I did this quite a long time ago with contact microphones buried a
tiny bit
below the surface of a grassy field in the summer afternoon sun.
There were
a lot of insect sounds, and the sound of the grass being blown by
the wind.
This was such a long time ago, that I only had a Marantz cassette
recorder
at the time. I can only speculate how much better the digital sound
would
be, as well as with better contact microphones (after soldering, I
coat them
with Plasti Dip, a rubber coating used mostly for hand tools, found at
hardware stores). I had a lot of problems with grounding (go
figure), but
found the best solution was to use battery power instead of electric
from a
battery eliminator. The best thing to do is to just
experiment...although
depending on where you are, most of the bugs are now going to sleep.
Best,
John
PS. as always, if you had access to scientific recording devices,
you could
probably get the sounds of worms, earth tremors, etc. but these
kinds of
devices are mostly hanging around university labs, and used for
purposes
other than recording nature...of course, if you hang around
university labs,
then you are set. Geological labs are probably the best.

I'm a little unsure of how to go about this and I can't seem to
find much
information on it.
Any help or ideas would be great!
