海洋被认为是N2O的重要来源，N2O是一种消耗臭氧层的温室气体。然而，北冰洋对全球N2O预算的贡献尚不清楚。本文介绍了加拿大海盆（CB）和格陵兰海盆（GSB）N2O浓度的首次观测结果。历史大气N2O记录和相应深度的N2O浓度在GSB之间的相关性表明，N2O的分布格局在这一地区的海气交换和水文过程占主导地位。CB中的N2O浓度的观测值与基于上述相关性的计算结果之间的一致性表明，CB中的N2O浓度最有可能是由N2O动力学和随后的水文过程中邻近的GSB。加拿大盆地中层水（CBIW）中的N2O浓度反映了人为的影响，而加拿大盆地深层水（CBDW）中的N2O浓度表明，CBDW可能是一个前工业化的“遗迹”。
The ocean is regarded as a significant source of N2O, which is an ozone-depleting greenhouse gas. However, the contribution of the Arctic Ocean to the global N2O budget is not yet known. Herein, the first observations of N2O concentrations in the Canada Basin (CB) and Greenland Sea Basin (GSB) are presented. A correlation between the historic atmospheric N2O record and N2O concentrations at the corresponding depth in the GSB suggests that the N2O distribution pattern is dominated by air-sea exchanges and hydrographic processes in this region. The consistency between the observed N2O concentrations in the CB and calculated results based on the above correlation suggest that the N2O concentrations in the CB are most likely dominated by N2O dynamics and subsequent hydrographic processes in the sea adjacent to the GSB. The N2O concentration in the Canada Basin Intermediate Water (CBIW) reflects anthropogenic influences, whereas the N2O concentration in the Canada Basin Deep Water (CBDW) suggests that the CBDW may be a preindustrial “relict.”
