利用Argo浮标资料，研究了北太平洋混合层的分布和时间变化。3月份混合层深度的空间分布表明，深层混合层主要集中在副热带环流的西北部。将Argo浮标测得的MLD分布与基于气候学的MLD分布相比较，在黑潮延伸体以北的区域，浮标测得的MLD比气候学的MLD浅270 m，而在黑潮延伸体以南的区域，浮标测得的MLD比气候学的MLD深330 m。通过对MLD的时间变化的研究发现，MLD的发展和消退的时间和幅度与黑潮延伸体南部的气候有明显的差异
The distributions and time changes of the mixed layer in the North Pacific are examined using the Argo floats data. Spatial distribution of the mixed layer depth (MLD) in March reveals that the deep MLDs are concentrated in the northwestern region of the subtropical gyre. Comparing the distribution of MLDs measured by the Argo floats to those based on the climatology, many MLDs detected by the floats in the region north of the Kuroshio Extension are shallower by up to 270 m than the climatology, but south of the Kuroshio Extension the former are deeper by up to 330 m than the latter. Investigating details of the time changes of MLD in selected small areas, both timing and amplitude of the development and retreat of MLD differs remarkably from the climatology in the south of the Kuroshio Extension
