Hi Gary,

       Look for ocean / storm related noise and also noise assocoiated with 
weather fronts.
       Ocean microiseisms tend to be in the 4 to 8 second region, but you may 
get wave noise nerare 10 to 12 seconds. Weather noise is often broadband.

       Have you got the damping set correctly? This can also cause noise 
peaks if it is too low.

       Regards,

       Chris Chapman
