    • Benthic, urchin, and fish observation data collected utilizing multiple methodologies for coral reef carbonate budget assessments in 2021 in O'ahu, in the Mariana Archipelago in 2022, and in American Samoa in 2023

    Metadata Updated: May 24, 2025

    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 O'ahu in 2021, across the Marianas Archipelago in 2022, and at two fixed sites in American Samoa in 2023. These data were collected as part of a three-year methods development and pilot project funded by the NOAA Coral Reef Conservation Program (CRCP) in order to establish a standardized carbonate budget methodology for the National Coral Reef Monitoring Program (NCRMP) in the U.S. Pacific Islands. Observational data were collected at the same sites using established Indo-Pacific ReefBudget methodology (Perry et al. 2018), as well as experimental methodologies that leverage existing NCRMP data streams (see lineage section below for additional details on data collection methodologies). Benthic survey data (genus/species, morphology, and surface distance of corals, crustose coralline algae, macroalgae, and other benthic components) and urchin survey data (genus/species, test size, and abundance of bioeroding urchins) were collected using Indo-Pacific Reef Budget-style transects, "chords" transects located within the 12-m diameter circular footprint covered by NCRMP Structure-from-Motion imagery, and virtual transects in fixed site Structure-from-Motion models. Fish survey data (genus/species, count, and size) were collected using Indo-Pacific ReefBudget belt transects, stationary point count surveys conducted at fixed sites, and averaging stationary point count survey data using stratified random survey design around a set distance of the fixed sites.

    The raw data in this data package (urchin, benthic cover, parrotfish belt, fish SPC) was utilized with referential databases to calculate coral reef carbonate project estimates for Pacific regions as part to the CRCP Project #31334, titled 'Developing a carbonate budget assessment methodology for the U.S. Pacific Islands'. The referential database used for grazing metrics of herbivorous fishes of the Pacific is already 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
