An international team looks back 12 million years for clues about the formation of these vast areas where no life can survive A satellite image of the Northern Gulf of Mexico, where 'dead zones' can ...

This one is very much real. For decades, an oxygen-depleted dead zone that is harmful to sea life has appeared in the Gulf of Mexico in a region off the coasts of Louisiana and Texas. This year ...

A new study says the Chesapeake Bay could face marine heat waves for nearly a third of the year by 2100, impacting wildlife, ...

When the oxygen levels go down, dead zones will expand. These are areas of the ocean where the water quality is too poor to sustain life. Pollution will only add to the devastation unless we stop it.

These algae blooms then die and sink to the bottom of the ocean, depriving fish and other underwater creatures of the oxygen they need to survive. This creates an aptly named "dead zone." ...

“That’s where in many parts of the ocean — including the eastern Pacific where scalloped hammerheads live — there is a growing oxygen dead zone where the oxygen concentration in the water is ...

The Chesapeake Bay area could have up to a third of the year under marine heat wave conditions by the end of the century, according to a new study from the Virginia Institute of Marine Science.

The findings are published in PNAS Nexus. Persistent oxygen-depleted zones in the ocean are relatively well studied in the temperate zone, but little is known about these unique ecosystems in the ...
