Water Velocity and Turbulence Data from Sequim Bay, WA, collected between 2016 and 2025

In progress License

Collection of publishable datasets from bottom-lander deployments of acoustic Doppler instrumentation in Sequim Bay, WA measured between 2016 and 2025. These data primarily consist of water velocity measurements from ADCPs deployed by PNNL in both the inlet and the bay itself.

Raw data were processed either using custom MATLAB code or the DOLfYN submodule of the MHKiT Python package. ADCP velocity data are typically saved in the East-North-Up coordinate frame, while ADV velocity and turbulence data are saved in principal (streamwise-cross_stream-up) reference frame.

Data products are provided in a new tiers:
.ad2cp or .000: raw binary datafile from the instrument
.a1: processed and quality controlled data, stored in netCDF4 format
.b1: bin-averaged data, stored in netCDF4 format

Deployments are saved under the month and year that they began. Figures and technical reports, if available, are included with the datasets.
