During the cruise, 16 REA sites were surveyed at Johnston Atoll in the Pacific Remote Island Areas. Benthic biologists from NOAA's Coral Reef Ecosystem Division conducted Line Point Intercept surveys to quantitatively document the benthic cover at pre-determined long-term monitoring REA sites. Two linear 25M transects were surveyed with a 5M inter-transect region between the end of Transect 1 and the start of Transect 2. The LPI diver determines the benthic composition at 20cm intervals for a total of 125 data points per transect. All living benthic elements (e.g., coral, algae, and other invertebrates) were identified to the lowest taxonomic level possible, often substituting functional group categories for turf algae and crustose coralline algae when identification in the field was extremely difficult. In cases where the substrate is bare or covered with turf algae, the substrate composition is also noted as either sand, rock, rubble, carbonate pavement, or dead coral. These data allow for the assessment and monitoring of species composition and abundance and provide the basis for computing quantitative estimates of percent cover at higher taxonomic levels like functional group (live Coral, macroalgae, turf algae) or on a finer taxonomic resolution such as genus level. Part of a long-term monitoring program at biennial intervals which documents the state of the reefs.

The same methods of data collection were used at each of the sites surveyed at this location, and were conducted by the same scientist. REA surveys are investigations that provide a high degree of taxonomic resolution for coral, algae, and other macroinvertebrate communities. The majority of REA surveys were conducted along the forereef slopes of individual islands at depths between 10 and 20 m. However, additional habitats including lagoonal-type patch reef and offshore oceanic banks were surveyed when they existed. During REA surveys, biological assessment teams follow highly structured protocols that are repeated at each REA site. Upon arrival at an REA site, divers entered the water and deployed two 25M transect lines which are shared with coral surveys that gather community structure, diversity, recruitment, and health status data. The sampling effort takes between 60 and 80 min to complete. The selection of REA sites was made in close consultation with Coral Reef Advisory Group (CRAG) and local agencies. Factors considered during REA site selection included: (1) ensuring a range of sample sites representative of the benthic and reef fish habitats around each island; (2) selecting a mixture of sites within and outside of marine protected areas; (3) selecting a mixture of both 'impacted' and 'least impacted' sites; (4) selecting some sites adjacent to local villages, and (5) selecting a number of sites that could be compared to and complement previous assessment and monitoring work as well as future coral reef monitoring proposed by CRAG and local agencies. It is important to note that access to REA sites can be limited by wave exposure, weather conditions, and other environmental factors such as currents, which can affect the ability to resurvey sites between years. Transect placement was guided by: (1) a focus on hard-bottom communities; (2) deploying lines along an isobath to the extent possible at each site, and (3) laying the transect lines into the prevailing current. annually This metadata was automatically generated from the Content Standard for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2016-01-11 version of the FGDC RSE to ISO 19115-2 transform.
