Trace Metals in San Francisco Bay Clams
The clams Potamocorbula amurensis and Corbicula fluminea were collected at a variety of sites in the San Francisco Bay/ Delta beginning July 1990 and ending February 2010. These invasive species were used as biosentinels of the fate, transport, and effects of trace metals in the San Francisco Bay ecosystem.
San Francisco Bay Benthic Macroinvertebrate Atlas
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. To request this database, please contact Dr. Susan De La Cruz (sdelacruz@usgs.gov)
Bottom-Dwelling (Benthic) Invertebrates
In addition to studying birds and fish, the USGS monitors benthic (bottom dwelling) invertebrate communities (crustaceans, worms, and bivalves, including invasive clams) in the Bay-Delta.
