i'm interested in any evidence or otherwise for sonar effects upon
mammals such as whales and dolphins. is there any hard evidence?

Would recomend you check sources of vlf and ulf if you have not
already.
I have heard of incidents of disorientation ?(surfacing too quickly
when deep diving) probably caused by "rapid" sonar pings.
Cant give you any references just now, will check on Monday.

No "smoking gun", AFAIK, but news reports do suggest that the USN has
internally accepted that their sonar probably is killing marine life.
Actually, this is just common sense, given that modern sonar can put out
sound at 235 decibels. (That is not a typo!)
In a recent incident in Puget Sound, humans standing on shore 10 miles
away from the USS Shoup (DDG-86), an Arleigh Burke class destroyer based
in Everett, WA, (a sister ship of the ill-fated USS Cole), could plainly
hear the unpleasant screeching of the ship's sonar, which had apparently
been left on by some misunderstanding. (USN regulations allegedly forbid
use of sonar under ordinary operating conditions within 100 miles of
shore, which may give some idea of the power of the sound and also of the
Navy's concern about public perception.) At the same time, a pod of orcas
was observed behaving in an unusual way (bunching together, breaching,
general appearance of distress, then apparently trying to escape from the
sound by hiding in a small inlet). Soon thereafter a number of dead
porpoises were washed up in the area, but apparently autopsies were
inconclusive due to decomposition.

I am not sure what this topic has to do with physics, though, so I set
followups to a possibly more suitable newsgroup.
