A topography with similar scales in both the downstream and the cross-stream directions is potentially more relevant to geophysical problems.
Evolution might have proceeded faster had these geophysical processes been faster.
It is clear that many geophysical and geochemical events have occurred during this large time period.
The same property also applies to the circulation of the atmosphere, and it is one of the most prominent features of geophysical fluid dynamics.
Turbulence in stratified media is a phenomenon common t o a variety of geophysical and engineering situations.
This gives a barotropic shear problem which seems more relevant to geophysical fluid dynamics than the classical shear problems.
Offshore areas are now covered using data available from airborne and shipborne geophysical surveys, although the quality of the coverage is variable.
In a geophysical context this can be considered a study of the response of a continuously stratified ocean to wind-stress forcing at the surface.
