Effects of Bottom Topography on Ocean General Circulation
The long-range objective of the P.I. is to understand the motion of deep waters throughout the abyssal basins of the world ocean, both along the boundaries and over the abyssal plains. The zeroth-order theory of the spread of the deep water was presented in a classical paper by Stommel and Arons (19...
