Oyster density of restored reef edge/interior in Quonochontaug Pond, RI in May 2019

Abstract:

This dataset represents oyster density measurements of restored reef edge/interior in Quonochontaug Pond, Rhode Island, USA determined by scuba divers in May of 2019. Reef relief and quadrat relief were calculated by subtracting water depth at each quadrat (quadrat relief) or the highest point on the reef (reef relief) from water depth on the adjacent unstructured bottom.

Methods & Sampling

These data were published in Table S1 of Davenport et al., 2022 (Restoration Ecology).

To quantify the observed pattern of higher oyster density around the edges of reefs at Quonochontaug Pond, Rhode Island, USA, (41.3 N, 71.7 W) we surveyed oyster density and reef relief in May 2019. Divers haphazardly placed 0.25 m² quadrats on each oyster reef and excavated all live and recently dead oysters (N = 3-5 quadrats per reef on each of edge and interior). Live oysters were counted in the field before returning them to the reef in the same location where they were collected. Top valves were removed from recently dead oysters (open oysters with both valves present, but no live tissue) to confirm they were dead before replacing them. Divers also measured water depth with a meter stick at each quadrat, at the highest point on each reef, and at the unstructured bottom adjacent to each reef. Reef relief and quadrat relief were calculated by subtracting the water depth at each quadrat (quadrat relief) or the highest point on the reef (reef relief) from the water depth on the adjacent unstructured bottom.

Data Processing Description

BCO-DMO Processing:
- Converted dates to YYYY-MM-DD format;
- Adjusted field/parameter names to comply with BCO-DMO naming conventions;
- Added a conventional header with dataset name, PI names, and version date;
- Values in the column "quad_rel" were converted from meters to centimeters (as integers) as requested by data provider.

Instruments

ruler

Supplied Name: meter stick

Supplied Description:

A meter stick was used to measure water depth.

Instrument Type

Generic Name: ruler

Generic Description:

A device used for measuring or for drawing straight lines, consisting of an elongated piece of rigid or semi-rigid material marked with units for measurement. Device that allows one or more physical dimensions of a sample or specimen to be determined by visible comparison against marked graduations in units of measurement of dimension length.

Self-Contained Underwater Breathing Apparatus

Supplied Name: SCUBA

Supplied Description:

Instrument Type

Generic Name: Self-Contained Underwater Breathing Apparatus

Acronym: SCUBA

Generic Description:

The self-contained underwater breathing apparatus or scuba diving system is the result of technological developments and innovations that began almost 300 years ago. Scuba diving is the most extensively used system for breathing underwater by recreational divers throughout the world and in various forms is also widely used to perform underwater work for military, scientific, and commercial purposes.
