Marissa Wulff
Marissa Wulff is a Biologist at the California Water Science Center.
Marissa Bauer Wulff is a biologist with the U.S. Geological Survey’s California Water Science Center, where she researches and assists in projects relating to aquatic biology and ecology. Marissa has been involved in ecosystem modeling for the Sacramento-San Joaquin Delta as well as flow-regime and aquatic mercury studies. Marissa is currently involved in research looking at the effects of climate change on selected fish species of the San Francisco Bay-Delta.
