Montage illustration. A montage to illustrate the appearance of primary plume at crest of upwelling (0907 UT), the structuring of the west wall of upwelling (0927 UT), the development of secondary plumes (0958, 1027 UT), and the relative displacement of the primary plume to the eastern edge of the upwelling (1027 UT). Colored curves in the center panel represent the nominal locations of the primary plume and the upwelling, at different times on the night of 24 July 1979. All six of the backscatter maps are shown in Tsunoda (1983).
