Shaded value = in the CV mean (shade deepens with cover) Grey italic = shown for comparison but left out of the CV mean: the gold standard and manual CoralNet annotations (human reference values, not models), Coralscapes (not trusted), and any value that reuses the reference's own data n = frames behind the value — = not run or not applicable (see each region's notes) Site names and method names link out (new tab)

Notes for St. Vincent and the Grenadines 2019 (Mayreau) (14)
  • [a] No gold standard exists (no transect, no frames manually annotated in CoralNet).
  • [b] Not applicable: no CoralNet source / hand annotations exist for these photos.
  • [c] Not yet run for SVG (queued).
  • [d] DINOv3 (in-house, frozen Alor/Indonesia model) = mean hard-coral probability over 20 synthesized points per photo, NO water/fish class, so not a benthic denominator (from the map build's site cover table).
  • [e] Not yet run for SVG (queued).
  • [f] Not yet run for SVG (queued).
  • [g] Not run: EDITED region by ruling.
  • [h] Not yet run: an older SVG CoralSCOP run may be on Anderson's external drive (queued, the project data files).
  • [i] Value read from the map's CV method tables (injector output, generated 2026-09-28 22:33); the scope text there gives denominator and frame set.
  • [j] Claude = blind 7-call point count on the EDITED photos, 20 points per photo, (HC+BL)/(20 − WATER − FISH − OBST), UNK kept in; mean across photos (arm ledgers, via the map's CV method tables).
  • 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 but never averaged (*).
  • 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.
