Paleomagnetic field work
This may be me. I can't be sure.
After reading
about cool hikes and hair-raising adventures in the mountains, a history of my
“adventures” in science will be pretty dry.
However, it’s part of the story, so here goes.
I have
covered some of my work history already – for instance, my efforts for the
Beaumont Hardware and Lumber Company. In
some ways that was more fun than anything I have done subsequently. For shear personally satisfaction, driving a
truck beats drilling rocks or giving lectures pretty much any day. However, it pays a lot less – and, although I
was a very bad truck driver, I was pretty good with rocks. So I will skip that part. My second “career” was with the U.S. Army, in
which I served 1955-57 is subject of an essay all its own, which I have covered
already, so I will skip over it, too, and go straight to: GEOLOGY.
You might
well ask, “why geology?” Well, there
were three reasons. First, my mother’s
family had been into mining – and thus geology – for several generations. For all my growing-up years I had rocks
thrust into my face, accompanied by the question “Look, Myrl, Jr., isn’t this
interesting?” Actually, it almost never
was the least bit interesting – but it made me acutely aware of the science of
geology. Second, my best friend at
Caltech – Sam Sims – went into geology and always seemed to be doing fun things. And finally: like most young people I thought
that working at geology meant healthy and exhilarating rambles in the
mountains, with only short trips to the office now and then. As an aside - it doesn’t.
Anyway, when
I got out of the army (1957) I went back to Stanford to get a Ph.D. in geology. I had graduated from Stanford with a B.A. in
economics, and I had only one course in geology on my record, so this promised
to be a long haul. Fortunately I had all
the required math, physics and chemistry, from my Caltech year, but I still had
to do most of the B.S. requirements, and then the graduate work. No sweat: I was young; I had pretty good
financial support from the school, no kids, and a working wife. So I went at it hammer and tongs and made
excellent progress. Then I hit a mental roadblock.
It seems
that, to get a Ph.D., you have to pass an oral examination, and also orally “defend”
your thesis. It is hard to believe now,
but at that point in my life I was terrified of talking in front of anybody but
close friends. (Now, of course, I think
it’s a kick in the pants.) I watched
other grad students get marinated, skewered, and roasted on a spit by the Stanford
geology faculty. Most of them passed
eventually, but the process absolutely terrified me. So, to my eternal shame, I bailed – took an
M.S. (using the research I had already started), and went to work for Standard
Oil Company of California, in Oildale, near Bakersfield, California.
My thesis,
by the way, concerned “paleomagnetism” – the permanent magnetism often retained
by rocks from the time they come into existence, and what you can learn about
the earth by studying it. It turns out
you can learn a lot of things, many of them important, and some undetectable in
any other way. But more on that
later. As it happens, I was nearly a
founding father of that scientific art.
Chevron, of
course, didn’t give a fig about paleomagnetism.
I had an M.S. from a top school, good grades, and took showers every few
days, so they hired me at the going rate – I think, about $6000/year. (This must have been about 1961,) They set me to doing the most pedestrian,
most mind-rotting sort of stuff – basically, matching up “well logs” from one
drill hole to another, and trying to construct a sub-surface structural map
therefrom. Yes, yes – I know it was
important. But it also was poison for
the soul – or, at least, to my soul. I
suspected that, if I stayed with Chevron, eventually I would make a lot of
money. I also realized early on that the
oil business could be extremely absorbing, and potentially rewarding even in a
non-monetary sense, if you regarded it as a business. But, at that tender age, I wanted to be a
real SCIENTIST!
(Sometimes I second guess myself.
It would be nice to have $100 million to donate to ovarian cancer
research. Or even $1 million. But, no – on balance I was far better off in
pure research.)
So, after
only about one year with Chevron I got the offer of a position with the U.S.
Geological Survey, in Washington, D.C., and I jumped at it. By now I had two kids, a pregnant wife, and
not much money. The job required me to
live in or near Washington, D.C., which is an expensive place. Furthermore, I took a pay cut. But the work was far more interesting, and
gave me a measure of independence. I did
field work all over the place – from Virginia to Minnesota. None of it particularly shook the earth, but
it was a solid beginning. And all the
time my poor wife, Virginia, had to cope with three kids and relative
poverty! I would have been content to
stay with the USGS for the rest of my career except for two things: I didn’t
want to live on the east coast, away from “real” mountains, and my boss was
slowly giving me ulcers.
