An outlet glacier
located in the northeast part of Greenland has declined 12.
The model will be applied to the Pine Island Glacier (PIG), an important outlet glacier
draining a portion of the WAIS, which has been studied extensively and is currently thinning at an increasing rate.
Melt water lubricates the base of glaciers that carry ice from the interior to the sea, causing their movement to accelerate--for instance, the speed of Greenland's largest outlet glacier
doubled in just five years.
The findings use new observational techniques to address long-standing questions about subglacial water under Thwaites, a Florida-sized outlet glacier
in the Amundsen Sea Embayment considered a key factor in projections of global sea level rise.
Jakobshavn is the largest outlet glacier
in Greenland and drains 6.
After sampling and analyzing the outflow from below the Taylor Glacier, an outlet glacier
of the East Antarctic Ice Sheet in the otherwise ice-free McMurdo Dry Valleys of Antarctica, researchers believe that, lacking enough light to make food through photosynthesis, the microbes have adapted over the past 1.
Recent measurements have also shown that the outlet glaciers
that drain the Greenland and West Antarctic Ice Sheets are thinning and retreating.
A team from Durham University's Department of Geography used declassified spy satellite imagery to create the first long-term record of changes in the terminus of outlet glaciers
- where they meet the sea - along 5,400km of the East Antarctic Ice Sheet's coastline.
Glaciological studies of two outlet glaciers
, northwest Greenland, 1953.
In Criscitiello's study area, two large outlet glaciers
emptying into Pine Island Bay--the Pine Island and Thwaites Glaciers--have been accelerating and losing mass over the past 25 years.
To better understand and forecast such effects, researchers are targeting a few key outlet glaciers
, which funnel ice from the high frozen interior into the oceans.
High- and low-altitude flights also will survey Greenland's ice sheet and outlet glaciers
