Abstract
To investigate the diurnal changes of water CO2 fugacity in urbanized shallow waters, we performed in situ measurements throughout the day in both summer and winter in Hiragata Bay located in Yokohama. We statistically analyzed the observed data set using the structured equation modeling (SEM) and the path analysis. As a result, we found that the diurnal variation in the fugacity of CO2 was largely affected by the TA and DIC changes that are moderated mainly by urban drainage and biological metabolism.
