Description

A sequence of shallow reef cores from Heron Reef, Great Barrier Reef, provides new insights into Holocene reef growth models. Isochron analysis of a leeward core transect suggests that the north-western end of Heron Reef reached current sea-level by ca 6·5 kyr bp and then prograded leeward at a rate of ca 19·6 m/kyr between 5·1 kyr and 4·1 kyr bp (pre-1950) to the present reef margin. A single short core on the opposing margin of the reef is consistent with greater and more recent progradation...[Show more]
