Searching for the Right Erratic Boulder

“I don’t want to look at stones anymore, they don’t say anything” [1]......but what if they do have something important to say to us?


I would like to share some experiences with you related to our studies of erratic boulders (Fig. 1) in north Poland. Erratics (chaotically dispersed in some regions) are stones of glacial origin. This post focuses on how to find the right erratic boulder to “catch” the ice sheet from Pleistocene – the geological epoch which lasted from about 2.5 million to 11 thousand years ago, often referred to as the Ice Age.


Glaciers and ice sheets grew and shrunk many times in response to past climate changes. It is important to know when and how fast it happened, to be able to predict future climate behaviour. But how can we date and reconstruct fluctuations of the Pleistocene ice sheets which disappeared completely ca 10 000 years ago? In fact, stones may be the answer!

Attending the EGU General Assembly for the first time

The European Geosciences Union (EGU) is a union comprised of 12,500 scientists all over the world. Every year, the general assembly is organised in Vienna and is visited by a great number of people active in Geosciences. This year, a total of 15,000 people from 106 countries, promotional stands and conference staff not included, occupied the Austria Center Vienna from Sunday 7 until Friday 13 April. I was there for the first time, and as a Quaternary entomologist I felt a bit like an outsider.




When I initially applied for the EGU I had real difficulties finding a session which could include my research. My PhD research focuses on using subfossil beetle remains to reconstruct climate and landscapes to set up baselines in questions of nature and landscape conservation. This research topic would technically fall under Biogeosciences. However, none of the session descriptions seemed relevant for my PhD research. Yet I w…
