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...

Study yields precise estimates of tectonic plate movements When it comes to three-dimensional puzzles, Rubik's Cube pales in comparison with the latest creation of Rice University geoscientist Richard Gordon. Gordon and collaborators Chuck DeMets of the University of Wisconsin-Madison and Donald Argus of NASA's Jet Propulsion Laboratory in Pasadena, Calif., have just put the finishing touches on a 20-year labor of love, a precise description of the relative movements of the interlocking...

PASADENA, Calif. -- Humans have yet to see Earth's center, as did the characters in Jules Verne's science fiction classic, "Journey to the Center of the Earth." But a new NASA study proposes a novel technique to pinpoint more precisely the location of Earth's center of mass and how it moves through space. Knowing the location of the center of mass, determined using measurements from sites on Earth's surface, is important because it provides the reference frame through which scientists...

JPL -- New NASA research confirms that northern metropolitan Los Angeles is being squeezed at a rate of 5 millimeters (0.2 inches) a year, straining an area between two earthquake faults that serve as geologic bookends north and south of the affected region. The compression of the Los Angeles landscape is being monitored by a network of more than 250 precision global positioning system receivers known as the Southern California Integrated Global Positioning System Network, as well as by...
