The Long-Term Monitoring Program begins annual reef surveys

Assembled from 32 blocks · 1 evidence · 16 related

1. Story
2. The Australian Institute of Marine Science begins surveying a fixed set of Great Barrier Reef sites with a consistent method every year. Almost every subsequent quantitative claim about whether the reef is declining or recovering rests on this series, because it is long enough and consistent enough for a change to be distinguished from a change in how the reef was looked at.

31. Evidence
32. Mean hard coral cover on surveyed Great Barrier Reef sites fell from 28.0 per cent in 1985 to 13.8 per cent in 2012, with roughly forty-eight per cent of the loss attributed to tropical cyclones, forty-two per cent to crown-of-thorns starfish and ten per cent to bleaching. V55 verification basis: not consulted; the cover figures and the three attribution percentages are stated from the producing model's knowledge of this widely cited result.
