[ACG40-01] Submarine groundwater discharge from Mt. Fuji in Suruga Bay(Ⅵ)
Keywords:submarine groundwater discharge (SGD), Mt. Fuji, remotely operated vehicle (ROV), water sampling method
For the purpose of contribution to make sense of the rich coastal ecosystem in Suruga Bay, we conducted a survey for submarine groundwater discharge (SGD) in Oku-Suruga Bay: from the mouth of the Fuji River, at which the fault is found, to Tagonoura, where the lavas of the Younger Fuji volcano are distributed from 100 to 200 m below sea level. We detected SGD in the top of the cliff in the west of Tagonoura usinga remotelyoperatedvehicle(ROV), sampled seawater containing a high percentage of sea bottom spring water and conducted water quality analyses. In this presentation, we introduce our works noted above.
