Most of the motion in the ocean can be understood in terms of Newton’s Law that the acceleration of a parcel of water (how fast its velocity changes with time – du/dt) is related to the sum of forces acting on that parcel of water. We can split the forces, velocities and accelerations into south-nor ...
