Densities of corallivorous gastropods in 36 cm × 36 cm plots on a fringing reef in Fiji

Expand/Collapse All

Description

We surveyed corals in each of our 48 plots for the presence of corallivorous gastropods (e.g. Drupella spp.).

These data are depicted in Supplemental Figure 5 of Clements and Hay (2019).

These data was also funded through:
National Institutes of Health (2 U19 TW007401-10)
Teasley Endowment to the Georgia Institute of Technology

Methods & Sampling

These are the raw count data, which were recorded in the field.

Data Processing Description

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- appended the latitude and longitude coordinates to the data as supplied in the accompanying metadata

Instruments

Diving Mask and Snorkel

Supplied Name: snorkel

Supplied Description:

These data were collected near shore via snorkel.

Instrument Type

Generic Name: Diving Mask and Snorkel

Generic Description:

A diving mask (also half mask, dive mask or scuba mask) is an item of diving equipment that allows underwater divers, including, scuba divers, free-divers, and snorkelers to see clearly underwater.

Snorkel: A breathing apparatus for swimmers and surface divers that allows swimming or continuous use of a face mask without lifting the head to breathe, consisting of a tube that curves out of the mouth and extends above the surface of the water.

Parameters

Date and time formats are described in python strftime() syntax.
