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.

PI计划确定自末次冰盛期以来气候变化对恒河-雅鲁藏布江/孟加拉扇系统陆地有机碳（OC）动态的影响。将使用沉积物成分和交付的无机代理和成对的稳定同位素/放射性碳测量，开发孟加拉扇沉积物和OC埋藏的亚千年分辨率记录。这些记录将使季风强度，古植被和OC停留时间的变化重建，深入了解气候变化，地貌响应，维管植物生物标志物和陆地OC动态之间的关系在孟加拉扇。拟议的工作将支持两名早期职业科学家，并将培训两名来自代表性不足的少数群体的本科生。该项目将通过与瑞士和德国研究人员的数据共享和综合努力加强国际合作关系。
