STRANDED - The Ocean is a World of Sound

Lethal Sounds
The use of military sonar poses a deadly threat to whales and other marine mammals

Mass beachings occur in many species, mostly beaked whales that use echolocation for deep diving. The frequency and size of beachings around the world, recorded over the last 1,000 years in religious tracts and more recently in scientific surveys, have been used to estimate the population of various whale species by assuming that the proportion of the total whale population beaching in any one year is constant. Beached whales can give other clues about population conditions, especially health problems. For example, bleeding around ears, internal lesions, and nitrogen bubbles in organ tissue suggest DECOMPRESSION SICKNESS.

(the problem is that they are shocked by the sounds and dive up in panic way too quickly from the deep to escape somehow- this leads to "decompression sickness" and you cant "save" them by pushing them back into the water as they show on tv...)

This is one of the most horrific things I have ever seen, and the british navy has just had an undocking ceremony for their largest sub yet, the 291-foot long HMS Ambush.

"Its advanced radar and sonar equipment allow the craft to spot enemy vessels at a distance of up to 3,000 nautical miles, meaning the submarine could comfortably screen the U.S. East Coast while diving in Scottish waters, the Daily Mail newspaper writes."
