Background
The Barrow magnetic observatory was established in 1949, with major upgrades in 1957 associated with the International Geophysical Year. The current physical plant was put into place in 1975. The observatory is of particular importance to the Geomagnetism Program because it is the most northerly of all the USGS observatories, being located well within the auroral oval. The observatory is operated with the cooperative assistance of the Climate Monitoring and Diagnostics Laboratory of NOAA.
