The aquatic and terrestrial carbon cycles are intrinsically linked with changes in terrestrial carbon dynamics altering the aquatic carbon cycle. However, the main methodology employed to assess land-atmosphere carbon dioxide fluxes fails to account for carbon losses through subsurface lateral exports of carbon via groundwater. This project aims to resolve the importance and drivers of this pathway, along with the ultimate fate of the carbon once it reaches the aquatic environment. This project aims to contribute to closing a significant gap in our understanding of terrestrial-aquatic carbon cycling and will quantify a potentially important yet poorly understood component of regional and global carbon budgets.

水生和陆地碳循环与改变水生碳循环的陆地碳动态变化有着内在的联系。然而，用于评估陆地-大气二氧化碳通量的主要方法没有考虑到通过地下水侧向输出碳的碳损失。该项目旨在解决这一途径的重要性和驱动因素，沿着碳到达水生环境后的最终命运。该项目旨在缩小我们对陆地-水生碳循环的理解方面的重大差距，并将量化区域和全球碳预算中一个潜在的重要但知之甚少的组成部分。
