Abstract: A disclosed survey method includes towing geophysical survey streamers in a body of water and using sensors within the streamer to collect measurements that are then conveyed along the streamer to a recording station using at least one wireless transmission link. In some implementations at least one sensor is coupled to a wireless transceiver in a streamer to transmit geophysical survey measurement data along the streamer to a wireless base station. The base station receives the wirelessly transmitted seismic data and communicates it to a central recording station. Each segment of the streamer may contain a base station to collect wireless data from the sensors in that segment, and each base station may be coupled to the central recording station by wiring (e.g., copper or fiber optic). Other implementations employ ranges of sensors wired to local transceivers that form a peer-to-peer wireless network for communicating data to the central recording station.
