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.

科学总结：该提案要求支持构建一个详细的14 C校准数据集，从15 - 55日历Kyr BP使用热带Cariaco盆地的沉积物。 Cariaco盆地的纹状沉积物允许年度分辨率。 Caricaco盆地的古气候记录显示出与GISP 2冰芯详细记录相同的变化。 该研究将从Cariaco盆地获得一系列高分辨率放射性碳日期，并将其校准到GISP 2冰芯记录的年代学。
