SCOR Secretariat

The SCOR Secretariat is responsible for the day-to-day administration of SCOR activities, taking its guidance from the General Meetings, Executive Committee Meetings, and communication with the Executive Committee and Nominated Members. This communication includes frequent contacts with national committees and chairs of SCOR subsidiary bodies and organizations. The Secretariat is also responsible for the administration of SCOR finances, organization of the meetings of SCOR and its subsidiary bodies, management of a program of travel grants, and preparation of SCOR publications. The small size of the SCOR Secretariat is possible because of the significant contributions to SCOR projects made by participants in SCOR working groups, research projects, and other activities.

The SCOR Secretariat is located at the

College of Earth, Ocean, and Environment
003 Robinson Hall
University of Delaware

At SCOR’s beginning, SCOR’s elected Secretary or President provided the necessary secretariat function. In 1972, a part-time Executive Secretary was appointed at the Royal Society (UK) to assist the elected Secretary. In 1985, as the scope and activities of SCOR had grown substantially, the Executive Secretary became a full-time employee; the title was changed to Executive Director in 1990. The Secretariat moved over the years from the Royal Society (UK) to Dalhousie University (Canada) in 1980, to Johns Hopkins University (USA) in 1992, and to the University of Delaware (USA) in 2007.
