Seminar in Geophysics: Thermal and Chemical Evolution of the Earth
An international electronic forum for the free exchange of knowledge, programs and data between scientists engaged in the study of the Earth using electromagnetic methods, principally magnetotellurics.
A detailed article explaining the practical application of magnetotellurics. Includes case studies to present processing and interpretation techniques.
Contains resources of the Geological Survey of Canada on the ever-changing magnetic field. Includes a magnetic declination calculator and compass tutorial, and a database from Canadian magnetic observatories.
Historical review of geomagnetism, from the discovery of the compass to plate tectonics and space observations. Also has instructions for teachers, glossary, and FAQ.
Technical support, guidance, and applied research that fosters the appropriate use of surface and borehole geophysical methods for USGS interdisciplinary earth science investigations and the development of geophysical characterization and monitoring methods.
