Massive 'Dead Zone' in the Arabian Sea
A massive "dead zone" in the Arabian Sea is the largest in the world, a new study reveals.
Dead zones are oxygen-starved ocean regions where few organisms can survive. They emerge in ocean depths ranging from 650 to 2,600 feet (200 to 800 meters), when influxes of chemical nutrients — typically from human pollution — spur algae growth, which sucks up oxygen. A significant oxygen-deprived region has bloomed in the Gulf of Oman for decades, but it was last surveyed in the 1990s.
Recently, researchers returned to the Gulf of Oman and found that the dead zone has expanded far more than expected, raising serious concerns about the future of local fisheries and ecosystems, researchers reported in a new study.
