Description

This dataset contains eastern oyster (Crassostrea virginica) density and lengths. Oyster density sampling was conducted at reefs within the Rachel Carson National Estuarine Research Reserve, Back Sound, North Carolina in 2010 and 2014. Also included in this dataset are reef elevation and exposure data that was generated from laser scans and water level loggers (see related dataset list for more details).

Other Back Sound datasets in this project:
Laser scans
Water level
Reef elevation, exposure, and vertical change
Laser scan, density, and GPS grid sampling information

These data are published in:

Ridge, J. T., Rodriguez, A. B., Fodrie, F. J., Lindquist, N. L., Brodeur, M. C., Coleman, S. E., ... & Theuerkauf, E. J. (2015). Maximizing oyster-reef growth supports green infrastructure with accelerating sea-level rise. Scientific reports, 5. doi: 10.1038/srep14785

Methods & Sampling

Locations (UTM, Latitude, and Longitude) for natural reef sampling are the quadrat locations. Locations provided for constructed reef sampling are broader site locations.

See Ridge et al. 2017 for more sampling methodology details.

Data Processing Description

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* blank values replaced with no data value 'nd'
* added site locations in decimal degree format (lat,lon) from provided UTM coordinates
* length, exposure, and density rounded to two decimal places
