The Biogeochemistry (BGC) Group uses an interdisciplinary approach to address surface water quality issues and food web dynamics throughout California, particularly in the Sacramento-San Joaquin Delta and San Francisco Bay.
The BGC Group specializes in the application of in-situ optical sensors that monitor short- and long-term water quality trends. These sensors measure a host of biogeochemical parameters and capture continuous temporal trends – including those that may go undetected through traditional discrete sampling. The BGC Group also employs novel high-resolution boat-based mapping surveys, conducting intensive sampling for a diverse variety of biogeochemical parameters throughout the Bay-Delta.
These studies and data will help resource managers assess response to management actions and predict how the Bay-Delta will respond to future changes. The high frequency, real-time data can act as an early warning system for unanticipated, short-lived, or rapidly changing conditions, such as those due to spills, harmful algal blooms, and altered water-quality resulting from storms or levee breaches. The BGC group additionally specialize in the creation of novel data dissemination techniques in effort to ease open data acquisition, ultimately aiming to advance Bay-Delta science.

Delta Survey Data Visualization Contents for 2018 and 2020
Data visualization tool created for California's Bay-Delta Regional Monitoring Program. This web applicaton visualizes nutrients and phytoplankton spatially and temporally.
A data visualizatoin exploring the relationship between nutrient distribution and phytoplankton under different conditions across the San Francisco Delta and Estuary. Assessing distribution and abundance aids understanding of how managing nutrient supplies affects aquatic food webs, helping managers evaluate the potential environmental benefits of future nutrient reduction efforts against costs.
