National Coral Reef Monitoring Program: Benthic, urchin, and fish observation data collected for coral reef carbonate budget assessments in the Hawaiian Archipelago in 2024

Published by Pacific Islands Fisheries Science Center | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 02, 2026 at 11:25 PM | Dataset Last Updated: January 01, 2026 at 12:00 AM
This data package includes the benthic, urchin, and fish observation data collected for coral reef carbonate budget assessments by the Ecosystem Sciences Division (ESD) of NOAA's Pacific Island Fisheries Science Center (PIFSC) at fixed sites around the main and Northwestern Hawaiian Islands in 2024. Urchin survey data (genus/species, test size, and abundance) were collected from in-water belt transect surveys. Fish survey data (genus/species, count, and size) were collected using stationary point count surveys conducted at fixed sites. Benthic data (genus/species, morphology, and surface distance of corals, crustose coralline algae, macroalgae, and other benthic components) were extracted from fixed-site Structure-from-Motion imagery. The raw data in this data package can be integrated with referential databases to calculate site-level coral reef carbonate production and erosion rates. The referential database used for grazing metrics of herbivorous fishes of the Pacific is archived with NCEI with its metadata accessible under 'Related Items' of this InPort metadata record. The referential database for calcification rates developed for the Pacific is accessible along with scripts for this project at the github repository: https://github.com/hannahbarkley/reefbudgetR/tree/main
