Surface drifters (Figure 1, right) were used to characterize the large-scale flow features in several open water areas within Suisun Bay and the Sacramento-San Joaquin Delta. Each of the drifter studies presented in this poster provides a snapshot (1/2 tidal cycle ~ 6 hour) characterization of the primary flow paths, the tidal excursion, and the dispersion characteristics for each of the study areas. These data were specifically collected to:
- determine the primary flow paths in Suisun Bay and Sherman Lake to help position long-term (~ 3 month) fixed-location data collection equipment,
- qualitatively estimate the magnitude of tidal pumping between the Sacramento and San Joaquin Rivers, and
- qualitatively measure the difference between spring and neap residence times in flooded islands.
