More info
Eastern Philippines (NOAA CRW virtual station)This Moalboal pin covers three February 2013 dives that Anderson's log rates highly for coral — Talisay especially, with near-continuous cover of all major coral families, plus a night dive with a blue-ringed octopus and squid. All 19 photographs are topside, so no cover estimate exists; the nearest Reef Check station, 1.28 km off, recorded 17% hard coral in its latest survey (July 2007).

Site description
Setting
The Moalboal marker sits on the Panagsama Beach shorefront on the southwest coast of Cebu, facing Negros across the Tanon Strait and stands for three dives logged with Blue Abyss over 10 and 11 February 2013.
Coral cover
- No coral-cover estimate exists for this site, and neither computer vision model has been run on it.
Stressors
Nothing bleached, diseased, recently dead, or crown-of-thorns-affected is visible, which is a limit of the imagery rather than a finding. Shorefront development is dense and built to the waterline, and moored bangkas are numerous.
Comparisons with other data
Reef Check stations within 2.5 km ran from 12% to 32% between 2005 and 2007, so the external figures describe this coast rather than these dives. These Reef Check figures come from nearby independent surveys, not from a survey of this site. No coral-cover value exists for this site.
Dive record
"Sambaguita" on 10 February ran to 19.2 m over 68 minutes with 15.2 m visibility, most of it on a wall at about 10 m, and the log records that in 3 to 4 m at the end of the dive the bottom was near-continuous coral for as far as Anderson could see, mostly branching Porites. "Talisay" on the afternoon of 11 February, 22.3 m over 60 minutes, had close to continuous coral cover for most of its length and with all major coral families represented: poritids, agaricids, acroporids, pocilloporids, fungids, and gonioporids all logged. A night shore dive on the house reef followed, 10.1 m over 65 minutes, with a juvenile blue-ringed octopus, squid, two turtles, and decorator crabs.

All 19 photographs of this site are topside (photos not shown).

Independent surveys nearby
Within 5 km, 12 independent survey stations recorded hard coral cover in 32 surveys between 2005 and 2012. Of the 4 stations surveyed in more than one year, 3 declined (by 1.0–5.0 points) and 1 increased (by 17 points) between their first and latest surveys. Two stations share the longest span (2005–2007); one, Tomonoy (Reef Check, 3.30 km away), went from 14% in 2005 (mean of 2 surveys) to 31% in 2007 (mean of 2 surveys). The most recent nearby survey is from 2012, so these values predate recent heat stress.
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.
