The ocean circulation of the North Atlantic is variable and pivotal in controlling regional and global climate. This variability occurs both naturally, and it is anticipated, in response to anthropogenic activity. Internal and forced natural variability in this system has so far largely been characterised in terrestrial archives and models rather than in the real ocean. It is critical that we understand the magnitude, timescale, drivers and impacts of this variability if we are to correctly attribute observed trends in the North Atlantic circulation, and develop robust early warning systems of, and plan adaptation to, future change. In CLAM we aim to utilise a network of robustly calibrated and verified absolutely dated sclerochronological proxy archives from NW Scotland, N. Iceland and the Gulf of Maine, together with high-resolution climate models, to investigate the mechanisms and forcings driving variability in the circulation patterns of the North Atlantic over the last millennium. This proposal is a resubmission (NE/M002160/1, Jan 2014, graded 8) in which we address minor concerns highlighted by the reviewers, notably we: (i) eliminate fieldwork risks - having completed all necessary sample collection using independent funding; (ii) further-demonstrate the powerful nature of the methodologies and potential findings though additional preliminary model-proxy analyses; (iii) greater societal impact via the development of a deeper collaboration with the Met Office Hadley Centre, and (iv) deliver improved value for money, through associated cost savings.

北大西洋的海洋循环是可变的，在控制区域和全球气候方面是关键的。这种变异既自然发生，也可以预期，这是对人为活性的响应。到目前为止，该系统的内部和强迫自然变异性在很大程度上是在陆地档案和模型中的特征，而不是在真正的海洋中。如果我们要正确地归因北大西洋循环中观察到的趋势，并开发出强大的预警系统，并计划适应未来变化，那么我们必须了解这种变异性的大小，时间表，驱动因素和影响。在CLAM中，我们旨在利用来自西北苏格兰，冰岛N.冰岛和缅因州的坚固校准和经过验证的绝对日期的硬化性代理档案，以及高分辨率的气候模型，以研究北部大西洋循环模式的机制和强制性的机制和强迫，以研究北部大西洋循环模式的变化。该提案是重新提交（NE/M002160/1，2014年1月，分级8），在该提案中，我们解决了审稿人强调的小问题，尤其是我们：（i）消除现场工作风险 - 使用独立资金完成了所有必要的样本收集； （ii）进一步证明了方法论的强大性质和潜在发现，并通过其他初步模型分析； （iii）通过与大都会办公室中心进行更深入的合作，（iv）通过节省相关的成本来提高价值，通过更深入的合作，具有更大的社会影响。
