Bas de Boer started his career at Utrecht University where he did his PhD at the Institute for Marine and Atmospheric research Utrecht (IMAU) on reconstructing ice volume, sea level and CO2 over the past 40 million years under the supervision of Dr. Roderik van de Wal and Prof. Lucas Lourens (UU Earth sciences). After his graduation in early 2012, he did a postdoc at the same institute focussing on a more detailed reconstruction of ice volume over the past 5 million years and the interaction between ice and sea level over the past glacial cycles.

Bas joined the University of Leeds in July 2015 with a Marie Sklodowska-Curie grant for a project on transient climate, ice sheet and sea level model during the late Pliocene. He left Leeds in September 2016 to work again in Utrecht, but continuous the collaboration with his colleagues in Leeds. He is a lead investigator in the Pliocene Ice Sheet Modelling Intercomparison Project (PLISMIP).

Research Interests

My main interests are the interactions between ice sheets, sea level and the climate over long times scales, primarily over the past 5 million years. Currently, my research will focus on the interactions during the past glacial cycles and a detailed examination of the Late Pliocene climate.

As an ice-sheet, sea-level modeller, I am currently using 3-D ice-sheet models coupled to a global sea-level equation model that can simulate ice-sheet and sea-level change simultaneously over multiple glacial cycles.

Project details

Project title

Pliocene Transient Climate Modelling


This project is carried out in collaboration with Prof. Alan Haywood, Dr. Stephen Hunter, Dr. Lauren Gregoire and Dr. Aisling Dolan.

Project outline

The Antarctic and Greenland ice sheets will be significant contributors to sea-level rise during and beyond this century. A better understanding of the responses of the ice sheets to a warming climate is evidently needed to make more rigorous predictions of the impact of regional sea-level variations. The Late Pliocene (3.264 to 3.025 million years before present) was a warm interval in the history of the Earth that can be used to gain a better understanding of the response of the ice sheets to a warming climate with CO2 levels close to or higher than present. Within this project, I will use an ice-sheet - sea-level numerical model and couple this to a numerical climate model for the Late Pliocene to simulate the time-varying climate and ice volume simultaneously.
