    The most likely causes for the dead zone in the Great Lakes are the amount of phosphorus nitrogen and fertilizer running off into the lake. When the lake becomes rich in these nutrients and you add warmer temperatures into the equation you can expect an algal bloom. Once the bloom dies the decomposition depletes much of the oxygen in the water which is severe because of the size of the algal bloom. This coupled with things such as low water inflow and temperature of water are the most popularly…

This is a dead zone that is not naturally made like the largest dead zone that can be found in the lower portion of the black sea. The dead zone in the Gulf of Mexico has been caused by our…

    Introduction A dead zone is defined by when there is a body of water that lacks an adequate amount of oxygen to keep the species in it alive. With the low oxygen levels, species who have a lower tolerance of hypoxia like “...oysters, crabs, and finfish...” die while species with a higher tolerance like jellyfish have higher chances of survival and takes the place of where those low tolerance species used to be (Dybas 553). A major contributor to the creation of dead zones is an excess amount of…
