Dynamic features of coastal waters can be detected and monitored in sequential photography by 1 pattern interpretation, 2 simple comparative analyses, 3 matching of positive-negative pairs, and 4 comparative densitometry. Procedures for densitometric analyses of temporal changes are given. Application of the procedures is demonstrated by analyses of tones representing suspended sediment and plankton in the James estuary and lower Chesapeake Bay. Field and photographic studies revealed four types of water color boundaries that form either in local convergence zones of secondary currents or where water masses of different origin meet. Color changes were partly due to sediment concentration differences and were sometimes manifest by microplankton community changes, but the relationships are complex and variable. Author
