Cold season biogeochemistry and carbon emissions in northern ecosystems 

Summer is a great time to measure fluxes of CO2 and methane in northern tundra and boreal ecosystems: It’s warm, it’s bright, plants are growing, students have summers free for internships, only the bugs can be bad. Consequently, most of our understanding of carbon biogeochemistry is based on growing season emissions. However, carbon emissions during the fall, winter, and spring can be an important and overlooked component of annual carbon emissions. This seminar will examine the role of non-growing season emissions in the annual C cycle and explore how cold-season biogeochemistry may differ from the growing season.
