Elizabeth A. Nystrom 20250416 tabular digital data https://doi.org/10.5066/P1ZNV7WP This child item data set contains acoustic Doppler current profiler (ADCP) data collected during 2023 from an uplooking tripod in Sodus Bay (USGS station number 431533076582101). This data set includes the raw binary data files from the ADCPs as well as tabulated text files of echo intensity, backscatter, velocity, and ancillary data. Tables were created by processing raw data files in R-language oceanographic package OCE (Kelley and others, 2022) and TRDI WinRiver II (Teledyne RD Instruments, 2007). All aggregation, manual magnetic variation calculations, and post-processing were completed using Python libraries pandas (McKinney, 2010) and NumPy (Harris and others, 2020). These data were collected in cooperation with New York Sea Grant, the Cooperative Science and Monitoring Initiative, and the U.S. Environmental Protection Agency as part of a larger study of primary production in the Bays of Lake Ontario. 20230623 20231108 ground condition Complete None planned USGS Station ID 431533076582101 -76.9724806 -76.9724806 43.2593 43.2593 ISO 19115 Topic Category environment biota inlandWaters None ADCP Acoustic Doppler current profiler Water velocity Echo intensity Backscatter Internal seiche Water column USGS Thesaurus acoustic doppler current profiling water temperature water column reflectivity limnology algal blooms USGS Metadata Identifier USGS:6602ffaed34e64ff1548e475 None New York Lake Ontario Sodus Bay USGS Station ID 431533076582101 None.

All collected data were broadly checked for accuracy in accordance with USGS protocols and guidance. Erroneous data were removed from the data set. Data were checked for numerical errors and consistency, but no formal logical accuracy tests were conducted. The dataset is considered complete for the information presented as described in the abstract. It is advisable to carefully read the metadata for additional details. A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. A formal accuracy assessment of the vertical positional information in the data set has not been conducted. Data were collected using ADCPs mounted to fixed fiberglass tripods. Before deployment, the ADCP compass was calibrated, the clock synced, built-in predployment tests were run, and deployment commands were sent to the instrument. Data were recorded on internal memory cards. 48 volt DC power was supplied to the ADCP from internal battery packs. 2023 Raw ADCP data files in *r.000 format were read into the R-language oceanographic coding package OCE and subset into three main categories before exporting as standard *.csv tables. Echo intensity was subset by beams 1-4 and the average of the four beams was included as a fifth table. Velocity tables were then subset in component form as North, East, Vertical, and Error Velocity. A time-series table was also created to include one-dimensional parameters: roll, pitch, heading, transmit current, transmit voltage, ambient temperature, and attitude temperature. 20240105 Raw ADCP data files in *r.000 format were loaded in to TRDI software WinRiver II for the export of measured backscatter tables. These tables were subset by beams 1-4, and a fifth table of the average of the four beams was included. 20230913 Subsets exported from raw data files through OCE and WinRiver II were aggregated over their respective time series into fifteen complete tables using pandas data frame tools in Python. 20240105 Corrections for magnetic variation were made to the raw data by the instrument during data collection by use of the EB command. Magnetic variation was calculated for the location of deployment. 20230913 Data in bins 14 to 20 near the water surface (depths of 1 meter or less) were removed from the tabular data to account for side-lobe interference. 20230913 SDS23000r.000 Raw binary ADCP data file.
