Outlier score: 4.50/5 (Moala, n = 10 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

An exposed fore-reef slope on Moala's east side, where large Porites and Diploastrea colonies line the slope and small Platygyra, Lobophyllia, and Echinopora colonies are common, at 23% coral cover. Coralline algae is abundant, and cyanobacteria covered a notable 13% of the transects. Surveyed on the Living Oceans Foundation's Global Reef Expedition.

Site description

Setting

The expedition's site notes for Moala place FJML15, with FJML16, FJML22, and FJML23, on the fore-reef slope of the island's east side.

General benthic features

The same notes record large colonies of Porites and Diploastrea on the sides of the slope. Coming up the slope from 32 m, coral cover was not very high, but crustose coralline algae was common. Small colonies of Platygyra, Lobophyllia, and Echinopora were common.

Coral cover

Stressors

Cyanobacteria covered 13% of the transects. The Living Oceans Foundation transects here recorded no recently dead coral.

Comparisons with other data

The expedition's own site table classifies FJML15 as a barrier reef on an exposed aspect, surveyed on the fore reef, outside the lagoon. Alongside the hard coral already reported for this site, the same transects recorded 34% crustose coralline algae, 17% turf, 0.2% macroalgae, and 13% cyanobacteria. Non-living substrate came to 75% pavement, 0.2% dead coral, and 2.6% rubble. Paired fish transects recorded about 43 fish species per transect and about 19 kg per 100 m2 of biomass. The benthic figures are means of all of this station's own transects in the expedition's per-transect benthic records, and the fish figures come from its paired fish transects; all are survey results, not photographic estimates.
