Abstract
In some implementations, airborne electromagnetic (AEM) data and seismic data for a geographic region including sand dunes are received, and the AEM data identifies apparent resistivity as a function of depth within the sand dunes. An inversion with cross-domain regularization is calculated of the AEM data and the seismic data to generate a velocity-depth model, and the velocity depth model identifies velocity variations within the sand dunes. A seismic image using the velocity-depth model is generated.

A method, comprising:
- receiving airborne electromagnetic (AEM) data and seismic data for a geographic region including sand dunes, wherein the AEM data identifies apparent resistivity as a function of depth within the sand dunes;
- calculating an inversion with cross-domain regularization of the AEM data and the seismic data to generate a velocity-depth model, wherein the velocity depth model identifies velocity variations within the sand dunes;
- and
- generating a seismic image using the velocity-depth model.
An apparatus, comprising:
- one or more processors;
- and
- a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instruct the one or more processors to:
- receive airborne electromagnetic (AEM) data and seismic data for a geographic region including sand dunes, wherein the AEM data identifies apparent resistivity as a function of depth within the sand dunes;
- calculate an inversion with cross-domain regularization of the AEM data and the seismic data to generate a velocity-depth model, wherein the velocity depth model identifies velocity variations within the sand dunes;
- and
- generate a seismic image using the velocity-depth model.
A non-transitory computer readable medium storing instructions to cause one or more processors to perform operations comprising:
- receiving airborne electromagnetic (AEM) data and seismic data for a geographic region including sand dunes, wherein the AEM data identifies apparent resistivity as a function of depth within the sand dunes;
- calculating an inversion with cross-domain regularization of the AEM data and the seismic data to generate a velocity-depth model, wherein the velocity depth model identifies velocity variations within the sand dunes;
- and
- generating a seismic image using the velocity-depth model.
