Working Groups

A Working Group is a group of experts that is established with specific terms of reference, by Council, based on the recommendation of Science Board. Most Working Groups report to parent Scientific Committees, others directly to Science Board. Most Working Groups meet annually to undertake specific tasks within their terms of reference. Science Board suggests the members of Working Groups in consultation with the PICES Chairman, and seeks Contracting Parties’ approval and support.

Currently PICES has the following Working Groups:
