Seismic airgun blasting is used to detect oil and gas deposits on the seafloor. Seismic airguns are towed behind ships, and blast every ten seconds, 24 hours a day, for days and weeks at a time. (photo – en.paperblog.com)
Blasts can be heard 2,500 Miles from the source!
The noise of this industrial-sized seismic airgun blasting is so loud that it can be heard up to 2,500 miles from the source, creating what biologists call an “acoustic smog” that drowns out whale chatter and interferes with the way marine mammals perceive the world. Over time, animals that rely on sonar and listening to ‘see’ can go blind and can’t function properly.
For animals like whales and dolphins that use sound to eat, hunt, find mates, navigate and communicate with their young families, these sonic booms could be a death sentence. (photo – oceania)
138,000 Whales and Dolphins could be injured!
According to government estimates, seismic airgun testing currently being proposed in the Atlantic could injure 138,000 whales and dolphins, harm commercial fisheries, and disrupt coastal economies. Airgun blasts can also kill fish eggs and larvae and scare away fish from important habitats. Following seismic surveys catch rates of cod and haddock declined by 40 to 80 percent for thousands of miles.
Seismic Blasting poses and Unacceptable Risk to Marine Life!
Two years ago, a group of 75 marine scientists, including leading biologists and bioacousticians from Cornell, Duke, and Stanford, warned that opening the east coast to seismic airgun blasting is likely to have “significant, long-lasting and widespread impacts on the reproduction and survival of fish and marine mammal populations in the region, including the critically endangered North Atlantic right whale, of which only 500 remain.” They warned that it “poses an unacceptable risk of serious harm to marine life.”
Obama denied permits for blasting in the Atlantic!
On January 6, the Obama administration formally denied all pending permits to conduct seismic airgun blasting in the Atlantic Ocean in an area twice the size of California, stretching from Delaware to Florida. On May 10, the Trump administration announced it is moving forward on seismic surveys in the Atlantic Ocean, the first step toward offshore drilling in a region where drilling has been blocked for decades.
The Trump Administration “streamlines” seismic blasting!
As part of his plan for “energy dominance” Trump directed two federal agencies, the Interior Department and the Commerce Department (specifically NOAA – the National Oceanic and Admospheric Administration), to “streamline” permitting for seismic blasting under existing law. To prepare the way for seismic collateral damage, the current administration had NOAA issue draft Incidental Harassment Authorizations (IHAs) for public comment that ends July 6, 2017. If approved, these IHA’s give geophysical companies permission to harm or disturb marine life in the pursuit of offshore oil. (photo – 15minutenews.com)
