Carl Bowin and Dan McKenzie analysed ship-track gravity and bathymetry across the Atlantic. Treating the profiles spectrally lets a transfer relation predict part of the gravity signal from seafloor relief.^[ref]

Residual gravity highlights structures not accounted for by the fitted topographic contribution. Its interpretation still requires assumptions about subsurface density and support.

Dan McKenzie and Carl Bowin used the spectral relation between Atlantic bathymetry and gravity to investigate how seafloor loads are supported. The method separates a topography-correlated signal from residual structure.^[ref]

The wavelength dependence is useful because shallow loads, compensation and lithospheric flexure contribute differently across spatial scales. A single gravity anomaly does not isolate those contributions.
