- Abstract
Isotopic measurements of organic carbon (δ13Corg), carbonate carbon (δ13Ccarb), and oxygen (δ18Ocarb) were made at low stratigraphic resolution on samples from International Ocean Discovery Program (IODP) Expedition 369, Hole U1515A (southeast Indian Ocean). The δ13Corg values ranged from −30.2‰ to −21.0‰, with an average of −24‰ ± 2‰, whereas δ13Ccarb values ranged from 0.5‰ to 1.4‰ with an average of 1.1‰ ± 0.3‰. Carbonate δ18Ocarb values averaged 1.1‰ ± 0.8‰ and ranged from −0.3‰ to 2.4‰. Initial plans were to use the δ13Ccarb and δ13Corg profiles to identify changes in the carbon cycle at the site and to compare local patterns to global records; however, poor core recovery and lack of solid age control limited the number of suitable samples and precluded meaningful interpretation of stratigraphic patterns.
