Description
Belt transects along 2 consecutively-placed, 25m transect lines were surveyed as part of Rapid Ecological Assessments conducted at 10 sites around Ofu and Olosega Island in American Samoa from 28 February to 05 March 2008 aboard the NOAA ship Hi'ialakai during the Reef Assessment and Monitoring Program (RAMP) Cruise HI0802. Raw survey data included species presence and relative abundance, colony counts and size classes by genus, and determination of benthic cover using the line-intercept method. Depending on colony density, 1 m on each side of the transect lines was included in the belt (for a total of 25-50m2 per site).
