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.

Oxygen does not dissolve much in water, to overcome this problem the oxygen in the blood is stored in red blood cells. These contain haemoglobin which can combine with oxygen to form oxyhaemoglobin. The red blood cells contain the oxygen in the blood. The blood transports oxygen from the lungs to the rest of the body. Oxy-haemoglobin is bright red and haemoglobin is dark red, this is why veins look dark and why all the diagrams show veins in blue and arteries in red.
