A small wreck beside a coral pinnacle, its hull now crusted in coralline algae and cauliflower corals with glassy sweepers packing the passageways; nearby derelict coral-farming tables show mostly dead transplants with a few survivors. Computer vision cover estimate is 18-21%, averaging 19.6%.

A small ship sits upright on the sand beside a coral pinnacle, and after years underwater the two have nearly merged: hull plates crusted in pink coralline algae, railings sprouting cauliflower corals, massive mound corals squatting on the deck, and dark passageways packed with shimmering clouds of glassy sweepers (e.g., Image 2, Image 10, Image 12, Image 14).
Just beyond, the pinnacle's shallow crown blazes with healthy table and cauliflower corals (e.g., Image 4, Image 20).
Coral cover: 20% — photo-derived, and the two methods broadly agree (18% vs 21%). This site's figure is the mean of two independent computer vision passes over Anderson's own frames: a DINOv3 calibrated point classifier reads 18.2% and a CoralSCOP computer vision reads 21%, a spread of 2.8 percentage points. The map publishes the mean so sites can be sorted against one another, but the honest statement of what is known here is the 18–21% range: the two products have different denominators and should not be treated as one measurement.
There's a bittersweet detail here too: derelict coral-farming tables lie nearby, most of their transplanted fragments long dead, though a few stubborn survivors still hang on (e.g., Image 16, Image 22).
No crown-of-thorns starfish (COTS) or other corallivores evident.
A pair of Moorish idols patrols the wreck, orange anthias swarm the framework, and a huge sea anemone on the structure shelters anemonefish with a single white bar — the Maldives' own species (e.g., Image 5, Image 23).

Dr. Coral (CRD)Year-average (no detectable trend)Within 5 km, 4 independent survey stations recorded hard coral cover in 5 records between 2015 and 2022. Of the 1 station surveyed in more than one year, 1 changed by less than 5 percentage points between their first and latest surveys. The longest record, transect 37035 (XL Catlin Seaview Survey, 3.08 km away), went from 7.1% in 2015 to 5.5% in 2017. One survey since 2021 recorded 19%. This site's own estimate (20%) is indistinguishable from the recent value (19%): the 0.2-point gap is inside the ±7 percentage-point noise between methods; the methods differ, so the comparison is context, not a like-for-like test.
Collected by other programs using different methods (Reef Check uses point-intercept transects; the XL Catlin Seaview Survey uses photo-transects with automated image annotation), so these are context for the figures above, not a like-for-like comparison. Where a station was surveyed more than once the range is shown. Station names are not dive-site names. Values marked best patch exceed 70%: surveyors usually chose the richest area, so they are not site means.
