The PIs plan to establish the effects of climate change on terrestrial organic carbon (OC) dynamics in the Ganges-Brahmaputra/Bengal Fan system since the Last Glacial Maximum. Sub-millennial resolution records of sediment and OC burial in the Bengal Fan will be developed using inorganic proxies of sediment composition and delivery and paired stable isotope/radiocarbon measurements. These records will enable reconstructions of variations in monsoon strength, paleo-vegetation, and OC residence time, providing insight into the relationships between climate change, geomorphic response, vascular plant biomarkers, and terrestrial OC dynamics in the Bengal Fan. The proposed work will support two early-career scientists, and will train two undergraduate students from underrepresented minority groups. The project will strengthen international collaborative ties through data sharing and synthesis efforts with Swiss and German researchers.

自上次冰川最大值以来，PIS计划建立气候变化对恒河/孟加拉风扇系统陆地有机碳（OC）动力学的影响。孟加拉风扇中沉积物和OC埋葬的近千禧一代分辨率记录将使用沉积物组成和递送的无机代理以及配对稳定的同位素/放射性碳测量结果开发。这些记录将能够重建季风强度，古植物和OC停留时间的变化，从而深入了解孟加拉风扇中气候变化，地貌反应，血管植物生物标志物和陆地OC动力学之间的关系。拟议的工作将支持两位早期职业科学家，并将培训来自代表性不足的少数群体的两名本科生。该项目将通过与瑞士和德国研究人员的数据共享和综合工作来加强国际合作关系。
