Various parameters such as substrate, coral, and coralline algae types and percent bottom coverages of each were quantified using the Linear Transect Method (LTM) or Line Intercept Technique along 30 m transects at typically -3 or -20 meters depth. Various derived parameters such as abundance and diversity were also determined. Purpose: Support research in sedimentology, sea level history, and reef development.

Identified and measured the length of each substrate type that intersected a 30 m measuring tape, generally following depth contours. Sites were chosen to characterize dominant and transition settings inferred from the hydrographic and MSS surverys, and to randomly fill a 15" latitude-longitude grid over the reef. Measured each change in substrate with an accuracy of 0.2 m (0.6% substrate cover) and determined from replicate surveys that precision was reproducible at 1-3% substrate cover. Additional notes: Minimum mapping unit = 20 cm. Location data based on WGS84. Depth error = +/- 1 meter. Rugosity calculated by dividing lateral (basal) distance of chain draping susbtrate by total length of chain. Substrate Type (% of bottom) is cover of individual substrate types divided by length of transect (30 m). Coral Cover (% of bottom) is cover of individual coral types divided by length of transect (30 m). Growth form (% of bottom) is cover of individual coral growth forms divided by length of transect (30 m). Coral community (based on 100%) is cover of individual coral species (ecotypes) divided by total cover of live coral. Coral morphology (based on 100%) is cover of individual coral colony morphologies divided by total cover of live coral. Cor-algae cover (% of bottom) is cover of individual coralline algae types divided by length of transect (30 m). Dead coral (% of bottom) is cover of dead coral types divided by length of transect (30 m). Dead community (based on 100%) is cover of dead coral species divided by total cover of dead coral. Colony Counts (by ecotypes) is number of individual coral colony types by species (ecotypes) along transect. Colony Counts (by growth form) is number of individual coral colony types (by morphology) along transect. Counts - Summary is total numbers of colonies by species and ecotypes. Abundance (by ecotypes) is number of individual coral colonies by species (ecotype) divided by total number of coral colonies along transect. Abundance (by growth form) is number of individual coral colonies by colony morphology divided by total number of coral colonies along transect. Diversity (based on cover) is Shannon-Weiner diversity index based on cover. Diversity (based on abundance) is Shannon-Weiner diversity index based on abundance. Mean Colony Size (ecotype, m) is mean size of coral colony by species (ecotype) along X (horizontal) axis." Mean Colony Size (growth form, m) is mean size of coral colony by colony morphology along X (horizontal) axis. Maximum Colony Size (ecotype) is maximum colony size by species (ecotype) along transect. -9999 is missing data or no data flag.
