Aquatic sources of carbon dioxide and methane are globally significant, but unknown for flooded drylands. The aim of this project is to use an innovative combination of well-integrated methodologies to determine if flooded drylands release large amounts of carbon dioxide and methane. This project is significant because this release of carbon dioxide and methane has not previously been accounted for and may change the magnitude of the global terrestrial carbon dioxide sink and account of some of the planet’s missing sources of methane. The outcomes of this project will make a significant contribution to our understanding of the global carbon cycle and earth climate system, and inform future management of these systems.

二氧化碳和甲烷的水生来源在全球范围内都很重要，但对被水淹没的旱地却不为人知。该项目的目的是采用一种创新的综合方法组合，以确定被水淹没的旱地是否释放大量的二氧化碳和甲烷。这一项目意义重大，因为二氧化碳和甲烷的这种释放以前没有被考虑在内，可能会改变全球陆地二氧化碳汇的规模，并考虑到地球上一些缺失的甲烷来源。该项目的成果将为我们对全球碳循环和地球气候系统的理解做出重大贡献，并为这些系统的未来管理提供信息。
