The ocean is composed of one water mass and has basin-scale current, which is accompanied by marine organisms. At smaller scale, such as mm or micrometer, there should be also turbulence which is also accompanied with microorganisms. By conducting field research at Tokyo bay, it was clarified that there were numerous small-size particles that were not-homogeneously distributed in the water column. Also by applying molecular techniques, the differences among microbial community structures among different Niskin bottles that were operated simultaneously at the same depth.

海洋由一个水团组成，有盆地规模的洋流，并伴有海洋生物。在较小的尺度，如毫米或微米，也应该存在湍流，湍流也伴随着微生物。通过在东京湾进行实地研究，发现水体中存在大量不均匀分布的小尺寸颗粒。并利用分子技术，研究同一深度同时操作的不同Niskin瓶之间微生物群落结构的差异。
