This year, the dead zone in the Gulf of Mexico entered into the top third of largest dead zones in records that go back 38 years, the National Oceanic and Atmospheric Administration said. The ...
The oxygen concentration in the bottom layer may then become low enough for hypoxia to occur. Areas particularly prone to this include shallow waters of semi-enclosed water bodies such as the Waddenzee or the Gulf of Mexico, where land run-off is substantial. In these areas a so-called "dead zone" can be created.
Firstly, it occurs in coastal zones where eutrophication has driven some quite rapid (in a few decades) declines in oxygen to very low levels. [2] This type of ocean deoxygenation is also called dead zones. Secondly, ocean deoxygenation occurs also in the open ocean. In that part of the ocean, there is nowadays an ongoing reduction in oxygen ...
Scientists prepare to collect near-bottom water aboard the R/V Pelican to verify oxygen measurements used to determine the size of the Gulf of Mexico hypoxic zone. (NOAA/LUMCON/LSU) A "dead zone ...
A dead zone is an area of water that cannot sustain aquatic life because the oxygen levels are low or depleted. The scientific term for a dead zone is called hypoxia, which in Latin means "too ...
