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 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.
