The Southwest Biological Science Center, Arizona Water Science Center, and Western Geographic Science Center have teamed up to bring you informative & interesting news about USGS science & related activities in the southwest U.S. — and (if we say so ourselves) often beautiful imagery associated with our science on the @USGSAZ Twitter account.

There are 5 Science Centers located on the FSC: the Arizona Water Science Center, the Astrogeology Science Center, the Geology, Minerals, Energy, and Geophysics Science Center, the Southwest Biological Science Center, and the Western Geographic Science Center.

The Southwest Biological Science Center (SBSC) is based in Flagstaff, AZ, with field stations in Tucson, AZ, and Moab, UT.  SBSC's social media highlights terrestrial and river ecosystem science conducted on the Colorado Plateau, Colorado River, and drylands of Arizona, California, and Utah. SBSC's mission is to conduct quality, objective research on the lands and aquatic systems of the Southwest. This research can assist those who manage, conserve, and rehabilitate the arid regions of the nation.

The Arizona Water Science Center (AzWSC) is based in Tucson, AZ, with field stations in Flagstaff, Glendale, and Yuma, AZ. AzWSC’s social media highlights science conducted in water systems across Arizona. The mission of the AzWSC is to collect and interpret high quality, impartial scientific information to provide resource managers and the public with the knowledge required to understand and manage the critical resources of Arizona and the Southwest. Key capabilities include water use, streamflow monitoring, microgravity-based hydrologic analysis, surface geophysics, water-quality monitoring, continuous slope area, uncrewed aircraft systems, groundwater-surface water interaction modeling.

The USGS Western Region campus in Menlo Park, California houses many different USGS teams, such as Western Geographic Science Center, Pacific Coastal and Marine Science Center, Water Science Center, and Volcano Science Center, and features many state-of-the-art laboratories.




Western Geographic Science Center (WGSC) is based in Menlo Park, CA, with field stations in Tucson and Flagstaff, AZ. WGSC's social media highlights its mission to conduct geographic research on the environmental and societal consequences of a changing landscape, including water availability and sustainability, climate change, landscape change, and natural hazards and society. WGSC's tools and models help decision makers use complex scientific information to understand their alternative options.
