AMS has been actively engaged in supporting dischargers, regulatory agencies, and the research community in interpreting the effects of recent changes in nutrient dynamics in the Suisun Bay-Delta on phytoplankton growth and ecosystem health. As part of our efforts, Dr. Mine Berg has supported development of a conceptual model on nutrients in the Bay-Delta, participated in a working group investigating the issue, and received grant funding, in collaboration with co-PI Dr. Raphael Kudela of the University of California at Santa Cruz, from the Interagency Ecological Program to further investigate nutrient dynamics.
