The Field Operations Division (FOD) operates and maintains all oceanographic and Great Lakes observing systems required to meet CO-OPS' mission objectives. The Division ensures the continuous operations of navigation and other real-time observing systems needed to support the protection of life and property. FOD also operates the Ocean Systems Test and Evaluation Facility (OSTEF) in order to support Requirements and Development Division (RDD), and Information Systems Division (ISD) development efforts. FOD operates equipment to test and evaluate new observing systems and software modules developed to support NOS mission objectives. The Division: installs, documents, operates and maintains CO-OPS measurement systems (e.g., NWLON, PORTS); conducts field reconnaissance and geodetic operations to include the establishment, leveling, documentation, and inspection of NOS benchmarks; and provides training in the installation, operation and maintenance of CO-OPS observing equipment.
