Site description

Setting

FJNA38SN (Nayau, Lau Archipelago): surveyed 16 Jun 2013 during the Khaled bin Sultan Living Oceans Foundation Global Reef Expedition. The expedition's site table records it as a 2-m reef-flat station on Nayau's leeward northwest side; no coral cover, habitat notes, or photographs exist for it.

Stressors

No benthic transects, site notes, or sampled colonies exist for this reef-flat snorkel station, so no bleaching, disease, crown-of-thorns starfish, cyanobacteria, or recent mortality is recorded here. Island-level context, not an observation here: the expedition's notes for Nayau's fore-reef dive stations record Drupella snails on several Acropora, and Anderson's sample sheet records small pale or bleached patches (1-10% of the colony) on four of seven colonies at FJNA38.
