Summary- Scientists have found a large reduction in the amount of the coldest deep ocean water called Antarctic Bottom Water. Two oceanographers from NOAA and the University of Washington find that Antarctic Bottom Water has been disappearing at an average rate of about eight million metric tons per second over the past few decades. This is equivalent to about fifty times the average flow of the Mississippi River. Antarctic Bottom Water is formed in a few distinct locations around Antarctica. Where seawater is cooled by the overlying air and made saltier by ice formations.

Critique- The coldest deep ocean water is called Antarctic Bottom Water.

Impact- Antarctic Bottom Water has been disappearing at an average rate of about eight million metric tons per second over the past few decades.
