A wave pressure spectrum can be calculated from correlated surface displacement and pressure records. The frequency domain is then separated into high and low domains by a critical frequency, above which surface displacement cannot be calculated from the corresponding pressure spectrum by linear wave theory but rather, by equilibrium range theory.

The small fraction (~30%) of Landsat's multispectral scanner data containing oceanic information was separated from the total radiance under clear sky and stable conditions, converted logarithmically to concentration of suspended particles in seawater, and compared to ground truth.

Fluid Mech.. 106:299-329 Presented is a rather personal view of the ~mportant developments in double-diffusive convection, a subject whose evolution has resulted from close interaction among theoreticians, laboratory experimenters and sea-going oceanographers. Some general conclusions are drawn. Further progress will depend on a close collaboration between fluid dynamicists and other scientists. Dept. of Applied Math., Silver St., Cambridge CB3 9EW.
