Coring Three Lakes

Gygaia Projects

In the last week of October, a small group of Gygaia Projects team members took advantage of a new collaboration with Dr. Çetin Şenkul of Süleyman Demirel University (İsparta, Turkey) and his PhD students Mustafa Doğan and Yunus Bozkurt, to take sediment cores for paleoenvironmental analyses from three desiccated lakes in Manisa.

The first two of these – Yemişçigöl and Eğrigöl – dried up completely within recent memory, and at least the former had been a marshy wetland canalized already in late Ottoman times (for which subject see a forthcoming publication by Semih Çelik and Christina Luke which will be announced on this site when published).

The recent tragic and full desiccation of Lake Marmara, as of August 2021, provided the third opportunity to collect sediment cores.

The desiccated lakebed of Lake Marmara (with Kaymakçı in the lower right foreground; August 2021).

Several coring projects had already recovered and published core data from Lake Marmara, but – given the presence of water in the lake until recently – none used truck-mounted coring methods capable of penetrating hardened strata and preserving the long, continuous sediment columns essential for longitudinal paleoenvironmental analyses (sedimentology, palynology, etc.).

We were grateful for the opportunity to collaborate and look forward to sharing results when possible!

Look forward to more posts from Gygaia Projects soon!
