On Friday, the Obama administration gave approval for a massive seismic testing program aimed at detecting oil and gas reserves in the Atlantic ocean and updating its geological surveys. The endeavor will employ deep-penetrating and high-resolution blasts of sound to survey the contours of the ocean floor in the search for offshore resources, sending sound waves into the deep and recording what they hear back.
The testing, which will occur 20 miles to 430 miles offshore from Delaware to Orlando, Florida, was called a "sonogram of the Earth," by Andy Radford, a petroleum engineer at the American Petroleum Institute, an oil and gas trade association in Washington, D.C. But in reality, the project is not so innocuous.
Ocean noise has been a huge problem for marine life for decades, especially sensitive marine mammals like whales and dolphins. In a newly-released book titled "War of the Whales," journalist Josh Horowitz detailed how the U.S. Navy's seismic testing programs have saturated the oceans with sound, leading to mass strandings that killed countless whales.
This new problem isn't so different -- in fact, the the U.S. Bureau of Ocean Energy Management (BOEM) has already acknowledged that thousands of sea creatures will be harmed. The sonic cannons that will be used, towed behind boats through the open ocean, are fired continuously for weeks or months. The sound can reach thousands of miles. BOEM's environmental impact study estimates that more than 138,000 sea creatures could be harmed, including nine of the world's remaining 500 north Atlantic right whales.
