Results 48 - 56 of 56 listed alphabetically [list by similarity]
PDF 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.
PDF The concept of geologic carbon sequestration [More info]
Explains securing carbon dioxide in deep geologic formations to prevent its release to the atmosphere and contribution to global warming as a greenhouse gas.
PDF The future of rare earth elements--will these high-tech industry elements continue in short supply? [More info]
Presentation describing uses of rare earth elements, why they are important, where they occur and are produced, and aspects of the economics of production and consumption with emphasis on sites that might be developed for production.
PDF The principal rare earth elements deposits of the United States-A summary of domestic deposits and a global perspective [More info]
Explains the geologic setting in which these deposits are found, with information about production and the processes used to extract these valuable mineral resources.
PDF Thermal Properties of Methane Gas Hydrates [More info]
This unusual form of hydrocarbons can alter the thermal properties of host sediments; the analysis presented here helps us understand how those sediments might behave under natural or human-induced changes in the environment.
PDF Tintina gold province study, Alaska and Yukon Territory, 2002-2007 [More info]
New discoveries and modernized extraction methods prompted renewed interest in gold deposits in this part of central Alaska, prompting a variety of studies described here.
PDF Trace metals related to historical iron smelting at Hopewell Furnace National Historic Site, Berks and Chester Counties, Pennsylvania [More info]
Iron ore containing elevated concentrations of trace metals was smelted here during 113 years of operation (1771-1883). We sampled a variety of materials nearby to determine the amount of metals such as arsenic, chromium, copper, lead, and zinc.
What Mobilizes Arsenic in Ground Water? [More info]
Research findings and examples of application to real problems--chemical reactions between nitrate, iron, and oxygen can affect the mobility of trace amounts of arsenic.
PDF Zinc-The key to preventing corrosion [More info]
Explains how we use zinc, where it comes from, and discusses worldwide supply and demand.
