AGU Fall Meeting, Washington, DC


Hello, and welcome to my website. My name is Bas de Boer and I am a postdoctoral researcher at the IMAU (Institute for Marine and Atmospheric research Utrecht). As of 15 January 2019, I work as a Postdoc at the VU Amsterdam. I am using sophisticated 3-D ice-sheet models to simulate ice volume over the past millions of years. These models have been coupled to a sea-level model, to simulate regional sea-level patterns over the globe. My current project focusses on simulating the climate, ice sheets and sea level for the Late Pliocene, a warm period about 3.3 to 3 million years ago. During this time it is widely thought that both the Greenland and Antarctic ice sheets are smaller compared to their present size and hence where responsible for a rise in global sea level. In this project I am aiming to get a more detailed picture of the interaction between ice sheets and a wamer-than-present climate and also analyse regional sea-level changes related to melting of these ice sheets.

INQUA-PAGES iSLR18 conference

Inpact of sea-level rise from past to present

From 26-29 August 2018 Utrecht University hosted an international conference aiming to facilitate scientific exchange between early-career researchers from a broad range of disciplines working with sea-level change. Apart from the scientific programme a Science and Society evening session was held on Monday 27 August.

On behalf of Utrecht University, IMAU and the Department of Physical Geography were involved in the organisation of the conference. For more information, check out the conference website and a short summary here.

NWO-Veni project

A consensus of past climate and regional sea-level change
My research is currently funded by NWO Earth and Life Sciences.

The Antarctic and Greenland ice sheets will be significant contributors to sea-level rise during and beyond this century. An increase in sea level will have considerable impact on ecosystems, the vulnerability of the coast and on society. A better understanding of the responses of the ice sheets to a warming climate is 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.

Within this project, I will use a unique ice-sheet - sea-level numerical model and couple this to a high-end numerical climate model for the Late Pliocene to for the first time simulate the time varying climate and ice volume simultaneously. Geological data for the data-rich last glacial cycle will be integrated into the modelling framework to serve as a constraint on modelled sea-level change over the globe. Accordingly, combining models and data will reduce model uncertainties of sea-level change.
