How does eutrophication affect the greenhouse gas balance in the salt marsh?

Salt marshes are fragile ecosystems known for their specific biodiversity and ability to store large amounts of carbon. This ability makes the salt marsh a buffer against global warming. Rising sea levels, higher temperatures and increased nutrient input can increase greenhouse gas emissions from these ecosystems, thus counteracting their beneficial effect. In the project, you will investigate whether eutrophication increases the release of greenhouse gases such as CO₂, CH₄ or N₂O from a Danish salt marsh.
