Plate 8.3 (a) Volume backscattering (color scale in decibels – red is more scattering,
blue is less) analysis at 48°N for particles reflecting sound from an acoustic Doppler
current profiler. Note the several combinations (one obvious, the others emphasized
by lines) of layering and layer movement with time of day. (b) Vertical particle
velocity from sound-frequency shift. Layers move rapidly near sunset (SS) and
sunrise (SR).
