The Data Integration and Decision Support Core develops and maintains databases, mathematical and statistical analyses, and mechanisms to allow researchers and decision makers to visualize probable consequences of alternative mechanistic models and management alternatives.


As the name implies, the Data Integration and Decision Support Core has two primary functions: 1) to organize and manage data in ways that support advanced analysis and visualization, and 2) to make research results readily accessible and usable to a wide variety of clients, including environmental and regulatory agencies, conservation organizations, private industry, and the interested public. The Core obtains and converts major external data sets that range from water quality to satellite images, builds GIS coverages, and develops hydrodynamic transport models for toxics and organisms. Risk analysis algorithms developed by the Core can be applied widely to data from all Center projects. The Core also maintains the Center's GIS lab, World Wide Web site and Internet Services. The Core's faculty are principally responsible for coordinating Center data integration technology with EPA and other collaborating agencies.

Effective outreach requires both electronic and human elements. Core personnel have made several innovations in providing easier public access to databases and maps through the Center's Web server. It also develops curricula and methodologies to "train the trainers" to use Center and other governmentally funded information resources to help in local, regional, and national environmental problem solving. The current clientele includes University Extension and Cooperative Extension specialists and outreach experts from Resource Conservation Districts. The Core also provides opportunities for agency scientists, analysts, and planners to take "mini-sabbaticals" to work cooperatively with Center scientists.

Core faculty members serve on numerous agency and interagency advisory boards and committees, ranging from the science advisory for interagency research in the San Francisco Bay and Sacramento Delta through several endangered species recovery planning committees, to national data and metadata standards committees. In each of these cases, we were invited to serve on these committees in part to help convert Center research findings into public policy.

The emphasis of the Core is on processes at the organization levels of populations, communities, and ecosystems, and reaches into analyses at the level of entire regional landscapes. Processes examined at the individual level (e.g. the effects of rice field runoff on the development of striped bass larvae) provide inputs into population level models. Conversely, tissue-level biomarker data provide tests of exposure predicted by regional-scale transport models.

Expected Results:

The Core's methodological innovations are also widely applicable outside the Center's geographical regions. The hydrodynamic models have been adapted for use in several coastal rivers and the Salton Sea in Southern California. The time-series models of extinction risk have been applied to endangered fish species in the Gulf of California, and the biodiversity analyses are widely used throughout the National Park Service in the U.S. and UNESCO Man and the Biosphere (MAB) Reserves in North America, Central Europe, and Latin America.
