Part of a long-term monitoring program at biennial intervals in which corals, algae, fish, and other macro invertebrates are co-sampled along the same set of transect lines.
Observations at each site were made by three divers who are experts in fish taxonomy. The team of three REA fish divers rotated roles with two divers performing belt-transect surveys and one diver performing stationary point counts at each survey site. Observations were periodically checked during the expedition for consistency between divers, and little discrepancy was ever noted between divers. It should be noted, however, that this data set is quite large, and probably includes typographical or other errors that might be discovered at a future date.

The survey sites were selected to be representative of the coral reef habitats at this reef system. Efforts were made to include broad spatial coverage of the reef area, but weather conditions or other environmental constraints may have precluded the team from surveying windward or exposed sites.
The same methods of data collection were used at each of the sites surveyed at this location, and were conducted by the same scientists. Periodic examination of the data through the duration of the trip showed no signs of diver bias or other discrepancies.
Are there legal restrictions on access or use of the data?
