Title:Water Depth

Explanation of Topic (Definition, Key Points, Details)
 * Water Depth is measurement of a water body from the surface to the top the bottom sediments. Water depth can vary substantially within a water body according to its morphology.
 * The measure water depth is to use a weighted Secchi disk. The Secchi disk is attached to a string that is marked in one foot increments. The weighted disk is placed down until it the bottom. Then you measure the top.

Ocean has many water depth layers one of the layers is the pelagic layers. In the pelagic layer it where the animals float freely. In the aphotic part of the pelagic zone is has a lot of plankton like phytoplankton, zooplankton, and nekton. It has some tuna, sea turtles, and dolphins. The abyssal zone it inclu des the deep-ocean floor, such as abyssal plains. It has extremely high water pressure, it has low temperature, no sunlight, and sparse life. All the foods that go to th e bottom comes from the top of the surface. Some of the food is form from the rain steadily come down. Other food arives as large things of organisms that come from the surface. This stuff supply meals for actively searching fish such as the grenadier, tripodfish, and hagfish. This is what water depth is about and the other zones that in the water depth.
