Quantifying the isotopic composition of oxygen and carbon through time in the core MD002361, located on the shelf edge offshore Western Australia

The calcareous tests of Globigerinoides ruber are analysed to quantify the isotopic composition of oxygen and carbon through time at core site MD002361 (113o28.63'E, 22o04.92'S). The heaviest 18O value was recorded during MIS 12 (at a depth of 1265cm) with a value of -0.04ppt, while the lightest 18O value of -2.49ppt was registered at 1200cm depth, during MIS 11. Once the estimated ice volume effect has been accounted for, this still leaves a substantial difference 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 126k yrs BP of -0.05ppt during MIS 5, to a maximum value of 2.11ppt during MIS 10.
