From an observational point of view, determining the ocean circulation and its changes through time, presents a formidable problem owing to the fundamental physical difficulties (electromagnetic opacity, high pressures, Etc.) and the resulting extremely short instrumental record of even marginal global-scale adequacy. Understanding what can be inferred about oceanic changes in heat content, regional and global sea level, flow changes, et al., in a system with a wide-range of memory, becomes an interesting problem of observations, kinematical and dynamical modelling, random walks,and sometimes fantastical assumptions.
