Effects Of The Deepwater Horizon Oil Leak On The Gulf Of Mexico

Massive cleanup efforts were initiated within a few weeks of the spill and they continued at reduced levels for the next three years. Approximately 14% of the spilled oil was recovered by cleanup crews (Newsweek, p.50). As a result of these efforts and natural weathering, little oil from the spill remained in the affected area by 1992. However, according to the National Oceanic and Atmosphere Administration some oil residues are still found under the ocean surface in areas sheltered from wind and waves. Yet, these residues are highly weathered and the toxicity is reduced to levels tolerable by organisms in the water (7). Nonetheless, the magnitude and timing of the Exxon Valdez oil spill raised immediate concerns about possible effects on marine fish and wildlife and prospects that these effects might be long lasting.

On April 20th 2010 an explosion on an oil ridge of the coast of the Gulf of Mexico, was the cause of the greatest environmental disaster in history of the United States. This explosion took the lives of eleven men who were working on the ridge, and also ruptured an oil line, which dumped more than 4.9 million barrels of oil into the Gulf of Mexico. This oil spill significantly affected the wildlife of the gulf coast, killing hundreds of fishes, birds, and reptile that call the gulf coast home. The spill also affected global supply chain for major industries.

On April 20, 2010, one of BP’s drilling wells below the Gulf of Mexico exploded and caused a disastrous oil spill. Thousands of barrels of crude oil flowed into the gulf every day, causing widespread pollution in the Gulf of Mexico (Law Brain, n.d). The habitats of many bird species are threatened by this oil spill.

Regardless of their attempt, the spread of the oil to the surface and shore of the ocean was inevitable. Therefore, all marine animals were affected by the oil contamination in the Gulf of Mexico. Oil filled the blowholes and entered the lungs of dolphins and whales. This made breathing almost impossible.

Offshore oil drilling is a controversial topic because when oil spills, it does extensive amounts of damage to the environment. Countries capable of mining oil in the ocean reap the economic benefits in addition to reducing their dependency on external oil. While it is uncontroversial that offshore drilling is a massive boon for those countries, the environmental consequences of a spill also affect the economic welfare of nearby residents. Oil contaminates animals through a process called biomagnification, where chemicals progressively become more detrimental to the animals the higher they are on the food chain. When oil spills into the ocean, it impairs the growth of native species and deteriorates the ecosystem. As a result, the livelihood of people in the tourist industry, fisherman, and shrimpers is crippled and may take decades to recover.

Until now, when the offshore oil rig Deepwater Horizon exploded in 2010 and dumped 4.9 million barrels of oil into Louisiana salt marshes, scientists had no idea which kinds of animals were most affected and what impact it had on the food chain. However, with a new study from a Coastal Waters Consortium team of researchers led by Rutgers University postdoctoral researcher, Michael McCann, has found out what animals and insects affected by the Deepwater Horizon explosion that should be given the top priority for conservation, protection and research. The researchers found that terns, gulls and wading birds were both sensitive to the oil and so deeply connected to other animals in the food chain as predator and prey that losing them would impact

oil spill happened five years ago and nearly 5 barrels of oil was spilt into the Gulf of Mexico. The oil spill was caused from an explosion through the Deepwater Horizon drilling rig about 40 miles off the coast of Louisiana. The main effect from this oil spill was the losses of the animals. Causing many to almost go extinct. As a result from the oil spill the earth has had—losses from pollution, the cost, and the damage of people.

IMPACT OF THE DEEPWATER HORIZON OIL SPILL IN THE GULF OF MEXICO ON THE LOCAL ENVIRONMENT

Colwell, R. R. 2014. "Understanding The Effects Of The Deepwater Horizon Oil Spill". Bioscience 64 (9): 755-755. doi:10.1093/biosci/biu145.

