I am interested in the Cenozoic history of surface circulation in the Atlantic Ocean, particularly in the subtropical and tropical regions. However, most information I have found so far is related to the North Atlantic.
In particular, I would like to know if the main currents and countercurrents have changed their intensity, in response to climatic and tectonic dynamics during the last 66 million years. What are the evidences for these changes? What literature would you recomend for solving questions on this topic?
Many thanks in advance.
