What is Gulf Hypoxia?
Hypoxia, or oxygen depletion, is an environmental phenomenon where the concentration of dissolved oxygen in the water column decreases to a level that can no longer support living aquatic organisms. Hypoxia in the northern Gulf of Mexico is defined as a concentration of dissolved oxygen less than 2 mg/L (2 ppm).

What causes the dead zone in the Gulf of Mexico?
The dead zone is caused by nutrient enrichment from the Mississippi River, particularly nitrogen and phosphorous. Nitrogen and phosphorous enter the river through upstream runoff of fertilizers, soil erosion, animal wastes, and sewage.
Why are dead zones bad for humans?
When the algae eventually dies, the oxygen in the water is consumed. Elevated nutrient levels and algal blooms can also cause problems in drinking water in communities nearby and upstream from dead zones. Harmful algal blooms release toxins that contaminate drinking water, causing illnesses for animals and humans.

What can be done to stop dead zones?
Managing Runoff to Reduce the Dead Zone
- Nutrient management: The application of fertilizers can vary in amount, timing, and method with varying impacts on water quality.
- Cover Crops: Planting of certain grasses, grains or clovers, called cover crops can recycle excess nutrients and reduce soil erosion, keeping nutrients out of surface waterways.

What is the dead zone in Gulf of Mexico?
The hypoxic zone in the northern Gulf of Mexico is an area along the Louisiana-Texas coast, where water near the bottom of the Gulf contains less than two parts per million of dissolved oxygen, causing a condition referred to as hypoxia. Each summer, the size of the hypoxic zone is measured.

Can you punch a shark in the nose?
“If… a shark bites you, what we recommend is you should hit the shark in the eye, in the nose, or stick your hand in the gills,” says Chris Lowe, of the California State University Long Beach Shark Lab, in an instructional video. “Those are all sensitive tissues and quite often it causes the shark to release.”
What causes hypoxia in the ocean?
In ocean and freshwater environments, the term “hypoxia” refers to low or depleted oxygen in a water body. Hypoxia is often associated with the overgrowth of certain species of algae, which can lead to oxygen depletion when they die, sink to the bottom, and decompose.
