TEAMER: Passive Acoustic Measurements around ORPC Turbines in Millinocket, ME and Igiugig, AK
Drifting acoustic measurements obtained around ORPC turbines in Millinocket, ME (August 2023) and Igiugig, AK (June 2024). The data was collected to understand how much underwater noise ORPC river turbines produce and how that noise changes with turbine operation. Data was gathered by releasing small, floating sensor systems that moved with the river current. These measurements were made using the shallow version of the Drifting Acoustic Instrumentation SYstem (DAISY), which recorded underwater sound while drifting past the turbines. At the same time, turbine performance data, such as rotation speed and power output, were recorded and time-synchronized with the acoustic data. This approach researchers to compare turbine operating conditions directly with measured sound levels, helping them identify how and why turbine activity affects the surrounding underwater sound environment.
