Description:
Abstract:
Files contain hydrodynamic and sediment transport data for the location and deployment indicated. Time-series data of water depth, velocity, turbidity, and temperature were collected in San Pablo Bay and China Camp Marsh as part of the San Francisco Bay Marsh Sediment Experiments. Several instruments were deployed in tidal creek, marsh, mudflat, and Bay locations, gathering data on water depth, velocity, salinity/temperature, and turbidity. Deployment data are grouped by region (Bay channel (main Bay), Bay shallows, tidal creek, or marsh/mudflat/upper tidal creek). Users are advised check metadata and instrument information carefully for applicable time periods of specific data, as individual instrument deployment times vary.
Purpose:
Data from these experiments will be used to investigate the spatial and temporal variation in suspended sediment transport at the marsh boundary in order to better inform predictions of marsh resilience, and offer more complete characterizations of sediment transport and conditions within this unique environment. From these data, coincident wave height/period can be calculated for use in sediment transport investigations.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: No formal attribute accuracy tests were conducted.
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 metadata for each part of this data release 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, as the sediment tends to be very compacted in the study area, and analysis of distance to bed data did not show gradients over the duration of deployment. The measuring tools used to mount the instruments onto the platforms have a resolution of 1 cm resulting in an uncertainty of 2 cm.

Process_Date: 20160621
Process_Step:
Process_Description:
Data were processed using the instrument manufacturers' software packages. 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 were identified by 1) the deployment and recovery times, 2) pressure readings equal to or less than 1 m of water, 3) amplitude or correlation values outside of predetermined quality thresholds for the ADCP. Data near the surface with variable side lobe interference were retained.

Process_Description:
Data files were named with a convention that uses a 12- to 13-digit alpha-numeric code; zip files use an abridged eight-digit code. The first three characters for this dataset are for the deployment name (CHC for China Camp measurements including all measurement locations from Bay channel stations to Tidal Creek stations; abridged deployments with measurements taken only at Bay Shallows stations begin with 'SP' followed by A, B, C, or D to denote chronological occurrence). The fourth and fifth positions represent the calendar year in which the first data point in the file was taken (13, 2013; 14, 2014; 15, 2015; 16, 2016). The sixth through eighth positions represent the station identification - see the graphic at https://www.sciencebase.gov/catalog/file/get/58458e82e4b04fc80e5233b3?name=SFBayStationLocations.png (all Bay stations) for location information. Zip files use the informative character codes outlined above for positions 1-8; additional character positions provide instrumentation information for the data files only. The ninth and tenth positions are numbers representing the instrument position on the frame (01, 02 or 03), with 01 as uppermost on the frame. Next is a two- to three-character code for the instrument and data type (adv = Sontek ADV; bpr = RBR bursting pressure sensor; ctd = RBR CTD; obs = optical backscatter; lst = LISST; sct = SeaBird seacat CTD; vec = Nortek ADV; wh = RDI ADCP current data; wv = RDI ADCP wave data). Note that some instruments also include additional external sensors. There are an additional two characters for the instruments that collect data in a bursting pattern to indicate if the burst is included in the file or the statistics of the burst; this indicator is omitted if there is no bursting pattern (-b, burst; -s, statistics). Instruments that collect burst data only record the start time of each burst. The bursting time stamp can be generated from the start time, sampling frequency, and number of samples per burst (retrievable in the NetCDF file).
