资源简介：
This dataset consists of CRAMP Rapid Assessment Transect surveys taken in 2001-2004 and includes quantitative estimates of substrate type and species. The types and coverages were derived objectively from photographic images using PhotoGrid, a software package which analyzes random points on images of coral reefs and substrate. This dataset does not include the images from the transects, which have been provided to NOAA separately.
In 2002, there were 57 lines surveyed at 28 sites. Due to funding cuts, the number of surveys dropped to 8 in 2003 and 5 in 2004. Surveys typically consist of shallow (~3m) and deep (~10m) lines. This dataset contains surveys from 20 sites.
