Mangroves are considered an important global carbon sink. However, there is an imbalance of about 50 per cent in mangrove carbon budgets. This project will resolve whether advective pore water exchange and associated underground respiration represents the missing component of mangrove carbon and greenhouse gas budgets. This innovative project will examine the previously overlooked concept that crab burrow flushing is a major driver of biogeochemical reactions in mangroves. It will use a combination of new experimental and modelling approaches and will contribute to closing a significant gap in our understanding of the coastal carbon cycle.

红树林被认为是全球重要的碳汇。然而，红树林碳预算存在约50%的不平衡。该项目将解决平流孔隙水交换和与之相关的地下呼吸是否代表红树林碳和温室气体预算中缺失的部分。这个创新的项目将检验以前被忽视的概念，即蟹穴冲洗是红树林生物地球化学反应的主要驱动力。它将使用新的实验和模拟方法相结合，并将有助于弥合我们对沿海碳循环的理解上的一个重大差距。
