Red circles show the location and size of many dead zones (in 2008). Black dots show dead zones of unknown size. The size and number of marine dead zones—areas where the deep water is so low in dissolved oxygen that sea creatures cannot survive (except for some specialized bacteria)—have grown in the past half-century.

The older hypothesis is that the Dead Sea lies in a true rift zone, an extension of the Red Sea Rift, or even of the Great Rift Valley of eastern Africa. A more recent hypothesis is that the Dead Sea basin is a consequence of a "step-over" discontinuity along the Dead Sea Transform, creating an extension of the crust with consequent subsidence.
The dead zone is also bigger than the state of Rhode Island, which is approximately 1,500 square miles. ... When life is not sustainable in the sea, it also impacts life on land.
A 'dead zone' off the Gulf coast is larger than NOAA predicted. The massive area poses danger to marine life, and recovery could take decades. A 'dead zone' is growing in the Gulf of Mexico.
The Atlantic Ocean is teeming with life, but for the first time researchers have discovered dead zones in these waters - areas low in both oxygen and salinity - off the coast of Africa. Fish can't ...
Anoxic basins exist in the Baltic Sea, [6] the Black Sea, the Cariaco Trench, various fjord valleys, and elsewhere. [7] Eutrophication has likely increased the extent of anoxic zones in areas including the Baltic Sea, the Gulf of Mexico, [8] and Hood Canal in Washington State. [9]
An international committee evaluated different ideas [5] and came to the conclusion that large-scale engineering approaches are not able to add oxygen to the extremely large dead zones in the Baltic Sea without completely changing the Baltic Sea ecosystem. The best long-term solution is to implement policies and measures to reduce the load of ...
