Reef Check first conducted a global survey of coral reef health in 1997. The data confirmed that coral reefs were in crisis due tooverfishing,pollution and otherhumanimpacts.[4] The published results in 1999 unsettled the coral biologist community, as the extent of impacts were not realized.
"The Global Coral Reef Crisis: Trends and Solutions (1997-2001)", a five-year report on coral reefs, was released in 2002 at theWorld Summit on Sustainable Development inJohannesburg,South Africa.[5] The report used data collected by thousands of volunteers worldwide, and was the first scientific document detailing the decline in coral reef health over a five-year period.
In 2005, Reef Check launched its firsttemperate reef program in California, collecting data on California’s kelp forests with the goal to inform the emerging statewideMarine Protected Area (MPA) network.[6] Since then, Reef Check’s Kelp Forest Monitoring Program has grown to be the largest scuba-based citizen science program.
In 2016, this program expanded intoclimate change monitoring and is now providing ocean temperature data from over 75 sites.
In 2020, Reef Check began working on restoring kelp forests, with the hope of reversing some of the devastating collapse of these ecosystems along the North American West Coast. The focus of this program is on community-based restoration by engaging volunteers and providing economic benefit to the local communities that depend on the ocean environment who are the most hard-hit by the loss of kelp in many regions.
Reef Check's Dive into Science program, launched in 2019, is designed to provide scuba andscientific diving skills for groups that have been historically absent in this effort, including tribes, low-income communities of color, and foster youth.

For its coral reef monitoring protocol, Reef Check volunteer divers are trained to study a designated site annually or sometimes quarterly. Underwater surveyors focus chiefly onsessileinvertebrates (benthos), along a 100-meter (330 ft)transect line.[7][8][9]
Four spatialreplicates (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 observesubstrate,photographmacroinvertebrates and impacts, record video, and countfishes. A site-specific description is also documented.
Reef Check carries out its work through four major programs: the Coral Reef Program,[10] Kelp Forest Program,[11] Kelp Restoration Program,[12] and Dive into Science Program.[13]
