The Office of Search and Rescue's Coordination Division (CG-SAR-2) is responsible for the coordination of Coast Guard, national and international related SAR related matters. The Coordination Division works with many different international, national, State, Tribal, Territorial/Insular Area, and local SAR authorities, as well as volunteer organizations and nongovernmental organizations in managing both the U.S. and global SAR system. Internationally, the Coordination Division provides U.S. SAR support and subject matter expertise in SAR matters discussed at the International Maritime Organization (IMO), International Civil Aviation Organization (ICAO), International Telecommunications Union (ITU), Radio Technical Commission Maritime (RTCA), and supports other regional SAR initiatives worldwide. Since 1974, the Coordination Division has served as the National SAR Committee (NSARC) Secretariat, supporting the NSARC Chair and eight member agencies by coordinating national level SAR matters and issues. In addition, the Coordination Division provides program management and oversight of the Automated Mutual Assistance Vessel Rescue (AMVER) System, a computer-based voluntary global ship reporting system used worldwide by SAR authorities to arrange for assistance to persons in distress at sea, serves as the Coast Guard representative and participates in the management and operation of the U.S. Search and Rescue Satellite Aided Tracking (SARSAT) Program, and manages the Coast Guard mass rescue response preparedness program.
