Survey reports


AIMS has monitored the condition of reefs in the Great Barrier Reef World Heritage Area since 1983. Surveys involve a series of four or five field trips annually.

Survey updates are circulated shortly after each field trip. They summarise the results of manta tow and scuba search surveys to show major changes on the reefs surveyed.  At core survey reefs, reef fishes are counted and  the cover of benthic organisms on marked transects is estimated from photographs, but these take some time to process.  The results are presented on the reef pages and in the scientific literature.

Ninety-three reefs of the GBR are monitored as part of the AIMS Long-term Monitoring Program. An additional 32 inshore reefs are monitored as part of the Marine Monitoring Program.

Annual summary reports

In 2012, AIMS reported the average coral cover on the GBR had declined by 50% over a 27-year period, based on data from the long-term monitoring program. In 2016 , a condition update was provided to reflect the 4 years of monitoring since the 2012 report. This update is now provided annually.
