Methods & Sampling

Chunks of rubble containing vermetids at a site near the reef crest were collected. Researchers targeted a range of sizes, and attempted to collect haphazardly from the site, removing the snail and its entire shell.

In the lab, the shell aperture (maximum internal diameter)was measured, then vermetids were extracted from the shell, their operculums were measured and their wet weight (blotted dry) was recorded. Data were collected similarly in 2008 and 2015 by Tom Frazer and Jeff Shima.

Data Processing Description

Size data were converted into log in base 10.

BCO-DMO Processing:

added 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'.

Instruments

Diving Mask and Snorkel

Supplied Name: snorkel

Supplied Description:

Researchers snorkeled to the reef crest.

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.
