Research Objectives
A decision support system (DSS) is under development within
ESD as part of a CALFED-sponsored project to assist in management
of episodes of low-dissolved-oxygen concentrations in the San Joaquin
River (SJR) Deep-Water Ship Channel (DWSC). Biodegrading algae and
organic sediments that settle in the DWSC remove oxygen from the
water column. When dissolved oxygen concentrations dip below 5 mg/L,
conditions adverse to the survival of juvenile salmon arise. ESD’s
science role in this project to date has been to develop an understanding
of the relative algal contributions made by agriculture and managed
seasonal wetlands, the fate of this algae in transit along the SJR,
and its impact on dissolved oxygen in the DWSC.
