In order to clarify the effect of the buffer action of current by the eelgrass (Zosteria marina L.) and the mechanism of independence formation of eelgrass bed by the advection of the seed, we carried out the fixed point observation and tracking of the current drogue for Lagragian current measurement at the coast of Ohtabu and Kakui Island in the Seto Inland Sea, Okayama Prefecture from July to November, 2005. The results showed that the current pattern was very complex in eelgrass bed and remarkable characteristic was not. Therefore, we carried out the hydraulic experiment to clarify in detail though the buffer action was confirmed by our field measurement. According to the experiment results, it was shown that the eelgrass decreased the current enough. The advection of water mass with seeds in natural eelgrass bed by tidal current played an important role in eelgrass bed formation around the Ohtabu Island because the current drogue drifted from the natural eelgrass bed in Ohtabu Island at about 3km by our Lagragian current measurement.
