The stable isotope composition of surface sediment at seven other locations across the EEP are also listed.\r\n\r\nThese data represent the first set of bulk carbonate content and stable isotope records spanning the last 7 million years (Myr) at a resolution of >20 thousand years (kyr) from a site located off the equator in the northwestern sector of the EEP. The data bring new information on the evolution of oceanographic conditions in the northwestern sector of the EEP.\r\n\r\nThe results extend the understanding of the evolution and geometry of the late Miocene\u2060\u200a\u2013\u200a\u2060early Pliocene biogenic bloom in a wider of the EEP. Higher bulk carbonate \u03b4\u00b9\u2078O between ca 5\u2060\u200a\u2013\u200a\u20607 Myr suggests cooler sea surface tempertures (SST) at Site U1335 compared to other off-equator sites further east.","url":"http:\/\/bolin.su.se\/data\/reghellin-2022-sediment-1","keywords":["Marine","Sediment cores","Eastern equatorial Pacific","Biogenic Bloom","Late Miocene","Bulk sediment","Stable isotopes","Earth science > Oceans > Ocean chemistry > Marine geochemistry"],"creator":{"@type":"Person","name":"Daniele Reghellin, Helen K.
