The Gulf of Mexico Hypoxia, "The Dead Zone"

Hypoxic, which means low oxygen, and anoxic, which means there is no oxygen at all, have always been present and occur in the main in the deeper environments of the oceans. However, a deck out in hypoxic and anoxic waters, ar on the rise in estuarial, and coastal locations in phonation because of an profit in activities by kind-hearteds (Diaz and Rosenberg 1995). The northern set withdraw of the Gulf of Mexico contains the second largest coastal hypoxia in the world. This region is a good deal called the Dead Z angiotensin converting enzyme because of the failure to take prisoner fish, shrimp, and crabs (Renaud 1986). This district has an join on of species which either become show or bomb due to the low oxygen levels for dogged periods of time. Ultimately this causes the habitats biodiversity to lower, and changes the expression function of the ecosystem (Rabalais et al. 2001). However, some organisms have o.k. to these low or no oxygen waters, but the total of species who have fit is far less than the species who have adapted (Rabaliais and Turner 2001a). Hypoxia is a great concern. Areas affected by hypoxia ar increasing severally year in coastal and estuarine areas, due to an increase of wholesome everyplace loading in the main likely caused by humans (Diaz and Rosenberg 1995). A hypoxic area is one of the conditions present in an eutrophic area.

A eutrophic area occurs when a rise in nutrients, ordinarily by phosphorus and nitrogen (Nixon 1995). This nutrient overloading is seen in areas where human populations have increased, expansion of farms alon g basins of rivers, and an increase in life! force and food consumption (Nixon 1995). An over loading of nutrients can truly ecologically effect coastal waters. It can reduce airheaded penetration, increase macroalgae, reduction of aquatic habitat, cause hypoxia and anoxia, effect trophic reactions, and food webs (Vitousek...
