The NOAA National Ocean Service operates and maintains the Physical Oceanographic Real-Time System (PORTS®) in the Nation's major ports, harbors and bays. Environmental parameters, such as water levels, currents and a host of other hydrological and meteorological variables are monitored in real-time. Waves are also becoming increasingly important to the PORTS® users. Other users, such as those involved in marsh restoration projects, also require these data.

Improvements in the measurement methods and technology are continuously evolving in the PORT® program. This paper describes a partnership project for current and wave measurements in the Chesapeake Bay. The goals are two folds: 1) obtain current and wave data, and 2) test new measurement method and technologies. Instruments used include a Triaxys directional wave buoy, and 1200 and 600 KHz Acoustic Doppler Current Profilers (ADCPs) that measures both currents and waves. Both wave-measuring instruments have been validated through laboratory and field tests. Data are recorded internally and telemetered via underwater modems, line-of-sight radio and ARGOS. The hourly wave and 6-minute current data are to be used to validate wave and oil spill trajectory models and to support marsh restoration projects. This paper includes instrumentation, measurement design, sensor validations, and experience in field deployments.
