Industrial Dust Reduces Pacific Ocean Oxygen

Staff of the Georgia Institute of Technology (USA) found that the industrial wastes have an impact on areas of the ocean, that are thousands of kilometers away from production, leading to oxygen deficiency.

Industrial Dust Reduces Pacific Ocean Oxygen

The researchers created a model that takes into account the composition of the Earth's atmosphere, biogeochemical cycles and ocean circulation. With its help they established that the industrial dust that was released into the northern regions of the Pacific, moved over to the east along the coast, and then returned to the west along the line of the equator.

This dust settled on the surface of the water contained a lot of iron and nitrogen, which provokes very active photosynthesis. As a result, the phytoplankton produces an excessive amount of organic matter settling on the bottom and causing lack of oxygen in deep layers. Periodically, these layers are raised and lead to the death of fish, crabs and other sea creatures in the coastal areas.
