河口在将河流输送的大量碳转移到邻近的沿海地区之前，对它们进行了深刻的转化。由于沉积物和水体中的异源碳发生复杂的生物地球化学改造，二氧化碳和甲烷被排放到大气中。我们尝试综合有关河口环境中二氧化碳和甲烷生物地球化学循环的现有知识，特别强调与大气的交换。与 CH4 不同，与全球碳循环的其他组成部分相比，全球从河口排放到大气中的 CO2 数量显着
Estuaries profoundly transform the large amounts of carbon delivered from rivers before their transfer to the adjacent coastal zone. As a consequence of the complex biogeochemical reworking of allochthonous carbon in the sediments and the water column, CO2 and CH4 are emitted into the atmosphere. We attempt to synthesize available knowledge on biogeochemical cycling of CO2 and CH4 in estuarine environments, with a particular emphasis on the exchange with the atmosphere. Unlike CH4, the global emission of CO2 to the atmosphere from estuaries is significant compared to other components of the global carbon cycle
