Stable oxygen and carbon isotope record of Neogloboquadrina pachyderma of ODP Leg 178 holes
Oxygen and carbon isotopic ratios were measured on left-coiling Neogloboquadrina pachyderma separated from sediments recovered from Holes 1096B (3152 m water depth) and 1101A (3280 m water depth) during Ocean Drilling Program Leg 178. The sediment samples were widely spaced, extending over the past...

Summary: | Oxygen and carbon isotopic ratios were measured on left-coiling Neogloboquadrina pachyderma separated from sediments recovered from Holes 1096B (3152 m water depth) and 1101A (3280 m water depth) during Ocean Drilling Program Leg 178. The sediment samples were widely spaced, extending over the past 2.1 m.y. The nature of the sediments from which they were separated and the measured oxygen isotopic ratios show that N. pachyderma (s) is preserved in both glacial and interglacial sediments over the entire period, pointing to the possibility of extracting a detailed isotopic record at these sites extending back to 2.1 Ma. |
