Dear colleagues, Please consider submitting an abstract to our session at the AGU 2014 Fall Meeting.
Abstracts are due August 6, 2014: http://fallmeeting.agu.org/2014/scientific-program/ *Session Title*: *Molecular, genomic and isotopic approaches to resolving biotic and abiotic pathways of nitrous oxide production in terrestrial and marine ecosystems* *Session ID#*: *2270* *Confirmed Keynote Speakers: **Lisa Stein, William Horwath, Nicole Wrage-Mönnig* *Session Description:* Nitrous oxide (N2O) is a potent greenhouse gas and the major source of stratospheric ozone depletion. N2O concentrations are rising in the atmosphere, likely due to increased anthropogenic nitrogen fixation. N2O can be produced by both biological and abiotic chemical reactions. Microbial denitrification, nitrifier-denitrification, aerobic hydroxylamine oxidation and detoxification pathways produce N2O enzymatically, while chemical reactions such as chemodenitrification produce N2O abiotically. In recent years, our knowledge of the N2O cycle has undergone dramatic changes, with discoveries of new N2O-producing microbes, a broader diversity of N2O-consuming enzymes and novel isotopic strategies for resolving the mechanisms behind N2O cycling in both terrestrial and marine ecosystems. In this session, we welcome submissions on any aspect of N2O cycling in natural ecosystems or laboratory experiments, including but not limited to molecular, genomic, electrochemical and isotopic approaches. We specifically seek to bridge gaps between soil and ocean communities studying N2O. *Primary Section/Focus Group:* Biogeosciences *Co-Sponsor(s):* · A - Atmospheric Sciences · GC - Global Environmental Change · OS - Ocean Sciences · V - Volcanology, Geochemistry and Petrology *SWIRL Theme: *Global Soils *Index Terms:* 0414 Biogeochemical cycles, processes, and modeling [BIOGEOSCIENCES] 0465 Microbiology: ecology, physiology and genomics [BIOGEOSCIENCES] 0469 Nitrogen cycling [BIOGEOSCIENCES] 0490 Trace gases [BIOGEOSCIENCES] Sincerely, Jennifer Glass (Georgia Institute of Technology) Xia Zhu (University of California Davis) Nathaniel Ostrom (Michigan State University) Jennifer Glass, PhD Assistant Professor School of Earth and Atmospheric Sciences & Biology (courtesy) Georgia Institute of Technology Cell: 480-244-3603 Office: 404-894-3942 http://www.eas.gatech.edu/people/Jennifer_Glass
