Land Cover trends
http://landcovertrends.usgs.gov/
Land Cover Trends is a research project focused on understanding the rates, trends, causes, and consequences of contemporary U.S. land use and land cover change. The research is supported by the Geographic Analysis and Monitoring Program of the U.S. Geological Survey (USGS) and is a collaborative effort with the U.S. Environmental Protection Agency (EPA) and the National Aeronautics and Space Administration (NASA).Land use and land cover change is a pervasive environmental phenomenon that modifies land cover characteristics and affects a broad range of socio-economic, biologic, geologic, and hydrologic systems and processes. Understanding the impacts of land use and land cover change and their associated feedbacks on environmental systems requires an understanding of the rates, patterns, and drivers of past, present, and future land use change.
San Francisquito Creek
http://geography.wr.usgs.gov/sfcreek
The San Francisquito Creek Web site aims to provide information and data to inform the public and decisionmakers about issues concerning the creek and the possible trade-offs that might be necessary in reaching mutually agreeable solutions to the complex problems. The primary goal of this Web site is to facilitate the dissemination of data and information from research, monitoring, and environmental-management activities concerning San Francisquito Creek. We hope to ensure that all interested users (such as scientists, engineers, resource managers, local and regional governmental agencies, developers, and the public) have quick and easy access to a wide range of digital data and general information. The San Francisquito Creek Project is a collaborative project between the U.S. Geological Survey (USGS) and other organizations to work on understanding the intermingled environmental and political issues. The USGS maintains this Web site and provides digital data and educational tools to facilitate the public's involvement in addressing issues of the creek and improving the decisionmaking processes.The Bay Area Regional Database
http://bard.wr.usgs.gov
BARD's goal is to provide USGS mapping data that is not readily available on other USGS data sites. These include historical maps for the Bay area, individual elevation (DEM) quadrangles (1:24,000 scale), and county compressed orthoimagery. Links to other USGS data such as bathymetry are also provided.Access USGS - San Francisco Bay and Delta
http://sfbay.wr.usgs.gov/
"Since the discovery of gold in the Sierra Nevada foothills in 1848, the SF Bay and Delta region has undergone rapid, large-scale, and permanent changes. To help understand the extent and impact of these changes, the USGS has maintained a broad program of multi-disciplinary research studies in the San Francisco Bay estuary and its watershed."Mercury and Decision Support in California
http://geography.wr.usgs.gov/science/mercury/index.html/
The Mercury and Decision Support in California (MADSIC) Web site provides general information and links to total-maximum-daily-load (TMDL) programs, market-based environmental programs, and the mercury scientific-research field in California.
