[Dynamics of short term changes in the number of bacteria in the surface ooze layer and bottom water]

Statistically reliable short-term periodic changes in the number of bacteria were found in the surface ooze layer and, to a less extent, in the bottom water layer. The time of doubling of the bacterial number can be calculated approximately by counting bacterial cells in the ooze layer every day. An inverse correlation was established between the bacterial number in the surface ooze layer and in the bottom water layer.
