Glaciers Cracking In Presence Of Carbon Dioxide
2012-10-11 19:48:46

Alan McStravick for redOrbit.com — Your Universe Online Our glaciers and ice caps are experiencing a little chemistry-based “good cop, bad cop” and it looks like the bad cop is going to make them crack under pressure. There is little doubt in the scientific community about the excessive presence at startling levels of carbon dioxide (CO2) in our atmosphere and the effect it is having on our increasing global temperatures and our melting ice caps and glaciers....

Polarstern Has News About Arctic Sea Ice
2012-10-11 18:43:41

Alan McStravick for redOrbit.com — Your Universe Online The Polarstern expedition has disconcerting news about our rapidly receding sea ice. The Polarstern, an ice-breaking research vessel, returned to the port of Bremerhaven two days ago. The Polarstern, operating on behalf of the Alfred Wegener Institute, was conducting research into the retreat of sea ice and the impact it will have on the Arctic Ocean and its ecosystems over the last two months. In all, 54 researchers and...

ESA Satellites Taking A Deeper Look Into Sea Ice
2012-10-05 08:28:31

This year, satellites saw the extent of Arctic sea ice hit a record low since measurements began in the 1970s. ESA´s SMOS and CryoSat satellites are now taking a deeper look by measuring the volume of the sea-ice cover. Measurements from ESA´s Soil Moisture and Ocean Salinity (SMOS) mission show that ice has thinned significantly in the seasonal ice zones, with extensive areas less than half a metre thick. Sea ice has a large influence on the heat exchange between the ocean...

Ice Core Lab Brings The Arctic To Denver Year Round
2012-10-02 05:01:20

[ Watch the Video: National Ice Core Lab Stores Valuable Ancient Ice ] Lee Rannals for redOrbit.com - Your Universe Online While temperatures across the country start to cool in accordance to the changing of seasons, there is one place in Denver, Colorado where it stays cool all year round. Colorado experienced record highs this summer, but the National Ice Core Laboratory (NICL) was one place in the state that stayed well below hot, at minus 10 degrees Fahrenheit. The...

Desert Climate In West US Affected By Ancient Water Cycle
2012-09-28 09:06:29

Alan McStravick for redOrbit.com - Your Universe Online The climate change we are currently experiencing, while disconcerting and increasingly uncomfortable, is not unprecedented when viewed through the historical prism of life on Earth. A study led by researchers from Texas A&M University's Department of Oceanography looks back at the water cycle that affected the Western United States in an era dating back some 20,000 years. Focusing on the deserts of  Utah and Nevada,...

Youth Therapy For Scandinavia's Glaciers And Landscape
2012-09-24 11:45:58

The high elevation flat surfaces characteristic of the Norwegian landscape are in geologically terms young, according to a paper in Nature Geoscience. In a paper recently published in Nature Geoscience, researchers from the University of Bergen (UiB) and ETH Zurich have demonstrated that ice sheets have extensively shaped the fjords of Norway for the last 2.8 million years. — However, the massive sediment record deposited offshore Norway during this period tells us a more complex...

Arctic Ice Reaches Least Extent Since 2007 Summer Season
2012-09-20 09:23:03

Lawrence LeBlond for redOrbit.com - Your Universe Online The Arctic sea ice has stopped receding this year, but not before reaching its smallest extent, breaking the previous record set in the summer of 2007, by 18 percent. The new low sets the summertime ice area extent to about 2.1 million square miles, according to estimates from the US National Snow and Ice Data Center (NSIDC) in Colorado. This year´s unprecedented ice melt in the Arctic is the clearest sign yet of global...

Eltanin meteor
2012-09-20 04:27:37

April Flowers for redOrbit.com - Your Universe Online Around 2.5 million years ago, a huge meteor collided with the Earth and fell into the southern Pacific Ocean. A new study, published in the Journal of Quaternary Science, suggests that not only could this have caused a massive tsunami, but it may also have plunged the world into the Ice Ages. A research team from Australia says that because the Eltanin meteor — which was up to two kilometers across — crashed into deep...

Antarctic Ice Facing Changes By Fast-Flowing Glaciers
2012-09-19 14:14:23

Lee Rannals for redOrbit.com — Your Universe Online A new study found that fast-flowing and narrow glaciers could trigger massive changes in the Antarctic ice sheet, inevitably adding sea-level rise and ice-sheet decay. The team tested high-resolution model simulations against reconstructions of the Antarctic ice sheet from 20,000 years ago. Writing in the journal Proceedings of the National Academy of Sciences (PNAS), they said they used a new model during their study, capable...

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...

penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
