U.S. Forum for the International Arctic Science Committee (IASC)

The U.S. delegation to IASC aims to increase two-way communication with the US Arctic research community through IARPC Collaborations.

Scope of activities

IASC is a nongovernmental scientific organization established to encourage and facilitate international consultation and cooperation in all aspects of arctic research, in all countries engaged in arctic research, and in all areas of the arctic region. The mission is to encourage, facilitate, and promote basic and applied interdisciplinary research in or concerned with the Arctic at a circumarctic or international level and to provide scientific advice on arctic issues. IASC is multidisciplinary, covering the full range of natural and social sciences. Working Groups, composed of representatives appointed by their countries to cover specific disciplinary issues, provide the main forums for developing IASC scientific programs and activities.
