Dear colleagues, We write to encourage you to submit abstracts to our session<https://agu.confex.com/agu/fm21/prelim.cgi/Session/121946> titled “Earth Surface Processes and the Global Carbon Cycle” at the upcoming AGU 2021 Fall meeting. This session aims to bridge many aspects of Earth's surface systems and to advance our understanding of the interplay between surface processes and the carbon cycle. Our invited speakers will be: Dr. Katherine Lininger, University of Colorado Boulder Dr. Maria Chapela-Lara, GFZ Potsdam The abstract submission deadline is tomorrow, August 4. We particularly encourage submissions from early-career researchers and researchers from underre∫presented groups. Please find the session description below, and do not hesitate to reach out if you have any questions. Sincerely, Session Conveners Emily Burt, University of Southern California (eburt@usc.edu<mailto:eburt@usc.edu>) Preston Cosslett Kemeny, Caltech (pkemeny@caltech.edu<mailto:pkemeny@caltech.edu>) Nicole M Fernandez, Cornell University (n.fernandez@cornell.edu<mailto:n.fernandez@cornell.edu>) Gen Li, Caltech (ligen@caltech.edu<mailto:ligen@caltech.edu>) Session Number: EP009 Session Description: The carbon cycle plays a central role in Earth's climate system and in regulating long-term planetary habitability. While many biogeochemical reactions contribute to carbon transformations, Earth surface processes play an important modulating role through their influences on reaction timescales, the physical properties of soils/sediments, and mass fluxes. Here, we solicit contributions that investigate couplings between surface processes (e.g., erosion, fluid flow, and sediment deposition) and carbon cycling (organic and/or inorganic) across environments. We welcome submissions across a range of spatial (soil, hillslope, watershed, global) and temporal scales (modern to the geological past). Contributions may span from field studies to laboratory experiments, proxy studies utilizing isotope geochemistry, and theoretical or modeling research. By bringing together researchers in surface processes, biogeosciences, hydrology, and everything in between, we aim to build a holistic understanding of the carbon cycle. We welcome student submissions and aim to give talks to a diverse range of researchers.
