For my undergraduate dissertation project, I conducted a literature review aiming to calculate “The Climate Impact of Salt Marsh Realignment” and so investigate the efficacy of these ecosystems as climate change mitigators. I compared rates of carbon sequestration with rates of methane and nitrous oxide flux. The results showed fluxes of other greenhouse gases can detract somewhat from carbon sequestration and so reduce the net benefit the of the realignment process. Furthermore, this project was the beginning of my interest in blue carbon which led to my pursing a subsequent MSc by research degree and continuing to work in this field.
My MSc project was entitled “Climate Impact of a UK Salt Marsh: 20th century sea-level change, carbon storage and greenhouse gas flux” and involved using the three distinct but connected elements listed to investigate the functioning of a natural salt marsh. This project exemplifies the possibility of using interdisciplinary techniques to build a comprehensive picture of the impact a particular ecosystem has on climate change and vice versa. This project cemented my interest in blue carbon and led to further questions about the functioning of realigned sites compared with their natural counterparts.
