Porites corals as recorders of mining and environmental impacts; Misima Island, Papua New Guinea

Fallon, Stewart; White, J; McCulloch, Malcolm


In 1989 open-cut gold mining commenced on Misima Island in Papua New Guinea (PNG). Open-cut mining by its nature causes a significant increase in sedimentation via the exposure of soils to the erosive forces of rain and runoff. This increased sedimentation affected the nearby fringing coral reef to varying degrees, ranging from coral mortality (smothering) to relatively minor short-term impacts.
