Partial mortality, size, presence, density, thermal tolerance, vital rates, and image classifiers of ESA-listed corals Acropora globiceps and Isopora crateriformis around Tutuila, American Samoa from 2025-2026
This metadata record describes Acropora globiceps and Isopora crateriformis natural history data collected from from surveys conducted by SCUBA divers and land-based experiments from February 4th-26th, 2025, March 10th-27th, 2025, and February 5th-26th, 2026 in Tutuila, American Samoa by scientists of the Ecosystem Sciences division at the Pacific Islands Fisheries Science Center. This project was funded by the Inflation Reduction Act (NA24NMFX405C0005-T1-01).
As of July 2026, all field data for this project has been collected. Colony-level partial mortality and size data for Isopora crateriformis has gone into the publication of a paper in Coral Reefs (Turnham et al. 2026). High accuracy temperature loggers made by Sea-Bird Electronics and RBR Ltd. USA were weighted and strapped to solid substrate by SCUBA divers at 11 monitoring sites set up during the 2025 field surveys. STRs were recovered at 9 of the 11 sites during 202 surveys, with two absorbed into the National Coral Reef Monitoring Program fixed site monitoring in American Samoa. Structure from Motion imagery was taken at 11 new fixed sites set up during the project, with two of them being added to the site list for the National Coral Reef Monitoring Program (NCRMP) as part of their field surveys in American Samoa. These SfM images are also used in conjunction with benthic photoquadrat imagery taken by the NCRMP was used in the development of two object detectors for the two target species of this project. The Isopora crateriformis classifier is publicly available for download (https://huggingface.co/NMFS-OSI/yolo11m-esa-coral-icra-detector), whereas the Acropora globiceps model is still in training and will uploaded to huggingface upon its completion.
Coral thermotolerance data from acute thermal stress experiments using Coral Bleaching Automated Stress System (CBASS) include maximum photochemical efficiency (Fv/Fm) and color (measured as mean pixel intensity extracted from standardized images of coral fragments calibrated against a Coral Health Chart standard). Coral vital rates at fixed sites measured using the NCRMP vital rates methodology (Amir et al. 2023) are being analyzed. Phylogenomic data on Acropora globiceps and congeners is still being analyzed.
This metadata record will be updated as these data continue to be developed in authored material.
