The Intertidal Zone*

- The zone closest to the shore, sometimes referred to as the shoreline. The intertidal zone is usually above water at low tide and below water at high tide.

The Intertidal Zone

The Neritic Zone*

- Above the continental shelf. The neritic zone is the area of the ocean extending from the low tide mark to the end of a continental shelf.

The Neritic Zone

The Deep Zone*

- Sometimes referred to as the oceanic zone. The deep zone begins offshore, starting at the end of a continental shelf. The deep zone is 65% of all ocean water.

The Deep Zone

Continental Shelf*

- The submerged border of a continent that slopes gradually down.

Phytoplankton*

- Microscopic organisms that inhabit the upper, sunny layers of oceans and most fresh water. Phytoplankton produce most of the world’s oxygen.
