The National Ocean Service (NOS) is an office within the U.S. Department of Commerce National Oceanic and Atmospheric Administration (NOAA). It is responsible for preserving and enhancing the nation's coastal resources and ecosystems along the of shoreline bordering of coastal, Great Lakes, and ocean waters. Its mission is to "provide science-based solutions through collaborative partnerships to address evolving economic, environmental, and social pressures on our oceans and coasts." The office works with partnered agencies to ensure that ocean and coastal areas are safe, healthy, and productive. Its projects focus on working to ensure safe and efficient marine transportation, promoting the protection of coastal communities, and conserving marine and coastal places. It employs 1,700 scientists, natural resource managers, and specialists in many different fields. The National Ocean Service was previously known as the National Ocean Survey until it was renamed in 1983. Organization As one of six NOAA Line Offices, NOAA's National Ocean Service (NOS) observes, studies, and manages the nation's coastal and marine resources. NOS measures and predicts coastal and ocean phenomena, protects large areas of the oceans, works to ensure safe navigation, and provides tools and information to protect and restore coastal and marine resources. NOAA's National Ocean Service is composed of seven programs and two staff offices. Program offices Center for Operational Oceanographic Products and Services (CO-OPS) National Centers for Coastal Ocean Science (NCCOS) Office of Coast Survey (OCS) Office for Coastal Management (OCM) National Geodetic Survey (NGS) Office of National Marine Sanctuaries (ONMS) Office of Response and Restoration (OR&R) Staff offices Integrated Ocean Observing System Program (IOOS) Management and Budget Office (MBO) Center for Operational Oceanographic Products and Services The Center for Operational Oceanographic Products and Services (CO-OPS) is a source for water-level and current measurements that support safe and efficient maritime commerce, sound coastal management, and recreation. CO-OPS is composed of four divisions: Field Operations Division The Field Operations Division (FOD) operates and maintains all oceanographic and Great Lakes observing systems required to meet CO-OPS' mission objectives. The Division monitors the continuous operations of navigation and other real-time observing systems to support the protection of life and property. FOD also operates the Ocean Systems Test and Evaluation Facility (OSTEF) to support Requirements and Development Division (RDD), and Information Systems Division (ISD) development efforts. FOD operates equipment to evaluate new observing systems and software modules developed to support NOS mission objectives. The Division installs, documents, operates and
