Exchange of N2O between soils and the atmosphere: patterns, processes and analytical tools

Joe von Fischer, Emily Stuchiner

Description:Nitrous oxide (N2O) is a potent greenhouse gas that contributes to climate change. N2O receives considerably less scientific and public attention than CO2, in part because it has a smaller climate impact than CO2, but also because the processes leading to N2O emissions are considerably more complex and therefore difficult to predict. This seminar will examine the factors that regulate N2O emission rates, and the tools that have been used to study N2O fluxes. The primary approach will be from an ecosystem perspective, with dives into details of the microbial processes and zoom out to the global budget. Class will assume a basic understanding of the nitrogen cycle. Class will primarily entail group discussions of papers. We will select weekly readings that address the factors that influence N2O production over a variety of spatial and temporal scales. We aim to tailor this course to student interests, but there are several key objectives we hope to fulfill throughout the semester: 1. Gain familiarity with the methods used to measure N2O. 2. Develop a mechanistic understanding of the nitrogen cycle and the particular microbial processes that contribute to N2O flux. 3. Compile a library (eg. a Mendeley folder) of papers on this topic that span a broad array of ecosystems, spatial and temporal scales, and methodologies. 4. Develop a professional network with guest speakers and lecturers who are experts in this field (in-person and/or over Skype). This class will meet once weekly and the meeting time will be determined based on registered students' availability. Note: meeting time options are limited to the conventional� work week (Monday-Friday 9 AM to 5 PM), and if no meeting time works for everyone a time will be selected that maximizes participation.
