Reef composition surveys on reefs in Moorea, French Polynesia from 2003-2017

Expand/Collapse All

Description

Reef composition was surveyed on the reefs used in the long-term removal study during the years 2012-2017.

These data are meant to provide contextual information for how vermetids affect reef communities.

Long Term Vermetid Removal (LTVR) Reef sites in this project are manipulated reefs characterized in the Long Term Reef Physical Characteristics dataset.

Reefs labeled "TOW" in this dataset, numbered 129-144, are a subset of a larger number of Long Term Reefs (LTR) that were monitored as part of the project "Cryptic density dependence: the effects of spatial, ontogenetic, and individual variation in reef fish" beginning in 2003. This long term study continues to monitor those reefs in addition to reefs 193-198 starting in 2012. Data for these reefs between the years 2003 and 2009 can be found on the project site http://www.bco-dmo.org/project/540423.

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

Methods & Sampling

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. For each reef there are at least 50 fixed-point contacts. 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

Entries with a question mark following the point contact value likely indicate uncertainty during data transcription.

Data 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

BCO-DMO Processing Notes
- Generated from original file "LTVR_PercentCoverPointContact.csv" contributed by Rebecca Atkins
- Parameter names edited to conform to BCO-DMO naming convention found at Choosing Parameter Name
- Any blank rows removed
- Site "TOE" in original .csv file replaced with "TOW" per feedback from PI

Data version 2: 2018-01-26 replaces data version 1: 2016-05-23. Data range extended to 2017.

BCO-DMO Data Manager Processing Notes for version 2018-01-26:
* Added a conventional header with dataset name, PI name, version date
* Modified parameter names to conform with BCO-DMO naming conventions
* converted commas to semicolons to support csv export.
* PSPSMOO PSPRIDG PSPCOLUM PRUS MONTIP POC ACROP OTHCORAL blanks changed to 0s.

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.
