Methods & Sampling

Dataset acquisition description

We sampled 30 intertidal oyster reefs varying in complexity and height within North Inlet during May and June 2014. Sampling was conducted during low tide. Reefs were chosen based on reef height (range 5–25 cm) in order to ensure relatively even sampling across reefs of different qualities; thus, this data set does not represent the natural distribution of reef heights at our site. We determined reef height using the average of 10 measurements taken at random locations within each reef, each one measuring the height from the surface of the mud to the top of the oyster shells. The quality of reefs sampled was randomized through time so that there was no trend between reef height and Julian day in our sampling. Within each reef, we conducted sampling within three haphazardly placed 1 m^2 quadrats. From each quadrat, we counted the number of large and small bivalves (C. virginica and B. exustus) within two 0.5 m2 quadrats on each reef. We defined small bivalves to be those <4 cm in shell length.

Data Processing Description

Dataset Processing Description

Raw data are presented.

BCO-DMO Processing:

- added conventional header with dataset name, PI name, version date, reference information
- renamed parameters to BCO-DMO standard
- converted lat and lon from degrees, minutes and seconds to decimal degrees
- reformatted date from m/d/yyyy to yyyy-mm-dd
