Popis

Belt transects along 2 consecutively-placed, 25m transect lines were surveyed as part of Rapid Ecological Assessments conducted at 6 sites at Jarvis in the Line Islands in March, 2004 from the NOAA vessel Oscar Elton Sette (OES04-04). 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.
