This dataset contains the age model tie points used to establish the chronology of Ocean Drilling Program (ODP) Site 108-662 (1°23.4′N, 11°44.0′W; 3,814 m water depth) in the eastern equatorial Atlantic. The dataset includes composite depth, adjusted benthic foraminiferal oxygen isotope values, and tuned ages used to correlate the record to the LR04 global benthic oxygen isotope stack. The chronology spans the late Pliocene to early Pleistocene and provides the temporal framework for the associated foraminifera-bound nitrogen isotope measurements.
