Description

Pomancentrids identity, size and abundance were enumerated around 192 patch reefs. Data were collected in 2003-2006, 2009, 2012, and 2014 at 192 reefs. Beginning in 2012, reefs 129-144 and added reefs 193-198 were manipulated for a project studying the effects of vermetid removals; information pertaining to this manipulation can be found in the project “Spatial patterns of coral-vermetid interactions: short-term effects and long-term consequences”. All data collected on reefs 129-144 and 193-198 beginning in 2012 can also be found under that project. In 2012, additional data were collected – the number of vermetids on each patch reef at the time of this survey. Common Pomancetrids were recognized and size class determined. These data are part of the larger data set describing the biological and physical conditions of the 192 reefs. Together all of these data provide information about the factors that may influence (or be influenced by) Thalassoma and Vermetid.

Location: Moorea, French Polynesia (17.48 degrees S, 149.82 degrees W)

Methods & Sampling

Dataset acquisition description

Sampling and Analytical Methodology:
A single snorkeler approaches one of the 192 patch reefs (for size of reef, see the physical characteristics file). He or she swam around the reef, recognized and estimated the size of all the common Pomacentrids in broad size categories depending on the species. The rare species were just counted.

Materials: snorkel and dive slate

Instruments

Diving Mask and Snorkel

Supplied Name: Mask and snorkel

Supplied Description:

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.

Measuring Tape

Supplied Name: Transect Tape

Supplied Description:

Materials: transect tape and slates

Instrument Type

Generic Name: Measuring Tape

Generic Description:

A tape measure or measuring tape is a flexible ruler. It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear-measurement markings. It is a common tool for measuring distance or length.

Underwater Writing Slate

Supplied Name: Slate

Supplied Description:

Materials: transect tape and slates

Instrument Type

Generic Name: Underwater Writing Slate

Generic Description:

Underwater writing slates and pencils are used to transport pre-dive plans underwater, to record facts whilst underwater and to aid communication with other divers.
