Study links shoreline migration to blue carbon storage in coastal river deltas
By
Eileen Hofmann
Summary
This article highlights a study by Silvestre et al. [2026] published in AGU Advances, which presents an experimental framework linking shoreline migration to preserved organic material in subsurface coastal marshes. The research focuses on how autogenic (self-driven) processes of sediment storage and erosion regulate shoreline movement, influencing where coastal wetlands develop and creating subsurface areas of preserved organic matter (blue carbon). Coastal river deltas are identified as important long-term carbon sinks in the global carbon cycle.

Autogenic processes of sediment storage and erosion regulate shoreline movement and therefore, where coastal wetlands develop, setting up subsurface areas of preserved organic matter, blue carbon.
