Site description

Setting

Global Reef Expedition station AU91112 on Unnamed Reef 11-091, far northern Great Barrier Reef (-11.3986, 143.9677), surveyed on 23 September 2014. The expedition's own site table classifies AU91112 as an outer barrier reef on an exposed aspect.

General benthic features

Alongside the hard coral already reported for this site, the same transects recorded 13% crustose coralline algae, 5.6% turf, 1.8% macroalgae, and 1.4% cyanobacteria. Non-living substrate came to 5.9% dead coral, 25% rubble, and 14% sand. These figures come from the expedition's own 933-site benthic master and are survey results, not photographic estimates.

Coral cover

Reference: Khaled bin Sultan Living Oceans Foundation, Global Reef Expedition (in situ transect)
Transect mean 32 ± 8.2% SE (n = 11 transects; Living Oceans Foundation per-transect benthic data); the headline above is the expedition's station value (the headline weights each depth equally).

Fish and other fauna

Paired fish transects recorded about 37 fish species per transect and about 43 kg per 100 m2 of biomass.
