Reconstructed paleo-oxygen concentration, stable isotope measurements and Gaussian interpolated Δδ13C obtained from the IODP Site 339-U1385 for the past 1.5 Ma, including trace element analyses and Uvigerina spp. abundance over MIS 27-21
The dataset compiles reconstructed changes in deep-water oxygen concentration for the past 1.5 Ma using stable carbon isotope measurements of benthic foraminifer: the epibenthic Cibicidoidies wuellerstorfi and the infaunal Globobulimina affinis, obtained from the International Ocean Discovery Progra...
