Device and method for correcting seismic data for variable air-water interface

A computing device for seismic exploration, the computing device comprising:

• an interface configured to receive
• recorded seismic data d acquired by seismic sensors detecting a seismic signal S emerging from a surveyed subsurface, wherein the recorded seismic data includes pressure and/or particle motion traces,
• a position of a seismic source emitting the seismic signal S for an emission time interval, and
• an air-water interface datum that varies in time and space above the seismic source during the emission time interval;
• and
• a processor connected to the interface and configured to transform the recorded seismic data d using the position of the seismic source and the air-water interface datum thereby obtaining transformed seismic data;
• and
• generate an image of the surveyed subsurface, based on the transformed seismic data, wherein the image is indicative of various layers of the surveyed subsurface and enables determining presence of natural resources.

A non-transitory computer readable medium including computer executable instructions, wherein the instructions, when executed by a processor, implement instructions determining the processor to:

• receive recorded seismic data d acquired by seismic sensors detecting a seismic signal S emerging from a surveyed subsurface, wherein the recorded seismic data includes pressure and/or particle motion traces,
• receive a position of a seismic source emitting the seismic signal S for an emission time interval, and an air-water interface datum that varies in time and space above the seismic source during the emission time interval,
• transform the recorded seismic data d using the position of the seismic source and the air-water interface datum thereby obtaining transformed seismic data, and
• generate an image of the surveyed subsurface, based on the transformed seismic data,
• wherein the image is indicative of various layers of the surveyed subsurface and enables determining presence of natural resources.
