Article Type: 
Start Date: 
Tuesday, July 21, 2020 - 16:30 to Thursday, July 30, 2020 - 16:30

Dear colleagues,

We write to encourage you to submit abstracts to the session titled “Earth Surface Processes and the Global Carbon Cycle” at the upcoming AGU 2020 virtual fall meeting. This session aims to bridge many aspects of Earth-surface carbon cycling. Our invited speakers will be:

Marisa Repasch, GFZ German Research Centre for Geosciences

Xin Gu, Pennsylvania State University

The abstract submission deadline is 29 July; we particularly encourage submissions from early career researchers and researchers from underrepresented groups. Please find the session description below, and do not hesitate to reach out with questions.


Session Conveners

Emily Burt, University of Southern California (

Jordon Hemingway, Harvard University (

Preston Cosslett Kemeny, Caltech (

Mark Torres, Rice University (

Session Number: EP013

Session Description: The carbon cycle plays a central role in Earth’s climate system and the habitability of our planet. While many biogeochemical reactions contribute to carbon transformations, Earth surface processes are thought to play an important modulating role through their influences on reaction timescales, the physical properties of soils/sediments, and mass fluxes, among other key parameters. Here, we solicit contributions that investigate the coupling between surface processes (e.g., erosion, fluid flow, and sediment deposition) and carbon cycling (organic and/or inorganic). We welcome submissions at a range of spatial (soil/hillslope, watershed, global) and temporal scales (modern to the geological past), and from diverse climatic and tectonic environments. Contributions may range from field studies to laboratory experiments, proxy studies utilizing isotope geochemistry, and theoretical and modelling studies. By bringing together researchers in the fields of surface processes, biogeosciences, hydrology, and everything in between, we aim to build a holistic understanding of the carbon cycle.
