Air Gun Testing

That's the sound of air gun testing for the [presence:stress] of oil and gas under the seabed. " Air gun" is a euphemism for a massive release of [compressed:expressed] air. Don't like it? Neither does underwater life. Such testing also isn't a one-off [burst:flare] of 250-decibel sound louder than a jet engine. For days or even weeks at a time, these guns send a volley of ear-shattering sound through the ocean to impact the seafloor every ten seconds or so. That's nearly 9,000 such [bursts:thirsts] per day. Our [mammal:nano] cousins, whales, and dolphins particularly loathe the air guns.
