US scientists announced on Wednesday that nearly 75 percent of the oil from the BP spill in the Gulf of Mexico has disappeared. According to the report "BP Deepwater Horizon Oil Budget: What Happened to the Oil?", 25 percent was removed through burning, skimming, and direct recovery from the wellhead. Another 25 percent evaporated or dissolved naturally, while 24 percent was dispersed into small droplets. The remaining oil is either on or just below the water's surface, washed ashore, or buried in sand and sediments at the sea bottom. Unified Command, which consists of government and private efforts, has addressed 33 percent of the spilled oil. The report discovered that 17 percent of the oil was collected directly from the wellhead, while 5 percent was burned, 3 percent was skimmed, and 8 percent was dispersed using chemicals. The remaining 74 percent was removed through natural processes. Carol Browner, energy and climate change adviser to President Barack Obama, expressed optimism on ABC's "Good Morning America" show, stating that the majority of the oil seems to have disappeared according to initial assessments by scientists. She also emphasized that this development is seen as a significant milestone.
