Demand for real-time directional wave data has recently surged. However, does the technology exist that will allow the user to place an instrument where he wishes and still be able to telemeter the data to shore? Coastal industrial operations, resource management requirements and integrated ocean observation systems have been growing rapidly in importance and number over the past two decades. A key reason for the success of these programs is the ability to provide real-time ocean data products. Directional wave data are among the most important products for safe personnel and vessel operations, and are easy for the public to use, appreciate and advocate. In an effort to provide similarly accurate wave measurements as surface wave buoys, Nortek has developed the AWAC (Acoustic Wave And Current) sensor, which remains safely on the ocean bottom, away from the dangers of ships, storms and vandalism. The AWAC is a combination acoustic Doppler current profiler and directional wave gauge. This article describes the innovative AWAC measurement methodology, wave processing algorithms, data products and real-time telemetry solutions.
