Session Description:
Nitrogen (N) exerts an important control on marine productivity affecting ocean deoxygenation and climate relevant gases such as CO2 and N2O. Natural and anthropogenic changes can significantly alter the marine N cycle. Understanding what controls the rates and distribution of key N-cycle processes (including but not limited to atmospheric deposition, riverine discharge, N2 fixation, N-loss, nitrification, organic production and recycling) and their interaction with other biogeochemical cycles (e.g. C, P, Fe, O2) is therefore of fundamental importance for predicting the response and resilience of marine biogeochemistry to ongoing climate change and pollution. We invite contributions that use various techniques (such as isotopes, molecular, biomarkers, modelling) to study N-cycle processes, covering diverse spatial and temporal scales. This session strives to bring together observationalists, experimentalists, and modellers to promote an integrated understanding of the N-cycle and its sensitivity to environmental change.
