[1] 在本文中，我们报告了英吉利海峡 13 个断面的地表水中二氧化碳分压 (pCO(2)) 的分布，涵盖四个季节。 pCO(2) 的空间和时间变化受到初级生产（5 月至 6 月）、有机物降解、温度变化和淡水输入的复杂组合的控制。初步的海-气二氧化碳交换计算表明，该海峡并不是大气二氧化碳的主要汇，从大气耦合的角度来看，该海峡可能是中性的。这主要与相对较低的有机碳输出和/或埋藏以及强烈的底栖钙化有关。
[1] In the present paper we report the distribution of the partial pressure of CO2 (pCO(2)) in surface waters along 13 transects in the English Channel, covering the four seasons. The spatial and temporal variability of pCO(2) is controlled by a complex combination of primary production (from May to June), degradation of organic matter, temperature change, and freshwater inputs. Preliminary air-sea CO2 exchange computations suggest that the Channel is not a major sink of atmospheric CO2 and is probably neutral from the point of view of atmospheric coupling. This is mainly related to a relatively low export and/or burial of organic carbon and intense benthic calcification.
