Earth System Evolution

This theme aims to develop and test novel methods for characterizing complex interactions from geological data, and to seek new fundamental insights into the coupling between Earth system components across time scales.

Earth scientists increasingly recognize the need to study not only the components of the Earth system (lithosphere-hydrosphere-atmosphere-biosphere), but also the complex and evolving nature of their coupling. Understanding these interconnections is crucial for global environmental projections, including climate tipping points, ocean acidification, sea level rise, biodiversity loss and mass extinctions. Although unprecedented in the history of human civilization, such dramatic upheavals have occurred repeatedly throughout Earth's history. Researchers therefore turn to the geological record for insights into causes, consequences, and time scales of global change in the past.

In this project, we will develop and test information-theoretic techniques for quantifying complex interactions from sparse data, and apply these methods to a wide range of geological records of Earth system history over thousands to billions of years. The themel involves other research groups at the Department of Earth Science and the Centre for Geobiology, UiB, as well as an extensive network of international collaborators.
