In this study, we investigated the paleoclimatic and geochemical changes in the Late Holocene period in Lake Akgöl (Terme), located in Samsun, Black Sea. Approximately 19% of the lagoons in the coastal regions of Turkey are located on the Black Sea coast. Among these lagoons, Akgöl Lake is a lagoon lake located in the east of Yeşilırmak Delta. Water areas called lagoons or coastal barrier lakes are special ecosystems that are mostly ecologically important, extending parallel to the coast, their connection with the sea is provided by one or more narrow openings. Since coastal barrier lakes are very sensitive to environmental effects, it is clear that they have been exposed to limnological and climatic changes in the past. Using the core drilling, we retrieved a gravity sediment core, Akgöl-02 from the sediment on the bottom of the Akgöl which provides a high-resolution record of environmental change. The purpose of this study is to examine paleoenvironmental changes that impact the region of the Black Sea, therefore, we analysed a 193-cm-long sediment core using multi-proxy analyses with high resolution to demonstrate the paleoclimatologic and paleoenvironmental changes in Akgöl sediment in Terme (Samsun, Türkiye) during the last 2600 years. The preliminary results of the multi-proxy analysis (XRD, XRF, grain size) suggest that the climate of the region was cooler/drier in during 2600 cal yr BP. This study was granted by İstanbul Technical University (İTU) Scientific Research Projects (BAP) with project number MYL-2022-43649.
