Independent UK - Swathes of oxygen-deprived water up to 100 miles long, unable to sustain any form of animal life, have been found in the Atlantic, scientists have said.
Researchers of the GEOMAR Helmholtz Centre for Ocean Research Kiel in Germany discovered the unexpectedly low oxygen environments several hundred kilometres off the coast of West Africa.
A paper, published in Biogeosciences, describes 100-mile-long eddies of swirling water spinning their way across the Atlantic for months at a time.
Dead zones are usually found in shallow bodies of water, such as lakes and shallow coastlines.
However, the swirling movement of the eddies found in the Atlantic ensures that no water can escape, so the oxygen supply is quickly used up
