Postdoctoral Research Associate in Paleoclimate data analysis and modelling Cardiff School of Earth and Ocean Sciences Applications are invited for a 3 year Postdoctoral position within the Paleoclimate and Climate Systems research group of the School of Earth and Ocean Sciences at Cardiff University, UK and in association with the Alfred Wegener Institute, Germany ‘Assessing the role of millennial-scale variability in glacial-interglacial climate change’ During the Pleistocene epoch (or at least the last 800,000 years), Earth’s climate has been dominated by variations both on orbital (tens to hundreds of thousands of years) and millennial timescales. Each of these modes of variability has received significant enquiry and yet each remains enigmatic in its underlying mechanisms. Recently however, progress has been made in understanding the potential interplay between millennial-scale climate variability (involving abrupt changes in ocean circulation and the so-called bipolar seesaw) and the mechanism of deglaciation (the transition from glacial to interglacial conditions). This project aims to provide quantitative information about this link in order to learn more about the mechanism of glacial termination. Specifically, we aim to quantitatively differentiate between those millennial-scale oscillations that coincide with glacial terminations and those that do not and to determine the precise temporal relationship between seesaw oscillations, glacial terminations and changes in orbital configuration. In so doing we aim to make progress on the following outstanding questions: Are bipolar seesaw oscillations a necessary feature of glacial terminations or merely a complicating factor? Are seesaw oscillations themselves sufficient to drive glacial termination or are there particular characteristics of terminal oscillations that promote deglaciation? What are the connections between varying boundary conditions (insolation, ice volume, atmospheric CO2 concentration) and the nature of seesaw oscillations? Is there an underlying orbital parameter that ultimately controls the occurrence of glacial terminations? The project will involve a combination of quantitative data analysis and the application of state-of-the-art computer models of the climate system. Candidates for the post should have a PhD in natural sciences, experience in numerical Earth system modelling and quantitative data analysis and a strong interest in climate science. The project is led by Dr Stephen Barker (Cardiff University, UK) in close association with Dr Gregor Knorr (Alfred Wegener Institute, Germany) and Prof Andy Ridgwell (University of Bristol, UK). The post will involve extended visits to Germany for training and interaction with Co-I Knorr.
