Results from a study using acoustic technology to determine the amount of oil and natural gas released by the Deepwater Horizon spill matched the federal government’s estimates, validating the new measuring technique, researchers said.
The study concluded that oil spewed from the Macondo well into the Gulf of Mexico at a rate of about 57,000 barrels a day, for a total of almost 5 million barrels between April 20 and July 15, 2010, when the well was capped.
In May 2010, a team from the Woods Hole Oceanographic Institution installed two acoustic instruments on a remotely operated vehicle. A Doppler profiler measured shifts in sound and an imaging multi-beam sonar distinguished oil and gas from sea water. The Doppler produced 85,000 measurements, and the sonar produced 2,500 images.
