Long-term Monitoring Program survey reports

Surveying the Great Barrier Reef for more than 30 years

The AIMS Long-term Monitoring Program has monitored the condition of reefs in the Great Barrier Reef World Heritage Area since 1983. It is the most comprehensive record of reef condition available for the Reef.

Surveys involve a series of four or five field trips annually which are reported on soon after their conclusion.

Ninety-three reefs of the Great Barrier Reef are monitored as part of this program. An additional 32 inshore reefs are monitored as part of the Marine Monitoring Program.
