Popis
Belt transects along 2 consecutively-placed, 25m transect lines were surveyed as part of Rapid Ecological Assessments conducted at 2 sites at Necker in the NW Hawaiian Islands (NWHI) during 1 September - 4 October 2006 in the NOAA Hi'ialakai Reef Assessment and Monitoring Program (RAMP) Cruise (HI0611). 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, 0.5 or 1 m on each side of the transect lines was included in the belt (for a total of 25-100m2 per site).
