Professor, Chair *On sabbatical 2016-17 AY*

Background

  • B.A., Environmental Sciences, University of Virginia, 1993
  • Ph.D., Geological Sciences University of California, Santa Barbara, 1998

Teaching

I typically teach a mix of introductory and graduate courses. Here are some of the classes I’ve taught in recent memory:

  •     ESci 400 Freshman Seminar
  •     ESci 409 Geology and the Environment
  •     ESci 420 Our Solar System
  •     ESci 451 Earth in Film
  •     ESci 7/831 Geodynamics (with Margaret Boettcher)
  •     ESci 7/841 Geochemistry
  •     ESci 7/845 Isotope Geochemistry (often with Erik Hobbie).
  •     ESci 7/866 Volcanology (with Joe Licciardi)
  •     ESci 998 Proposal Development.

Research Interests

My primary research interests lie in the application of trace elemental and isotope geochemistry to time and track processes in Earth Surface and Deep Earth environments. We do not discriminate these applications based on temperature windows found in the Earth System. We also have projects collaboratively with faculty in other disciplines (e.g., Archeology) who wish to use these techniques to address important questions reconstructing societal dynamics of earlier civilizations. Here are several ongoing projects that fit under this large umbrella (listed along a quasi-increasing temperature gradient):

  • mercury dynamics in thawing Arctic and changing temperate wetlands
  • wet and dry deposition of trace metals in New England
  • applications of isotopic systems and trace metals for sediment provenance
  • controls on arsenic in New England groundwater drinking supplies
  • geochemical cycling of calcium and magnesium in biological materials
  • hydrothermal vent chemistry
  • linking volatile history with magma genesis in extensional environments
  • geochemical signatures in xenoliths to reconstruct past mantle dynamics
  • basaltic melts as probes to the chemical structure of the mantle

Facilities

The geochemistry group uses the UNH Clean lab, a ~ 1300 ft2 (~120m2) space in James Hall outfitted with minimal exposed metal, Class 10,000 general spaces and Class 1,000 workstations. The clean lab is designed with nested rooms allowing for physical as well as air supply separation of different applications subject to contamination from other procedures.

Our instrumentation is housed in the UNH plasma lab and includes a Nu instruments attoM high resolution single-collector inductively coupled plasma mass spectrometer and a Nu plasma II-ES multicollector inductively coupled plasma mass spectrometer. For sample introduction, the plasma geochemistry lab also includes two lasers (a 193 nm photon machines Excite excimer laser and a New Wave 213 nm deep UV laser), desolvating nebulizers and two hydride generators + cold vapor introduction systems (one typically dated for hydride generation for arsenic applications and a second typically run in cold vapor for mercury analyses). A Milestone direct mercury analysis instrument is available for mercury analysis via thermal decomposition.

Both the UNH Clean lab and the UNH plasma lab include exhausting polypropylene laminar flow hoods, polypropylene laminar flow workstations, centrifuges, balances, ultrasonicating mixers, water polisher systems capable of achieving 18MΩ•cm DI water and Teflon-coated hot plates. Our in situ work is supported by petrographic microscopes, ‘picking’ scopes with variable zoom ranges and rock preparation facilities available through the Department of Earth Sciences.

We are happy to welcome collaborators or contract analyses to the UNH geochemical laboratories. For additional information, discussion of applications including our approved billing rates, please contact us.

Undergraduate and Teacher Members

We have had the privilege of hosting many students and teachers through the lab for a capstone project and in summer research immersion programs. Several have decided to enlist for longer projects or enlist in multiple summers. If you spent quality time in the lab, caught a beautiful sunrise after a fantastic life-empowering ICP or column run and don’t see your name here it means we need an update of where you are now – please drop me a line!

  • John Clark (B.A. Earth Sciences Teaching 2012, now a teacher at Dover Middle School)
  • Alan Jones (B.S. ESCI 2015, now Ph.D. student at UCSB)
  • Madison Myers (B.S. 2010, now in Ph.D. program at University of Oregon)
  • Betsey Pettitt (B.S. ESCI 2015, now Ph.D. student at Renssalaer)
  • Jacob Setera (B.S. 2012, now in Ph.D. program at Rutgers)
  • Don Wason (Dover High School Earth Sciences Teacher)

Student Inquiries

  • We are always on the lookout for students interested in creative applications of trace element and isotope geochemistry. Please email me with your interests and any questions about the application process at UNH.
