Understanding The Mechanisms Of Supraglacial Lake Drainage
2013-07-17 11:03:06

Brett Smith for redOrbit.com - Your Universe Online Lakes often form on top of a glacier and drain onto the bedrock below, lubricating a glacier's movements as a result. A new study from an international group of researchers has found that the way these lakes drain can affect the velocity, extent and direction of a glacier's progress. Previous research has focused on the lubrication action of supraglacial lakes after they drain, but not on the draining mechanism itself. According to the...

Alaska´s melting glaciers remain one of the largest contributors to the world´s rising sea levels, say two University of Alaska Fairbanks geophysicists. UAF Geophysical Institute researchers Anthony Arendt and Regine Hock joined 14 scientists from 10 countries who combined data from field measurements and satellites to get the most complete global picture to date of glacier mass losses and their contribution to rising sea levels. “Sea level change is a pressing societal...

Warming Oceans May Be Driving Sea-Ice Expansion In Antarctica
2013-04-01 07:07:28

Lawrence LeBlond for redOrbit.com - Your Universe Online A growing number of studies have pegged global warming and climate change as a cause of sea-ice decline in recent decades. However, a newly published study in the journal Nature Geoscience is showing a vastly different scenario. According to researchers at the Royal Netherlands Meteorological Institute (KNMI), ocean warming may actually be driving sea-ice expansion in the Antarctic. While sea ice at the North Pole has shrunk...

Significant Iron Contributed To North Atlantic Ocean By Glaciers
2013-03-11 12:23:52

Woods Hole Oceanographic Institution All living organisms rely on iron as an essential nutrient. In the ocean, iron´s abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the ocean´s food web. A new study by biogeochemists and glaciologists at Woods Hole Oceanographic Institution (WHOI) identifies an unexpectedly large source of iron to the North Atlantic — meltwater from glaciers and ice sheets, which may stimulate plankton...

Dramatic Glacial Melting In Andes Blamed On Climate Change
2013-01-22 13:47:37

Alan McStravick for redOrbit.com - Your Universe Online Only four months ago and a continent away, researchers were looking into the varying degrees of ice accumulation and ablation within the Himalayan glacial system. In that report, published by the National Research Council (NRC), the team concluded that glacial melt could pose significant issues for the native populations that depend on the water runoff from these glaciers for their day-to-day lives. An international team of...

Glaciers Will Continue To Shrink Regardless Of Temperature
2012-11-16 15:50:50

Michael Harper for redOrbit.com — Your Universe Online The Himalayan glaciers are going to continue to shrink, no matter which way the temperatures go, according to new research published in the journal Geophysical Research Letters. Summer Rupper, a geology professor at Brigham Young University, has just returned from her research in the Bhutan region of the Himalayas and has reported findings that nearly 10% of these glaciers will disappear within the next 30 years. She also...

Glacial Melt Accelerates in Himalayan Mountains with Mixed Effects
2012-09-13 09:48:46

Alan McStravick for redOrbit.com - Your Universe Online A report, issued this week by the National Research Council (NRC) has concluded that glacial melt in the Eastern and Central Himalayas has accelerated at an alarming rate, while glaciers in the Western Himalayas may actually be growing. Researchers say that this trend could have both positive and negative consequences for local inhabitants and ecosystems. These massive glacier-capped mountains, often referred to as the water towers...

Greenland Summer Ice Melt Breaks Record Month Before Season Ends
2012-08-16 11:14:51

April Flowers for redOrbit.com - Your Universe Online The summer melting season in Greenland usually lasts from June when the first puddles of meltwater appear, to September when temperatures begin to cool again. Melting over the Greenland ice sheet shattered the seasonal record on August 8 this year — a full four weeks before the close of the melting season, reports Marco Tedesco, assistant professor of Earth and atmospheric sciences at The City College of New York. This year,...

After the fall of the Soviet Union twenty years ago, water distribution in Central Asia became a source of conflict. In areas where summer precipitation is low, glaciers play an important role when considering the quantity of available water. The Tien Shan region is a prime example; mountain glaciers in this region contribute significantly to the fresh water supply in the arid zones of Kyrgyzstan, Kazakhstan, Uzbekistan, Turkmenistan, and Northwestern China. Like Switzerland, Kyrgyzstan...

Greenland Slipping Away
2012-04-17 05:03:44

Massive releases of meltwater from surface lakes may be causing Greenland to slide ever faster into the ocean, according to a new study by the University of Colorado Boulder-based Cooperative Institute for Research in Environmental Sciences (CIRES). Researchers say these actions could increase sea-level rise, having a direct impact on coastal communities. “This is the first evidence that Greenland´s ℠supraglacial´ lakes have responded to recent increases in surface...

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...
