Advancing Environmental Monitoring through Integrated Instrumentation

Abstract

Environmental monitoring of marine energy converters must satisfy three directives: 1) not bias marine animal behavior, 2) not miss rare events, and 3) not accrue unmanageable volumes of data. These cannot be simultaneously satisfied by any single sensor, which motivates the development of integrated instrumentation solutions. The Adaptable Monitoring Package (AMP) combines the capabilities of an acoustic camera, multibeam sonar, optical cameras, hydrophones, and an acoustic Doppler current profiler. Real-time target detection and tracking was implemented using the acoustic camera and multibeam sonar, and was used to trigger data acquisition when a target was present. This scheme produced a 73% true positive rate and a 99% true negative rate. A 43% duty cycle would be required to detect 50% of the targets acquired using triggered acquisition, which would yield 1.7 TB of low-value data per day.
