Description:
Abstract:
Point-count surveys at 50-cm intervals were conducted along 2 consecutively placed, 25m line transect lines, as part of Rapid Ecological Assessments conducted at 6 sites at Johnston Atoll in the Pacific Remote Island Areas (PRIAs) during 24 January - 14 February 2008, aboard the NOAA Hi'ialakai (HI0801) Reef Assessment and Monitoring Program (RAMP) Cruise. Raw survey data consisted of counts of benthic elements, including but not limited to live coral, dead coral, carbonate pavement, sand, coral rubble, fleshy macroalgae, crustose coralline algae, turfalgae, as well as other sessile invertebrates along the two transects. All live benthic elements were identified to the lowest taxonomic level possible. These data provide the basis for computing quantitative estimates of percent live coral cover, as well as percent cover of the different benthic constituents.
Purpose:
Part of a long-term monitoring program at biennial intervals in which corals, algae, fish, and other macroinvertebrates are co-sampled along the same set of transect lines.
Supplemental_Information:
Maximum depth was 16 meters. Benthic cover parameters observed: BenthicCategory BenthicName CORAL Acropora cytherea CORAL Montipora capitata CORAL Montiporaincrassata CORAL Montipora peltiformis CORAL Montipora sp CORAL Pavona varians RUBBLE Rubble SAND Sand TURFALGAE Dead/Turf algae TURFALGAE Pavement/Turfalgae TURFALGAE Rubble/Turf algae

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The benthic cover parameter observations were made by a single diver who is coral reef ecologist. The benthic cover assessment surveys are conducted one time per site per survey year; it is not replicated.
Logical_Consistency_Report:
The same methods of data collection were used at each of the sites surveyed at this location, and were conducted by the same scientist (Bernardo Vargas-Angel).
Completeness_Report:
The survey sites were selected to be representative of the dominant habitats at this reef system. The majority of surveys were conducted in the lagoon due to inclement sea conditions in other habitats.

Process_Description:
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, macroalgae, turfalgae invertebrate, and other. Live benthic elements including coral, algae, and invertebrates were identified to the lowest taxonomic level possible.
