A patch of oil has been documented about a quarter-mile northeast of the Macondo wellhead leased by BP. The company has provided a live feed of the Gulf well to officials, who could not see leakage.
Signs of recovery from the Gulf oil spill are already appearing, but scientists caution that many unknowns exist – including the effect of millions of gallons of oil dispersants.
Despite BP's efforts, only a small percentage of the oil from the Gulf of Mexico oil spill will be cleaned up, say experts.
The oil spill that resulted from the explosion and sinking of an oil rig in the Gulf of Mexico last week is becoming more worrying as it continues to spread and efforts at stemming the flow of the leaking oil are being met with difficulties.
