Colony-level annotations using Structure-from-Motion models from sites surveyed across the Main Hawaiian Islands during the 2019 bleaching event (NCEI Accession 0244392)

browse graphicPreview graphic
Coral adult colony demographic data described in this dataset are derived from the GIS analysis of benthic photomosaic imagery. The source imagery was collected using a Structure from Motion (SfM) approach during in-water surveys conducted by divers. The data were collected by the NOAA Pacific Islands Fisheries Science Center (PIFSC) Ecosystem Sciences Division (ESD; formerly the Coral Reef Ecosystem Division) and [on Hawaii Island] in partnership with State of Hawaii Department of Land and Natural Resources (DLNR), Division of Aquatic Resources (DAR) during the 2019 bleaching event in the Main Hawaiian Islands.

The SfM surveys were conducted at fixed sites ranging in depth from 18-52'. Sites were photographed using underwater cameras for later processing using one of two SfM approaches: using a spiral swim pattern (where divers take images continuously in a circular pattern covering a circle of 12m diameter), or within a defined box where divers swam back and forth to cover a 10 x 10m area. The photographs were processed using Agisoft Metashape software to generate orthomosaic images that were analyzed in ArcGIS for adult coral colony demographic metrics. Data was collected for each site within at least 10 randomly generated 0.49m2 quadrats. Additional quadrats were analyzed if necessary until the sample sizes per species of interest were met. If a species had very low density at a given site (< 10 patches recorded within the first 10 quadrats), it was dropped from further observations. However, the data for these patches remains in the raw data in order to provide presence/absence data. Therefore, data should be carefully analyzed to ensure accurate species density calculations are done. For each adult coral colony patch (>= 5cm in diameter), maximum diameter, ID (to lowest taxonomic level), morphology, bleaching extent (% of the patch with reduced pigmentation), and bleaching severity (1-3 from least to most severe) were recorded.

Supplemental Information
**Note**: This data package does NOT include the source Structure from Motion (SfM) imagery, or intermediate data products such as orthomosaic images, as mentioned in the methods section of the abstract. It solely contains annotated adult coral demographic data derived from these images.
Purpose The Hawaii Coral Bleaching Collaborative (HCBC) planned and executed a field survey response in 2019 that applied a structured, hypothesis-driven approach to document the extent of coral bleaching in the Hawaiian Archipelago, and laid the groundwork for tracking coral response and recovery through time. The purpose of the Structure from Motion (SfM) surveys throughout the Main Hawaiian Islands is to efficiently and effectively collect coral demographic data.
