Abstract:

New bulk sediment stable carbon and oxygen isotope data from ocean sediment cores drilled on Shatsky Rise that span the Late Cretaceous (DSDP Site 305; ODP Sites 1207, 1208, 1210, 1212). Stable isotope analyses were performed at MARUM - Center for Marine Environmental Sciences - University of Bremen ThermoFisher Scientific 253plus gas isotope ratio mass spectrometer with Kiel IV automated carbonate preparation device from July 2025 through February 2026. An internal house standard (Solnhofen limestone) was used to calculate the error over the measurement period. The bulk sediment stable isotope data was integrated with X-ray fluourescnece scanning at the same sites to build a Shatsky Rise composite astronomically-tuned reference. Therefore, the composite depths and time are a reflection of high-resolution correlation and astronomical age model development.
