Description:
Abstract:
Belt transects along 2 consecutively-placed, 25m transect lines were surveyed as part of Rapid Ecological Assessments conducted at 12 sites at Johnston Atoll in January, 2004 from the NOAA vessel Oscar Elton Sette (OES04-01). Raw survey data included genus presence and relative abundance, colony counts and size classes, and visual estimation of percent cover. Either 0.5m or 1m on each side of the transect lines were included in the belt (for a total of 50m2 or 100m2 per site), depending on colony density.
Purpose:
Part of an initial assessment in which corals, algae, fish, and other macroinvertebrates are co-sampled along the same set of transect lines

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Observations were made by a single diver who is an expert in coral biology. The population parameter survey is 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.
Completeness_Report:
The survey sites are primarily located within the lagoon, as inclement sea conditions prevented access outside the atoll reef barrier by small boats used as dive platforms

Process_Description:
As a diver swam along the transect line, he inspected the corals whose center fell within a 1m- or 2m-wide belt (i.e., 0.5 or 1m on each side of the transect line, depending on colony density). Each such coral was tallied by genus and classified by its maximum diameter in one of 7 size classes: 0-5cm, 5-10cm, 10-20cm, 20-40cm, 40-80cm, 80-160cm, or >160cm. At the end of this survey, a visual estimation of coral percent cover was made and recorded. Lastly, a larger area around the transect belt was inspected for additional coral taxa that did not occur within the belt; the relative abundance of all corals was qualitatively assessed using the DACOR system (D = Dominant, A = Abundant, C = Common, O = Occasional, R = Rare.
