Paleoenvironmental Research Lab
at the University of Gdansk is looking for a PhD student interested in #paleolimnology #lakes #sediments #geochronology #geology #sedimentology #geochemistry
#phdchat
Project: Varved sediments have been established as one of the most prominent environmental archives. Lake Synevyr is the first site in the Eastern Carpathians where varved sediments were discovered, providing the basis for completely new reconstructions of the Holocene environmental changes in this region. With our project we address the following research questions: What was the dynamics of climate change / human impact in the region during the transition from a nature-dominated to a human-dominated environment? Is the most recent time unusual within the Holocene? We aim to (1) reconstruct local vegetation changes, soil erosion and lake productivity since lake initiation to the present, and (2) evaluate the interactions between climate variability / human activity, and their impact on the lake environment. Contact: The project is led by Prof. Wojciech Tylmann form Paleoenvironmental Research Laboratory, Department of Geomorphology and Quaternary Geology. Candidates are requested to send (in one PDF file!) their CV including scientific achievements, motivation letter, references from the supervisor of their MSc thesis or immediate superior, and consent to the processing of personal data to the following email address: wojciech.tylmann@ug.edu.pl. The final deadline for submissions is July 25th at 3:00 pm, and the competition results will be announced by July 31th, 2025. Any questions regarding both the scientific scope of the project and the organizational-financial aspects can be directed to the same email address (wojciech.tylmann@ug.edu.pl).

Our new paper in @pnas.org shows how the first Polish dynasty established a state and later, due to social and ecological imbalance, orchestrated its colapse.
We used #palaeoecology #archaeology #historical sources & #numismatics to show this complex process. www.pnas.org/doi/10.1073/...

Two projects I'm involved with are looking for PhD students:
1. Formation of #authigenic #carbonates at the last glacial maximum to Holocene interglacial transition.
2. Understanding the effect of #ClimateChange by using the east #Mediterranean as a natural laboratory.

My colleague Luyao led this really interesting paper where we compiled lake sediment records of Phosphorus over the past 10000 years. We found evidence of major impacts to the P cycle by humans thousands of years ago.
