Corallivory, or coral predation, data derived from both Structure-from-Motion imagery as well as visual in-situ surveys of coral reefs in O'ahu, Hawai'i from 2021 to 2022 (NCEI Accession 0286084)

Metadata Updated: September 2, 2025

The data described here are raw corallivory, or coral predation, data from in situ visual surveys as well as derived corallivory data from Structure-from-Motion (SfM) imagery collected during diver transect surveys between 2021 and 2022. These surveys were conducted by a graduate student researcher from the University of Hawaii at Manoa, and funded by NOAA's Coral Reef Conservation Program (CRCP), with support from scientists of the Ecosystem Sciences Division (ESD) at the Pacific Islands Fisheries Science Center (PIFSC) of NOAA. This data was funded by CRCP Project number 31349 titled: 'Determining whether herbivore-focused management strategies enhance critical ecosystem functions provided by fishes'. 39 sites off of O'ahu, Hawai'i were established for this project. At each site, a 3x20m haphazardly placed transect was surveyed and imaged using underwater cameras. Along each transect, seven 1x1m quadrats spaced 3m apart were first surveyed for corallivory bite marks. After the survey was conducted, the same 3x20m transect was imaged using an underwater camera. Photographs were processed using Agisoft Metashape software to generate 2D orthomosaics. These orthomosaics were uploaded to ArcGIS Pro to be annotated for corallivory estimates. Source imagery will be accessible via Google Cloud Bucket. This data package only includes the corallivory estimates from visual in situ surveys and derived from structure-from-motion imagery. Refer to InPort metadata record for updated link to Google Cloud Bucket to access source imagery.
