POSTDOCTORAL POSITION IN SILICON STABLE ISOTOPE BIOGEOCHEMISTRY.

We seek someone to help us understand why Si dissolved in the oceans is
enriched in Si 30 relative to the Si in igneous and metamorphic rocks; a
question that is fundamental to progress in quantifying the biogeochemical
cycle of Si.  The position entails analysis of isotopic fractionations
occurring during the processes (weathering, clay and phytolith formation,
etc.) that transform Si in rocks into dissolved Si that washes into the
ocean.  The work involves application of a technical breakthrough in
measuring isotopes in dissolved and particulate Si (Anal. Chem.
68,3746-3750, 1996).  We seek an individual with background in
geochemistry, soils or clay mineralogy, preferably with experience with
stable isotopes, and an interdisciplinary interest.  Send resume, including
the names of 3 references, to Oliver Chadwick, Geography Dept. University
of California, Santa Barbara CA 93106.   Email queries about the position
can be sent to Chadwick ([log in to unmask]) or to the other 2 principals on
the project, Mic DeNiro ([log in to unmask]) or Mark Brzezinski
([log in to unmask]).  Position open until filled.  Preliminary
interviews will be conducted with qualified individuals at the Geological
Society of America Meeting in Toronto in October, 1998 or by phone for
those not attending GSA.  Initial appointment 1 year, with additional year
(funding in place) contingent on satisfactory progress.  An EO/AA employer.
