The increase of spatial heterogeneities at night could be based upon vertical migration and the behavioural mechanisms of the planktonic organisms forming the patches.

A number of microplants with spherical, triangular, polyangular and boat-like shapes have been found both from the early Palaeoproterozoic Dashiling and Qingshicun Formations (ca. 2500- 2400 Ma) of the Doucun Subgroup of the Hutuo Group and the late Palaeoproterozoic Changzhougou and Chuanlinggou Formations (ca. 1800 -1700 Ma) of the Changcheng Group in North China. According to the features of these fossils, such as size, external shape and internal structure, they may belong to unicellular eucaryotic planktons.

在华北地区古元古代滹沱群豆村亚群的大石岭组、青石村组(约2500～2400 Ma)和长城群的常州沟组、串岭沟组(1800～1700 Ma)中存在着大直径的球形和形态呈三角形、多角形及船形微古植物，根据它们的大小、外部形态和内部结构等综合判别，它们可能属于单细胞真核浮游生物。

However,different periods were found in middle and bottom waters, due to the influences of tidal induced physical forcings such as resuspension and stratification.

表层叶绿素α浓度、微微型浮游生物和病毒丰度的周日波动呈现典型的半日周期(11-13小时)变化，而中层和底层由于沉积物再悬浮作用和水体层化现象的影响，波动周期与表层明显不同。

One type of plankton that seems to have great harvest possibilities is a tiny shrimplike creature called krill.
