    • Benthic Imagery from the Kahekili Herbivore Fisheries Management Area (HFMA) since 2021

    Metadata Updated: November 22, 2025

    Photoquadrat benthic images were collected within the Kahekili Herbivore Fisheries Management Area (HFMA) in West Maui by the Pacific Islands Fisheries Science Center (PIFSC) Ecosystem Sciences Division (ESD; formerly the Coral Reef Ecosystem Division) for quantifying benthic composition.

    This metadata record is for the source imagery of the benthic cover data produced using CoralNet which is part of a separate accession and metadata record (see 'Related Items' is below, link: https://www.fisheries.noaa.gov/inport/item/30951). The images can be linked to the benthic cover by site number in each image filename (file naming convention for each photo/image is KA[YEAR][MONTH][SURVEY#][GenericImageName]);the sites are described in the site metadata file provided. All data are accessible via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive.

    Benthic cover (%) was extracted from photoquadrats where 25 photographs were taken at 1m intervals along a 30-m long transect. The resulting imagery at each site was analyzed using a web-based annotation tool called CoralNet where the benthic composition was defined for 15 points per photoquadrat.

    Lineage The haphazard sampling design and benthic photoquadrat survey methodology has been employed by the NOAA Ecosystem Sciences Division (ESD) from 2008 to 2021. Benthic imagery is collected at haphazardly selected sites. These photos are color-corrected (if necessary) prior to analysis. The data management team also uses an optical validation script to rename photos and enforce several validation checks.
