Seismic airguns shoot extremely loud and repeated blasts of sound, each 100,000 times more intense than what one would experience if standing near a jet engine. The dynamite-like blasts occur every ten seconds, for days to weeks at a time. ecowatch.com

The purpose of these blasts is to look for oil and gas deposits deep under the ocean floor. They are so loud they they disturb, injure and kill marine life. Proposed blasting by the US government in an area twice the size of California, from Delaware to Florida, is expected to injure and kill large numbers of dolphins and whales along the East Coast and disturb the necessary activities of millions more. The North Atlantic Right Whale is at particular risk, a species of large whale that is critically endangered.

The impacts of seismic blasting can include hearing loss, loss of habitat, disruption to mating and feeding and can cause strandings and death.
