Acoustic Modems Proven Once Again For Long-term Real-time Monitoring

In early 2004, LinkQuest Inc. supplied a set of UWM1000 modems to Sound Ocean Systems Inc. (SOSI), Seattle, Washington. SOSI has integrated the acoustic modems with an acoustic current profiler, SOSI's surface buoy and bottom platform for Bodega Marine Laboratory. This real-time current monitoring system was installed in Bodega Bay of Northern California, a particularly challenging environment for acoustic communication due to the disturbance caused by high winds on the northern coast of California. Recently, the system has surpassed one year of operation. Tens of megabytes of valuable current data have been collected without encountering a single problem.

At the meantime, the UWM2000 system installed by USGS for monitoring Lower Hudson river's discharge and sediment flux has entered its 4th year of continuous operation. Reliable communication has been achieved consistently in a challenging shallow-water horizontal environment. It is estimated that over 100 megabytes of data have been collected over this period.

Numerous other systems have also been in operation all over the world for long-term real-time underwater monitoring projects with a huge amount of accumulated data. The robustness, the high data rate and the power efficiency of the advanced Broadband Acoustic Spread Spectrum (BASS) technology used in LinkQuest's acoustic modems have made these deployments routine successes.
