Information

Aims, contents and method of the course

Lecture Description
Our focus will be on the biogeochemistry of soil organic matter in climate-affected ecosystems.

Learning Objectives
• Students will learn fundamental principles of soil organic matter biogeochemistry such as sorption/desorption, oxidation-reduction, thermodynamics, and biodegradation.
• Students will learn effects of forest fires and permafrost thaw on soil organic matter cycling and water quality.
• Students will learn to advanced characterization techniques for soil organic matter.

Assessment and permitted materials

Minimum requirements and assessment criteria

Based on a percent scale where 100% is the highest obtainable grade the students will be evaluated as follows: In-class participation (10%), Homework (40%), and Project presentation (50%).

Examination topics

This class will meet four times over a two-week period. Grading will be based on one assignment in which students will present a small group project orally in class and one homework.
The homework will consist of multiple questions that relate to the carbon biogeochemistry learnt in-class Students will be given one week to prepare a small group project that will focus on the impact of climate change on carbon cycling. This project will be evaluated based on an oral defense of the project.
