Oceanography & Measurement Systems: Representative Projects

Woods Hole Group provided a (Physical Oceanography Real-Time System) PORTS system for monitoring currents in the approaches to the main shipping channel at Long Beach Harbor, CA. An Acoustic Doppler Current Profiler (ADCP) is installed on a Xenon Corporation conical fiberglass bottom platform located 1km west of the entrance to the harbor breakwater. The ADCP sends data by armored cable to a Woods Hole Group Remote System Manager (RSM) located on a breakwater. The data are forwarded from there to a Base Station display PC in the Pilots Office on shore by spread-spectrum radio telemetry. The display PC contains a software package that manages reception of data from the RSM, and from local wind sensors, and displays and stores the data. A typical data display shows the most recent current vectors at several depths and a current profile, as well as a recent time history. This system was installed in summer 1999. Woods Hole Group performed the installation and has also provided services (includes software upgrades.)
