    • TEAMER: Acoustics UW Tidal Turbine

    Metadata Updated: February 17, 2026

    This dataset contains underwater acoustic measurements collected around the University of Washington's pilot-scale cross-flow tidal turbine deployed at the entrance to Sequim Bay, WA through November, 2023 and February, 2024. Measurements are a combination of stationary observations at a distance of 100 m from the turbine and drifting observations that pass directly over the operating turbine. The study aimed to characterize turbine-generated sound and evaluate directional acoustic monitoring using vector sensors in a high-flow tidal environment. Measurements include calibrated acoustic pressure and three-dimensional particle velocity, supporting spectral, time-frequency, and bearing-resolved analyses of turbine sound relative to ambient and anthropogenic noise.

    Data in the data lake are organized into folders by contributor. UW contains drifting hydrophone (DAISY) pressure measurements and associated positional and environmental data. PNNL provides stationary vector sensor measurements (pressure + 3D particle velocity) from the November 2023 deployment. Integral includes NoiseSpotter vector sensor array measurements from November 2023 and February 2024. The report data within the Integral folder contains intermediate datasets used in the associated project report. Together, these data support studies of marine energy noise, particle motion exposure, and comparison of vector and pressure-only acoustic measurement methods.
