Dear Keith: This can hardly be. How can you be lacking for employment?
There must be something fundamentally screwed up at East Anglia, if not on
the entire island, for you to be in need of funding. Would you consider a
permanent move to Arkansas if we could talk our Dean and Chancellor into a
so-called opportunity hire? Thats where they take discretionary funds to
hire some hot shot scientist that leverages some existing strength at this
University. It would be a tenured professorship in geosciences for the
nine-month academic year. Then you get grants to support your research and
summer salary. Surely you have been offered such positions in the past. I
am of course not sure I could persuade them to go for it, but it is a
possibility. They just hired a GIS jockey from Boston University in our
department through this means, so there is recent precedent. And we are
the favored program at the present time. We are now the Dept of
Geosciences, geology and geography, and we are cooperating with
anthropology to offer a new Ph.D. degree in "environmental dynamics" and
our tree-ring lab is an important part in all of this. Are you quite so
desperate that you would actually consider such a move?? Ed of course
would never let you live it down, but look at his arrangements....he lives
on Long Island!
I have attached the instrumental and reconstructed winter SOI from
our 1998 paper in BAMS; our June PDSI reconstruction for North Carolina
(372-1985, in Science 1988); and our regional and statewide reconstruction
for three southeastern states (the last 1000 years or so, in BAMS 1992).
These attachments are in Mac and PC formats, but they are casewise and
include a descriptive header. I hope you can read them. Write back if
there are any problems.
I just returned from three weeks in Mexico, and we obtained four
excellent collections, including Montezuma baldcypress from Chapultepec
Park in Mexico City, the garden trees of the Aztec Kings! We have another
somewhat more natural cypress collection from Oaxaca, and two Douglas-fir
collections, one from Tlaxcala and the other from the mountains just north
of Oaxaca city at 17 degrees north, some 1000km farther south than I
realized they even existed! It was by far my most successful trip to the
tropics yet. The four collections should go 300 to 500 years, or perhaps
better, and the cypress look excellent with vivid rings and sensitivity.
In Africa, actually Zimbabwe, we now have a Pterocarpus angolensis
chronology that is 206 years long, 1792-1997, but it is poorly replicated
before 1830. Still, I retain hope that we will eventually be able to
improve this chronology. It does have a stong and staightforward climate
signal, a direct correlation with wet season rainfall totals. I hope this
helps. Please write back if you wish more. I will suggest a caption if
you desire, once I know what you want to use. You can also use anything
from the captions in the papers.
Best of luck, Dave
