Section 1 - OPERATIONAL

1.1. Environmental Considerations

Seismic Sound Sources and Marine Life

Although not proven, there is concern in some quarters that marine mammals may be
harmed or their behaviour changed by seismic activity. The sound pulses from sparkers
and boomers is much lower in amplitude and higher in frequency (so it will travel less
far) than air guns. However it makes sense that a precautionary approach to emitting

sounds in the whales and dolphins’ natural habitat should be observed.

The CSP energy sources described in this manual have the ability to “soft

-

start” and

increase the energy emitted in the water slowly over time and this technique will give
any  marine  mammals  nearby  the  opportunity  to  escape  before  maximum  signal
amplitude is reached. It will also give them a chance to get used to the noise if they
choose  to  stay  (!)  rather  than  being  subjected  to  a  sudden  shock  of  a  full  power
seismic signal.

The procedure is quite simple:-

By using a slow repetition rate

–

say at 1 pulse per 15 seconds and by using the “Auto”

charge rate, the energy will slowly increase over the course of several minutes. Once full
power  has  been  achieved,  the  repetition  rate  can  then  be  slowly  increased  until  the
rate desired for the survey has been achieved.

Another factor to consider is to ensure that the start of any survey line is not in such a
location  that  any  cetacean  is  trapped  by  the  vessel  and  the  noise,  for  example  in  a
small  harbour.  In  such  an  instance,  the  survey  should  start  in  such  a  place  that  any
cetacean in the vicinity has a clear and rapid means of escape into open water and
away  from  any  unnatural  noise  source.  Further  details  and  advice  can  be  obtained
from

the

following

web

site:-

http://www.jncc.gov.uk/pdf/Seismic_survey_guidelines_200404.pdf. This web site
refers to UK waters and relates to air guns as the sound source (in many ways different
to a sparker or boomer), but should serve as a useful guide nonetheless.
