WASHINGTON, July 24, 2014 /PRNewswire-USNewswire/ -- A new study by NASA and University of California, Irvine, scientists finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought. http://photos.prnewswire.com/prnvar/20081007/38461LOGO This study is the first to quantify the...

NASA Scientists Use GPS To Find Sierra Water Weight
2014-05-11 03:18:48

Carol Rasmussen, NASA's Jet Propulsion Laboratory For the first time, NASA scientists have used GPS to find the total weight of winter snowpack and soil moisture in California's Sierra Nevada. The new results complement other satellite measurements and could provide a reality check for computer models used to estimate the state's water and snowpack. A team led by Donald Argus of NASA's Jet Propulsion Laboratory, Pasadena, Calif., studied data from 1,069 GPS research sites in...

WASHINGTON, Feb. 25, 2014 /PRNewswire-USNewswire/ -- NASA is partnering with the California Department of Water Resources (DWR) to develop and apply new technology and products to better manage and monitor the state's water resources and respond to its ongoing drought. http://photos.prnewswire.com/prnvar/20081007/38461LOGO NASA scientists, DWR water managers, university researchers and other state resource management agencies will collaborate to apply advanced remote sensing and...

NASA Satellites Show Middle East Water Loss
2013-02-12 19:10:45

Lee Rannals for redOrbit.com — Your Universe Online Scientists are reporting in the journal Water Resources Research the Middle East river basin is losing large quantities of water. The researchers used a pair of gravity-measuring NASA satellites to find that during a seven-year period, parts of Turkey, Syria, Iraq and Iran along the Tigris and Euphrates river basin have lost 117 million acre feet of freshwater, which is about the equivalent to the Dead Sea. Using NASA's twin...

Southern Patagonian Icefield Melting Fast
2012-09-06 07:04:10

April Flowers for redOrbit.com - Your Universe Online Much has been said lately about Arctic ice melting at an alarming and record-breaking rate, but other ice fields are suffering the same effects of global warming as well. For the last 40 years, scientists have monitored the growing and shrinking of the ice fields in the southern most stretch of South America's Andes Mountains, detecting an overall ice loss as the climate warms. A new study, published in the September 5 issue of...

How much ice is Greenland is really losing? - Movement in the Earth's mantle? - Enough water for all? For the first time, the melting of glaciers in Greenland could now be measured with high accuracy from space. Just in time for the tenth anniversary of the twin satellites GRACE (Gravity Recovery and Climate Experiment) a sharp image has surface, which also renders the spatial distribution of the glacial melt more precisely. The Greenland ice shield had to cope with up to 240 gigatons of...

Researchers Taking Stock Of Earth's Melting Ice
2012-02-09 10:36:22

[ Watch the Video ] In a new study led by researchers at the University of Colorado at Boulder, scientists using NASA data have found that Earth´s glaciers and ice caps outside of the regions of Greenland and Antarctica are losing nearly 150 billion tons of ice annually. Using satellite measurements from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (GRACE), researchers were able to measure ice loss in all of Earth´s land ice between 2003 and 2010....

Grace Mission Helps Monitor Drought In the US

The record-breaking drought in Texas that has fueled wildfires, decimated crops and forced cattle sales has also reduced groundwater levels in much of the state to the lowest levels in more than 60 years, according to new national maps produced by NASA using data from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (Grace) mission. The map are distributed by the National Drought Mitigation Center at the University of Nebraska-Lincoln. The latest groundwater map,...

NASA has put to rest any speculations that Earth maybe expanding or contracting. New research has found that there has been no statistically significant expansion of the solid Earth. Tectonic forces like earthquakes and volcanoes push mountains higher, while erosion and landslides wear them down, helping to change the Earth's shape. However, despite the facelift, this new research - using space measurement tools and a new data calculation technique - says Earth's size will remain the same....
