Stable isotope composition of Neogene planktonic foraminifera from ODP Leg 130 sites ...
We produced a preliminary record for shallow-dwelling planktonic foraminifer d18O at Site 807 for the late Pleistocene, early Pliocene, and early Miocene. Site 807 d18O values between 4 and 5 Ma average 0.75 per mil more than Holocene values and show an average variation of 0.5 per mil. For the earl...
