The spill has now reached the coast at the Mississippi River estuary.

So far attempts to cap the leak have been unsuccessful and the oil slick has grown to over 600 square miles. As of this evening the oil was beginning to show up at the mouth of the Mississippi river.

From Truthout - Here’s a selection of animals at risk in the open water, along the coasts and in the wetlands. [click thumbnails]
The Great Bluefin Tuna, prized for sushi and sashimi, is one of the species most in danger of slipping into extinction. Traveling down across the Atlantic seaboard, bluefin tuna spawn in the Gulf of Mexico between mid-April and mid-June.
Five of the world’s seven sea turtle species live, migrate and breed in the Gulf region. Kemp's Ridley is the world's most endangered species of sea turtle, and one of its two primary migration routes runs south of Mississippi. Loggerhead turtles, also endangered, feed in the warmwaters in the Gulf between May and October.
Shark species worldwide are in decline. The grassbeds south of the Chandeleur Islands are very close to the oil spill. These grasses are a known nursing area for a number of shark species, which are now beginning their spawning season in the Gulf. Whale sharks, the world’s largest fish, feed on plankton at the surface of the water and could also be affected.
4. Marine Mammals — Whales, Porpoises, DolphinsOil spills pose an immediate threat to marine mammals, which need to surface and breathe. Not only does the oil pose a threat, but also the nasty toxins that the oil kicks off into the air. A resident pod of sperm whales in the spill area could be at risk along with piggy sperm whales, porpoises and dolphins.
The state bird of Louisiana, the pelican nests on barrier islands and feeds near shore. Brown pelicans only came off the endangered species list last year, but they’ve had a rough time in past seasons with storms. Their reproductive rates are low. Breeding season just started, and with eggs incubating the oil could pose a significant threat.
The coastal waters around the very tip of Louisiana’s boot-shaped coast are home to some of the most productive oyster farms in the country. Oils and hydrocarbons are toxic to oysters. Unfortunately, hydrocarbons can persist in coastal sediments for months or even years. Louisiana oyster farmers, many of whom barely scrape by with high fuel costs and global competition, could have trouble weathering the oil spill if their harvests are affected.
Coastal marshes are key to the life cycle and development of Louisiana shrimp and blue crab — both staples of the local seafood industry. Inshore shrimp season will open in mid-May, while brown shrimp are in their post-larval and juvenile development stages.
The young offspring of species such as mullet, menhaden and marsh-dwelling forage fishes are especially vulnerable at this time of year. Menhaden is a little fish you've probably never heard of, but people all over the world use it everyday. Menhaden fish oil and meat are used in everything from cosmetics to animal feed. Louisiana is one of the world’s biggest suppliers and the oil spill comes smack in the middle of menhaden spawning season.
Overdeveloped beachfronts all along the Gulf Coast from Texas to Florida have made life difficult for several species of plovers, sandpipers, terns and oystercatchers. Those that build their nests on the ground and feed on invertebrates are susceptible to oil on the beaches. Some migratory shore birds fly nearly the length of the Western Hemisphere and use barrier islands in the Gulf for key resting and refueling spots on their journey.
About 96 species of neotropical songbirds make a 500-mile journey without a pit stop across the Gulf of Mexico. The next two weeks mark the height of their migration as they travel north from Central and South America to breed in North America. The smoke from controlled burns to mitigate the oil spill could affect the migration, but the impacts will be difficult to monitor.
Containment booms deployed off the Louisiana coast in an attempt to contain the spill.
As that last link shows there is little consensus as to the actual amount of oil spilled and the rate at which it is spilling. Rates seem to vary from around 200,000 gallons per day as judged by the Coast Guard to over 800,000 gallons per day as calculated by a satellite data specialist. (See link at "7 million gallons")
Choppy water hampers efforts to stop the spill from passing the railroad trestle at Bay St. Louis, Miss.
Streams of oil in the open ocean head towards shore.
Attempts to harness the spill in the open ocean seem futile.

BP’s Greenwashing Masked Dangerous ‘Drill, Baby, Drill’ Reality
BP using toxic chemicals to ‘disperse’ spilled oil:
Right now there is a headlong rush to get this oil out of sight out of mind,” Charter said. “You can throw every resource we have at this spill. You can call out the Marine Corps and the National Guard. This is so big that it is unlikely that any amount of response is going to make much of a dent in the impacts. It’s going to be mostly watching it happen.

The White House is eager to avoid the mistakes made by President George W. Bush, who was seen as too detached from floundering rescue efforts after the much more dire Hurricane Katrina. And that is the problem for Obama right now: Things are not going well in the battle to contain the oil spill.Problems with big oil that won't go away
The Secretary of Defense has approved a request for two C-130 aircraft with Modular Aerial Spray Systems (MASS), which are currently en route to the affected area. The Coast Guard has requested assistance from the Department of Defense for these aircraft.Setting aside the issue of the toxicity of the chemicals being used, let's examine this.
These aircraft dispense the same dispersant chemical being used by BP and the federal responders. Each system is capable of covering up to 250 acres per flight with three flights per aircraft per day.
2 aircraft x 3 flights x 250 acres = 1,500 acres per day.
1 square mile = 640 acres.
Last figure I can find for the size of the spill: 600 square miles.
600 x 640 = 384,000 / 1,500 = 256 days.
The 600 square mile figure was after 1 week of leaking.
256 / 7 = 36.6 x 2 = 73.2 = the number of aircraft required just to keep up with the leak.
It gets worse - Interior Secretary Salazar: US Gulf Oil Spill May Be Worse Than Valdez:
Friday, industry experts said based on satellite images and standard measuring indexes, they estimate the spill rate at 20,000 barrels a day to 25,000 barrels a day. If those rates are accurate, the spill could already rival the 11-million gallon Valdez slick that economically and environmentally devastated part of Alaska.Shannyn Moore interviews Greg Palast on the oil spill:
.......
Salazar said that he believed BP could stop the leak, but he fears that it may take 90 days to do that. BP is placing a new rig over the leak and will soon attempt to use drilling tools to close the leak.
If the 25,000 barrel-a-day estimate is accurate and the leak lasts for 90 days, that's 2.25 million barrels, or 94.5 million gallons.
