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.

Pelagic organisms are grouped as plankton or nekton. Nektonic critters are capable of swimming against a current and include most species of sharks, rays, fish, seals, sea lions, and whales.he bacteria use up a lot of dissolved oxygen in the seawater so that areas of red tide may have little, or no, oxygen. If oxygen levels are low this can affect organisms in the water, such as fish. If the marine organism needs dissolved oxygen and cannot leave the red tide then it may suffocate and die.
