About this map
The January to April seasonal salinity gradient is plotted in the SF Estuary
beneath the annual average CPUE of age-1 pacific herring 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 January to April seasonal salinity gradient is plotted in the SF Estuary
beneath the annual average CPUE of age-1 pacific herring 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.
