I found this article interesting could new sonar systems be responsible for some of the mass beachings and if so will the powers that be take it in
account? Here is the info I open the floor.
The first detailed study of the effects of naval sonar on whales shows that whales flee from prime feeding sites when navy tests begin – leaving
them famished when they finally return.
Blainville's beaked whales, Mesoplodon densirostris, use echolocation clicks to track down prey in the lightless depths they hunt in, a kilometre or
more below the surface.
To find out whether the whales are disturbed by naval sonar operations, Peter Tyack of Woods Hole Oceanographic Institution, Massachusetts, and
colleagues tracked the activity of Blainville's beaked whales during exercises at a US navy centre near Andros Island, Bahamas. The area encompasses
an underwater canyon that is a prime hunting ground for these deep-diving whales.
The credentials: Peter Tyack: www.whoi.edu...
The Field study data:
If whales and other echolocation mammals are effected in such a manner, Is it possible that eventually miles of patrolled coast line may become
vacant, feeding grounds completely abandoned due to naval activity of any nation?
What effect will this have on the fishing industry, a possible chain reaction as natural predators are chased out of their hunting grounds only to
have the prey impact other life in the area. There really isn't a lot to be done the Navy will certainly not change their sonar format, and mammals
cant exactly bang on the tub with a broom handle reciting the whale version of "Hey Keep it down up there!" So how should future technologies be
adapted to take into account our effect on the local environment, is there even a way to do so. Thanks for reading and please let's keep it
