Hawaii Coral Reef Assessment and Monitoring Program (CRAMP): Benthic Data from 2002-2004 (NODC Accession 0002313)
This dataset consists of CRAMP surveys taken in 2002-2004 and includes quantitative estimates of substrate and species type. From the data percent coverage of a given species can be estimated. 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 video transects or photoquadrats however these have been provided to NOAA separately. Fish transects were discontinued after 2002. In 2002, there were 57 lines surveyed at 28 sites. Due to funding cuts, the number of surveys dropped in 2003 and 2004. There were 8 surveys provided to NODC for 2003 and 5 in 2004. A few more surveys during this time period could become available at a later date. Surveys typically consist of shallow (~3m) and deep (~10m) lines.
