Hypoxia means low oxygen and is primarily a problem for estuaries and coastal waters. Hypoxia can be caused by a variety of factors, including excess nutrients, primarily nitrogen and phosphorus, and waterbody stratification layering due to saline or temperature gradients. These excess nutrients can promote algal overgrowth and lead to eutrophication. As dead algae decompose, oxygen is consumed in the process, resulting in low levels of oxygen in the water. Diagram of Eutrophication. In addition to the saline gradient caused where the freshwater and saline water meet, the freshwater is warmer than the deeper ocean water, further contributing to the stratification. This stratification prevents the mixing of oxygen-rich surface water with oxygen-poor water on the bottom of the Gulf.
Algal blooms themselves can cause problems, as in Florida last summer when several beaches were closed after they became coated in foul-smelling green slime. Relatively little effort has been undertaken to control nonpoint source pollution, with waterways and fisheries around the country suffering as a result. Less mobile or immobile animals, such as mussels or crabs, cannot move to waters with more oxygen and are often killed during hypoxic events. The legislation determined that pollution from point and nonpoint sources should be minimized, however it can be difficult to identify and reduce nonpoint source pollution such as fertilizer runoff from agricultural operations. What Causes the Dead Zone? Wastes and sediments flowing off lands affect natural concentrations of nutrients in water and the health of aquatic habitats. While reforming the meat industry’s unsustainable practices is a way to stop the spread of dead zones, change from within isn’t coming quickly enough. Food System 16 , flows in million pounds Life Cycle Impacts The energy used by a system is often a useful indicator of its sustainability. A girl places an American flag on the rubble of her grandparents’ home after it was destroyed by a tornado on April 30, in Louisville, Mississippi. This stratification prevents the mixing of oxygen-rich surface water with oxygen-poor water on the bottom of the Gulf.

Toxins from manure and fertiliser pouring into waterways are exacerbating huge, harmful algal blooms that create oxygen-deprived stretches of the gulf, the Great Lakes and Chesapeake Bay, according to a new report by Mighty, an environmental group chaired by former congressman Henry Waxman. It is expected that the National Oceanic and Atmospheric Administration Noaa will this week announce the largest ever recorded dead zone in the Gulf of Mexico.|

The floodwaters are laden with fertilisers washed from fields and factory farms. As spring turns to summer, excessive nutrients first drive a huge bloom of living plankton, then cause death on a gargantuan scale as a dead zone blossoms across the seabed.|

|Can suggest how the american diet affects gulf of mexico congratulate what words||Stories in the Gulf of Mexico. Heavy rains and melting snows washed massive amounts of nutrients—particularly nitrogen and phosphorus—from lawns, sewage treatment plants, farm land and other sources along the Mississippi River into the Gulf of Mexico. Once in the Gulf, these nutrients, which are required for plant and crop growth, trigger algae blooms that choke off oxygen in water and make it difficult, if not impossible, for marine life to survive.|
