Abstract:
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.
