Abstract
Research
surrounding
acoustic
resonance
properties
of
ice
has
increased
and
now
a
practical
method
for
depth
profiling
has been
developed.
Experiments
were
performed
in
real-time
with
high
sensitivity
,
biaxial
,
wide
bandwidth
accelerometers
(10
KHz
bandwidth)
,
which
encompassed
a
high
sampling
rate
of
200
Kb/sec/channel
with a
12-bit
resolution
(36
dB).
The
implementation
of
signal
processing
produced
a
seismic
and
resonant
signature.
Initially
repeated
results
revealed
an
accurate
correlation
between
ice
depth
to its
characteristic
frequency.
The
required
velocity
was
determined
using
the
time
of
arrival
and the
cross-correlation
between
transducers.
Theoretical
analysis
has
indicated
that the
system
will be
capable
of
resolving
values
close
to the
theoretically
calculated
error
of
less
than
6
%:
this
device
therefore
can
be
readily
realized
as a
compact
portable
field
instrument.
