This dataset consists of CRAMP surveys taken in 2007 from 9 sites on Maui, 3 sites on Molokai, and 1 site on Kauai. Sites typical have two transects along different isobaths, shallow (~3m) and deep (~10m) lines. Quantitative estimates of substrate type and species were acquired. The types and coverages were derived objectively from photographic images using PhotoGrid, a software package which analyzes random points on digital still images of coral reefs and substrate. This dataset does not include the images from the transects, which have been provided to NOAA separately.

This dataset consists of video transect images (JPG files) from CRAMP surveys taken in 2004 at 6 sites, some of which had multiple depths. Digital images are important for future researchers to resolve any question about how the image data were interpreted for the quantitative database, to provide the opportunity to re-analyze the images using other methods, and to return to the same locations for future comparisons.

This dataset consists of benthic data from the Hawaii Coral Reef Assessment and Monitoring Program (CRAMP) taken 2008-2010 from 24 sites on within 5 main Hawaiian Islands (Kauai, Oahu, Molokai, Maui, and Hawaii). Most sites consist of two transects along different isobaths, shallow (~2-4m) and deep (~7-13m) lines. A total of 67 transects were completed between May 2008 - November 2010. Quantitative estimates of substrate type and species were acquired. The types and coverages were derived objectively from photographic images using PhotoGrid, a software package which analyzes random points on digital still images of coral reefs and substrate. This dataset does not include the images from the transects, which are accessioned within NOAA/NODC separately.

This dataset consists of video transect images (TIF files) from CRAMP surveys taken in 2003 at 15 sites, some of which had multiple depths. Estimates of substrate type, rugosity, species type, and percent coverage will be provided to the NOAA data system within a separate data set. The video images are important for future researchers to resolve any question about how the image data were interpreted for the quantitative database, to provide the opportunity to re-analyze the images using other methods, and to return to the same locations for future comparisons.

This dataset consists of video transect images (JPEG files) from CRAMP surveys taken in 1999 at 26 sites, some of which had multiple depths. Estimates of substrate type, rugosity, species type, and percent coverage were provided to the NOAA data system within a separate data set. The video images are important for future researchers to resolve any question about how the image data were interpreted for the quantitative database, to provide the opportunity to re-analyze the images using other methods, and to return to the same locations for future comparisons.

This dataset consists of digital still transect images (JPG files) from CRAMP surveys taken on Maui in 2006 at 8 sites, some of which had multiple depths. Surveys typically consist of shallow (~3m) and deep (~10m) lines. Digital images are important for future researchers to resolve any question about how the image data were interpreted for the quantitative database, to provide the opportunity to re-analyze the images using other methods, and to return to the same locations for future comparisons. In a separate NODC Accession, text data files are given of the substrate types and coverages as derived objectively from photographic images using PhotoGrid, a software package which analyzes random points on images of coral reefs and substrate.

Rapid Assessment Transects were conducted in 2007 in the Papahanaumokuakea Marine National Monument of the Northwest Hawaiian Islands Coral Reef Ecosystem Reserve. The surveys were led by Dr. Paul Jokiel and Mr. Erik Franklin along various depth contours at 7 unique atolls or islands. This dataset consists of digital still transect images (JPG files). Digital images are important for future researchers to resolve any questions about how the image data were interpreted for the quantitative database, to provide the opportunity to re-analyze the images using other methods, and to return to the same locations for future comparisons. In a separate NODC Accession (0000881), benthic data for substrate types and coverages are given, which were derived objectively from these photographic images using PhotoGrid, a software package which analyzes random points on images of coral reefs and substrate.
