Canadian Geophysical Union

The Canadian Geophysical Union (French: Union géophysique canadienne) (CGU) is a society dedicated to the study of Earth and its space environment, including the Sun and solar system.

The organization began in 1945 as an Associate Committee of the National Research Council Canada.

It amalgamated with the Canadian committee for the International Union of Geodesy and Geophysics in 1946 and was renamed as the Associate Committee of Geodesy and Geophysics of the NRC.

The organization was replaced in 1974 by the Canadian Geophysical Union with John Tuzo Wilson as its first president.
