Scientific field of study pertaining to the physics of the oceanic crust and ocean-inundated continental crust. Variables include marine morphological features, geophysical processes of the marine environment,
and geophysical measurements of the marine environment.
Marine geophysics is the scientific discipline that employs methods of geophysics to study the world's ocean basins and continental margins, particularly the solid earth beneath the ocean. It shares objectives with marine geology, which uses sedimentological, paleontological, and geochemical methods. Marine geophysical data analyses led to the theories of seafloor spreading and plate tectonics.
