About this map
The February to June seasonal salinity gradient is plotted in the SF Estuary
beneath the annual average CPUE of delta smelt (total population) for
each monitoring station in the SF Bay Study mid-water trawl, consistent
with the salinity-abundance relationship published in Kimmerer
(2002), Marine Ecology and Progress Series 243: 39-55.

About this map
The February to June seasonal salinity gradient is plotted in the SF Estuary
beneath the annual average CPUE of delta smelt (total population) for
each monitoring station in the SF Bay Study mid-water trawl, consistent
with the salinity-abundance relationship published in Kimmerer
(2002), Marine Ecology and Progress Series 243: 39-55.
