Seabed seismic source apparatus
First Claim
1. A seabed seismic source apparatus, comprising:
- a control module adapted for deployment at a seabed, the control module having a receiver which receives a remote signal and a firing controller which generates a firing signal in response to the remote signal;
at least one seismoacoustic source module adapted for deployment at the seabed with the control module, the seismoacoustic source module having a seismoacoustic source which generates a seismic signal and a firing device which fires the seismoacoustic source to generate the seismic signal;
a transmission link wherein signals travel through a body of water between the firing controller and the firing device, wherein the firing device fires the seismoacoustic source upon receiving the firing signal through the transmission link; and
means for determining a travel time of the firing signal through the water.

Abstract
A seabed seismic source apparatus includes a control module adapted for deployment at a seabed. The control module has a receiver for receiving a remote signal and a firing controller for generating a firing signal in response to the remote signal. The seabed seismic source apparatus further includes at least one seismoacoustic source module adapted for deployment at the seabed with the control module. The seismoacoustic source module has a seismoacoustic source for generating a seismic signal and a firing device for firing the seismoacoustic source to generate the seismic signal. The seabed seismic source apparatus further includes a transmission link between the firing controller and the firing device, wherein the firing device fires the seismoacoustic source upon receiving the firing signal generated by the firing controller.
