马尔马拉区域是调查黑海和东地中海之间与气候模式有关的相互联系和环境变化的一个关键地区。伊兹尼克湖是一个寡盐湖，位于马尔马拉海东南部。要破译沉积物柱中记录的长期信号，需要更好地了解现代湖泊周围的过程。季节性湖沼调查与地球化学和沉积学分析相结合。伊兹尼克湖是一个碱性、温暖的单胞湖。在温暖的季节，温跃层建立在15米和20米水深之间。厌氧底层水在春季混合。在夏季的白化事件中，地表水流变得可见，这与地表沉积物的地球化学代理中发现的空间积累模式相对应。
The Marmara region is a key area to investigate the interconnection and environmental changes between the Black Sea and the Eastern Mediterranean related to climate patterns. Lake Iznik is an oligohaline lake located in the southeast of the Marmara Sea. To decipher the long-term signals recorded in the sediment column requires better understanding of the processes in the modern lake environs. Seasonal limnological investigations were paired with geochemical and sedimentological analyses. Lake Iznik is an alkaline, warm monomictic lake. During warm seasons, a thermocline is established between 15 m and 20 m water depth. Anaerobic bottom water is mixed during spring. Surface water currents became visible during a whiting event in the summer, corresponding with spatial accumulation patterns found in geochemical proxies of the surface sediment.
