Shaded value = in the CV mean (shade deepens with cover)Gray italic = shown for comparison but left out of the CV mean: the gold standard (the reference value) and the manually annotated in CoralNet CoralNet benchmark annotations (reference values, not models), Coralscapes (not trusted), and any value that reuses the reference's own datan = frames behind the value— = not run or not applicable (see each region's notes)Site names and method names link out (new tab)
[a] 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.
[b] 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.
[c] Claude = blind 7-call point count on the EDITED photos where they exist (Sites 13 and 7: unedited photos, †) (20 points per photo, (HC+BL)/(20 − WATER − FISH − OBST), unknown points kept in the denominator); value = the site's headline as printed on its page.
[d] Not run on unedited photos at this site.
[e] CoralSCOP (mask-sum area index) = the value the map published before the Claude arm, from the earlier folder-level CoralSCOP run; NOT frame-matched to the Claude photos (n = that run's frames where recorded). Comparison only, never averaged.
[f] 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 photographs: edited versions of these photos do not exist.
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.
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.
