Part of the regional summary: Indonesia - Komodo

A genuinely dense but visibly disturbed Acropora reef in Komodo: healthy tables and colorful thickets of branching coral stand beside and on top of beds of bone-white broken Acropora rubble. Anderson did not carry the slate on this dive and logged it from memory; the photographs show many small reef fish.
Terumbu Acropora di Komodo yang benar-benar padat tetapi tampak terganggu: meja yang sehat dan rumpun karang bercabang yang berwarna-warni berdiri di samping dan di atas hamparan pecahan Acropora putih tulang. Anderson tidak membawa papan tulis selam (slate) pada penyelaman ini dan mencatatnya dari ingatan; foto-foto menunjukkan banyak ikan karang kecil.

6 of the 46 photographs on this page are shown beside the text that discusses them under "Site description" below.
Anderson's photographs show a genuinely dense but visibly disturbed acroporid reef; the log calls it a spectacular site for hard coral, with large areas at 5-9 m of 80-90% coral cover, including low-lying acroporids and finger poritids. One frame is a single large Acropora table, roughly a meter across, dark brown with a pale living rim, sitting directly on a bed of bone-white broken Acropora branches — the table is healthy, the ground it stands on is dead skeleton (e.g., Image 2).
A wide slope frame repeats that pattern at scale: a pavement of white branch rubble and old consolidated skeleton with scattered live brown foliose colonies, a tan plating colony, and low green algal turf, dropping into blue water with small planktivores above it (e.g., Image 3).
A substrate close-up in the same vein is mostly white Acropora fragments, dark red foliose macroalgae, pink and lavender crustose coralline algae, a yellow-polyped plating coral, and a small lavender soft coral (e.g., Image 1).
Against that, other frames show the reef Anderson described: a vivid salmon-red branching Acropora with white-tipped branchlets, framed by green digitate Acropora, mustard finger coral, a purple encrusting colony, and gray-brown corymbose colonies at near-continuous cover; and a mid-range garden of Acropora thickets, feathery soft corals, a broad green encrusting sheet, and orange cup coral (e.g., Image 4, Image 5).
The photo review resolved no bleaching, disease lesions, or predation scars, and nothing man-made appears; however, a computer-vision point count called 0.7% of coral points bleached (3 of 83 photos). On one green-brown knobby colony, more than a dozen knob tops are bare and white, with sharp edges against the living tissue around them: recently dead, cause not stated (e.g., Image 35).
Read the rubble as physical breakage on a current-swept slope, not as a diagnosed mortality event; these frames cannot date it.
Reef fish in frame are small — damselfish and anthias. Anderson's log records two or three green turtles, a Napoleon wrasse, a manta ray toward the end of the dive, scorpionfish, and nudibranchs.
Turicchia et al. (2018) surveyed this site (E Tatawa Kecil). Within 5 km, seven independent stations (Reef Check and WWF-US / WWF-Indonesia) recorded station-year means of 8.8–59% hard coral cover between 2016 and 2020; the nearest, Reef Check at Siaba Besar (Sector 1), 1.82 km away, read a mean of 51% in 2020.
Anderson dived this site once, on 27 January 2019 (07:34, 60 min, max 22.3 m, average depth 7.9 m, 26.7°C dive-computer average). Anderson did not carry the slate on this dive and logged it from memory; the gallery is a selection of the photographs from the dive.
| Method | Hard coral cover (%) | Photos (n) ± SE |
|---|---|---|
| In-house DINOv3 | 28.8 | n = 83 · SE 1.2 |
| CoralSCOP edited | 37.9 | n = 83 · SE 2.0 |
| Claude (edited photos) | 32.1 | n = 83 · SE 2.5 |
The two computer-vision methods differ by 9.1 pp (28.8–37.9%) and read within 5.8 pp of Claude's blind point count (32.1%); the headline is Claude's blind point count because no transect or manual count exists here.

Coral Reef DiagnosticsYear-average (illustrative only, programs differ)Within 5 km, 7 independent survey stations recorded hard coral cover in 11 surveys between 2016 and 2020. The most recent nearby survey is from 2020, so these values predate recent heat stress. This site's own estimate (32%) sits 15 points below the range of these station-year means up to 2 km away (47–51%); 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), so these are context for the figures above, not a like-for-like comparison. Where a station was surveyed more than once, the cell shows either the range of its values or, as a single value, the mean of surveys made in one year. Station names are not dive-site names.
