A Spatially Integrated Dissolved Inorganic Carbon (SiDIC) Model for Aquatic Ecosystems Considering Submerged Vegetation

Abstract

Extreme weather events and natural disasters have occurred worldwide due to global warming, underscoring the urgent necessity of climate change mitigation (IPCC, 2014, 2018, 2021). Nellemann et al. (2009 have shown that much of the Earth's carbon is captured and stored naturally as "blue carbon" in oceanic and coastal ecosystems, with vegetated habitats, such as mangroves and submerged aquatic vegetation (SAV), accounting for more than 50% of all carbon storage in ocean sediment. Previous studies have shown that SAV enhances the stratification

Carbon dioxide uptake in a eutrophic stratified reservoir: Freshwater carbon sequestration potential

“…Regarding the DIC uptake by SAVs, a DIC equation was proposed by Nakayama et al (2020a) [ 6 ]; to understand the effect of Zostera Marina on DIC sequestration in Komuke Lagoon [ [39] , [40] , [41] , [42] ]. In contrast, Nagatomo et al (2023) [ 43 ]; proposed a DIC equation for Potamogeton crispus in Australia's freshwater lake, Lake Monger. They found that P. crispus has a higher potential to capture DIC than Z. marina .…”
