[pct-l] RE: Gravity

[jdawud at yahoo.com (Junaid Dawud)]

Wow,

I'm pretty damn busy these days working 6days/week
10-12hrs/day, but I'll see if I can find it.  It will
probably take a while, its been a long time since I
was exposed to this info.  A google search is unlikely
to turn anything up (that doesn't mean it is untrue),
perhaps a universities geology/geophysics webpage
would have something....  hmm.  I'll see what I can
do.

As I recall, it was one of my geophysics profs who
last mentioned this.
