Mentor Scientists: Dr. Jonathan Halvorson

Project Description: This project has three specific goals; a) determine the appropriate conditions (temperature and time) needed to maximize extraction of C and N from soil with water; b) compare extraction efficiencies from fresh and dried soil; and c) quantify patterns of soluble C and N as a function of depth. Soil samples needed for the project will be collected from ongoing long-term experimental plots or archived samples located at the Northern Great Plains Research Laboratory (NGPRL). Sample processing and analyses will be conducted using existing facilities, instrumentation, and technical assistance at NGPRL. These activities will offer both field and laboratory experience and should also offer the intern a chance to interact with other location scientists and technicians. The intern would be expected to develop a scientific presentation for location staff and others and compile the information in tables and graphs for use in scientific publications and grant proposals.

Preferred/Required Experience: Coursework in chemistry, soils, ecology or environmental science would be preferred. Previous experience in laboratory or field environments is preferred. Experience with Excel, PowerPoint, and Word is preferred.

Pay Grade/Hourly Salary: GS 3 $12.07/hour; typically requires one year of college and 6 semester hours of math/science courses.
