Belt transects along 2 consecutively-placed, 25m transect lines were surveyed at 50-cm intervals as part of Rapid
Ecological Assessments conducted at 18 sites at Johnston Atoll in January, 2006 from the NOAA vessel Hi'ialakai
(HI06-01). Raw survey data included percent cover of benthic parameters, including live coral, dead coral, carbonate
pavement, sand, coral rubble, fleshy macroalgae, crustose coralline algae, and other sessile invertebrates along the
two transect lines. In addition, an area of 1-2m on each side of each transect was surveyed; within this area, each
coral colony was inspected and every diseased/afflicted colony identified to the lowest taxonomic and type of
affliction recorded.
Part of a biennial monitoring program in which corals, algae, fish, and other macroinvertebrates are co-sampled
along the same set of transect lines
Maximum depth was 18 meters.

Observations were made by a single diver who is an expert in coral diseases. The benthic cover and disease assessment
surveys are conducted one time per site per survey year; it is not replicated.
The same methods of data collection were used at each of the sites surveyed
at this location, and were conducted by the same scientist (Vargas-Angel).
The majority of surveys were conducted in the lagoon due to inclement sea conditions in other habitats.

Instrument parameters
As a diver swam along the transect line, he inspected the benthic elements falling directly underneath each 50-cm
mark on the transect line. Each such element was tallied under the following scheme: live coral, dead coral, carbonate
pavement, coral rubble, sand, rock, algae, invertebrate, and other. Live benthic elements including coral, algae,
and invertebrates were identified to the lowest taxonomic level possible. At the end of this examination , the diver
also surveyed an area of 1-2 m on either side of each transect lines, along which each coral was inspected and
every diseased colony identified to the lowest taxonomic and type of affliction recorded.
