New Guidelines Seek To Curb Risks to Whales From Seismic TestsSource: Rigzone | 22 January 2014
Safeguards on seismic testing for an oil and gas project in the Pacific have shielded endangered whales from harm and are a model for managing the deafening blasts, the world’s largest environmental group said on 20 January.
Conservationists working with Sakhalin Energy Investment in Russia from 2006–12 said the tiny population of endangered Western Grey whales had risen approximately 3% a year to 140, despite seismic testing near their feeding grounds.
Seismic testing bounces sound waves into the seabed to seek deposits of oil and gas. It can harm whales and other marine life with blasts of 230 to 250 decibels, so loud that they can sometimes be detected 4000 km away.
“This work helps to set a standard,” said Carl Gustaf Lundin, director of the global marine and polar program at the International Union for Conservation of Nature (IUCN). “Once you have raised the bar … other companies will look bad if they are not deploying it.”
The IUCN includes governments, scientists, and conservation organizations and is the world’s biggest environmental alliance.
