Hawaiian islands of Oahu and Kauai contain benthic data and digital still images from 7 transects across 4 sites, collected by the Hawaii Coral Reef Assessment and Monitoring Program (CRAMP). The dataset includes substrate type and species identification derived from image analysis. NOAA/NCEI archives these records from surveys conducted between January and August 2016.
Use Cases
- Classify substrate type (e.g., coral, algae, sand) from digital still images using image recognition models.
- Analyze species identification data to model coral community composition across shallow (~2-4m) and deep (~7-13m) isobaths.
- Use transect line and site location data to assess spatial patterns in benthic cover across 4 sites in Hawaii.
- Correlate benthic data from 2016 with other temporal surveys in the CRAMP archive for change detection analysis.
Strengths
- Includes quantitative benthic data derived from image analysis via the PhotoGrid software.
- Surveys cover two distinct depth zones (shallow and deep) at most of the 4 sites.
- Part of a long-term monitoring program (CRAMP) with surveys conducted quasi-annually since 1999.
Limitations
- Limited to 7 transects and 4 sites, offering a small spatial sample of Hawaiian reefs.
- Data is from a single year (2016), providing only a snapshot without immediate temporal context.
- Specific row counts, image counts, and column details for the derived data are unknown.
