Research Abstract
Due to global warming, natural disasters have occurred worldwide, underscoring the urgent need for climate change mitigation. Much of the earth’s carbon is captured and stored naturally as “blue carbon” in oceanic and coastal ecosystems with submerged aquatic vegetation (SAV). SAV enhances the water column stratification, suppressing vertical water exchange in shallow water areas. When stratification occurs, large amounts of carbon can be stored in the deeper layers of an aquatic ecosystem because water column stratification prevents carbon flux between the surface and lower layers. To accurately represent carbon flows in these models, the mechanisms by which SAV suppress vertical mixing and CO2 flux from the vegetation canopy need to be considered. We successfully developed numerical models, which enable us to accurately evaluate the effect of respiration and photosynthesis on carbon for freshwater lakes and coastal ecosystems using laboratory experiments and field observations.
