ABSTRACT
Every spring, the dissolved oxygen levels in the coastal waters of the northern Gulf of Mexico decline and result in a vast region of oxygen-starved water that stretches from the Mississippi River westward along the Louisiana shore and onto the Texas coast.[1,2]
The phenomenon is known as hypoxia, but has been dubbed the ‘‘Dead Zone’’ by environmentalists and fishermen. The low, minimal, or non-existent oxygen levels drive away fish, shrimp, and crabs.
