A modelling approach to estimate carbon fluxes and standing stocks within seagrass meadows
Marine ecosystems play a crucial role in climate regulation by sequestering atmospheric carbon dioxide (CO2) in large reservoirs (biomass, deep-ocean and sediments) collectively termed Blue Carbon (BC). Coastal Blue Carbon (CBC) ecosystems (macrophytes and allied sediments) store a significant amount of carbon which otherwise would accumulate into the ocean-atmosphere system, potentially exacerbating climate change. Consequently, any alteration in the functioning of these ecosystems might lead to a release of previously stored carbon that, if not appropriately considered, could humper the achievement of climate neutrality. In line with EU priorities on biodiversity conservation and climate action, we developed a numerical model to quantify extant and future carbon fluxes mediated by seagrass meadows, the most significant coastal BC ecosystem in Europe. This report presents the conceptual basis of the model, the mathematical formulation and a global sensitivity analysis to estimate propagation of parameter uncertainty in the model output.
