What is the âDead Zoneâ? In coastal marine environments, âDead Zonesâ are regions where oxygen concentrations are very low. This condition of oxygen deficiency, known as hypoxia, is caused by an interaction between biological, chemical and physical factors. In the absence of sufficient oxygen, animals and plants either die or leave the dead zone. Although these affected waters are called dead zones, many bacteria can thrive in this region, feeding on the abundant food produced in the overlying waters. Hypoxia is a natural phenomenon that occurs periodically in coastal waters around the world.
