As a result of natural and anthropogenic processes, rivers, estuaries, intertidal (“blue carbon”) and coastal margins provide a central link between the land and ocean. An important emerging research priority is to therefore understand and quantify sources, sinks and subsidies of carbon in-and-across these environments and to understand the long-term stability of these carbon pools.

The session will explore the research activities that address the sources, sinks and subsidies of carbon across the land-ocean continuum, which has been significantly altered by humans (e.g., aquatic critical zones), to better assess how this dynamic region is being impacted by climate change and land-cover/land-use change.

This session invites contributions on research across the land–ocean continuum a broad range of spatial (Local to the Global) and temporal scales (Past, Present and Future).

This session is multidisciplinary and is open to observational, modelling, theoretical and policy-based studies in order to promote dialogue across the breadth of disciplines.
