Post-hurricane marsh restoration efforts have included sediment deposition, planting of vegetation, and restoring tidal hydrology. The work presented here is part of a larger project funded by the National Fish and Wildlife Foundation (NFWF) to monitor the post-restoration ecological resilience of coastal ecosystems in the wake of Hurricane Sandy. The U.S. Geological Survey Woods Hole Coastal and Marine Science Center made in-situ observations during 2018-2019 and 2022-2023 at two sites: Thompsons Beach, NJ and Stone Harbor, NJ. Marsh creek hydrodynamics and water quality including currents, waves, water levels, water temperature, salinity, pH, dissolved oxygen, turbidity, organic matter, chlorophyll-a, and suspended-sediment concentration and organic content were measured at both sites. Additionally, marsh accretion and erosion were evaluated and used to interpret sediment budgets. These ecological data will be coupled with topographic lidar and imagery to explain the processes responsible for coastline evolution, and to evaluate restoration techniques and assess whether storm vulnerability has decreased relative to unaltered environments. Purpose: Discharge was measured over 7 hours of a semidiurnal tidal cycle at Thompsons Beach, NJ in 2018 and 2022 with a Teledyne RDI Rio Grande 1200-kilohertz acoustic Doppler current profiler (ADCP). Measurements were made during maximum flood and ebb tidal currents, which occur on either side of high tide, to capture maximum positive and negative discharge. Downward-looking ADCP transect data will be used to create an index-velocity model between flow velocity at a single location in the channel and the average channel velocity. The model will be used to estimate a time series of total channel discharge from long-term deployments of velocity sensors.

Other_Citation_Details: P/N 957-6231-00 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The Teledyne RDI Workhorse Rio Grande 1200 kHz ADCP has a temperature range of -5 to 45 degrees Celsius with accuracy +/- 0.4 degrees Celsius, a tilt range of +/-5 degrees with accuracy of +/-0.5 degrees, a compass with accuracy of +/-2 degrees, velocity range of +/-5 m/s with an accuracy of +/-0.25% of the velocity, and 4 beams with ping rate of 2 Hz. The QRev software calculates discharge from depth, boat velocity, and water velocity. The ADCP cannot measure near the water's surface due to the immersion of the ADCP in the water. The ADCP also cannot measure all the way to the streambed because of sidelobe interference. The discharge in the missing data regions at the top and bottom of the water column and the edges of the channel must be estimated. The discharge estimates for these unmeasured portions are based on extrapolation methods. The QRev software automatically selects the best extrapolation method. The computed discharge is a summation of the measured portion of the transect, and the extrapolated estimates for the top, bottom, and edges. While a generally accepted method for estimating discharge uncertainty does not exist, the QRev software provides some simple estimates of the likely error sources. Logical_Consistency_Report: Data were processed with QRev 4.34, which uses a color-coded error message scheme in its graphical user interface to indicate potential areas of concern. Error messages such as temperature range greater than 2 degrees, excessive boat movement at edges, zero edge discharge, and sign of total discharge not consistent are to be expected since measurements were made in a tidal channel over 7 hours of a semidiurnal tidal cycle. QRev flagged some higher than normal invalid ensembles and bottom track (BT) error velocities, but total discharge values are deemed valid. Completeness_Report: The dataset is considered complete for the information presented. Each good transect is designated in QRev with a checkmark. Bad transects can be unchecked to remove them from display in QRev. Eight transects were removed (unchecked) during processing because they contained data for more than a full transect or had other operational errors. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Explicit latitude and longitude values are not provided in the transect dataset. Horizontal position is determined via bottom track velocity using at least three beams to compute u, v, and w velocities in orthogonal coordinates (x, y, and z). The data are corrected for pitch and roll, and rotated according to the magnetic compass resulting in Earth coordinates (east, north, up). An error velocity is calculated from the fourth beam as the difference in vertical velocity and is used to screen for invalid data. Sources of error include sudden acceleration/deceleration or turns of the moving boat. A compass calibration, water temperature validation, and stationary moving bed test were performed to minimize error. Additionally, salinity was entered to more accurately estimate the speed of sound in water. Bottom tracking has a typical single-ping accuracy of a few mm/s. In 2018, the latitude and longitude of the transect edges were measured with an SP80 RTK system with a theoretical horizontal accuracy of 2 cm on any single point. However, repeat occupations of the same spot suggest slightly higher uncertainties up to 5-10 cm including user error. In 2022, the latitude and longitude of the transect edges were measured with a Garmin GPSMAP 78sc handheld GPS. The expected absolute, horizontal accuracy is stated to be 3 to 5 m at the 95% confidence level using the WAAS setting. The Garmin GPS collects data in the WGS84 datum; however, it is reported in the NAD83 datum as the difference in the values of the latitude and longitude is within the error of the sensor. