在这里，我们使用一个高分辨率的生物地球化学和碳模式以及一个海洋模式来研究西北太平洋溶解无机碳(DIC)循环的季节变化。结果表明，大气-海洋CO2交换对DIC的贡献一般被各纬度地面的垂直混合所抵消，但存在一定的季节变化。亚北极地区的生物过程在地表明显，而在亚热带地区，这些过程发生在真光层内，然后DIC消费随纬度向南加深。这种生物过程的纬度差异导致了DIC分布的显著水平和垂直差异，并受到水平和垂直平流-扩散过程的调制。
Here, we investigate the seasonal variability in the dissolved inorganic carbon (DIC) cycle in the Northwest Pacific using a high-resolution biogeochemical and carbon model coupled with an operational ocean model. Results show that the contribution to DIC from air–sea CO2exchange is generally offset by vertical mixing at the surface at all latitudes, with some seasonal variation. Biological processes in subarctic regions are evident at the surface, whereas in the subtropical region these processes take place within the euphotic layer and then DIC consumption deepens southward with latitude. Such latitudinal differences in biological processes lead to marked horizontal and vertical contrasts in the distribution of DIC, with modulation by horizontal and vertical advection–diffusion processes.
