On April 20th, an explosion on the Deepwater Horizon, a semi-submersible drilling rig, left 17 workers injured and 11 missing and presumed dead. Oil is spilling from a well 5000 feet below sea level, discharging 200,000 gallons of crude oil a day according to the official estimate (though over 2 million a day, by private estimates).
The spill covers at least 2500 square miles of ocean surface. But how big is the spill, really? It's hard to get a sense of the true size when it's over the ocean floor. Compare the size of the oil spill to your own city.
