2. At times, when around non-university
graduates, I felt quite smug knowing I
had something they didn't. It was only
when my boyfriend would come home
and talks about his work as a geologist,
or rather a geologist's assistant that I felt
insanely 'dumb'.

3. While I knew about Freud
and Kinney, he knew about
seismology and ground
penetrating radars. He
would sit at the table and
explain these procedures to
me in simple words, making
me gaze in awe and loathing
at his coolness. The ground
penetrating radar was so
intriguing.

4. This ground penetrating
radar (GPR) is, as the name
suggests, a means of
penetrating the ground with
several radars to determine
whether or not an object is
buried underneath the stone,
ice or other structures. It
also identifies any alterations
in the material, and any voids
or cracks.

5. But how? A question I found myself asking numerous
times. Simple, he would say. The radar pulses image
the subsurface and use high levels of electromagnetic
frequencies to be sent into the subsurface. However,
the range of the electromagnetic pulse is measured on
a spectrum and is limited by the conductivity of the
ground.

6. I asked him again, what does he
mean? He said that if conductivity
is high, the penetration depth is
low because the electromagnetic
energy disappears into the
substructure's heat causing a loss
of signal.

7. GPR are easy to use, safe and more sophisticated
than most methods in geology. I wish I had more
access to them in my studies.
