The Geomagnetic Program, then part of the US Coast and Geodetic Survey, began work in Fairbanks during the Second International Polar Year, 1932-1934, as part of an effort with the Department of Terrestrial Magnetism of the Carnegie Institution. Collaborative work with the University of Alaska began in the 1940's, with the full-fledged College observatory commencing operation in 1948. Today, the College observatory is located on the College International Geophysical Observaotyr (CIGO), a facility established in 1996 through a collaborative effort between the USGS Geomagnetism Program and the University of Alaska. The CIGO is managed by the University's Geophysical Institute. In 2009, the 46-acre site was renamed to the Jack Townshend CIGO, in honor of longtime USGS employee Jack Townshend, the visionary and developer of the site.
