My project involves reconstructing oceanographic circulation changes and the resultant climatic interactions. I focus on combining the use of geochemical tracers of ocean circulation with Earth System Models to understand and constrain long-term changes in ocean circulation and subsequent climate dynamics, particularly focussed on the Atlantic Meridional Overturning Circulation (AMOC). In my project I am simulating geochemical tracers of ocean circulation into complex numerical coupled GCM models (HadCM3/FAMOUS). I aim to mathematically represent and parameterise the sources, sinks and internal cycling of isotopic tracers in the ocean, developing a novel isotope scheme. From this I will use my model as tool to study long-term stability of AMOC through running climate simulations. I will also simulate shorter, abrupt climatic transitions such as Heinrich Event 1 and the resultant response of the climate and carbon cycle to such forcings.
