Deep ocean circulation has a crucial impact on climate, by transporting heat, salt and nutrients between the tropics and the poles. In the past 50 million years, greenhouse gases were much higher, and deep ocean circulation may have greatly changed over time. We do not fully understand why. This project will use climate model outputs to reconstruct geochemical tracers such as Neodymium, Oxygen, and Carbon and through the deep past. We will use matrix methods to accelerate these reconstructions, enabling fast computation of results. These tracers can be used to reconstruct how the deep ocean circulation evolved through time and compare with geological data. This will help us to understand possible changes of deep ocean circulation due to future climate change.
To use Earth’s history and climate models to better understand and predict future changes.
