Description:
Abstract:
Whales Tail Marsh, a restored salt pond in South San Francisco Bay, California, is experiencing rapid shoreline erosion. Determining whether the eroded sediment is exported to the ocean or imported via tidal channels and deposited on the marsh platform is critical to understanding the long-term response of the marsh to wave attack and sea-level rise. Quantifying water-column sediment flux helps to characterize the role of tidal channels in this process, and water discharge is a key component of sediment flux. To that end, discharge was measured repeatedly over diurnal tidal cycles in the tidal channels of the Whales Tail Marsh, within Eden Landing Ecological Refuge, California in the summer of 2021 and during king tides in the winter of 2021-2022. These transect data were collected by using a downward-looking Teledyne RDI RiverPro 1200-kilohertz acoustic doppler current profiler (ADCP) from a moving boat.
Purpose:
The discharge measurements were used as part of a process to create an index-velocity relationship (Ruhl and Simpson, 2005) between flow velocity measured at a single location within the channel and the channel-average velocity. This relationship enables the computation of a time-series of total channel discharge from long-term deployments of oceanographic instrumentation measuring at a single location within the channel. They were collected as part of a study to quantify sediment fluxes and changes in marsh morphology at Whales Tail Marsh in southern San Francisco Bay. These data are intended for researchers, students, policy makers, and the general public.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
No formal attribute accuracy tests were conducted. The Teledyne RDI Workhorse RiverPro 1200 kHz ADCP has a temperature range of -5 to 45 degrees Celsius with accuracy +/- 0.5 degrees Celsius, a tilt range of +/-90 degrees with accuracy of +/-0.3 degrees, a compass with accuracy of +/-1 degrees, velocity range of +/-5 m/s with an accuracy of +/-0.25 percent of the velocity +/- 2mm/s, and 4 beams with ping rate of 1-2 Hz. Data were processed using QRev. QRev uses a color-coded scheme in its graphical user interface to indicate potential areas of concern (e.g., percent change in discharge magnitude between consecutive transects). Because these measurements were made in tidal systems with highly variable bathymetry, these changes are expected and many of the yellow- and red-colored regions in QRev are to be expected. ADCP data were collected in 0.06 m depth bins. Variation in tidal elevation resulted in changes in the width of the measurable tidal channel. During the highest tides, the marsh was fully inundated and there was no defined edge to the channel. For this reason, all data has been retained and must be handled with care.
Logical_Consistency_Report:
Data were processed using QRev version 4.37 and reviewed by staff experienced in ADCP discharge measurements. All data were collected using the same instrument, computer, and moving-boat platform. QRev software 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 other error messages are to be expected since measurements were made in a tidal channel throughout the tidal cycle. Measurements at slack water included changes of flow direction from one edge to another.
Completeness_Report:
Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the metadata for each part of this data release carefully for additional details.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
GPS locations were collected using a Hemisphere A631 GNSS Smart Antenna. The GPS antenna was located directly above the ADCP during data collection. Based on manufacturer specifications, the locations are assumed to be accurate within 2 m Circular Error Probable (CEP).
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report: No formal assessment of vertical accuracy was performed.

Process_Description:
Discharge data were collected using a boat-mounted Teledyne RDI RiverPro 1200 kHz acoustic Doppler current profiler (ADCP), in one tidal channel during Spring tides in the summer of 2021, at a location designated as TCE indicating Tidal Channel East. The boat repeatedly traversed each channel from one bank to the other, collecting data during each transect crossing. The dates and times of the transect measurements were chosen to cover as much of a full diurnal tidal cycle as possible, subject to logistical and safety constraints. ADCP data were recorded and initially reviewed using WinRiver II version 2.23. 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. All datafiles were retained.

Process_Description:
Discharge data were collected using a boat-mounted Teledyne RDI RiverPro 1200 kHz acoustic Doppler current profiler (ADCP), in three tidal channels, designated as TCM, TCE, and TCW indicating Tidal Channel Main, and smaller channels East and West further from the bay. The boat repeatedly traversed each channel from one bank to the other, collecting data during each transect crossing. The dates and times of the transect measurements were chosen to cover as much of a full diurnal tidal cycle as possible, subject to logistical and safety constraints. ADCP data were recorded and initially reviewed using WinRiver II version 2.23. WinRiver II is available at ttps://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. Designation of tidal creek banks as "left" and "right" conform to the USGS Water Resources convention as with reference to the downstream direction. Downstream is defined as towards the bay.
Process_Date: 20220104
Process_Step:
Process_Description:
Data were post-processed using QRev version 4.37, a program developed by the USGS Office of Surface Water to compute moving-boat ADCP discharge. 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. A constant respresentative value for salinity was applied to each measurement file. Variations in salinity affect the estimate of speed of sound in water, which is used in computing discharge. Field measurements of salinity and temperature collected with an RBR Maestro CTD are available in a separate section of this data release and may be used to reprocess and improve the discharge measurements. 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. Data from incomplete transects have not been processed with QRev. However, these files have been retained in the .pd0 binary files. The following data transects were not processed: on June 30, 2021 transect 17, on July 27, 2021 transect 19, and on January 3, 2022 multiple transects (1,5,48,64-66, 71,72). Additionally, time internal to the raw data files collected January 3, 2022 at TCW have incorrect time due to an ADCP clock reset error. Corrected time in UTC is recorded time - 86.734 days (86 days 17 hours 37 minutes). The data were exported from QRev as a .mat file using bottom-track (BT) navigation reference.

Overview_Description:
Entity_and_Attribute_Overview:
This dataset consists of discharge measurements collected using a Teledyne RD Instruments RiverPro ADCP (Teledyne RD Instruments, 2024). All data were collected with Teledyne RD Instruments WinRiver II version 2.23 (Teledyne RD Instruments, 2020) and processed with QRev version 4.37 (Mueller, 2016). Due to the complexity of an ADCP data file and the various algorithms applied to compute the streamflow from ADCP data, these data are most useful in either 1) their original raw data format which can be opened and processed in either WinRiver II or QRev or 2) their processed format which can be opened and processed by QRev or opened by Matlab or any software that can read Matlab formatted files. Both WinRiver II and QRev are distributed free. This dataset is in the form of a zip file, wt_adcp_transects.zip. The data are divided into folders based on location and acquisition time, and further divided by software association. The top-level folder naming convention consists of WT_Season_Location_X where WT indicates Whales Tail Marsh. The Season is specified as Summer or Winter, the Location is TCM, TCE, or TCW for Tidal Creek Main, East, or West, and where TCE summer survey were repeated, the survey index is appended. Each of these folders contains two subfolders: QRev_Files and WinRiver_II_Files. The WinRiver II files consist of: 1. .mmt file: XML configuration file used by WinRiver II for setup, specific measurement data entry, and filenames of the raw transect data files (pd0) 2. .pd0 files: raw binary data collected by WinRiver II. The format for these files is defined in Teledyne RD Instruments (2020). The QRev files consist of: 1. .mat files: saved data processed by QRev. These files can be opened and processed by QRev or loaded into Matlab or software that can read Matlab formatted files. The variable definitions are documented in Mueller (2016). 2. .xml: summaries of the data processed by QRev. The variable definitions are documented in Mueller (2016). Refer to the README-zipped-file-explanation.txt file in this directory for further information.
