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...

Greenland Could Be Affected By Warming Temperatures
2012-11-14 09:01:27

April Flowers for redOrbit.com - Your Universe Online There are almost as many global climate models as there are climate scientists. Even with all of these models, however, it's very difficult to pin down how warming temperatures globally will affect any specific region. A research team from The City College of New York and the University of Liege, Belgium, and supported by the National Science Foundation (NSF), have made the "global local" using the output of three global models and...

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,...

Extreme Melting On Greenland Ice Sheet Reported

Glacial Melt Cycle Could Become Self-Amplifying, Making it Difficult to Halt The Greenland ice sheet can experience extreme melting even when temperatures don´t hit record highs, according to a new analysis by Dr. Marco Tedesco, assistant professor in the Department of Earth and Atmospheric Sciences at The City College of New York.  His findings suggest that glaciers could undergo a self-amplifying cycle of melting and warming that would be difficult to halt. “We are...

Scientists reported on Friday that Greenland's icesheet shed a record amount of melted snow and ice in 2010. The study found that the 2010 runoff was twice the average annual loss in Greenland over the previous three decades, surpassing a record set in 2007. According to the paper, ice melt has now topped this benchmark every year since 1996. Greenland's icesheet could drive up ocean levels by about 23 feet if it melted, drowning coastal cities around the world. No credible projections...

High-Resolution Video, Photos Available Upon Request New York (Vocus/PRWEB) January 20, 2011 New research shows that 2010 set new records for the melting of the Greenland Ice Sheet, expected to be a major contributor to projected sea level rises in coming decades. "This past melt season was exceptional, with melting in some areas stretching up to 50 days longer than average," said Dr. Marco Tedesco, Director of the Cryosphere Processes Laboratory at the City College of New York (CCNY...

Marco Tedesco Says Record Low Resulted From Simultaneous Positive Phases for Two Climate Drivers The 30-year record low in Antarctic snowmelt that occurred during the 2008-09 austral summer was likely due to concurrent strong positive phases for two main climate drivers, ENSO (El Niño - Southern Oscillation) and SAM (Southern Hemisphere Annular Mode), according to Dr. Marco Tedesco, Assistant Professor of Earth & Atmospheric Sciences at The City College of New...

The northern part of the Greenland ice sheet experienced extreme snowmelt during the summer of 2008, with large portions of the area subject to record melting days, according to Dr. Marco Tedesco, Assistant Professor of Earth & Atmospheric Sciences at The City College of New York (CCNY), and colleagues.  Their conclusion is based on an analysis of microwave brightness temperature recorded by the Special Sensor Microwave Imager (SSM/I) onboard the F13 satellite. "Having such extreme...

A new NASA-supported study reports that 2007 marked an overall rise in the melting trend over the entire Greenland ice sheet and, remarkably, melting in high-altitude areas was greater than ever at 150 percent more than average. In fact, the amount of snow that has melted this year over Greenland could cover the surface size of the U.S. more than twice. Marco Tedesco, a research scientist at the Joint Center for Earth Systems Technology, cooperatively managed by NASA's Goddard Space Flight...

In 2006, Greenland experienced more days of melting snow and at higher altitudes than average over the past 18 years, according to a new NASA-funded project using satellite observations. Daily satellite observations have shown snow melting on Greenland's ice sheet over an increased number of days. The resulting data help scientists understand better the speed of glacier flow, how much water will pour from the ice sheet into the surrounding ocean and how much of the sun's radiation will...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
