The success of AGU is due in large part to a dedicated volunteer leadership that reflects the diverse interests of the international geophysics community. All aspects of the Union's programs rely on the volunteer efforts of members who respond to AGU's motto, “unselfish cooperation in research.”
Ten scientific disciplines are represented in the Union's governing body, the AGU Council, which is the central authority for all Union affairs. The various programs of AGU are initiated and reviewed by a comprehensive group of committees appointed by the President of the Union. These activities range from recognizing the achievements of colleagues and setting the program for AGU's annual meetings to drafting Union position statements and investigating advances in information technology.
