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.

“It would be some advantage to live a primitive and frontier life, though in the midst of an outward civilization, if only to learn what are the gross necessaries of life and what methods have been taken to obtain them.”
