BN022:
Understanding Controls on Marine Nitrogen Cycling: From Microbes To The Global Ocean


Session ID#: 27830

Session Description:
Marine nitrogen (N) exerts an important control on marine productivity affecting climate relevant gases such as CO2 and N2O. Understanding the controls of the rates and distribution of N-cycling processes (inventory-altering and internal-cycling N processes, such as atmospheric deposition, N2 fixation, denitrification, nitrification, and N2O production) and their interaction with other biogeochemical cycles (C, P, Fe and O2) is therefore of fundamental importance for predicting the response of marine biogeochemistry to ongoing climate change. Recent advances in N-cycling have come from diverse research fields spanning from novel molecular tools, refined isotopic techniques to global biogeochemical modelling. We invite contributions that use diverse approaches (such as stable and radiogenic isotopes, trace elements, biomarkers, and modelling) to study marine N-cycle processes, covering diverse spatial and temporal scales. This session strives to bring together observationalists, experimentalists, theoreticians, and modellers to promote an integrated understanding of the N-cycling processes that have a critical role in the Earth's climate system.
