Description

Reef composition was surveyed on all 192 reefs between years 2003-2005. The Focal Point Contact (Point Contact) method was used to determine the major substrate types that occupy each reef. Beginning in 2012, reefs 129-144 were used for a manipulative experiment; data beginning in 2012 for these reefs can be found in the project “Spatial patterns of coral-vermetid interactions: short-term effects and long-term consequences.” These data are meant to verify visual cover estimates at each reef (found in the dataset “Percent Visual Cover”).

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

Methods & Sampling

Dataset acquisition description

Sampling and Analytical Methodology:
Three transects were laid out over the right, middle and left side of each reef. The diver recorded the substrate every 10 cm, yielding at least 50 fixed-point contacts for every reef. Corals and algae that are commonly observed are divided by genera. Porites spp are further distinguished as ridged, smooth or columnar.

Materials: transect tape and slates

Data Processing Description

Dataset Processing Description

Data Processing:
To obtain “TOTPOINTS”: Sum all species points from the reef.

NA- Not applicable (never recorded) to this data set
NR- Not recorded at certain times throughout the data set

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.
