Monitoring Methods
Reef Check volunteer divers are trained to study a designated site annually or sometimes quarterly. Underwater surveyors focus chiefly on sessile invertebrates (benthos), along a 100-meter (330 ft) transect line.
Four spatial replicates (spanning 20 m (66 ft)) are studied with three 5 m (16 ft) gaps between. The survey is sub-divided to allow paired divers to separately observe substrate, photograph macroinvertebrates and impacts, record video, and count fishes. A site-specific description is also documented.
