This… The pelagic zone can be thought of in terms of an imaginary cylinder or water column that goes from the surface of the sea almost to the bottom. The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth. Salinity variations in the open ocean normally ranges from 33 to 38 percent.
