Supplemental Information
ABSTRACT SUPPLIED BY ORIGINATOR: The record of oxygen isotopic variations in foraminifer shells from deep-sea cores preserves a continuous record of ice volume and sea level oscillations. To extract the ice volume record, however, it is necessary to remove the temperature and local hydrological influence on delta18O. We employ the strategy of estimating calcification temperatures from Mg/Ca and removing this signal from an observed delta18O record of planktonic foraminifera from a core on the Cocos Ridge, eastern equatorial Pacific. The residual, delta18Owater, reveals a pattern of changes that appears to be consistent with known ice volume and sea level variations. Over the last four glacial terminations, delta18Owater decreases by 1.2+/-0.1%%. The magnitude of high stands appears to be consistent with modern sea level during MIS 5.5 (5e), 7.1 and 7.5 but somewhat lower during MIS 9.1. The magnitude of low stands is similar (~-120m) for MIS 2.2 (LGM), 6.2, 8.2 and 10.2. The Cocos Ridge record also shows a period of intermediate sea level (~-30m) during MIS 6.5. At present it is not possible to validate these estimates for those periods of time in which coral reef based estimates of sea level are unavailable.
Purpose Records of past climate and ocean circulation derived from marine sediments. Parameter keywords describe what was measured in this dataset. Additional summary information can be found in the abstracts of papers listed in the dataset citations.
