Outlier score: 5.00/5 (Cicia, n = 8 corals with an outlier score). The share of those corals whose molecular stress profile was an outlier, rescaled to 0-5 (5 = no outliers); an island-level measure (Mayfield et al. 2017), not a Coral Health Index.

Site summary
Read this summary in:

A flat-topped coral mound off Cicia whose entire upper surface is paved with table Acropora stacked like shingles, in cream, sea-green, olive, mauve, and salmon, under clouds of anthias and fusiliers. Coral cover is about 50%, with no bleaching, disease, or crown-of-thorns seen. Surveyed on the Living Oceans Foundation's Global Reef Expedition.

Site description

General benthic features

Of the 28 frames in this station's folder, eighteen are reef-scale, and every one of them shows the same thing: a broad, flat-topped carbonate mound whose entire upper surface is paved with tabulate Acropora. Image 9 is the clearest — the whole dome silhouetted against blue with plates stacked shingle-fashion from the base to the summit and no visible break in the framework.

Image 15 and Image 26 show the same structure from closer in, tables layered over lower plating and corymbose colonies.

Image 2 shows the texture clearly: a shoulder of reef at Anderson's noted 10 m carrying tables in an unusual spread of colors — cream, pale sea-green, olive, mauve, and salmon — with pink corymbose Acropora, a bright orange encrusting sponge, staghorn thickets at the edges, and a wall of schooling fish behind.

Image 27, Image 8, Image 3, Image 1, Image 10, Image 21, Image 24, Image 25, Image 14, Image 16, Image 23, and Image 11 repeat that assemblage across the site with divers' exhaust bubbles and clouds of anthias, fusiliers, and blue-green damselfish over it; Image 28 and Image 22 are hazier green-cast versions of the same terrain.

Growth forms are overwhelmingly acroporid — tabulate first, then staghorn and corymbose — with encrusting red algae and pink coralline crust binding the framework between plates and only small patches of turfed dead surface showing through.

Coral cover

Stressors

No bleached tissue, disease lesion, or crown-of-thorns feeding scar resolves anywhere in the reef-scale set. One frame shows an anchor chain lying across the reef, which Anderson noted as a bad place to anchor (e.g., Image 24). The Living Oceans Foundation transects here recorded 5.3% cyanobacteria and no recently dead coral.

Comparisons with other data

FJCC45 (Cicia, Lau Archipelago) was surveyed 18 Jun 2013 during the Khaled bin Sultan Living Oceans Foundation Global Reef Expedition. The benthic community is highly diverse and coral-dominated often with a substantial macroalgae component. Environment and disturbance regime govern benthic community structure. Scleractinian diversity is very high and often dominated by acroporids, pocilloporids, poritids, and faviids. The edge of the shallow slope is often dominated by large Pocillopora eydouxi colonies, thick-branched and elkhorn-like Isopora sp, and unusually large Favia stelligera and/or Pavona maldivensis stands. The expedition's 2013 field report records 212 crown-of-thorns starfish removed from one shallow outbreak reef elsewhere on Cicia, not tied to this station.

Other notes

The remaining ten frames document tagged-colony work rather than the reef: individual knobby Pocillopora-form and corymbose acroporid colonies each carrying a plastic livestock-style tag on a colored cable-tie tether, with a gloved hand holding a white cylindrical instrument head against the colony surface in most of them (e.g., Image 4, Image 5, Image 6, Image 7, Image 12, Image 13, Image 17, Image 19, Image 20), and one frame of a second diver working a large housed camera over a tagged colony (e.g., Image 18).

Anderson's notes record that these colonies were not collected — they were tagged and measured in place, not sampled.

CV model comparison

The LOF Global Reef Expedition in-water transect is THE coral-cover value for this site.
More infoThe photo row below is a methods comparison only: it is never averaged with the transect and never used as the headline. It compares site means only: the photos come from the same survey dive as the transect but not from the same points.
MethodHard coral cover (%)Photos (n) ± SE
Transect mean (all transects)49.8
CoralSCOP edited41.4*n = 18 · SE 3.6
Claude (edited photos)41.0*n = 18 · SE 4.4

The two computer-vision methods agree within 0.4 pp (41.0–41.4%) and read 8.4–8.8 pp below the in-water transect (49.8%); the headline is the in-water transect because a diver transect is independent of the photographs.

*Based on only 18 reef-habitat photos; this estimate is less certain.
