arctic sea floor. This finding provides new understanding of the dynamics of the Ice Age and the extent of...

Researchers Find Cooling Effect In Warming Arctic lakes
2014-08-07 03:47:42

University of Minnesota Scientists have known for a while that warming global temperatures are causing Arctic lakes to release methane, a potent greenhouse gas that leads to even more warming. In a new study published in the journal Nature, a team of researchers including U of M researcher Jacques Finlay, found that Siberian lakes have actually pulled more greenhouse gasses from the atmosphere than they have released into it since the last Ice Age, causing an overall slight cooling...

sea ice off alaska

Hannah Hickey, University of Washington As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water that is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell – huge waves that could add a new and unpredictable element to the region. A University of Washington researcher made the first study of waves in the middle of the...

antarctic sea ice extent

European Geosciences Union (EGU) New research suggests that Antarctic sea ice may not be expanding as fast as previously thought. A team of scientists say much of the increase measured for Southern Hemisphere sea ice could be due to a processing error in the satellite data. The findings were published July 22 in The Cryosphere, a journal of the European Geosciences Union (EGU). Arctic sea ice is retreating at a dramatic rate. In contrast, satellite observations suggest that sea ice...

Scientists Tracking Breakup Of Arctic Summer Sea Ice
2014-07-17 03:27:40

By Hannah Hickey, University of Washington As sea ice begins to melt back toward its late September minimum, it is being watched as never before. Scientists have put sensors on and under ice in the Beaufort Sea for an unprecedented campaign to monitor the summer melt. The international effort hopes to figure out the physics of the ice edge in order to better understand and predict open water in Arctic seas. "This has never been done at this level, over such a large area and for such...

Siberia Yamal Peninsula
2014-07-17 10:01:06

Joshua Garrett for redOrbit.com - Your Universe Online What could cause an 80 meter hole to form somewhere in northern Siberia? A meteorite strike? Aliens? Cthulhu? Researchers all over the world are scratching their heads over this one, as no one seems to have an answer they are 100 percent sure of. Reported by the Siberian Times, this giant hole of unknown depth appeared rather suddenly in the Yamal Peninsula, which is said to translate as “end of the world,” giving the whole...

West Antarctic Ice Sheet
2014-07-12 06:07:29

redOrbit Staff & Wire Reports - Your Universe Online Much of the climate change-related research published recently has focused on the impact of warming temperatures on the West Antarctic ice sheet – but what is it about this region that causes scientists to be so interested in it? According to the US National Oceanic and Atmospheric Administration (NOAA), the West Antarctic ice sheet contains two major slabs of frozen water (the Ronne and Ross Ice Shelves), as well as several...

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.'
