GEOSC413 Techniques in Environmental Geochemistry
Instructors:  Susan L. Brantley Katherine H. Freeman, Dave Eggler

Text: J.I. Drever, Geochemistry of Natural Waters, 3rd Edition

Credits: 3

Short Description: This course teaches techniques needed for the collection, chemical analysis, and data analysis of environmental samples.Geosc 413 includes lectures, field, laboratory, and library work as well as student discussions. The course incorporates a limited number of lectures and extensive hands-on experience for all students.The emphasis in the course is collecting data for field projects, and interpreting that data. As part of the course all students must hand in written reports that represent their own writing and their own thought. However, in the laboratory and field, students work in pairs or threesomes. Lab groups are also encouraged to share their data so that reports can be written with more comprehensive datasets.Grades are based on the quality of written reports and both conceptual understanding and writing technique are emphasized.
