Corallivory, or coral predation, data derived from Structure-from-Motion imagery and in-situ surveys of coral reefs off of O'ahu, Hawai'i from 2021 to 2022

Description

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'. The source SfM imagery will be accessible via Google Cloud bucket (see URLs). 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. In water bite counts and estimates derived from SfM annotations will be compared with visual survey data to better understand the accuracy at which SfM annotations capture corallivory.

Surveys were conducted by the NOAA Fisheries Ecosystem Sciences Division in partnership with the University of Hawaii at Manoa. *Note - While the in situ data includes sea star and Drupella corallivory data, the SfM derived estimates dataset does not include these types of predation because they require a different annotation methodology in ArcGIS Pro. Moreover, because they were encountered so infrequently while conducting in situ surveys, the decision was made not to annotate these predation types. https://accession.nodc.noaa.gov/0286084