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The Teledyne RDI Workhorse Rio Grande 1200 kHz ADCP was set to Water Mode 11 and Bottom Mode 5. Depth was computed from the transducer depth as a 4-beam average using the inverse depth-weighted method. The transducer distance to surface was entered in the software. Spikes in the data were filtered out using a robust LOESS smooth filter. Depth calculations were not corrected for pitch and roll. A preliminary assessment by Teledyne indicated an approximately 0.4% change in average depth for a mean pitch and roll of 5 degrees. Explicit depth values are not provided in the dataset, but depths are viewable in the transect figures displayed in QRev. Lineage: Process_Step: Process_Description: Discharge data were collected using a Teledyne RDI Workhorse Rio Grande 1200 kHz acoustic Doppler current profiler (ADCP) in a tidal channel at Thompsons Beach, NJ. Data were collected on October 9 and 10, 2018 and September 27, 2022. Stakes were driven into the East and West banks of the channel to mark the transect edges. In 2018, the ADCP was mounted in a trimaran boat that was pulled across the creek by hand using a line that was strung across the creek. In 2022, the ADCP was mounted on a remote-controlled boat and the boat was driven repeatedly across the channel between the stakes, collecting data during each transect crossing over 7 hours of a semidiurnal tidal cycle. In 2018, the stakes were located at 39.19564 N, 74.98369 W on the East bank, and 39.19538 N, 74.98442 W on the West bank. In 2022, the stakes were located at 39.19549 N, 74.98366 W on the East bank, and 39.19536 N, 74.98434 W on the West bank. The coordinates are in the North American Datum of 1983 (National Spatial Reference System 2011). Measurements were made during maximum flood and ebb tidal currents, which occur on either side of high tide, to capture maximum positive and negative discharge. ADCP data were recorded and initially reviewed using WinRiver II version 2.18. WinRiver II is available at https://hydroacoustics.usgs.gov/movingboat/WinRiverII.shtml. The raw data were recorded in .mmt and .pd0 files, which are the native file formats of WinRiver II.

QRev automates data-quality checks, data filtering, extrapolation methods, and invalid-data-handling steps, and provides estimates of uncertainty to help guide the user. QRev is available at https://hydroacoustics.usgs.gov/movingboat/QRev.shtml. Processing in QRev adhered to the defaults with additional steps as outlined below. An independent temperature reading collected with a YSI EXO2 multiparameter sonde was entered to provide a check for the ADCP measured temperature in accordance with USGS policies. Salinity was applied based on field measurements of water-column salinity using a YSI EXO2 multiparameter sonde. Using a field-measured salinity improves the estimate of speed of sound in water, which is used in computing discharge. The magnetic variation was calculated using NOAA's Magnetic Field Calculator (https://www.ngdc.noaa.gov/geomag/calculators/magcalc.shtml) and entered for each file. For data collected October 9, 2018, a bad transect (#000), which included data from two channel crossings, was removed (unchecked) from the final dataset. For data collected October 10, 2018, bad transects (#014, #021, #023, #036) were removed (unchecked) from the final dataset. These were removed because they contained data either for more than a full transect or had other operational errors. For Transects #015-035, the left and right banks were entered incorrectly in the field, so the left and right banks were switched during data processing. For data collected September 27, 2022, bad transects (#002, #010, #048) were removed (unchecked) from the final dataset because they contained data for more than a full transect or had other operational errors. The starting edge distance was changed to 0.0 for transect #017 as it was entered incorrectly in the field. Additionally, the left bank was changed to the right bank and the right bank was switched to the left bank in order to match the designated left and right banks in 2018 so the direction of the discharge would be the same in 2018 and 2022 (ebb-positive convention). The data were exported from QRev as a .mat file using bottom-track (BT) navigation reference.
