Selenium and stable isotopes of carbon and nitrogen in the benthic clam Corbula amurensis from Northern San Francisco Bay, California: May 1995-February 2010 [More info]: Monthly selenium concentration in this keystone species shows strong spatial and seasonal variation in a five-year series of analyses.
The chronology for the d18O record from Devils Hole, Nevada, extended into the Mid-Holocene [More info]: This study extends the oxygen isotope record of this important paleoclimate record forward in time to cover more recent history, up to 4,500 years before present.
The U.S. Geological Survey's TRIGA reactor [More info]: USGS operates a low-enriched uranium-fueled, pool-type reactor located at the Denver Federal Center. We use it for analyses of fissile and fissionable isotopes, geochemical analysis, and geochronology.
