Under this award the PIs will examine the constancy of d13C in the Norwegian Greenland Sea overflow waters that make up North Atlantic Deep Water. The proponents will focus on intervals that represent typical and extreme G-I stages, in order to develop a better understanding of the processes that gave rise to the anomalous d13C profiles of the last 400 kyr. In this way the study hopes to seek to answer fundamental questions about the long-term circulation history of the North Atlantic and its susceptibility to change. The research should perform a critical step in the evaluation of climate models used to predict future circulation changes is judging the ability of those models to hindcast past ocean circulation changes. Paleoceanographers are responsible for providing accurate depictions of such changes. The award will involve public education outreach and undergraduates in our research.

根据该奖项，PI 将检查构成北大西洋深水的挪威格陵兰海溢流水域中 d13C 的稳定性。 支持者将重点关注代表典型和极端 G-I 阶段的区间，以便更好地理解导致最后 400 kyr 异常 d13C 剖面的过程。通过这种方式，该研究希望寻求回答有关北大西洋长期环流历史及其变化敏感性的基本问题。 这项研究应该在评估用于预测未来环流变化的气候模型时迈出关键一步，即判断这些模型预测过去海洋环流变化的能力。古海洋学家有责任提供此类变化的准确描述。 该奖项将涉及公共教育推广和本科生参与我们的研究。
