NASA Mission Detects Significant Antarctic Ice Mass Loss

The researchers
found Antarctica's ice sheet decreased by 152 (plus or minus 80 ) cubic
kilometers of ice annually between April 2002 and August 2005.
That is about how much water the United States consumes in three months (a
cubic kilometer is one trillion liters; approximately 264 billion gallons of
water).

They demonstrated for the first time that
Antarctica's ice sheet lost a significant amount of mass since the launch of
GRACE in 2002.2 millimeters (0. Most of the mass loss came from the West
Antarctic ice sheet.

projections of sea level change, this represents a very important step toward
more accurate prediction, and has important societal and economic impacts.nasa.

National Geographic has funded nearly 8,000 scientific research
projects and supports an education program combating geographic
illiteracy.
The Antarctic mass loss findings were enabled by the ability of the
identical twin GRACE satellites to track minute changes in Earth's gravity
field resulting from regional changes in planet mass distribution.gov/home

Even studies that synthesized results from several techniques,
such as the assessment by the Intergovernmental Panel on Climate Change,
suffered from a lack of data in critical regions.

Plum Creek will have a booth at the event so that students can
interact with foresters, wildlife biologists, and others whose job it
is to care for the wide range of wildlife , fish and plant species that
live on Plum Creek's 8 million acres of timberland in the United
States . It reaches more than 280 million people worldwide each month

"Combining GRACE data with data from other instruments such as NASA's Ice
Cloud and land Elevation Satellite, radar and altimeters that are more
effective for studying individual glaciers is expected to substantially
improve our understanding of the processes controlling ice sheet mass
variations," Velicogna said.

National Geographic Live! Spring 2005 education program, created in
collaboration with the Woodland Park Zoo and made possible by Plum
Creek, will be held at Benaroya Hall between February 23 and May 16.
"Through Plum Creek's generous support we are pleased to offer
these special events to local area schools.
The student events will captivate grade school and high school
students as they catch a glimpse into the adventures of a renowned
photojournalist who has captured images of exotic wildlife; a daring
Norwegian adventurer who has completed a grueling 325-mile journey
across the Southern Patagonia Ice Field, and much more. If you are interested in registering for this event , call

Seattle students will be educated and entertained as they listen and
learn about the global expeditions of five diverse explorers.
Plum Creek is one of the largest private timberland owners in the
nation, with approximately 8 million acres of timberlands in major
timber producing regions of the United States and 10 wood products

The company will also distribute seedlings to students. WASHINGTON, Scientists were able to conduct the
first-ever gravity survey of the entire Antarctic ice sheet using data from
the joint NASA/German Aerospace Center Gravity Recovery and Climate Experiment
(GRACE). GRACE is able to overcome these issues, surveying
the entire ice sheet, and tracking the balance between mass changes in the
interior and coastal areas .
