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

Published by Pacific Islands Fisheries Science Center | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 02, 2026 at 11:24 PM | Dataset Last Updated: January 01, 2026 at 12:00 AM
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 25-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.
