San Francisco Bay Benthic Macroinvertebrate Atlas

Benthic Atlas Project Image.


Information on benthic macroinvertebrate populations is currently available from numerous agencies in disparate databases.  To maximize the value of these data, San Francisco State University and the U. S. Geological Survey have combined data from several of these sources into a single comprehensive database. This gives managers a tool to easily extract species or biomass information from these data according to spatial and temporal queries.  We included macroinvertebrate abundance, biomass and distribution information collected from the benthic zone of the San Francisco Bay.  All macroinvertebrate data have been stored as tables inside a geodatabase and tied to spatial locations via relationship classes.  Benthic Macroinvertebrate data were contributed by the following organizations:

  • USGS National Research Program (1988-2009)
  • USGS WERC San Francisco Bay Estuary Field Station (2003-2005)
  • California Department of Water Resources (1990, 1993, 1995)
  • University of Wyoming (1999-2000)
  • San Francisco Estuary Institute (1975-2006) compilation includes data from:
    • National Oceanic and Atmospheric Administration (2000-2001)
    • California Department of Water Resources (1975-2006)
    • Bay Area Dischargers Association (1994-1997)
    • Bay Protection and Toxic Cleanup Program (1992, 1997)
    • SFEI Regional Monitoring Program (1994-2003)
    • SFEI Coastal Intensive Sites Network (2000-2001)
  • California Academy of Science Institute of Zoology data (1903-2005)
