Abstract

Disclosed are apparatus and methods for streamer positioning during marine seismic exploration. In one embodiment, a designated location for each of one or more transponders is determined based on a survey area, and each transponder is anchored to a sea floor at its own designated location. A marine seismic survey is then performed over the survey area with a marine-towed seismic sensor array, where multiple transceivers are moved along with the seismic sensor array during the marine seismic survey. Signals are communicated between the plurality of transceivers and each transponder so as to determine positions of the plurality of transceivers. Other embodiments, aspects, and features are also disclosed.
