The dataset was discussed in a chapter of my PhD thesis. The astronomically adjusted age model of ODP Site 752 has been published. However, the age-depth model of ODP Site 754 still needs to be updated. The fine-tuning step of the Site 754 age-depth model can be done by site-to-site correlation because carbon and oxygen stable isotope values between two sites are comparable. I first applied the bio-datum to Site 754 to convert the stable isotope records from the depth domain to the time domain. In the next step, I fine-tuned the biostratigraphic age-depth model by correlating distinct stable isotope events between sites 752 and 754.
