Dead zone

The main problem this paper intends to discuss regards the Gulf of Mexico dead zone. This dead zone, which for the most part encompasses the water off the coast of Louisiana, becomes depleted in dissolved oxygen. The dead zone is an outcome of nutrient runoff into the Gulf from urban areas, wastewater treatment plants, and from atmospheric deposition, however, the majority comes from fertilizers used in agriculture around the Mississippi River Basin. The increase in nutrients has been affecting the

One World Essay: Dead Zone in the Gulf of Mexico Scientific Reasoning: The dead zone in the Gulf of Mexico is a human problem, like most other disasters. What this means is that once the place thrived and was ecologically balanced, but we tipped the balance slightly and wrecked havoc upon the environment. It has been noted to occur since the 1950’s and is ongoing. The reason that this dead zone occurs is because of a phenomenon known as eutrophication. Eutrophication is when there is an excessive

Dead zones are hypoxic zones that can occur naturally but recently are being created by human interference and any naturally occurring ones rapidly grow bigger due to outside influence.The main impact humans have that cause dead zones are the surplus of nutrients in the water, these come primarily from farms and drain into rivers and streams or as excess water that is dumped into a lake or river. All the nutrients allows huge amounts of algae to grow at a rapid rate and once there is no longer enough

Troubled Waters are mainly caused by dead zones. Dead zones are a specific area in a ocean that has dissolved oxygen. Dissolved oxygen means there is no oxygen in that area in the ocean. Every ten years the amount of dead zones have doubled and there is twice as many dead zones in the world right now. Sea animals are dying in those zones right now because they swim right up into them and they have no air to breath so they have to try to get out of the dead zone as fast as they can.The nutrient availability

system is getting destroyed too. What we don’t realize is that we are nature, we’re connected with nature industrial evalution nation turned as a resource. All this farming that people are doing and the carbon that is being made are making ocean dead zones. All the warm ocean causes it to increase the carbon dioxide. For example What does different concentrations of acid do to shells? When CO2 is absorbed by seawater chemical reactions occur that reduce seawater pH levels. Calcium carbonate minerals

the organisms in that area. This is what is known as a dead zone. What is your personal interest in the topic? This topic is interesting to me because it is a very local issue. I eat the seafood out of the Chesapeake, I fish in many of its tributaries, and I visit many sights built around this watershed. I live in Lancaster County which is focused on in many studies because

The National Oceanic & Atmospheric Administration (NOAA) explains that if this trend of eutrophication continues, what is known to be a “dead zone” will be created. According to the NOAA, the northern Gulf of Mexico is the second largest dead zone in the United States. The Gulf of Mexico is officially recognized as a hypoxic, or dead zone, because it has less than 2 ppm dissolved oxygen in accordance to the Microbial Life Education Resource’s website. The source of the gulf’s extensive

keep a watchful eye out for possible HABs are urged to report suspected HABs to their respective state environmental agency. (Chesapeake Bay Programs) (Article 1) Lastly, I will explain the dead zone of the chesapeake Bay. Excessive Nitrogen and Phosphrous pollution from human activities cause “Dead Zones” , which are areas with low amounts of oxygen. With little or no oxygen, fish, crabs, oysters, and other aquatic animals literally suffocate. Further excess in nutrients also fuels the growth

Ocean to toss their waste without consequences. The formation of dead zones has been intensified by the increase runoff of fertilizers and the burning of fossil fuels. Enhanced primary production causes algae to bloom at a constant rate creating a layer near the surface. This layer acts as a roof to vegetation below resulting in a lack of oxygen which organisms use to live. According to Robert Diaz and Rutger Rosenberg, “Dead zones have now been reported from more than 400 systems, affecting a total

invertebrates? A study in Biology Dusty Vincer, Advisor by Shruti Gajbhiye During the recent Deepwater Horizon oil spill, millions of gallons of oil were dispersed in the Gulf of Mexico in the same area known as the Gulf of Mexico Hypoxic Zone. The hypoxic zone along the Gulf Coast contains less than the normal amount of dissolved oxygen, at two parts per million. The little to no oxygen is theorized to be caused by excess nutrients from the Mississippi River along with the stratification of the
