Recently, the importance of a water resource is highly concerned. But ocean is not a safe place and hard to approach. Therefore, there is a need to approach from a distance. For this reason, Underwater Wireless Sensor Networks (UASNs) technologies are used and vigorously studied for wireless monitoring underwater environment. The UASNs gather various underwater environmental data that should be delivered to a Monitoring Center - need the information.-where nearby or far from UASNs are deployed. To deliver data form underwater to the Monitoring Center or vice versa, a gateway should change acoustic signal to RF or CDMA, WiFi, and so on. Depends on the service requirement, the surface gateway can adopt various wireless communication channels such as Cellular network, Zigbee, and so on. In this paper, we propose the architecture of surface gateway that has several wireless communication channels and communication protocol.
