Below is a list of investigations selected by NASA's Geodynamics Program for the "Dynamics of the Solid Earth" Investigators Working Group. This effort was led by Dr. Bruce Bills of NASA's Goddard Space Flight Center, and Dr. Paul Lundgren of NASA's Jet Propulsion Laboratory, who served 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 promised scientific and technological advances which furthered 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 improved 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.
