tropical Pacific are particularly suitable for passive remote sensing studies given the
clarity of the water column. The study site is located northwest of Moorea, within
Tiahura marine protected area (MPA). The reef health of this area benefits from a
monitoring since 1987. Covering 0.4227 km
2 , the site includes the barrier reef, reef
crest, the outer reef and a pass. Ranging from 0–23 m, the water depth distribution
shows a clear distinction between the shallow lagoon and the outer reef-pass system
(Fig. 16.4).
