A Ph.D. assistantship is available at Florida International University in Miami beginning in Summer or Fall 2009 to study denitrification and other aspects of nitrogen cycling in spring-fed and blackwater rivers of North and Central Florida. This research provides an opportunity to integrate high-resolution in-situ sensor measurements of NO3, estimation of denitrification via open channel N2 flux methods, and isotopic approaches in order to evaluate N dynamics along gradients of ecosystem productivity and nutrient enrichment. The student will join a broader research team investigating interactions among karst aquifer hydrology, carbonate and nitrogen biogeochemistry, and river ecosystem metabolism. This research is supported by grants from the National Science Foundation and the St. Johns River Water Management District. Applicants should send a CV, statement of research interests and experience, a summary of relevant coursework (with GPA and GRE scores), and names of 3 references to Dr. Jim Heffernan ([email protected]<mailto:[email protected]>; 352-846-0353). Review of applications will begin January 15th but may continue until the February 1st deadline for applications to the FIU Department of Biological Sciences (http://www.fiu.edu/~biology1/).
