We present new updates to the calendar and radiocarbon (14C) chronologies for the Cariaco Basin, Venezuela. Calendar ages were generated by tuning abrupt climate shifts in Cariaco Basin sediments to those in speleothems from Hulu Cave. After the original Cariaco-Hulu calendar age model was published, Hulu Cave δ18O records have been augmented with increased temporal resolution and a greater number of U/Th dates. These updated Hulu Cave records provide increased accuracy as well as precision in the final Cariaco calendar age model. The depth scale for the Ocean Drilling Program Site 1002D sediment core, the primary source of samples for14C dating, has been corrected to account for missing sediment from a core break, eliminating age-depth anomalies that afflicted the earlier calendar age models. Individual14C dates for the Cariaco Basin remain unchanged from previous papers, although detailed comparisons of the Cariaco calibration dataset to those from Hulu Cave and Lake Suigetsu suggest that the Cariaco marine reservoir age may have shifted systematically during the past. We describe these recent changes to the Cariaco datasets and provide the data in a comprehensive format that will facilitate use by the community.

更新了 0–60 cal kyr BP 的 Cariaco Basin14C 校准数据集

我们提供日历和放射性碳的新更新（14C) 委内瑞拉卡里亚科盆地的年表。日历年龄是通过将 Cariaco 盆地沉积物的突然气候变化调整到 Hulu Cave 洞穴中的气候变化而产生的。在最初的 Cariaco-Hulu 历法年龄模型发表后，Hulu Cave δ18O 记录随着时间​​分辨率的提高和更多的 U/Th 日期而得到扩充。这些更新的 Hulu Cave 记录在最终的 Cariaco 历法年龄模型中提供了更高的准确性和精确度。海洋钻探计划站点 1002D 沉积岩芯的深度标度，该样本的主要来源14C 测年，已被纠正以解释核心断裂中丢失的沉积物，消除了影响早期日历年龄模型的年龄深度异常。个人14Cariaco 盆地的 C 日期与以前的论文保持不变，尽管对 Cariaco 校准数据集与 Hulu 洞穴和水月湖的数据进行详细比较表明，Cariaco 海洋储层年龄可能在过去发生了系统性变化。我们描述了 Cariaco 数据集的这些最新变化，并以一种便于社区使用的综合格式提供数据。
