Homogenised 5-yearly growth intervals using a stainless steel drill tip on a moveable stage. Powders for trace element analysis were rinsed and then treated with concentrated hydrogen peroxide for 15 min and subsequently rinsed and oven dried. Isotopic powders were not pre-treated with hydrogen peroxide. Isotopes calibrated against an internal lab standard, NBS 18 & NBS 19 and calculated relative to Pee Dee Belemnite. d18O = 0.1 permil.

notes: 'Latitude and longitude matched to other records with the same core ID. GPS coordinates plot the core on Magnetic Island. Thought to be the same coral head later sampled by AIMS as GFB31. Higher resolution GPS coordinates for latitude and longitude of GFB31 coral head are -19.155083, 146.866167.' has been replaced by 'Thought to be the same coral head later sampled by AIMS as GFB31.'