USDC (2012) reports that on April 20, 2010 examinations of the world concentrated on an oil platform in the Gulf, around 50 miles off the Louisiana coastline. The mobile drilling unit Deepwater Horizon, which was being made used to drill an experimental well for BP Exploration and Production, Inc. (BP), violently blew up, ignited and at some point sank, tragically eliminating 11 employees. However that was just the start of the catastrophe. Oil and various other compounds from the rig and the well started streaming unabated around one mile below the area. Preliminary efforts to cap the wells were not successful, and for 87 days oil ejected unmonitored and uncontrolled into the Gulf. Oil soon enough covered a huge location of hundreds of square miles, and held by the tides and currents reached the coastline, contaminating beaches, bays, estuaries and marshes from the Florida panhandle to west of the Mississippi River delta. At the height of the spill, around 37 % of the open water in the Gulf was closed to fishing.

In Santa Barbara, California, in 1969, even though the spilled oil was not even very large, thousands of dolphins, seals, and birds were killed (Ivanovich, and Hays, 2008). Moreover, in the Gulf of Mexico, 82,000 birds, roughly 6,165 sea turtles, approximately 25,900 marine mammals, and indefinite amount of oysters, fishes, corals, and crabs have been harmed or killed by the spilled oil. Additionally, the spilled has killed many aquatic plants. ( A Center for Biological Diversity Report, 2008). As a result, vegetation, which are the most essential part of the ecological pyramid, and other animals will be affected negatively by the dangerous impact of the spilled oil, which probably is going to cause some problems in the ecological pyramid. In fact, any defect in the ecological pyramid may become a dreadful problem that occurs an ecological

The e Deepwater Horizon oil spill at the Macondo well began on April 20, 2010, in the Gulf of Mexico on the BP-operated Macondo Prospect. An explosion on the Deepwater Horizon drilling rig on 20 April 2010 killed 11 people and caused almost 5 million barrels of oil to flow into the Gulf of Mexico. The spill covered 68,000 square miles of land and sea and triggered a response effort involving the use of nearly 2 million gallons of dispersant chemicals (Pallardy). Considered the largest accidental marine oil spill in history, the Deepwater Horizon oil spill (DHOS) resulted in widespread environmental and economic damage, the exact nature of which is only beginning to be understood (Shultz 59). This paper will address the causes of this unmitigated ecological disaster and discuss steps that need to be taken to prevent a similar disaster from occurring again.

The oil also has a physical and physiological effect including irritation, inflammation, or necrosis of the skin, chemical burns, ingestion of oil/dispersants can lead to inflammation, ulcers, bleeding, as well as possible damage to liver, kidneys, and brain tissue. It can also cause disfunction of the immune and reproductive system. The wildlife can become physiologically stressed, their physical condition will ultimately decline, and some may even die. The oil spill has additionally had an extensive effect on the ecosystem as a whole. An ecosystem can be defined as a biological environment consisting of all the organism living in a particular area, as well as the non-living physical components of the environment with which the organisms interact. Experts predict that the ecosystem could require years or even decades to fully recover since there is a chance of biomagnification. Biomagnification occurs once a PBT(Persistent Bioaccumalative substances) have piled up in one part of the ecosystem the substance becomes concentrated from one link in the food web to the next. It can affect entire populations and threaten biodiversity in “insidious, sub-lethal” ways. In addition to the possibility of biomagnification the oil causes

The BP Oil Spill An Introductory Background - One of the most controversial ecological disasters in recent history focused on multinational British Petroleum and their Gulf of Mexico Operations. The Deepwater Oil Disaster began on April 20, 2010 with an explosion on the Deepwater Horizon Oil platform, killing 11, injuring 17. It was not until July 15th, however, that the leak was stopped by capping the wellhead, after releasing almost 5 million barrels (206 million gallons) of crude oil, or 53,000 barrels per day into the Gulf of Mexico. It was not until September 19th that the relief well process was complete and the U.S. Government, EPA, and Coast Guard agencies declared the well breach effectively stopped (Cavnar, 2010).

Deepwater Horizon oil Spill: BP’s drilling platform in the Gulf of Mexico had an explosion in April 2010, causing the “largest oil spill catastrophe in the petroleum industry history”. It caused the death of 11 men and injury to several others. “More than 150,000 barrels of crude oil gushed into the sea, every day, for almost 5 months and up to 68,000 square miles of the Gulf 's surface were covered” (1).
