Dear all,

Please support our community in Earth and environmental sciences by attending our weekly events. This week's speaker in our Enviro-lunch brown bag seminar series will be:

Dr. Caitlin Hicks Pries
Lawrence Berkeley National Laboratory

Digging Deeper: The Vulnerability of Soil Organic Carbon to Climate Change


Soil organic matter stores ~3000 Pg C, about four times the amount of carbon as is currently in Earth’s atmosphere. As rising temperatures increase microbial activity, some of this carbon is at risk of being respired to the atmosphere, creating a positive feedback to climate change. To estimate the magnitude of this feedback we need to understand how mechanisms controlling soil carbon decomposition change throughout the soil profile and how these mechanisms respond to warming. Here I present results from several experiments examining how mechanisms controlling soil carbon decomposition change with depth. The understanding from these experiments is then applied to one of the first experiments warming a whole mineral soil profile in situ.



Where: SE2-302
When: TODAY Thursday (March 23th, from 12-1:30PM)


We look forward to seeing you,

Organizers for 2016-17: Rebecca Abney and Fernanda Santos
