DOSE Investigator Listing

Below is the list of investigations selected as NASA's Geodynamics Program's portion of the "Dynamics of the Solid Earth" Investigators Working Group. This effort is being led by Dr. Bruce Bills of the GSFC and Dr. Paul Lundgren of the Jet Propulsion Laboratory who will serve as the Center Scientists. The listed Investigations were selected from over 160 submissions and were selected on the basis of the scientific peer review and programmatic considerations. The final selections were difficult because of the large number of excellent proposals which were submitted. These investigations promise scientific and technological advances which will further our understanding of the global pattern of plate motions and the regional deformations which occur along the plate boundaries and the response of the Earth to loading and unloading phenomena. In addition, these investigations will improve the precision and accuracy of space geodetic techniques while working toward the establishment of the geodetic portion of the Fiducial Laboratories for a Natural Science Network (FLINN). We would like to thank all of those who have shown an interest in this program, especially those who offered their time and expertise to help complete the scientific review of the proposals.
