What are some strategies for reducing ship, sonar, and
seismic airgun array noise in the oceans in order to
reduce negative effects on marine mammals?
I have also posted this to sci.physics.acoustics and
other groups so you might want to check for replies
there as well if you are interested.

propellers.
Wooden ships and iron men? I don't think that'll work for oil
tankers.
Know about the Dyson fan AKA "air multiplier"? Rework its fluid
dynamics for water.
"Seismic airgun arrays" are going out of style in favor of passive
systems.
It's worth doing even ignoring benefits to wildlife because
turbulence is expensive.

You should ask the US navy. They have been in the noise

reduction business for decades. Maybe, however, most of
their work is still classified.
One result of the cold war game of silence has been a
propeller that reduces or eliminates cavitation at high
rotational speeds. Cavitation can produce some serious
noise.

I also just posted to sci.military.naval and other groups.

How about noise cancelling technology. Pass laws that say every ship

must carry an anti-noise source ?
