Black Sea Chemistry. But 650 feet below the surface of the Black Sea, there is no oxygen in the water for the wood bores to breathe, says Ballard. He compared the sea to a giant bathtub, with steep sides and no drain.Because the water of the Black Sea is very still, oxygen doesnât circulate to the bottom.The Black Sea, he says, is the perfect environment for preserving shipwrecks. The researchers predict there are perhaps hundreds still to be found.ecause the water of the Black Sea is very still, oxygen doesnât circulate to the bottom.

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.
