CRAMP surveys have monitored Hawaiian coral reefs quasi-annually since 1999. This 2016 subset includes 20 transects across 10 sites on Maui, with digital still images analyzed via PhotoGrid software to derive substrate type and species identification data. The program is archived by NOAA's National Centers for Environmental Information.
Use Cases
- Classify substrate_type from digital still images using image recognition models.
- Analyze species_identification data to model benthic community structure across shallow and deep isobaths.
- Train models to predict reef health indicators by correlating image-derived point data with environmental factors.
- Use transect location and isobath depth data to assess spatial patterns in coral cover.
- Benchmark automated image analysis tools against manual PhotoGrid point analysis results.
Strengths
- Long-term monitoring program with data collected quasi-annually since 1999.
- Includes data from 20 transects across 10 distinct sites on Maui.
- Data collection spans two depth zones (shallow ~2-4m and deep ~7-13m) per site for comparative analysis.
Limitations
- Only every other captured image was analyzed, reducing the potential sample size for image-based models.
- Temporal coverage for this specific accession is limited to a two-month period in 2016.
- Sample size (rows) and specific column schema are unknown, complicating initial assessment.
