This report has been prepared on behalf of the Environment Service, Cook Islands as part of an ongoing monitoring programme of reef health of the fringing reef of Rarotonga. The initial work was carried out in 2000 and this is the first subsequent sampling and report since that baseline study.
Rarotonga remains an island relative void of polluting industries. The water quality outside the reef is not influenced by activities on the island to any great extent. Factors influencing reef health on the outer reef slope tend to remain natural, or at least environmental on a regional scale, as is the case of warm sea surface temperatures.
