The California Environmental Data Exchange Network (CEDEN) is a system designed to facilitate the integration and sharing of data collected by many different participants involved in the water and environmental resources of the State of California.

SFEI is one of four Regional Data Centers and provides data management services and data visualization and integration tools to the geographic region of the San Francisco Bay-Delta
and its watersheds.

The CEDEN website and data access tool was released to the public in August 2010. At that time, only water and sediment data were available for downloading. Now tissue monitoring data are also available through CEDEN's tool. SFEI manages several large tissue datasets from various projects that are available through CEDEN, including the RMP (triennial sportfish data from 1997-2009, and effects and exposure bird data from 2002-2007), Fish Mercury Project (fish data from the Bay-Delta watershed from 2005-2007), SWAMP (historic bioaccumulation data generated under three historic State Board programs and other major studies from 1970-2005), and Coastal Fish Contamination Program (fish and shellfish from 1998-2003).

and analysis tools, and data integration.
