The lander was deployed at 60.7207031 N, 151.4294998 W in ~50 m of water.\n\nThe dataset contains raw and processed data from the following two instruments:\n\n1. A Nortek Signature 500 kHz acoustic Doppler current profiler (ADCP). Data were recorded in 4 Hz in the beam coordinate system from all 5 beams. Processed data has been averaged into 5 minutes bins and converted to the East-North-Up (ENU) coordinate system.\n\n2. A Nortek Vector acoustic Doppler velocimeter (ADV). Data were recorded at 8 Hz in the beam coordinate system. Processed data has been averaged into 5 minutes bins and converted to the Streamwise - Cross-stream - Vertical (Principal) coordinate system. Turbulence statistics were calculated from 5-minute bins, with an FFT length equal to the bin length, and saved in the processed dataset.\n\nData was read and analyzed using the DOLfYN (version 1.0.2) python package and saved in MATLAB (.mat) and netCDF (.nc) file formats. Files containing analyzed data (\".b1\") were standardized using the TSDAT (version 0.4.2) python package. \nNetCDF files can be opened using DOLfYN (e.g., `dat = dolfyn.load(''*.nc\")`) or the xarray python package (e.g. `dat = xarray.open_dataset(\"*.nc\"). \n\nAll distances are in meters (e.g., depth, range, etc), and all velocities in m/s.
