Chappaz publishes article in Geochimica et Cosmochimica Acta
April 11, 2013 - Assistant professor of geochemistry Anthony Chappaz, along with co-principal investigator Dr. Jennifer Glass from the California Institute of Technology, recently published in the recognized geochemistry journal, Geochimica et Cosmochimica Acta. Their article is entitled "Molybdenum geochemistry in a seasonally dysoxic Mo-limited lacustrine ecosystem."
Molybenum (Mo) and nitrogen biogeochemistry are intrinsically associated, with Mo being required for the nitrogenase process to occur. The research site, Castle Lake in northern California, had previously been widely studied regarding nitrogen biogeochemistry, however Chappaz's research is the first of its kind to focus specifically on Mo, and sheds new light on the Mo sources influencing this lake. It also is the first to provide Mo isotopes' measurement for a dysoxic environment.More details about this article and Dr. Chappaz's research can be found by visiting his GEM Lab website.
Chappaz publishes article in Environmental Science & Technology
February 19, 2013 - Assistant professor Anthony Chappaz
and his collaborator, Dr. Jeff Curtis from the University of British
Columbia - Okanagan, just published a research article entitled,
"Integrating Empirically Dissolved Organic Matter Quality for WHAM VI
using the DOM Optical Properties: A Case Study of Cu-A1-DOM
Interactions," in the Environmental Science & Technology journal.
They demonstrated that the type of dissolved organic matter (DOM), as
well as the A1 competition, affect the Cu complexation by DOM. More
importantly, they provide a new method to integrate these changes for
the widely used software, WHAM, that predicts metal speciation (and
therefore toxicity) in aquatic systems.

Journal article by Sirbescu is one of the most downloaded
February 5, 2013 - A 2008 journal article by associate professor of geology Mona Sirbescu, Emily Hartwick, a former CMU geology major and faculty member Jim Student had the highest number of weekly downloads during the first week of January 2013, according to the Contributions to Mineralogy and Petrology journal's website.
Click here to download a PDF of their article titled, "Rapid crystallization of the Animikie Red Ace Pegmatite, Florence County, Northeastern Wisconsin: Inclusion microthermometry and conductive-cooling modeling."
Contributions to Mineralogy and Petrology is an international journal that accepts high quality research papers in the fields of igneous and metamorphic petrology, geochemistry and mineralogy. With a five-year impact factor of 3.900, the journal ranks second highest in the category of 26 mineralogy journals.

Meteorology student places first at National Weather Association annual meeting
November 9, 2012 - CMU senior and meteorology major William A. LaForce recently won the best undergraduate student poster award at the 2012 National Weather Association annual meeting held from October 6-11 in Madison, Wisc. Second and third place awards went to students from the University of Missouri at Columbia and the University of Miami.
LaForce's project was entitled, "Comparison of Two Forecasts for Tornadoes Associated with Cold-Core 500-mb Lows: Surprise and Bust." Associate professor of meteorology Martin A. Baxter served as LaForce's faculty advisor.
In 2005, the NWA Weather Analysis and Forecasting (WAF) Committee initiated the addition of Best Student Presentations to the annual NWA Awards Program. At each yearly meeting, students (undergraduate and graduate) submit their abstracts to be considered for these awards. Members of the WAF Committee review each presentation and recommend their choices of the best to the NWA President for approval, who awards the students with a congratulatory letter, a cash stipend and complimentary NWA membership for the following year.
This is the third year in a row that a CMU student has won first place at this event.
