At a 1989 meeting in Coolfont, West Virginia, more than 135 scientists from 14 countries recommended a program for NASA Solid Earth Science for the next decade. The proposal included five new emphases: a global fiducial and strain network using geodetic techniques to measure lithospheric motion and deformation; high-resolution digital topographic data; land surface studies as records of climate change, tectonic events, and global soil cycles and degradation; studying volcanic processes, with emphasis on their interaction with climate; and using geopotential fields from space to improve understanding of lithospheric structure and core-mantle dynamics.
