Description:

Abstract:

Suspended-sediment transport is a critical element governing the geomorphology of tidal marshes. Marshes rely both on organic material and inorganic sediment deposition to maintain their elevation relative to sea-level. In wetlands near the Blackwater National Wildlife Refuge, MD, portions of the salt marsh have been subsiding relative to sea level since the early 20th century. Other portions of the marsh have been successful at maintaining elevation. The USGS undertook measurements of suspended-sediment concentration in the tidal channels in order to understand the magnitude of suspended-sediment concentrations, the sediment-transport mechanisms, and relative differences between the two areas of the marsh. We deployed optical turbidity sensors and acoustic velocity meters at multiple sites over two periods in 2011. The time-series of oceanographic data collected during those field studies, including velocity, depth, turbidity, salinity, water temperature, and pH are presented here. For more information on the field operations associated with data collection: https://cmgds.marine.usgs.gov/fan_info.php?fan=2011-017-FA; https://cmgds.marine.usgs.gov/fan_info.php?fan=2011-029-FA; https://cmgds.marine.usgs.gov/fan_info.php?fan=2011-044-FA; https://cmgds.marine.usgs.gov/fan_info.php?fan=2011-050-FA;

Purpose:

This dataset provides measurements from an estuarine field study that occurred in the spring and fall of 2011. The data were collected in support of efforts to model the circulation, nutrient and sediment fluxes in the marsh. The background and experimental setup are described in the open file report "Summary of Oceanographic and Water-Quality Measurements near the Blackwater National Wildlife Refuge, 2011", https://pubs.usgs.gov/of/2012/1099/. The locations, deployment depths, sensor type and parameters measured during the deployment are shown in the table displayed by the Basic Sampling Interval link ( https://stellwagen.er.usgs.gov/bw2011-a.html ). The basic sampling interval data files are provided at the rate at which the sensor made observations- no temporal averaging, filtering or subsampling was done. The data files are accessible by clicking the file name.

Data_Quality_Information:

Logical_Consistency_Report: Data are logically consistent
Completeness_Report:

The data have been edited to remove outlying points and data recorded when the instruments were out of the water (before and after deployment or at low tide).

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The deployment locations were measured by a hand-held GPS (Garmin GPS C76).

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

The sensors were mounted on poles or the channel bottom in less than 5 meters of water. The tidal range here is ~0.5 meters so as the tide changes, so will the relative depth. Height above the bottom will not change and be accurate to within 5cm, while depth may change significantly.

Process_Description:

FIELD PROGRAM: Between March and May 2011, continuous measurements were collected at three sites in the Blackwater complex (moorings 903, 904, 905) and three sites in the Fishing Bay complex (moorings 906, 907, 908). Identical pole-mounted YSI sensors were deployed at all six sites. Parameters measured include water level, salinity, temperature, dissolved Oxygen, pH, and turbidity. Between September and October 2011, continuous measurements were collected at two sites in the Blackwater complex (moorings 916, 917) and two sites in the Fishing Bay complex (moorings 915, 918). A pole-mounted YSI and an upward looking current profiler were deployed at sites 915 and 916, with a pole-mounted turbidity sensor deployed at 917 and 918. Parameters measured include water level, water velocity, salinity, temperature, dissolved Oxygen, and turbidity.

Process_Description:

DATA PROCESSING Data processing was conducted using the proprietary software for each instrument, and (or) specialized software developed by the USGS. The proprietary software was often used to download data from the instruments and export the data to ASCII-files. Post-processing of the raw binary or ASCII files was accomplished using USGS software developed in the MATLAB (http://www.mathworks.com/) programming language. As part of the processing, instrument-specific formats were converted to the EPIC-standard NetCDF format (http://www.pmel.noaa.gov/epic/) and scientific units. Data were carefully checked for inconsistencies, time drift, and other problems and then edited if needed. The beginning and end of each data series were truncated to remove data collected out of water. After final editing, the best basic version of the data file that includes all variables recorded at the basic sampling interval (the fastest rate at which the sensor sampled) is published.

Process_Description:

Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Added online link to experiment page. Fixed online link to cross-reference. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
