Velocity and Turbulence Measurements at Three Locations in the Salish Sea, WA, 2017

Published by Pacific Northwest National Laboratory | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-11-11T04:00:56Z
This submission contains raw and processed datasets of water velocity and turbulence measurements from 3-day deployments of Deepwater Buoyancy StableMoor buoys carrying acoustic Doppler instrumentation at locations in Rosario Strait, Bellingham Channel, and Tacoma Narrows, WA in 2017. Two StableMoor buoy configurations were used at these sites. The StableMoor500 carried a nose-mounted acoustic doppler velocimeter (ADV) and a down-looking acoustic doppler current profiler (ADCP), and the StableMoor400 carried dual wing-mounted ADVs located on either side of the nose and a down-looking ADCP. Each StableMoor was designed to fly at an altitude of 10 m above the seafloor. The StableMoor500 was deployed in Bellingham Channel at 48.5601 N, 122.7501 W in 86 m of water from July 24, 2017 - July 27, 2017. The down-looking ADCP malfunctioned, and therefore there is no ADCP data at this site. The StableMoor400 was deployed in Rosario Strait mooring at 48.5800 N, 122.6597 W in 52 m of water from July 24, 2017 - July 27, 2017. Both buoys were deployed in Tacoma Narrows at 47.2766 N, 122.5466 W and 47.2769 N, 122.5471 W in 36 m of water from Nov 14, 2017 - Nov 17, 2017. Nortek Vector ADV measurements were recorded continuously at 16 Hz. Data was motion-corrected using the internal measurement unit (IMU) and external ADCP bottom-track data, bin-averaged into 10 minute bins, and then converted to the Principal (streamwise, cross-stream, vertical) coordinate system. Parameters include water velocity, turbulence intensity, turbulent kinetic energy (TKE) components, Reynolds shear stress components, TKE dissipation and production. Teledyne RDI Workhorse 1200 kHz ADCP measurements were recorded continuously at 2 Hz with bottom-track enabled. Water velocity was averaged into 10 minute bins and converted into the Principal coordinate system. One ADV with the highest quality motion-corrected was fully processed from each deployment site: the nose-mounted ADV at Bellingham Channel, the starboard-wing mounted ADV at Rosario Strait, and the port-wing mounted ADV at Tacoma Narrows. Raw data stored in this submission can be read using DOLfYN v1.3.1, available through the MHKiT python package, and was processed using Tsdat v0.7.5. Processed data are stored in netCDF4 format and can be easily viewed using the Linux "ncdump" command or read through the Xarray python package.
