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

科学摘要：本提案要求支持利用热带卡里亚科盆地的沉积物构建15 - 55历基尔BP期间的详细14C校准数据集。卡里亚科盆地多变的沉积物允许年度分辨。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。该研究将从卡里亚科盆地获得一系列高分辨率放射性碳年代，并将其与GISP2冰芯记录的年代学进行校准。

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.
