More info
East Nusa Tenggara (NOAA CRW virtual station)A seamount near Gili Lawa in northern Komodo, dived once in August 2009 and logged as one of the park's famous sites for fish abundance. No survey or photographs came off the dive, so there is no coral-cover estimate, and a planned 2019 revisit was missed through illness.
Gunung laut di dekat Gili Lawa di Komodo utara, diselami sekali pada Agustus 2009 dan dicatat sebagai salah satu lokasi terkenal di taman ini karena kelimpahan ikannya. Tidak ada survei atau foto dari penyelaman itu, sehingga tidak ada perkiraan tutupan karang, dan kunjungan ulang yang direncanakan pada 2019 terlewat karena sakit.

Site description
Setting
Crystal Rock is a seamount site in the north of Komodo National Park, near Gili Lawa.
Coral cover
- No survey or photographic data came off the 2009 dive, so there is no cover estimate and no imagery to derive one from.
Stressors
Heat stress: five-year mean annual maximum of 6.3 degree-heating weeks (2021–2025, NOAA Coral Reef Watch East Nusa Tenggara virtual station).
Comparisons with other data
Turicchia et al. (2018) surveyed this site (Crystal Rock). Within 5 km, one independent station, WWF-US / WWF-Indonesia at TNK05, 1.98 km away, read 67% in 2016.
Dive record
It was dived on 17 August 2009 — entry 10:45, maximum depth 27.1 m, 71 minutes bottom time — and the 2009 log records it as one of the park's famous sites for fish abundance. Anderson returned on 21 January 2019 but did not dive because of illness.
No underwater photographs from this site are on file.
Independent surveys nearby
Within 5 km, 1 independent survey station recorded hard coral cover in 2016. The most recent nearby survey is from 2016, so these values predate recent heat stress.
Collected by other programs using different methods, 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.
