The carbon sequestered in coastal vegetated systems (e.g. seagrass meadows) was termed “Blue Carbon” and has recently been highlighted as an option for climate change mitigation initiatives. However, relationships between air-sea CO<sub>2</sub> flux and environmental factors, varying tidally and diurnally, remained unclear. In this study, 48-hours continuous in situ measurements were performed in the <i>Zostera</i> meadow at Hashirimizu, Yokosuka. We statistically analyzed the observed data using the structured equation modeling (SEM). Specifically, we implemented the path analysis. The results indicate that wind speed was a direct factor for determining the flux, and the community metabolism (e.g. ecosystem production and respiration) was an indirect but important factor.
