Impact Of Ecosystem On The Deepwater Horizon

Deepwater Horizon oil spill's dramatic effect on stingrays' sensory abilities Study first to measure physiological effects of crude oil on marine animals' olfactory system Peer-Reviewed Publication Florida Atlantic University image: Marine fishes, like stingrays, rely on the effective functioning of their sensory systems to survive.

Exposure to crude oil could detrimentally impact their fitness, lead to premature death, and cause additional cascading effects through lower trophic levels. Kajiura, Ph. Described as the worst environmental disaster in the United States, nearly 5 million barrels of crude oil oozed into the Gulf of Mexico, severely degrading the marine ecosystem immediately surrounding the spill site and directly impacting coastal habitats along 1, kilometers of shoreline.

About 10 million gallons remain in the sediment at the bottom of the Gulf and may continue to cause severe physiological damages to marine life, including impairment of sensory systems. Marine fishes rely on the effective functioning of their sensory systems to survive. Despite the obvious importance of their olfactory sense of smell system, the impact of crude oil exposure on sensory function remains largely unexplored.

Researchers at Florida Atlantic University are the first to quantify the physiological effects of whole crude oil on the olfactory function of a marine vertebrate - the Atlantic stingray, Hypanus sabinus, an elasmobranch fish. Results of the study, published in Scientific Reports, confirm that exposure to crude oil, at concentrations mimicking those measured in coastal areas following the Deepwater Horizon oil spill, significantly impaired olfactory function in the Atlantic stingray after just 48 hours of exposure.

These findings suggest that exposure to crude oil could detrimentally impact fitness, lead to premature death, and cause additional cascading effects through lower trophic levels. Any impairment of these sensory systems could have a damaging effect on their survival and fitness," said Stephen M. The work was conducted by Eloise J. Cave, as part of her master's degree in Kajiura's lab. Cave, who is now a Ph. She found the oil exposed animals exhibited a smaller response, with a slower onset and longer duration. The researchers caution that deep-sea benthic species like skates - a type of cartilaginous fish that develop for prolonged periods in egg cases on the seafloor - in particular, could be continuously exposed to high concentrations of crude oil in the sediment throughout sensitive developmental periods.]

Dose-response relationships with expected oil concentrations were utilized to estimate the impact on fish growth and mortality rates. We also examine the effects of fisheries closures and impacts on recruitment. We validate predictions of the model by comparing population trends and age structure before and after the oil spill with fisheries independent data. The model suggests that recruitment effects and fishery closures had little influence on biomass dynamics. However, at the assumed level of oil concentrations and toxicity, impacts on fish mortality and growth rates were large and commensurate with observations. Impacts on reef and demersal forage caused starvation mortality in predators and increased reliance on pelagic forage. Impacts on the food web translated effects of the spill far away from the oiled area. Impact Of Ecosystem On The Deepwater Horizon.

Impact Of Ecosystem On The Deepwater Horizon - something

Deepwater Horizon Oil Spill. Extracts from this document Introduction Introduction The Deepwater Horizon Oil Spill was a man-made disaster which had devastating effects on its surrounding environment, in particular the natural environment around the Deepwater Horizon Oil Rig. Recovery efforts made by the local governments utilized Information Communications Technology ICT such as remote sensors and satellite imagery to track and monitor the magnitude of the oil spill. Further detail on how recovery efforts used ICT's to track and monitor the oil spill as well as its uses in the prevention of future oil spills, including the positives and negatives of the use of ICT will be discussed. The focus reading 'Organisations Aiming to Reduce Risk - Worth Broader Exposure' will be used as a comparison and reference to what other industries have done to prevent disasters in their industry from occurring again. Middle The oil production industry using satellites similarly to how they were used in the in recovery efforts through, obtaining a wide view of the area through SAR satellite imagery and using high-resolution imagery in order to gain a detailed perspective of specific locations and aspects of oil rigs. The National Commission recommended improvements be made by the petroleum production industry as well as the national government in order to effectively plan for a large scale containment plan if another event like this we're to happen again, including coordinating with other government bodies and obtaining relevant information in regards to response measures. Measures taken into account include things like and sufficient amount of technical experts on the within the staff of the oil rigs in order to develop and approve response plans as well as providing mandatory funding to the petroleum production industry for research and development as well as incentives to the industry to perform research and development.
