The plan was criticised for its expense and poor results. This plume formed because chemical dispersants, released into the water to break up the oil so it could wash awayallowed the oil to mix with seawater and stay suspended below the surface. The island is a sensitive nesting area for brown pelicans.

Others, there are millions, because we didn't fish them last year," Mobile Bay's Callaway says. This paragraph was edited after posting. A Brief History Published: Despite the uncertainty surrounding the size of the spill, figures place it several times [9] the size by volume of the Exxon Valdez oil spill.

For example, dead dolphins that washed ashore earlier this spring have been seized by the U. But not much time has passed since the spill, and it will take many more years of monitoring and research to understand what happened.

The company said its oil is all accounted for and only exists in two places: A massive scientific effort is ongoing to precisely quantify the environmental damage caused by the oil spill—whether measured in oily sediments or missing generations of sealife.

In fact, oil fouled 35 percent of the U. These transformative investments will support the expansion of existing industries, development of new industries, and increased workforce training in coastal rural communities.

These slicks can wreak havoc on coastal ecosystems and animals, so cleanup workers use dispersants —chemicals that break down the oil into smaller particles that mix with water more easily—to prevent them from forming.

Various risks were identified and evaluated, in particular that an increase in microbial activity might reduce subsea oxygen levels, threatening fish and other animals. Evidence from prior spills, such as the Exxon Valdez suggests further long-term effects.

And some oil sunk to the seafloor by gluing together falling particles in the water such as bacteria and phytoplankton to form marine snow. While this technique had worked in shallower water, it failed here when gas combined with cold water to form methane hydrate crystals that blocked the opening at the top of the dome.

It also creates the risk that another disaster could divert money from the Gulf restoration pipeline. As much as 20 percent of the spilled oil may have ended up on top of and in the seafloor, damaging deep sea corals and potentially damaging other ecosystems that are unseen at the surface.

The Spill The Oil's Spread Mark Dodd, a wildlife biologist from Georgia's Department of Natural Resources, surveying oiled sargassum seaweed in the Gulf of Mexico after the Deepwater Horizon oil spill.
