You can download a little application that will allow you, via Google Earth, to overlay the Deepwater Horizon oil spill onto the city of your choice. If that seems like too much work, you can just see some of the results. How does the spill compare to Tokyo? San Francisco? Washington, DC? Duluth?

Oil spill in the Gulf of Mexico: NASA's Aqua satellite captured this image of the Gulf of Mexico on April 25, 2010 using its Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. With the Mississippi Delta on the left, the silvery swirling oil slick from the April 20 explosion and subsequent sinking of the Deepwater Horizon drilling platform is highly visible. The rig was located roughly 50 miles southeast of the coast of Louisiana.

CNN's got a spill tracker - watch the slick spread. (You can also view satellite images of the oil spill and see a discussion of just how much oil we're talking about.)

BP is set to try out a never-before-used technique to capture some of the 210,000 gallons of oil spilling each day from a damaged well in the Gulf of Mexico. They've built a 4-story "containment dome," and are set to lower it over the punctured riser pipe. If the plan works, oil spewing from the well will collect inside the dome, where ships on the surface can pump it out.

Other crews are burning oil on the water's surface, or collecting it with giant skimmers. And remote operated vehicles near the ocean floor are trying to close valves on the broken wellhead.

A more permanent solution is to drill a relief well next to the damaged one, but that will take a few months.

Here's a video that offers a pretty straightforward explanation of how the oil spill in the Gulf of Mexico happened, why it has been so difficult to deal with, and some of the plans that have been proposed to take care of it.

All your official oil spill info in one place

One website, DeepWaterHorizonResponse.com, combines information from multiple official sources.

Social media techniques are being applied in response to the 2010 BP oil spill disaster. The site is being maintained by British Petroleum, Transocean, the U.S. Coast Guard, the National Atmospheric and Oceanic Administration, the U.S. Department of Homeland Security, and the U.S. Department of Interior.

Excellent resource for learning about oil spills

Front and center is a Flickr slideshow hosted by U.S. Coast Guard Eighth District External Affairs. In the right column is a list of "latest information" links to news items and also PDFs and Word documents describing dispersants, booms and skimmers, and many "how to ..." tasks like reporting oil soaked wildlife or submitting claims for damages.

I wish to thank ReadWriteWeb for pointing me toward this site.

The site allows you to register for updates. It also provides numbers to call for oiled wildlife, to report oil spill related damage, to report oiled shoreline, to request volunteer information or to submit alternative response technology, services or products.

Chemicals known as dispersants are now being used against the ever increasing amount of oil leaking out of a deep water well head. Dispersants help break the larger masses of oil into smaller droplets which will mix into the water. These dispersants are being sprayed onto the surface slicks and are also being injected directly into the oil flowing out almost a mile under the surface.

Officials said that in two tests, that method appeared to be keeping crude oil from rising to the surface. They said that the procedure could be used more frequently once evaluations of its impact on the deepwater ecology were completed. New York Times

How do chemicals disperse the oil?

Dispersant chemicals contain solvents to assist it in dissolving into and throughout the oil mass and a surfactant which acts like soap. Surfactant molecules have one end that sticks to water and one end that sticks to oil. This, along with wave action, breaks masses of oil into droplets small enough that they stay suspended under water, rather than floating back to the surface.

Are these chemicals safe?

Such cleanup products can only be used by public authorities responding to an emergency if they are individually listed on the National Contingency Plan Product Schedule.

Many of the first dispersants used in the 70s and 80s did show high toxicity to marine organisms. However, today there is a wealth of laboratory data indicating that modern dispersants and oil/dispersant mixtures exhibit relatively low toxicity to marine organisms.
On occasions the benefit gained by using dispersants to protect coastal amenities, sea birds and intertidal marine life may far outweigh disadvantages such as the potential for temporary tainting of fish stocks. ITOPF

Here is a link to one product on their list (Oil Gone Easy Marine S200

Hard choices

According to National Geographic News, "Dispersants only alter the destination of the toxic compounds in the oil." Moving the oil off the surface protects the birds and animals along the shoreline but will increase the oil exposure for fish, shrimp, corals, and oysters. I hate to mention what hurricanes will do to this situation.

Is deep water drilling worth the cost?

The costs of a "Drill, Baby, Drill" policy are being measured this week in lives, money, business income, and environmental damage.

BP (British Petroleum) says it is spending $6 million a day to battle a growing oil spill which resulted from a deep water oil rig accident. The oil rig, Deepwater Horizon, worth $560 million, was destroyed. Eleven missing workers are presumed dead. Crude oil continues to flow into the Gulf at about 5000 barrels (210,000 gallons) a day. Fishing and tourism businesses are fearful upon hearing that the oil spill is only a day away.

Ways to fight the 2010 Gulf oil spill

  • Stop the oil flow at the well head with remote-controlled submarines (unsuccessful so far)
  • Drop a dome over the leak and pipe oil to surface vessels (will take 2 to 4 weeks)
  • Drill relief wells to relieve pressure and plug up gushing cavity (will take months)
  • Burn the oil (oil quickly becomes too waterlogged to burn)
  • Stop the oil spill with floating booms and skim oil off surface
  • Use chemicals to make oil mix into the water
