From page 23...
... An appropriate statistical description of ocean circulation includes two main parts. One is the statistics of the velocity field, and the other is the statistical description of the transport mechanisms.

... . In particular, comparing diffusivity maps and maps of mean flow or velocity variance provides a way to test simple theories of turbulence, and eventually indicates how to improve them.

From page 25...
... Stationarity can be relaxed fairly realistically provided the ocean is characterized by slowly varying fluctuations so that time averages, even though not constant, are representative of the particular ocean climate present during the measurements. Inhomogeneity could in principle be reduced inside each box by increasing the resolution, i.e., by decreasing L, the scale of the boxes.