My boss was
a self-made leader in geophysics – trained as a mathematician – who all but
gave birth to the art of aeromagnetic surveying His name was Isadore Zeitz. Izzy was branch chief for the Regional
Geophysics Branch, which was supposed to do practical surveys and experiments,
leaving the more cerebral stuff to the Theoretical Geophysics Branch. I desperately wanted three things: to get into the other branch, get back west,
and get away from Izzy. Izzy was loyal
to his troops and always willing to help, but his idea of management was to
open your office door, turn blood red, and shout. He never seemed to be relaxed, and he
frequently seemed greatly outraged. His
face was usually a dull red in color. We
all thought he was a heart attack just waiting to happen. Izzy died last year, at the age of 96.
Well, I
applied several times for a transfer to either of the two other regional
centers for the USGS: Menlo Park, California, or Denver, Colorado. Other people got transferred, but they usually
did so by using one powerful tool – they would threaten to quit and go to work
for a university. But I couldn’t make
that threat: I lacked the proper union card, a Ph.D. So I was stuck. Finally, in desperation I took a leave of
absence from the Survey and enrolled at U.C., Riverside, where in 1969 I
finally earned that all-important union card.
But, then,
having qualified for a university position, I decided to see what such a job
was like.
There were
two vacant positions on the west coast at that time: San Diego, and
Bellingham. I chose the latter for two
reasons: a smaller teaching load, and first-class mountains nearby. I fully intended to return to the Survey after
a few years, but I never did, and I have never regretted the choice. For all its “iffy” weather, Bellingham turned
out to be the best place on earth – at least for me.
So, I moved
upward through the ranks at WWU swiftly, mainly because I was publishing lots
of papers. I was a good teacher, but
never a truly outstanding one. I like to
think that this was because my proclivities and talents bent naturally toward
the research aspect of the job, at the expense of all the other parts. I was a lousy participant in “university
governance”, as all those committees were called. I met my classes and did a good job, although
my best teaching probably was with graduate students. I started at WWU in 1969 and retired at the
end of 1997. I received the first
Outstanding Researcher award, in 1984, but I never was the Outstanding Teacher,
although I was nominated a few times.
I was
fortunate enough to secure quite a few National Science Foundation grants,
which allowed me to do field work nearly every summer (and also to evade the
financial necessity of teaching summer school.)
Here are some of the places I have worked (this list includes field work
for the USGS.) In chronological
order: the Appalachians, the Great Lakes
area, Colorado, Washington, Oregon and California, Nevada, Colombia, Chile and
Argentina, the Caribbean (Barbados, Granada, Tobago, St Vincent and the
Grenadines), and Greece (the islands of Lemnos, Lesbos and Samothraki). Of these, the work in Washington and Oregon
probably was the most significant, but the trips to Greece and Chile were the
most fun!
Note that
all this travel, while remunerative in several ways, also was hard work. For example, in South America one did not
stay in fancy resorts or eat gourmet meals off linen tablecloths. Rather, one slept in tents or crappy rooming
houses and ate stuff one could cook.
Yes, we had some blow-out meals, but mostly it was tough beef, bread,
and rot-gut red wine. Also, showers
could be scarce and sporadic – and drilling rock is a muddy business. More than once I have gone for a week without
changing my underwear – but you didn’t want to know that. Suffice it to say that we knew where all the
hot springs were in southern Chile.
Okay, 1500
words already and you are getting bored.
Let me tell you, nutshell-like, what all this research was about. Fundamentally it was aimed at understanding
the birth and evolution of mountain ranges.
How paleomagnetism can contribute to this is, as authors frequently say
when they don’t want to get side-tracked, “beyond the scope of this review”. In another nutshell - paleomagnetism
sometimes can indicate how a particular block of rock has moved – rotated, moved
north or south, or both – since it formed.
Thus we have shown that pieces of the west coast of North America have
move northwestward along the continental margin by large distances in the last
100 million years or so. By contrast,
using the same technique it can be demonstrated that similar pieces of the
western edge of South America have not moved either north or south, but rather have
rotated in place like ball bearings.
Observations such as these then open up tempting vistas for speculation
about how and why these things occurred, and I have always been addicted to
speculation.
One might
say that this novel way we used paleomagnetism was a new and logical outgrowth
of plate tectonics. It was moderately
important, and continues to be. None of
us won the Nobel Prize, for sure, but at least we didn’t have to teach Geology
101 during the summer to keep bread on the table. And it was fun.
Glad you were able to earn a living doing work you came to love (and wear clean undies more frequently :D ) btw - I'm forwarding these to Joyce Wilson, and she's thoroughly enjoying them too.
