Coastal lagoons are extremely productive ecosystems with global prevalence, accounting for 75% of marine methane emissions while covering only 15% of the ocean surface. However, carbon cycling within these important ecosystems remains poorly understood and is currently misrepresented within global climate models. 

​

The project will focus on the Coorong as an outstanding opportunity to develop the understanding of how salinity and sulfide toxicity on methane flux, which will be crucial for informing management of Coastal lagoons and salt lakes globally.
