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.

Famous quotes containing the word methods:
“Generalization, especially risky generalization, is one of the chief methods by which knowledge proceeds... Safe generalizations are usually rather boring. Delete that “usually rather.” Safe generalizations are quite boring.”
—Joseph Epstein (b. 1937)
