Abstract
A method and device for seismic exploration of an underwater subsurface zone using seismic receivers coupled with the bottom of the water mass. Acquisition units ( ) comprising a spire ( ) where seismic receivers ( ) are arranged, a measuring compartment ( ) for acquisition and storage of the data received by the receivers, as well as removable and selective floating devices ( ) are used. The acquisition units ( ) are launched and, under the effect of gravity, they attach to the bottom and couple the receivers with the underlying formations. The respective positions thereof are first detected, seismic acquisition operations are carried out using an underwater source so as to collect seismic data on the formation, then the floating devices ( ) are actuated so as to bring all or part of acquisition units ( ) back up to the surface or a data collection device (vehicle or passive collection unit) is lowered to the neighbourhood of the various units.
