Small drop in sea level had big impact on southern Great Barrier Reef

A small drop in sea level 2000 years ago on the southern Greater Barrier Reef led to a dramatic slowdown in the coral reef's growth, research shows. The researchers analyzed samples from One Tree Reef in the southern Great Barrier Reef. They radiocarbon dated sediment cores from the lagoons of the coral reef to calculate sand infilling. Sea level change was calculated by dating fossil samples from micro-atolls.
