Dead zones are available worldwide(connect to NASA dead zone page). The Gulf dead zone is among the largest on the planet. Marine dead zones are available in the Baltic Ocean, Black Ocean, from the coast of Or, as well as in the Chesapeake Bay. Dead zones can also be present in ponds, for example Lake Erie.

What Can Cause the Dead Zone?

The dead zone is because nutrient enrichment in the Mississippi River, particularly nitrogen and phosphorous. Watersheds inside the Mississippi River Basin drain a lot of the U . s . States, from Montana to Pennsylvania and increasing southward across the Mississippi River. The majority of the nitrogen input originates from major farming states within the Mississippi River Valley, including Minnesota, Iowa, Illinois, Wisconsin, Missouri, Tennessee, Arkansas, Mississippi, and Louisiana. Nitrogen and phosphorous go into the river through upstream runoff of fertilizers, soil erosion, animal wastes, and sewage. Inside a natural system, these nutrients aren’t significant factors in algae growth since they’re depleted within the soil by plants. However, with anthropogenically elevated nitrogen and phosphorus input, algae growth is not limited. Consequently, algal blooms develop, the meals chain is altered, and dissolved oxygen in the region runs out. How big the dead zone fluctuates seasonally, because it is exacerbated by farming practices. It’s also impacted by weather occasions for example flooding and hurricanes.
