Notes for Bonaire 2017 (8)
  • [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] DINOv3 / CoralSCOP = the folder-level runs behind the earlier two-method map headline (staged subset, not frame-matched to the Claude photos); comparison only, never averaged.
  • [c] Claude = blind 7-call point count on the EDITED photos (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.
  • [d] 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.
  • 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.
