Notes for Florida 2019-2025 (16)
  • [a] No survey at this site (no transect, no frames manually annotated in CoralNet).
  • [b] CoralSCOP = per-frame sum of colony-mask area fractions (zero-filled; overlapping masks double-count), averaged over frames with an ok row. Area index, not a point count: denominator differs from any point-count reference. It is also unstable frame to frame (the same subject has scored 94.1% in one photo and 23.3% in another), and the mask sum overstates cover most on the healthiest reefs.
  • [c] Not applicable: the 2025 Key Biscayne dives have no edited set.
  • [d] Claude = blind 7-call point count (20 points per photo, (HC+BL)/(20 − WATER − FISH − OBST), unknown points kept in the denominator); value = the site's headline where Claude is the headline.
  • [e] NOAA NCRMP / NOAA AOML photo-transect survey, August 2016 (Manzello et al. 2019): the site headline. n = frames of the survey, not the author's photos.
  • [f] Not run on these photos.
  • [g] CoralSCOP here = the site page's frame-matched row: run on exactly the photos behind the Claude cell (per-frame values joined by file; capped at 100% per photo; zero-filled). Comparison only.
  • [h] Comparison only at a survey site: the NOAA NCRMP / AOML 2016 photo-transect value is the headline.
  • [i] CoralSCOP (mask-sum area index) = the value the map published before the Claude arm (folder-level run, not frame-matched to the Claude photos). Comparison only, never averaged.
  • [j] THIN SAMPLE (under 30 frames at this site; marked in the headline column only): indicative only.
  • Mean/Range: Mean ± SD and Range are over the CV cells that enter the mean (CoralNet where independent, DINOv3, CoralSCOP unedited/edited, Claude). Gold standard, frames manually annotated in CoralNet, Coralscapes and same-measurement cells are shown in gray italic but never averaged.
  • * The site's headline coral cover rests on only 10–19 reef-habitat photos; this estimate is less certain.
  • † Includes unedited camera originals: the 2025 Key Biscayne dives have no edited set, and Tenneco Towers (26 February 2022) was scored on 7 edited photos and 38 unedited originals.
  • Headline (site page): the coral-cover figure the site's page, report card and map pop-up print, with its method; it is never averaged into the CV mean.
  • Methods: Claude (Anthropic); DINOv3 (Meta; paper; used here as the frozen backbone of the in-house classifier); Coralscapes v1 and v2 (EPFL-ECEO; dataset paper, code); CoralSCOP (Zheng et al., CVPR 2024); CoralNet.
  • Sites: names drop the region prefix (hover for the full name) and link to the site's CRD page, or to the regional summary page where the site has none. Date = survey date from the map pins (first–last visit); sites are listed earliest first, undated sites last.
