As part of the mulit-disciplinary Carolinas Coastal Change Processes Project, we are examining the interactions between oceanographic forcing, geologic conditions, and the resulting changes to topography in the inner shelf, nearshore, and subaerial beach regions. This dataset presents data from an oceanographic field study from January - May 2009 to investigate processes that control the dynamics of sediment transport at Diamond Shoals, NC. For more information see https://www.usgs.gov/centers/whcmsc/science/coastal-change-processes, https://cmgds.marine.usgs.gov/fan_info.php?fa=2009-003-FA and https://cmgds.marine.usgs.gov/fan_info.php?fa=2009-014-FA. Purpose: This dataset provides information for an oceanographic field study that occurred from January - May 2009 to investigate processes that control the sediment transport dynamics at Diamond Shoals, NC. Tripods were deployed at three sites along the outer perimeter of the shoal. Mounted on the tripods were instruments to measure surface waves, pressure, current velocity, bottom turbulence, suspended-sediment profiles, and sea-floor sand-ripple bedforms; one tripod also held a visual camera system. The measurements will be used to explore the oceanographic and sediment-transport processes responsible for maintaining the and distributing sand on the shoal. The background and experimental setup are described in the open file report "Carolinas Coastal Change Processes Project Data Report for Observations near Diamond Shoals, North Carolina, January-May 2009", on line at: https://pubs.usgs.gov/of/2011/1156/. The locations, deployment depths, sensor type and parameters measured during the deployment are presented in the table displayed by the Basic Sampling Interval link on the stellwagen server ( https://stellwagen.er.usgs.gov/diamondshoals-a.html ).

Additionally, one tripod (North Flobee) tipped over near mid-April. The velocity and other data made unusable by this tilt were removed. The Tip Micropod was deployed deeper than planned, resulting in velocity depth bins that did not reach the surface, thus no wave data was produced at this site. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The mooring deployment locations (latitude and longitude) were recorded based on the R/V Connecticut's onboard GPS. Specification are available at http://marinesciences.uconn.edu/mstc/vesselops/rvct/. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Bottom-mounted sensors have instrument_height attributes (meters above bottom) measured prior to deployment. The sensor height above bottom is accurate to within 1 cm, but the depth (representing the initial measurement depth) is only accurate to about 1 meter due to tidal fluctuations and use of nominal water depth. If the sensor acquires data in bins by depth (ADCP, PCADP), those depths are accurate to a few centimeters relative to each other. Sedimentation or scouring around the platform may change the vertical position over the course of a deployment by as much as 20 cm. The data are not adjusted to reflect any temporal changes in elevation of the sensor.

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. Most MATLAB M-files used for post-processing are available via the World Wide Web (WWW) (links provided). Those that are not available via the WWW are included in this report (see the Matlab m-files page available in https://pubs.usgs.gov/of/2011/1156/ ). Data were first decoded and calibrated from instrument-specific formats and units to the EPIC-standard NetCDF format (http://www.pmel.noaa.gov/epic/) and scientific units. Data were carefully checked for instrument malfunctions and then edited. The beginning and end of each data series were truncated to remove data collected out of water. The data were carefully checked at each stage of processing. After final editing, the best basic version of the data file includes all variables recorded at the basic sampling interval. Best basic versions of the data in NetCDF are provided. These data have been edited to remove outlying points and data recorded when the instruments were out of the water before and after deployment. Biological fouling often degrades acoustical and optical data after several months of deployment. Organisms grow on the instrument transducers and gradually block acoustical pulses and light transmission, which results in a gradual upward drift of the beam attenuation coefficient. Care has been exercised to remove most data that have been affected by biofouling. There was significant tilt of the ADCP at the North Flobee site when the tripod tipped in mid April. The velocity data have been removed for this latter portion of this ADCP file, but pressure and temperature data are available for the whole period. A change in the deployment depth at the Tip Micropod site resulted in data that did not reach the surface for that site. All data should be used and interpreted with care. Process_Date: 2009 Process_Step: 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.). Fixed the online link to a 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.
