What oil tanker created a major water problem around Alaska?
The Exxon Valdez.
How does the GULf of Mexico and the Exxon Valdez oil spill differ?
Many differences: 1) Exxon Valdez was a tanker accident, therefore the quantity of oil was known. The spill size in the Gulf of Mexico is unknown as oil is still spilling from the wellbore. 2) Wave action was probably more effective in breaking up the oil spill. 3) Oil booms were not available to contain the Exxon-Valdez spill. 4) Other measures to disperse the spill were not available. Surfactants and bio-remediation were used late in the clean up operation. 5) The Exxon Valdez appears to be a more viscous oil than the Gulf spill. No attempt to burn the oil was considered. The Exxon oil was more prone to form emulsions. 6) Due to water temperatures, the Exxon oil was unlikely to evaporate th high end alkanes. In the Gulf spill (and also the Kuwait spill) high temperatures will allow the high end alkanes to evaporate.
What thing they try in order to stop the Exxon Valdez oil spill?
They really didn't try any certain thing, but a number of methods, such as washing beaches and rocks with high pressured hot water, until it was found out to be more harmful then helpful. They also used boom and high pressured cold water instead of hot water, and a few chemical agents were used to try to break up the oil. They took the remaining oil on the Exxon Valdez ship out so no more would leak into Prince William Sound.
What is the difference in the crude oil in the gulf of Mexico and oil spill from exxon-valdez?
The main difference is the type of leak. The Exxon-Valdez spill was oil leaking from a tanker after an accident. The BP Gulf of Mexico oil spill is oil leaking from underwater at a greater depth.As a result, the oil reacts differently because of:Pressure 3 miles below sea waterThe speed at which the oil is gushing out, (as opposed to just leaking out)The reduced air in the water at that pressure.This leads to different forms of emulsification and other reactions of the oil and water, which can lead to a more complicated damage and clean-up.
Is it true that the blown-out oil well in the Gulf of Mexico is a bigger and worse leak than the Exxon Valdez disaster?
Sometimes, simple questions do not lead to simple answers. More oil spilled- Yes. Areally larger - difficult to say. Worse to the environment- too early to tell. Environmental damage is complicated. While I hate to complicate good headlines with minor technical details, but let me suggest that comparing Exxon Valdez to BP spill is difficult. Different marine and coastal environments, different type of spill, different clean up containment and clean up measures. Any oil spill will expand with the wind and currents, and undergo mechanical dispersion, with chemical and biological changes to its structure and makeup. Assessment of the environmental impacts of the weathered oil, distant from the foci can be subjective. Has more oil spilled out into the Gulf of Mexico at this point in time than spilled during the Exxon- Valdez disaster? The best answer is yes, if you accept the Task Force estimated Macondo flow rates of 12,000 to 19,000 barrels/day or 0.504 to 0.798 million gallons per day. Perhaps you've seen the headline that more than a million gallons is flowing from the well. It is actually a bit less than a million gallons per day on the upper end of the range. So, given the well has been flowing for around 40 days, the oil spilled in the gulf to present (May 30) is approximately 20 to 32 million gallons. Exxon valdez accident in 1989 spilled 11 million gallons. The volume issue is complicated by the fact that oil is being recovered with skimmers, which will continue after the well has been capped. The insertion tube and control burns reduce the amount of oil at surface. The volume at the surface is being diminished everyday by evaporation of the lighter hydrocarbons and dissolving in the sea water aided by dispersants. Evaporation did occur with Exxon-Valdez oil, but it was a heavier crude and seawater was colder. So is the net oil volume at the surface for the BP spill more than Exxon Valdez? I don't have an answer. Is the areal extent larger? I know for the Exxon-Valdez spill, the affected area became a very controversial issue- particularly in the courts. I expect that the areal extent of the BP spill will be equally controversial, as it becomes more difficult to track the individual streams with low concentrations of oil (or tar balls). Which spill has done the most environmental damage? I think it's too early to tell. Oil has invaded environmentally sensitive areas but at present, it is fairly localized. The BP spill is still going as of May 30. There will be some recovery of the ecosystem, as was the case in the Gulf War spill, Ixtoc, and the Exxon Valdez. See related links.
Where did the Exxon Valdez environmental disaster occur?
Alaska in Prince William Sound. The oil is still in the environment and will be for another 100 years. It ruined a pristine environment and killed many animals. If you would like to see what it did you can find it online and get a first hand view of that happened as the oil came ashore and mixed with the cold water.
