Description :
Fringing reefs and storm ridges, from inner shelf sites on the Great Barrier Reef between 14 and 20 5 are examined for holocene sea-level and climatic changes. 45 radiocarbon results show that sea level fell smoothly from + 1 m at 6000 yr B.P. to its present position No evidence for secondary oscillations of sea-level has been found. The average recurrence interval of major ridge-building storm is about 80 yr. Statistics of the series of storm-ridge ages do not show any identifiable changes in frequency of ridge building over the last 4000 yr and perhaps 6000 yr.
