Three-dimensional acoustic imaging of the temporal evolution of internal wave fields in the Gulf of Mexico
Authorea Preprints, 2022•authorea.com
We report the observation of internal wave fields evolving at the continental slope in the
northern Gulf of Mexico using oil-industry three-dimensional (3D) seismic imaging
techniques. High-resolution seismic images reveal dynamic wave fields actively present in
the 600-900 m water column. The spectral analysis of these wave fields shows that these
waves possess a slope that represents the characteristics of internal waves. Further
analyses suggest that these internal wave fields are most likely generated by a nearby …

We report the observation of internal wave fields evolving at the continental slope in the northern Gulf of Mexico using oil-industry three-dimensional (3D) seismic imaging techniques. High-resolution seismic images reveal dynamic wave fields actively present in the 600-900 m water column. The spectral analysis of these wave fields shows that these waves possess a slope that represents the characteristics of internal waves. Further analyses suggest that these internal wave fields are most likely generated by a nearby cyclonic eddy and its interaction with the continental slope. This work demonstrates that oil-exploration 3D seismic data, if appropriately analyzed, are a useful and powerful dataset for studying the temporal evolution of deep ocean dynamics that would otherwise be impossible at similar vertical and lateral resolution.
