Global
Geodynamics Project (GGP)
This is a major
international project, which involves measuring and analyzing
temporal changes in the the Earth's gravity field over a 6-year period (July1,
1997 - June 30, 2003). Many details for the goals, the stations and activities
of the project are described on the GGP Webpage http://www.eas.slu.edu/GGP/ggphome.html
An introduction to the project can be found in the following:
