The sediments on the sea floor are natural archives of past climate and ocean variability. I propose to unravel the information preserved in these records by determining the contents of various organic remains and mineral and chemical properties, so- called proxies. The key to my novel contributions to paleo-oceanographic research is a multi-proxy approach, using a wide range of proxies, which enables my group to differentiate between local and global climate signals, and to establish phasing (i.e. causal) relationships between different components of the climate system.

海底的沉积物是过去气候和海洋变化的自然档案。我建议通过确定各种有机残留物的含量以及矿物和化学性质，即所谓的替代物，来解开这些记录中保存的信息。我对古海洋学研究的新贡献的关键是多代理方法，使用广泛的代理，使我的团队能够区分本地和全球气候信号，并在气候系统的不同组成部分之间建立阶段（即因果关系）关系。
