Age vs Depth profile of core GC11, collected from the Capricorn Channel off the Eastern Australian Coast

Autre

A gravity core (GC11) was collected from a depth of 502 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). Isotopic values for 18O and 13C were obtained from Gs. ruber and correlated with the SPECMAP age-model. The results highlight 4 glacial cycles, incorporating Marine Isotope Stage (MIS) 1 through to MIS 11. Isotopically heavier 18O values at ~460cm, ~345cm, 150cm, and 30cm correspond respectively to MIS 10 (359 kyr BP), MIS 8 (260 kyr BP), MIS 6 (140 kyr BP) and the LGM (20 kyr BP). Sedimentation rates are typically low, <1 cm/kyr to ~4 cm/kyr. The higher sedimentation rates are evident at glacial / interglacial terminations, but then drop off rapidly in the interglacials.
