Last Thursday night,  our local PBS Radio affiliate, KPCC in Pasadena, ran the
usual Thurs. "Air Talk" edition featuring JPL and Caltech interests.  This 
particular discussion was with a gentleman from JPL who (I believe) discovered
GPR and used it with a particular archeologist friend, to discover the 
purported sight of the lost city of Ubar in the Sahara Desert.

The researcher, Dr. Ron Bloom of JPL,  said that this technique is
very specialized in applications.  They instuments that they utilized worked
only because of the extremely dry sands of the Sahara and only penetrated
up to 10 meters into the sand.

We are active users of Ground Penetrating Radar.  In fact, I did several months
of extensive study and some basic research into GPR and took a short course
at UCLA on Synthetic Aperature Radar to better appreciate the potential of GPR.

We are using, in part, a Titan 3000VS system running AVS for visualization
and analysis of some of the GPR "images" we acquire with a PC-based GPR data
acquisition system.

The GPR community is small (few manufacturers, probably less than a hundred
academic/research users).  If I can help you in any way:

The affinity for coal is mainly due to the depositional environment.
The actinides are removed from solution by the vegetation in anoxic
environments at the bottoms of marshes, etc.  This concentrates the actinides
(and other metals that behave similarly) in the vegetation.  This is
further concentrated by dewatering and lithification.  If there is a
lot of fluid circulation during lithification, the coal deposit can remove
even more from these fluids and thus produce recoverable concetrations
of Uranium (there are stories of entire logs replaced by carnotite - a
Uranium ore).

Oil and gas are not identical to this.  Oil forms from the alteration
of a waxy organic substance found in marine shales - kerogen.  Concentrations
of actinides are low in this environment, so there isn't much to get.  Also,
the production of petroleum relies on the migration of the liquid oil.
This means any actinides removed from solution by reaction with kerogen
would be left behind in the source rock as the oil migrates to the reservoir
rock.  Actinide oxides would have low solubility in oil, so the oil will
not scavenge these from the reservoir rock.  And the oil itself will prevent
brines from contaminating the oil.  So oil is not a problem.  (Radon
will dissolve in both oil and gas, so radon could be a problem, but no
more than in well water).  Gas will not carry actinides.

M is the magnitude of the earthquake, I is intensity.  M and I are fundementally
different.

I is normally measured in terms of peak amplitude.  This must be measured
on a particular phase in a particular frequency range.

I0 is then the amplitude that would be measured for a quake of magnitude 0
in that same frequency range, for the same phase, on the same seismometer
and at the same distance.

Sometimes, magnitude is computed this way, and a table of I0 for the
various distances is used to lookup I0 and compute M.  Normally, however,
an expression can be written that incorporates the distance dependence,
and corrects for frequency range.  For example, the surface-wave magnitude
(MS) proposed by Vanek (originally proposed by Gutenberg and Richter) is

MS = log(A/T)max + 1.66*log(D) + 3.3

Where A is amplitude, T is period and D is distance (in great-circle degrees).
A is corrected for instrument impulse response before using it in this
formula.

Interesting interview on NPR last night with a survivor of the Colombia 
eruption that killed several geologists. I don't remember his name, but 
he spoke from an east coast hospital where he was being treated. 

He made no mention of anything that might have been a warning of the eruption.
They had been exploring a young crater within an old caldera. Most of them
had emerged from the young crater after their studies and were heading down
the outer slope of this inner cone. One geologist, a Russian, remained 
behind for a cigarette, and appeared to be relaxing a bit and enjoying the
scenery. He was not seen again.

Apparently without warning (he did not specifically say this), they heard 
a loud boom, looked up, and saw the sky full of rocks in ballistic flight.
It sounded as though most of the fatalities were from the fall of these
rocks. The interviewee was grazed by one and suffered a skull fracture and
lacerations. He personally saw a Colombian crushed by a large rock.

Other injuries were burns. Some of the rocks landed in soft ash beds, 
creating impact craters. During their frantic and exhausted scramble over
the unstable and rough terrain, they would sometimes fall in these craters.
When struggling to their feet, they would contact the fresh hot rock in the
middle, suffering contact burns. 

The interviewee became exhausted about 1/3 of the way up the caldera rim
and had to be stretchered the rest of the way.

He made no mention of gases or ash clouds. Neither did he mention any 
continuation of the eruption after the intial explosion.

3. What is the level of computer exposure of the average geoscience

In Ontario, there is a lot of talk about the "high-tech" mineral

quantitative or even qualitative surveys asking geologists just how 
much they know and use computers.  What about the rest of the world?

I only caught the last few minutes of that part of the broadcast, but the
system they were using looked like one of the ones made by a company
called:"Geophysical Survey Systems, Inc." (aka GSSI), P.O. Box 97, North
Salem, NH  03073-0097.  GSSI has used their equipment to look for voids in
pavement, rotting railroad ties, and many other things, including
archeological exploration.  From what I can tell, their equipment is
probably the most prevalent.  My last price list from GSSI showed one of
their systems selling for around $35,000.

I have addresses of other people who sell GPR equipment.  If you are
interested, I can e-mail them to you.  

So, what is your interest in GPR?  Here at Georgia Tech, we have done some
research in this field.  There are several other institutions which have
done more research in this area than we have.  I could try to round up a
list of those, too. E-mail me directly, if you want them.

So, did anyone else recognise the equipment used???
