Coastal Hydrodynamics and Sediment Dynamics (CHSD)
All samples contained within (37º39’N, 76º54’W), (37º16’N, 76º20’W), (37º8’N, 76º24’W), (37º34’N, 76º0’W)
The MUlti-Disciplinary Benthic Exchange Dynamics (MUDBED) project was a >15-year collaboration of multiple VIMS scientists in characterizing sediment transport within the York River estuary.
The extensive MUDBED data set hinges around the deployment of acoustic Doppler velocimeters (ADV) tripods in the Gloucester Point and Claybank regions of the York River estuary. These deployments usually lasted approximately 3 months, during which calibration cruises, sediment surveys, and other tripod and tower deployments occurred. The calibration cruises consisted of a water column profiler equipped with and ADV, CTD, and LISST, among other instruments. The sediment surveys included measurements of grain size distribution and other sediment properties, including sediment erodibility. Various other instruments such as LISSTs, AWACs, and PCADPs were also deployed on similar tripod structures for prolonged amounts of time. Lastly, the CHSD tower piling in the York River, served as a stationary platform for deployments of stacked ADVs, LISSTs, and light sensors. The attached files include a master sampling spreadsheet as well as a sampling timeline, to serve as a guide to navigating the large data set. Each folder in the dataset represents a single tripod/tower deployment or sampling cruise. Each folder includes a string to represent the date of deployment/sampling. “YR” (representing “York River”) followed by six numbers which represent the date of sampling in the format YYMMDD. For example, August 31, 2014 would be YR140831. All data for the MUDBED project can be accessed by starting at https://scholarworks.wm.edu/yorkriverdata/ and then entering the appropriate deployment/sampling code (such as YR140831). List of files: • MUDBEDProject_SamplingLog – This Excel file includes all sampling from the MUDBED project. The excel file includes multiple tabs. The Gloucester Point Log, Claybank Log, and Yorktown Log tabs divide all sampling by location in chronological order. Each type of deployment/cruise are also separated into individual sheets (Longitudinal Cruises, Calibration Cruises, Sediment Surveys, Tripods, and Tower). Each sheet shows which instruments were used or data that was collected during the individual deployment/cruise. Different types of deployments/cruises are color-coded with tripod deployments in blue, tower deployments in purple, sediment surveys in red, calibration cruises in green, and longitudinal cruises in orange. The names of the ScholarWorks entry for each deployment/cruise are also included.
• SamplingTimeline – This Excel file plots all of the deployment/cruises on a timeline to determine which cruises and surveys occurred during each deployment. There are timelines included for the Gloucester Point and Claybank sampling areas.
