GBR - Coral calcification (AIMS)


Posted on 14 February 2009

The purpose of this study was to quantify patterns in skeletal density, linear extension and calcification throughout the GBR based on the AIMS Coral Core Archive of 328 colonies of massive Porites from 69 reefs. Annual data for the three growth parameters, skeletal density, annual extension, and calcification rate (the product of skeletal density and annual extension) were obtained from each colony using standard x-ray and gamma densitometry techniques. The data set contains 16,472 annual records, with corals ranging 10 – 436 years in age, most of which were collected in two periods covering 1983 – 1992 and 2002 – 2005. The oldest colony dates back to 1672.
