Scientists warn Obama of marine life harm from seismic tests
Marine scientists are raising concerns about the Obama administration's decision to move ahead on use of seismic air guns in the Atlantic Ocean for oil and gas exploration.
Seventy-five scientists from around the globe on Thursday sent a letter to President Barack Obama saying the use of the guns, which create canonlike air blasts underwater, represents a "significant threat to marine life throughout the region."
The air blasts fire every 10-12 seconds for weeks or months at a time, which can harm marine mammals that rely on hearing to survive.
Nine permits are before the Bureau of Ocean Energy Management, which must also be approved by NOAA Fisheries before being finalized.
The government says no seismic applications will be approved without measures meant to mitigate harm to marine life.
