Abstract
Seismic exploration techniques and the seismic imaging of subsurface layers, particularly apparatus for seismic exploration near the seafloor, are disclosed. The apparatus enables controlled-depth towing of detectors to be carried out a short distance above the seafloor. The apparatus includes a streamer depth controller and at least one altitude keeper device, attached at intervals along the length of a towed streamer. The streamer carries detectors for measuring, for example, P- and S-waves in the seafloor.
