[Coral-List] Effects of seismic airguns on Acropora

I am working on a project where I am required to assess the potential
effects of seismic airguns on several marine species, including coral -
specifically Acropora palmata and A. cervicornis. So far I have found
only limited information addressing the effects of seismic airgun
surveys on corals. I'm interested in whether airgun pulses have the
potential to affect Acropora. If so, is information available
indicating at what sound levels those effects would be expected?
Also, can anyone point me to similar information on the effects to coral
from other types of underwater pulsed sound? For example, use of
underwater explosives - although seismic airgun pulses would have slower
rise times and be less energetic, data on other types of pulsed sound
and effects on coral would be informative.
