POSITION ANNOUNCEMENT
Department of Renewable Resources, University of Wyoming, Laramie

TITLE: Assistant Professor, Water Quality/Aquatic Chemistry
POSITION AVAILABLE: August 1, 2000
APPLICATION DEADLINE: May 1, 2000, or until suitable candidate is found

RESPONSIBILITIES: The Department of Renewable Resources, College of
Agriculture, University of Wyoming, is seeking candidates for a
tenure-track, 9-month faculty position to strengthen our Water Resources
program. The position is 50% teaching and 50% research at the Assistant
Professor level. The successful candidate will be expected to teach
undergraduate and graduate courses in subjects relating to aquatic
chemistry, water quality, and remediation of water contaminants at the
watershed scale; and develop a research program addressing water quality
issues associated with nonpoint-source pollution and Total Maximum Daily
Load (TMDL).

MINIMUM QUALIFICATIONS: A Ph.D. degree in non-point source, water quality or
a related science; demonstrated academic and/or professional experience in
TMDL nonpoint-source aquatic chemistry and effective teaching; excellent
oral and written communication skills, ability to work with diverse Wyoming
clientele, and commitment to economic development through academic programs
are required.

PREFERRED QUALIFICATIONS: Demonstrated publication track record in
appropriate media; demonstrated ability to teach university courses in water
quality; field and laboratory experience in conducting water quality
research associated with nonpoint-source pollution  issues, and demonstrated
grantsmanship in crafting  multidisciplinary, externally funded research
program in water quality involving productive working relationships with
clientele groups (e.g., agricultural producers, mineral and gas producers,
landowners, citizens, industry affecting water quality and regulatory
agencies.

SALARY AND BENEFITS: Competitive and commensurate with qualifications.

LOCATION: The University of Wyoming is located in the Northern Mixed Prairie
at Laramie, Wyoming, which has a population of about 27,000. Wyoming is a
major producer of coal and petroleum, coal bed methane, livestock, wildlife,
recreation and water. The campus and community is surrounded by superb
opportunities for outdoor activities, and both the state and the university
are strongly committed to natural resources and their proper management.

APPLICATION: Applicants should submit a letter of application, curriculum
vitae, academic transcripts, and the names of three references familiar with
your professional capabilities to:

Dr. J. Daniel Rodgers, Chair, Water Quality Search Committee

Subject: Re: 18O at molecular level


Jeremy,

I guess your question refers to compound specific 18O analysis? And the
question concerning IRMS doesn't really mean IRMS, but CF techniques, right?
Compound specific and continuous flow means GC-IRMS (separation of mixture,
on-line conversion in He-stream and isotope ratio measurement), so the
compounds you want to analyze have to be volatile, or you'll have to
transform them into volatile compounds (e.g. derivatization).
GC-Pyrolysis-IRMS systems for del18O (and d2H) analysis are commercially
available today, but the impression I got from talks with colleagues who
work with such a machine  for 18O/16O analysis comes pretty close to what
Arndt Schimmelmann wrote in his answer to your query...
To my knowledge, there's only one reference using GC-Pyrolysis-IRMS for
del18O analysis: Hener et al, Z. Lebensm. Unters. Forsch. A 206, 230
(1998). They analyzed vanillin, but there was no analysis of complex
mixtures. And I'd rather not comment on their relating their values to
their internal lab gas standard... Well, there's no straight forward
solution to the standardization problem of these systems, as long as no
volatile organic reference materials are available.
I guess it tells us a lot that since 1998 these systems are commercially
available, but no other papers from researchers using this technique for
del 18O measurement did follow...
If I missed something out there, please correct me. And maybe some users of
a GC-Pyrolysis-IRMS system for 18O analysis could share their experiences?
Thanks

Barbara
