Daily Delta Outflow Index (from California Department
of Water Resources) for 1997 (upper panel) and the
changing distribution of surface salinity along
the USGS transect (lower panel). Intensity of
shading is proportional to salinity, with darker
shadings indicating higher salinities. The vertical
axis represents variability in space, from the lower
Sacramento River (top of figure) to Central Bay
(at kilometer 0) and then to the lower South Bay
(bottom of vertical axis). The horizontal axis represents
variability in time, matched to the flow-variability
above. The thick solid line shows the changing position
of the location where surface salinity was 2 psu.
Small diamonds show the locations of USGS measurements
that coincided with the three RMP samplings of 1997
(see Table 3.4). |
