HOUSTON/PORT FOURCHON, Louisiana (Reuters) - BP on Thursday geared up for its latest attempt to control a gushing undersea well as environmentalists complained they were being kept in the dark about the oil spill's potential ecological impact.
BP Plc, the British energy giant, said it would deploy a small containment dome, known as a "top hat," soon to trap the oil at the site of the leak a mile beneath the Gulf of Mexico.
