ST. AUGUSTINE BEACH, Fla. – The Obama administration is reopening the Eastern Seaboard to offshore oil and gas exploration, approving seismic surveys using sonic cannons that can pinpoint energy deposits deep beneath the ocean floor.
Friday’s announcement is the first real step toward what could be a transformation in coastal states, creating thousands of jobs to support a new energy infrastructure. But it dismayed environmentalists and people who owe their livelihoods to fisheries and tourism.
The cannons create noise pollution in waters shared by whales, dolphins and turtles, sending sound waves many times louder than a jet engine reverberating through the deep every 10 seconds for weeks at a time. Arguing that endangered species could be harmed was the environmental groups’ best hope for extending a decades-old ban against drilling off the U.S. Atlantic coast.
The U.S. Bureau of Ocean Energy Management acknowledged that thousands of sea creatures will be harmed even as it approved opening the outer continental shelf from Delaware to Florida to exploration. Energy companies need the data as they prepare to apply for drilling leases in 2018, when current congressional limits expire.
“The bureau’s decision reflects a carefully analyzed and balanced approach that will allow us to increase our understanding of potential offshore resources while protecting the human, marine, and coastal environments,” acting BOEM Director Walter Cruickshank said in a statement.
Sonic cannons are already used in the western Gulf of Mexico, off Alaska and in other offshore oil operations around the world. They are towed behind boats, sending down pulses of sound that reverberate beneath the sea floor and rebound to the surface. Hydrophones capture the results, which computers translate into high resolution, three-dimensional images.
“It’s like a sonogram of the Earth,” said Andy Radford, a petroleum engineer at the American Petroleum Institute, an oil and gas trade association in Washington, D.C. “You can’t see the oil and gas, but you can see the structures in the Earth that might hold oil and gas.”
The surveys also can map marine habitats and identify solid undersea flooring for wind energy turbines. But fossil fuel mostly funds this research, and corporations keep the data secret, disclosing it only to the government.
Oil lobbyists say drilling for the estimated 4.72 billion barrels of recoverable oil and 37.51 trillion cubic feet of natural gas that lies beneath federal waters from Florida to Maine could generate $195 billion in investment and spending from 2017 to 2035, contributing $23.5 billion per year to the economy.
These estimates describe the total amount of energy “technically recoverable” from the nation’s outer continental shelf, but the Atlantic seabed from New Jersey through New England remains off-limits for now. While some states have passed drilling bans, Virginia and the Carolinas asked for the surveys, bureau officials explained Friday.
“I honestly feel we can go offshore and harvest the energy that’s out there,” said South Carolina state Sen. Paul Campbell. “I think we’re kind of foolish not to.”
In any case, the area to be mapped is farther offshore in federal waters, beyond the reach of state law.
