“What quiet, what silence, what peace!” Captain Nemo  That was 1870. Today — to the dismay of whale lovers and friends of marine mammals, if not divers and submarine captains — the ocean depths have become a noisy place. The causes are human: the sonar blasts of military exercises, the booms from air guns used in oil and gas exploration, and the whine from fleets of commercial ships that relentlessly crisscross the global seas. Nature has its own undersea noises. But the new ones are loud and ubiquitous. http://www.nytimes.com/2012/12/11/science/project-seeks-to-map-and-reduce-ocean-noise-pollution.html?ref=science
