This short core obtained off Sumatra (BAR9403, 5.82 S, 104.0316 E) records the palaeoceanography from the Last Glacial Maximum (LGM) to the present day. The lightest 18O value (-2.99ppt) is recorded during the Holocene (~5cm depth) while the LGM (~125cm depth) is positioned at the heaviest 18O value of -0.59ppt. Once the estimated ice volume effect has been accounted for, this still leaves a substantial difference in 18O which must be accounted for through significant changes in sea-surface temperature (SST) or salinity. The 13C record ranges from a minimum at approximately 8500 yrs BP of 0.16ppt to a maximum value of 1.31ppt during MIS 3.
