These data primarily consist of water velocity measurements from ADCPs deployed by PNNL in both the inlet and the bay itself. \n\nRaw 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.\n\nData products are provided in a few tiers:\n   .ad2cp or .000: raw binary datafile from the instrument\n   .a1: processed and quality controlled data, stored in netCDF4 format\n   .b1: bin-averaged data, stored in netCDF4 format\n\nDeployments are saved under the month and year that they began. Figures and technical reports, if available, are included with the datasets. For more information on the deployments and data structure please see the \"README.txt\" resource below.
