The Trump administration has given the go-ahead for a series of seismic surveys to look for oil off the Eastern Seaboard, a move that has already sparked criticism.
Environmental advocates have criticized the surveys for the effect those sounds can have on marine life. Studies have found they can be deafening to whales, dolphins, and other marine animals with acute senses of hearing.
They're also typically a first step toward offshore oil drilling. A number of politicians, including several Republican governors on the affected coast have opposed offshore oil drilling in recent years.
In addition to the bipartisan political opposition to the surveys, they could also face legal challenges aimed at delaying or stopping them altogether.
