Lake Towuti
2014-03-25 12:05:49

Brown University Using sediments from a remote lake, researchers from Brown University have assembled a 60,000-year record of rainfall in central Indonesia. The analysis reveals important new details about the climate history of a region that wields a substantial influence on the global climate as a whole. The Indonesian archipelago sits in the Indo-Pacific Warm Pool, an expanse of ocean that supplies a sizable fraction of the water vapor in Earth's atmosphere and plays a role in...

Moss Still Lives After 1500 Years Buried In Antarctic Ice
2014-03-17 14:57:18

Brett Smith for redOrbit.com - Your Universe Online British researchers who typically study polar moss samples because they provide indications of past climate conditions have found that Antarctic moss can survive trapped under ice for over 1,500 years. While some plant material has been brought back to life after 20 years of being frozen, only microbes have been shown to be capable of thousand-year feats of revival; that is until now. "These mosses were basically in a very long-term...

Greenland Ice Sheet Receding And Is Now Considered Unstable
2014-03-17 10:26:10

Brett Smith for redOrbit.com - Your Universe Online According to a new report in the journal Nature Climate Change, the last stable section of the Greenland ice sheet is receding and now considered unstable – a development that could portend even more ice loss in the future and significant sea level rise. The report focused on a key ice stream in the Greenland ice sheet. Ice streams drain an ice basin from the interior of the sheet, in the same way that regular streams drain water...

Unraveling Mystery Of Retreating Glaciers In The Pacific Ocean's Western Tropics
2014-03-14 11:39:06

University of California - Los Angeles Using a cutting-edge research technique, UCLA researchers have reconstructed the temperature history of a region that plays a major role in determining climate around the world. The findings, published online Feb. 27 in the journal Nature Geoscience, will help inform scientists about the processes influencing global warming in the western tropical Pacific Ocean. The study analyzes how much temperatures have increased in the region near...

redOrbit Staff & Wire Reports - Your Universe Online Scientists working on NASA’s Operation IceBridge mission are en route to Greenland to kick off this year’s Arctic land and sea ice data collection efforts, officials from the US space agency announced on Wednesday. On Monday, the researchers departed from the Wallops Flight Facility in Wallops Island, Virginia on board the agency’s P-3 research aircraft. They will be collecting and reporting valuable information on rapidly...

WASHINGTON, March 12, 2014 /PRNewswire-USNewswire/ -- Researchers aboard NASA's P-3 research aircraft left the agency's Wallops Flight Facility in Wallops Island, Va., March 10 for Greenland to begin a new season of collecting data on Arctic land and sea ice. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The mission, known as Operation IceBridge, is to gather data on changes to polar ice and maintain continuity of measurements between NASA's Ice, Cloud and Land Elevation...

Greenland Jakobshavn Glacier
2014-03-12 04:40:59

Lee Rannals for redOrbit.com - Your Universe Online New data obtained by NASA's Operation IceBridge program is shedding new light on how ice sheets in Greenland are changing. Scientists used satellite observations and ice thickness measurements made by Operation IceBridge to determine the rate at which ice flows through Greenland’s glaciers into the ocean. The findings have shown how glacier flow is affecting the Greenland Ice Sheet and that this process is being dominated by a small...

Warm Rivers Play A Role In Arctic Sea Ice Melt
2014-03-06 06:32:21

Brett Smith for redOrbit.com - Your Universe Online According to a new study from NASA researchers, warm river waters draining into the Arctic Ocean are adding to the melting of sea ice in the Arctic Ocean each summer. Published in the journal Geophysical Research Letters, researchers reported on an abrupt inflow of warm river water into the Arctic Ocean that swiftly warmed the top layers in the sea, fueling the melting of summer ice. “River discharge is a key factor contributing...

Arctic Sea Ice Trends
2014-03-05 08:10:23

April Flowers for redOrbit.com - Your Universe Online According to new research from the University College London, the melt season across the Arctic is getting longer by five days every ten years. Julienne Stroeve, Professor of Polar Observation and Modeling at UCL Earth Sciences, led the team in analyzing satellite data. The analysis, published in Geophysical Research Letters, revealed that the Arctic Ocean is absorbing even more of the sun’s energy in summer, leading to an even...

Antarctic ice shelf
2014-03-03 05:04:27

McGill University In the mid-1970s, the first available satellite images of Antarctica during the polar winter revealed a huge ice-free region within the ice pack of the Weddell Sea. This ice-free region, or polynya, stayed open for three full winters before it closed. Subsequent research showed that the opening was maintained as relatively warm waters churned upward from kilometers below the ocean's surface and released heat from the ocean's deepest reaches. But the polynya -- which...

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...

endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
