EML Databases and Sample Archives ** Please note that all of the programs discussed here and on pages linked from here have been terminated and the information presented is out of date. EML is no longer the custodian of the physical sample archives listed in these databases. For information on where these samples have been relocated, please contact: webmaster@eml.st.dhs.gov ** Taking sediment cores in Alaska. EML provides access to comprehensive computer databases of published data from its current and historic environmental programs. EML maintains an extensive library of samples associated with its research programs, in some cases going back well over 40 years. Sample types in the archive include: human bone, animal tissue and bone, vegetation, milk and food ash, soil, lake water and sediment, seawater and aerosol filters. Over 70,000 samples, including filters obtained from altitudes ranging from sea level to high in the stratosphere, are presently in this archive. We are in the process of placing these sample inventories on-line. See EML's Global Sampling Network Factsheet (PDF) for an overview of the sampling program, and EML-300 for a thorough description of current sampling procedures. The Environmental Sample Archive and Internet Database Factsheet (PDF) and Technical Notes about the databases are also available. Please read the disclaimer before making use of any of the data presented herein. EML Environmental Databases: Surface Air Sampling Program: Radioactivity measurements from 1957-present (air filter samples maintained at EML) Global Fallout Deposition program: 90Sr and other isotope measurements from 1954-present (resin samples maintained at EML) Soil Sampling Database: Soil samples collected from 1953 to present (air dried and pulverized soil samples maintained at EML) Lake Sediment samples: Sediment cores and grab samples collected from 1979 to 1991 (freeze-dried and pulverized sediments are maintained at EML) High-Altitude Sampling Program: Radioactivity and trace gas measurements from 1957-1983 (air filter and gas samples maintained at EML) Project ASHCAN (balloon) high-altitude radioactivity measurements from 1957-1983 Project STARDUST (aircraft) high-altitude radioactivity measurements from 1957-1967 Project AIRSTREAM (aircraft) high-altitude radioactivity measurements from 1967-1983 Atmospheric Radon Measurements at Mauna Loa and Bermuda Diet samples: Food samples collected in three U.S. cities and other locations from 1960-1991 Bone samples: Bone samples collected in four U.S. cities from 1961-1988 Other Databases: At DOE's Carbon Dioxide Information Analysis Center (CDIAC) at Oak Ridge National Laboratory. TRACDAB: a database of stratospheric trace gases collected during Project Airstream. RANDAB: a database of the world's largest compilation of stratospheric and upper-tropospheric radionuclide data.

For more information about EML's sample databases, contact: webmaster@eml.st.dhs.gov The EML Sample Archives makes available environmental radiological data collected for programs funded through the U.S. Atomic Energy Commission, the U. S. Energy Research and Development Administration and the U. S. Department of Energy. All of these programs have been terminated. The databases were last updated in 1999. No additional data will be added to these databases. Any inquiries about these programs should be made to webmaster@eml.st.dhs.gov.
