Governing Council & Executive Committee

The Governing Council is the ruling body of the ISC. Representatives of the member institutions meet in alternate years, in conjunction with IUGG and IASPEI Assemblies. The Council elects a Chairperson and members of an Executive Committee from its ranks.

The Governing Council Chair makes urgent policy decisions between meetings of the full Council. The current Chair is Dr. John Adams of the Geological Survey of Canada.


The Executive Committee guides the ISC in implementation of policies defined by the full Governing Council. It consists of up to 6 voting members elected from the Governing Council, and ex officio members representing IASPEI and the ISC's host institution.
