National Geomagnetism Program
The U.S. National Geomagnetism Program is a program directed by the USGS that monitors the Earth's magnetic field.[1]
History
[edit]- 1840–1845 Magnetic observatories at Harvard and Girard College
- 1860 Coast Survey begins regular magnetic observations at Maine's Fort Sullivan, Tift's Observatory in Florida and others
- 1882–1883 First International Polar Year
- 1901–1956 United States Coast and Geodetic Survey operates Cheltenham Magnetic Observatory in Maryland
- 1905–1918 USC&GS Explorer performs magnetic surveys
- 1909 Carnegie wooden survey ship built for Carnegie Institution for Science begins seven cruises to measure the Earth's magnetic field
- 1932–1933 Second International Polar Year
- 1956 Fredericksburg Magnetic Observatory in Virginia replaces Cheltenham[2]
