The zone for the given SITE (Forereef, Backreef, Protected Slope, Lagoon).

Classification of depth (shallow, mid, deep) based on midpoint between minimum and maximum depths of replicates at this site. Shallow: >0-6 m, Mid: >6-18 m, Deep: >18-30 m.

Unique identifier created each time a SITE is surveyed on a DATE_.

Local date the survey was conducted.

4-digit year the survey was conducted (DATE_).

Initials of diver that conducted the survey.

Unique identifier for the replicate sample within a Fish REA survey.

Fish method employed: stationary point count (nSPC).

Flag to indicate photographer of benthic photos. Two divers simultaneously conduct a survey at a site (indicated by the initials of the observer in the DIVER field), only one of which captures the benthic photos. Value -1 indicates the photographer.

Flag to signify whether replicate was for training purposes. Value -1 indicates the replicate was for training.

Sponge cover (0-100%). Sum of benthic composition categories equals 100. No longer collected as of 2016 surveys; pooled into OTHER.

Other benthic composition value (0-100%). Sum of benthic composition categories equals 100. Turf algae, tunicates, zoanthids, corallimorphs, clams, cyanobacteria, soft coral, and sponges are pooled into this category as of 2016 surveys.

Other benthic composition type. No longer collected as of 2016 surveys.

4-letter code for TAXONNAME. Required.

Scientific name of observed organism to the finest taxonomic resolution that divers can identify a fish to, usually to species (see RANK). Required.

Common name (from FishBase).

Common name of all families.

Taxonomic classification: Family of observed organism (TAXONNAME).

Taxonomic classification: the true scientific name (genus and species) of the observed organism (TAXONNAME). If NULL, organism not identified to species taxonomic level (see RANK).

Lowest defined rank in taxonomic hierarchy.

Trophic level: APEX (apex predator), Cor (corallivore), H (herbivore), MI (mobile invertivore), Om (Omnivore), Par (parasite), Pisc (piscivore), Pk (planktivore), SI (sessile invertivore), X (if unidentified fish), Z (zooplantivore).
