True polar wander (TPW) occurs because the Earth’s spin axis remains always very nearly aligned with its axis of maximum non-hydrostatic moment of inertia—the short axis of the non-hydrostatic ...

A study of water velocities near subtidal kelp fronds, relative to the motion of the kelp itself, is described. The dynamic model developed by Utter and Denny (1996) is used to develop a quantitative ...
