NOAA Returns to Yellowstone National Park for Collaborative International Project (NGS)
The National Geodetic Survey (NGS) will return to Yellowstone National Park for the fourth consecutive year to perform GPS and absolute gravity measurements in support of a research study conducted in collaboration with the University of Colorado, Boulder, and the University of Luxembourg. The study seeks to use gravity change and GPS uplift rates to help resolve which of several mechanisms is responsible for uplift and inflation of the volcano. Mechanisms under consideration for the ongoing uplift are the intrusion of magma into the underlying crust, or by the release of trapped pressurized water and gas (i.e., to volumetric expansion), or by other mechanisms not yet considered. For more information, contact Tim Wilkins.
