A method and apparatus is disclosed for performing a seismic survey below the
surface
of a body of water and on the seabed. In one embodiment, a plurality of seismic
data receivers are removably loaded in a carrier located above the surface of the
water and the carrier is lowered into the water and placed at a depth relatively
close to the seabed. Each of the receivers has a memory for recording the vibrations
of the seabed and has a switch for activating the memory. A ROV is used to unload
the receivers from the carrier and to deposit each receiver on the seabed and along
a survey line. In one embodiment, the receivers comprise a frame, a pressure vessel
for housing the memory and remotely activated controls, and a geophone that is
separately planted into the seabed at a relatively short distance from the frame.
