The invention concerns a device for emitting seismic waves designed to operate by being towed by a vessel, characterized in that it comprises means capable of discharging compressed air under high pressure into water, to generate a bubble (44) of a general annular shape.
Claims20
A device for emitting seismic waves into water, the device comprising:
- a support structure;
- and
- plural air sources attached to the support structure and configured for discharging compressed air under high pressure into water, the plural air sources being arranged on the support structure to have an annular geometry to generate a resulting bubble of a general annular shape while an air source of the plural air sources generates a spherical bubble.
A method for emitting seismic waves, the method comprising:
- arranging plural air sources on a support structure to have an annular geometry;
- and
- discharging from the plural air sources compressed air under high pressure into water to generate a resulting bubble of a general annular shape,
- wherein an air source generates a spherical bubble.
