Among the 27 OMZ signals identified – indicated by ‘laminated’ layers in the core, reflecting undisturbed sediment laid down in the absence of living creatures – some of the dead zone intervals lasted for less than a thousand years, while in others the hypoxic conditions persisted for close to 40 millennia.
Does Lake Erie have dead zones?
In Lake Erie, the hypoxic zone can be as large as 10,000 square kilometers and alters the lake ecosystem from July to October. These low oxygen areas are often referred to as “dead zones,” because many mobile organisms leave the hypoxic zone, and many sessile organisms die without adequate oxygen.
Is Earth in a dead zone?
The majority of the world’s dead zones are along the eastern coast of the US, and the coastlines of the Baltic States, Japan and the Korean Peninsula. Notable examples include the Gulf of Mexico and the Baltic Sea. The Gulf of Mexico has a seasonal hypoxic zone that forms every year in late summer.
