Methane and nitrous oxide emissions from coastal, estuarine and freshwater systems in subtropical Australia

Abstract

During 2010 - 2012, we studied CH4 and N2O fluxes from a subtropical coastal embayment, an estuary and four lakes for urban water supplies, which are of different sizes (49 – 10,940 ha) and catchment characteristics. We used both indirect (based on surface water CH4 and N2O concentrations and gas transfer models) and direct (flux chambers and robotics) methods to quantify the fluxes...
