Radiocarbon Calibration And Climate Change During Marine Isotope Stages 2 and 3

科学摘要：这项提议要求支持利用热带Cariaco盆地的沉积物为15-55个日历Kyr BP期间建立一个详细的14C校准数据集。卡里亚科盆地的各种沉积物允许年度分辨率。Caricaco盆地的古气候记录与GISP2冰芯的详细记录显示出相同的变化。这项研究将从Cariaco盆地获得一系列高分辨率的放射性碳测年数据，并将它们校准为GISP2冰芯记录的年代学。

Science Summary: This proposal requests support to construct a detailed 14C calibration data set for the period from 15 - 55 calendar Kyr BP using sediments of the tropical Cariaco Basin. The varved sediments of the Cariaco Basin allow annual resolution. Paleoclimate records from the Caricaco Basin show identical variation to detailed records from the GISP2 ice core. The study will obtain a series of high-resolution radiocarbon dates from Cariaco Basin and calibrate them to the chronology of the GISP2 ice core record.
