What is an oxygen minimum zone?
OceanographyMarine environment
Quick Answer
An oxygen minimum zone is a layer of the ocean where dissolved oxygen is extremely low. These zones often occur between the sunlit surface and the deep ocean.
The Full Story
Oxygen minimum zones, or OMZs, form where oxygen is consumed by decomposition faster than it is replaced by circulation. They are especially common in areas with high biological productivity and limited mixing, such as parts of the eastern Pacific and northern Indian Ocean. Many animals avoid them, and only specially adapted organisms can tolerate the conditions. As oceans warm and stratification increases, some OMZs may expand.
