B020: Comparative Organic Geochemistry of Soils and Aquatic Sediments: A New View in the 21st Century

Session Description: The benchmark paper by Hedges and Oades (1997), entitled “Comparative Organic Geochemistries of Soils and Marine Sediments”, in part concluded that “the time is ripe for increased interaction among chemists studying the parallels and contrasts of organic matter in soils and sediments.”  So where are we now in the 21st century in bridging the gap between soil and sediment biogeochemical dynamics, two decades after this paper was published?  This session will focus on new paradigms and novel analytical techniques that have allowed for improved comparisons across soil and aquatic sediment systems. We invite papers that address all aspects of organic geochemical/biogeochemical processes in soils and aquatic sediments that expand our understanding of organic matter characterization, rates of decay, linkages with new “omics” techniques and microbial processes, new biomarker applications, and priming, to mention a few, that will help to better constrain carbon burial rates and turnover in a warming climate.
