Data were collected in Lindsey Slough in April 2017, and Middle River and the Mokelumne River in March 2018. Data files are grouped by location. At each of the three sites, data were collected at stations outside and within patches of vegetation, to determine how submerged invasive vegetation influences tidal currents and suspended-sediment concentration. The Table below shows the data types collected at each station, and classifies stations as Vegetated (V) or Unvegetated (U). These data were collected as part of a study of the effects of invasive aquatic vegetation on sediment transport in the Sacramento-San Joaquin Delta. At times, vegetation caught on instrument frames (both within and outside patches) compromised data quality. Users are advised to check data quality carefully, and to check metadata and instrument information, as individual instrument deployment times vary. Purpose: The data were collected to determine how submerged invasive vegetation influences tidal currents, suspended-sediment concentration, and sediment flux. The survey was conducted as part of a cooperative project, with the USGS California Water Science Center and the California Department of Fish and Wildlife, to provide critical data about the impact of Invasive Aquatic Vegetation (IAV) on fish habitat and the health of marshes to agencies that manage and control IAV in the Delta. These data are intended for science researchers, students, policy makers, and the general public.

Logical_Consistency_Report: No formal logical accuracy tests were conducted. Data fall within expected ranges. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal accuracy derived from GPS instrumentation is less than 1 m. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: There are two sources of uncertainty associated with vertical positioning of the instruments: 1) the measuring tools used during instrument mounting, 2) the amount of settling that occurs during deployment. There was no evidence that the platforms settled to a large degree. Combined sources result in an uncertainty of 5 cm. Lineage: Process_Step: Process_Description: Instruments deployed in Lindsey Slough. Instruments included in deployment are: RBR solo DWave and TWR-2050 bursting pressure sensors, RBR CTD, Seapoint turbidity meter, Nortek single point acoustic doppler velocimeter, Nortek acoustic doppler profiler, RDInstruments acoustic doppler current profiler. Process_Date: 20170403 Process_Step: Process_Description: Instruments were retrieved and the data from the retrieved instruments were post-processed using manufacturers software packages and USGS matlab codes. Process_Date: 20170417 Process_Step: Process_Description: Instruments deployed in Middle River and Mokelumne River sites. Instruments included in deployment are: RBR TWR-2050 and Duo bursting pressure sensors, RBR CTD, Seapoint turbidity meter, Nortek single point acoustic doppler velocimeter, Nortek acoustic doppler profiler, RDInstruments acoustic doppler current profiler. Process_Date: 20180312 Process_Step: Process_Description: Instruments were retrieved and the data from the retrieved instruments were post-processed using manufacturers software packages and USGS matlab codes. Process_Date: 20180327 Process_Step: Process_Description: Data were accumulated into NetCDF files. During post-processing, data collected when instruments were out of the water were removed from the time series. Bad data points identified by 1) the deployment and recovery times, 2) data flagged as erroneous by the manufacturer, 3) amplitude or correlation values outside of predetermined quality thresholds for the velocimeter, were removed. The files include data of intermittent poor quality due to interference by vegetation caught on frames. In a few datasets with persistent vegetative interference the compromised data were removed, as noted in the associated metadata. Turbidity data are raw unless otherwise noted, and include high values that may be attributable to vegetation. Use of these data requires careful assessment of data quality. Process_Date: 20200218 Process_Step: Process_Description: Files were named with a convention that uses a 12- to 15-digit alpha-numeric code. The first three characters for this dataset are all 'IAV' for the experiment name; the fourth and fifth positions represent the calendar year in which the first data point in the file was taken (18, 2018); the sixth, seventh and eighth characters are an alphanumeric code for the site name (DNA, DNB etc.); the ninth and tenth characters represent the instrument position on the platform, where 01 is the top-most. Next is a two- or three-character code for the instrument type (vec, Norteks Acoustic Doppler Velocimeter; aqd, Norteks Acoustic Doppler Profiler; pt, RBRs bursting pressure sensor with temperature; ctd, RBRs CTD; tu, RBRs Virtuoso turbidity sensor; ls, Sequoia Scientifics LISST). There are an additional 2 characters for instruments that collect in a bursting pattern to indicate whether the file includes the burst data (-b) or the statistics and/or singular observations of the burst (-s). This indicator is omitted if there is no bursting pattern.
