Line. Naval Oceanographers The Naval Oceanography community collects, analyzes, and then distributes data about the ocean and the atmosphere to Navy forces operating globally. Naval oceanographers are first on the scene - either literally in survey ships, or figuratively through computer prediction programs - in any military operation. There are approximately 430 Oceanography officers. They assist the war fighter in taking tactical advantage of the environment. They support the operational fleet from a variety of platforms. This can range from local area weather forecasting in support of aircraft carrier operations to optimizing the use of a sonar system in accordance with prevailing underwater sound conditions. Information Professionals The Information Professional Community is responsible for offensive and defensive Navy information operations to support requirements of theatre and operational commanders and national policy makers. They provide expertise in information, command and control, and space systems through the planning, acquisition, operation, maintenance, and security of systems that support Navy operational and business processes. Presently, there are billets for 535 officers. Human Resources The Human Resources community plans, programs, and executes life-cycle management of the navy's most important resource – its people. The primary focus will be on the human resources system: the combined elements of manpower, personnel, training, and recruiting. There are billets for 570 officers in this community, under the direction of the Chief of Naval Personnel. See also List of Naval Officer Designators References +
