IPA-IAL symposium – France 2025

From October 6th to 10th, three of our representatives took part in the world’s most important congress dedicated to paleolimnological and limnogeological research. The event, organized by IPA and IAL, was held in the picturesque town of Aix-les-Bains by Lake Bourget in France. Our Department was represented by Alicja Bonk, Wojciech Tylmann, and Maurycy Żarczyński.

It was a week filled with fascinating presentations and equally valuable meetings. As the “varve team,” we also had the honor of attending the retirement celebration of our dear friend and one of the most prominent contemporary researchers of varved sediments – Bernd Zolitschka.
