Outlier score: 4.17/5 (Fulaga, n = 6 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 Fulaga fore-reef station, dived to 22.6 m, with 37% coral cover against more algae, on spur-and-groove terrain with plating corals on gentler slopes. Anderson's sheet records huge, dangerous swells, 30 m visibility, rare Pocillopora damicornis, and one sampled colony (F53, 12.5 m) that was healthy with some white branch tips. Surveyed on the Living Oceans Foundation's Global Reef Expedition.

Site description

Setting

FJFU27 is a deep Fulaga fore-reef station in southern Lau, surveyed on 12 June 2013 during the Khaled bin Sultan Living Oceans Foundation's Global Reef Expedition. The expedition's site notes for the Fulaga fore reef describe a gentle slope with scattered mounds and spurs of coral framework running perpendicular to the reef crest, and a ridge of coral build-up, perforated by shore-perpendicular channels, running parallel to it.

General benthic features

The expedition's own site notes for these fore-reef stations describe spur-and-groove structure with plating and foliaceous coral stands on gentler slopes giving way to encrusting growth where the slope approaches vertical; that is the survey team's habitat characterization rather than anything read off imagery for this site.

Coral cover

Stressors

Possible bleaching: on Anderson's sampling sheet, the one colony sampled here (F53, 12.5 m) is recorded as 10% bleached, with "some white tips". The Living Oceans Foundation transects here recorded 3.6% cyanobacteria and no recently dead coral; they carry no bleaching, disease, or crown-of-thorns field. Recent thermal exposure at the Fiji virtual station has averaged an annual maximum of 8.9 degree-heating-weeks over 2021-2025 (NOAA Coral Reef Watch), above the 8 DHW level at which severe bleaching and mortality are expected.

Dive record

Bottom time was 64 minutes. Anderson's sampling sheet records huge, dangerous swells and 30 m visibility on this dive, with Pocillopora damicornis rare at the station; the one colony sampled (F53, 12.5 m) was recorded as healthy but 10% bleached, with average pigmentation, some white tips, and stubbier branches.

No underwater photographs from this station are on file.
