Maximum numbers of bacteria generally occur at the pycnocline, where phytodetritus accumulates by sinking from the overlying euphotic zone.

The ocean can be divided into three density zones : the surface zone, the pycnocline, and the deep zone.
13.
The interface, called a pycnocline, between the brackish near-surface water and the denser water below supports internal wave motion.
14.
In addition, the physical properties in a pycnocline driven by density gradients also affect the flows and vertical profiles in the ocean.
15.
Below the mixed layer, a stable density gradient ( or pycnocline ) separates the upper and lower water which hinders vertical transport.
16.
Underlying these oxygenated waters and separated by a pycnocline, were anoxic and hypersaline bottom waters, which preserved organic matter as it accumulated.
17.
These changes can be connected to the transport of heat, salt, and nutrients through the ocean, and the pycnocline diffusion controls upwelling.
18.
A "'pycnocline "'is the cline or layer where the density gradient ( ) is greatest within a body of water.
19.
The base of the CIL is marked by a major pycnocline at about and this density disparity is the major mechanism for isolation of the deep water.
20.
Phytoplankton production is dramatically increased in these areas because the nutrient-rich water lying below the pycnocline is relatively close to the surface and is thus easily upwelled ( Mann and Lazier, 2006 ).
