PhD Project: The Impact of Northern Hemisphere Glaciation on Deep and Intermediate Ocean Circulation The late Pliocene was the most recent geological period with average global temperatures warmer than the present, and this was followed by a rapid expansion of ice sheets across the Northern Hemisphere. Understanding this process will help us to better understand the climate dynamics that might shape our future climate. Ocean circulation modulates the climate through transport of heat and carbon around the world. The circulation patterns of the deep and intermediate Pacific Ocean appears to have changed considerably during this glaciation. Using trace metals and radiogenic elements contained in the calcite tests of foraminifera, my research aims to better constrain the dynamics driving the ocean circulation during this time.
