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

Description

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.

0 Photoquadrat benthic images collected at Kahekili Herbivore Fisheries Management Area (KHFMA), Maui by the NOAA Ecosystem Sciences Division (ESD). Images are all in a single folder and organized by name only KA-[ROUND]-[ARBITRARY_SITE_NAME]_[GENERIC_IMAGE_NAME], e.g. KA2111_084_IMG_01.JPG. https://accession.nodc.noaa.gov/0255324
0 This metadata file is a list of the sites analyzed, by which the images are named (the imagery naming convention: KA-[ROUND]-[ARBITRARY_SITE_NAME]_[GENERIC_IMAGE_NAME]). This links the source imagery to the benthic cover dataset. For example: Image name: KA2111_A01_IMG_01 has site name is 'A01'; one can find this site information in the site metadata file as well as with site name in benthic cover data produced with CoralNet, whose metadata record and accession are available under 'Related Items'. https://accession.nodc.noaa.gov/0255324
0 Site metadata for benthic imagery. Latitude & longitude are excluded due to being a management area. https://accession.nodc.noaa.gov/0307662
0 Imagery collected during March and October 2024 during Kahekili surveys. Data extracted is described and archived separately - see 'Related Items'. https://accession.nodc.noaa.gov/0307662
