The technology to recover natural gas depends on undisclosed types and amounts of toxic chemicals. A list of 944 products containing 632 chemicals used during natural gas operations was compiled. Literature searches were conducted to determine potential health effects of the 353 chemicals identified by Chemical Abstract Service (CAS) numbers. More than 75% of the chemicals could affect the skin, eyes, and other sensory organs, and the respiratory and gastrointestinal systems. Approximately 40-50% could affect the brain/nervous system, immune and cardiovascular systems, and the kidneys; 37% could affect the endocrine system; and 25% could cause cancer and mutations. These results indicate that many chemicals used...
Why did nuclear energy policies in France, Sweden, and the United States, very similar at the time of the oil crisis of 1973 and 1974, diverge so greatly in the following years? In answering this question, James Jasper challenges one of the most popular trends in political analysis: explanations relying exclusively on political and economic structures to account for public policies. Jasper proposes a new cultural and state-centered approach--one heeding not only structural factors but cultural meanings, individual biographies, and elite discretion. Surveying the period from the successful commercialization of light-water-reactor technology in the early 1960s to the present, he explains the events that occurred after...
This paper approximates the emissions rebound effects' associated with substituting expensive and GHG emitting natural gas (LNG) power plants, with apparently cheaper and lower emitting nuclear plant. It then evaluates the effect this has on economy wide electricity use as well as net GHG emissions changes. The analysis is undertaken by combining aspects of an input-output model with an optimizing energy systems model. The scope of the case study is limited to the effects of the electricity sector (and its emissions) on the Korean economy from 2005 to 2030. Its primary basis (in terms of data and assumptions) is the recent national Basic Plan for Long-Term Electricity Supply and Demand (KPX, 2006).(2) The cases...
Hydrates in nature have been known for a long time. In the last couple of decades the possibility of commercial utilization of natural hydrates has arisen as an alternative energy source. This paper asks 21 questions that, in the author’s opinion, need to be addressed and answered correctly before one can be confident one understands the scope of the problem one is facing in attempting to address the role of natural hydrates, both commercially and geologically.
To better understand large-scale interactions between fresh and saline groundwater beneath an Atlantic coastal estuary, an offshore drilling and sampling study was performed in a large barrier-bounded lagoon, Chincoteague Bay, Maryland, USA. Groundwater that was significantly fresher than overlying bay water was found in shallow plumes up to 8 m thick extending more than 1700 m offshore. Groundwater saltier than bay surface water was found locally beneath the lagoon and the barrier island, indicating recharge by saline water concentrated by evaporation prior to infiltration. Steep salinity and nutrient gradients occur within a few meters of the sediment surface in most locations studied, with buried peats and estuarine...

In 1967 and 1968 the USGS, in partnership with NASA and the National Park Service, extracted rock core from 13 locations in Yellowstone National Park. Depths of the holes ranged from 215 ft to 1,088 ft and the total drilled footage was 6,802 ft. The deepest hole was drilled in Norris Basin. Research on these cores provided critical understanding of complex geothermal systems that would inform the potential development of other systems, external to the park, as energy sources. These cores are extremely rare due to the many restrictions on sampling in the park. Years later, the cores were used to investigate the origin of some of Yellowstone supervolcano’s lavas using techniques that did not even exist when the cores...

This map shows the subcrop pattern of the Mesozoic rock units present at the top Mesozoic unconformity (also commonly referred to as the base Tertiary unconformity) in Cook Inlet basin, Alaska. The subcrop is projected onto the top Mesozoic unconformity depth surface of Cook Inlet basin, Alaska, published by Shellenbaum and others (2010). Publicly available geologic and geophysical data from multiple sources were collected, interpreted, and integrated into the subcrop map. Formation picks at the top Mesozoic unconformity were determined for 109 wells. Mesozoic horizons from two regional marine two-dimensional (2-D) seismic datasets (approximately 3,300 miles) were interpreted. Eight map units were established for...

Our mission is to provide , timely, reliable, impartial scientific information to our local, state, tribal, and federal partners so they can efficiently manage the water resources within their jurisdictions. Our data and research also help to protect the citizens of Idaho against floods, droughts, and other natural hydrologic hazards. Our science focuses on four basic areas of data collection and research: Surface water resources including rivers, lakes, and reservoirs Groundwater resources, both cold water and geothermal Water quality Water use and availability

Mitigation of ecological damage caused by rangeland wildfires has historically been an issue restricted to the western United States. It has focused on conservation of ecosystem function through reducing soil erosion and spread of invasive plants. Effectiveness of mitigation treatments has been debated recently. We searched for literature on postfire seeding of rangelands worldwide. Literature databases searched included SCOPUS, Dissertation Abstracts, Forest Science, Tree search, Web of Science, Google Scholar, and science.gov. Search terms within publications included fire or wildfire in combination with seeding, rehabilitation, restoration, revegetation, stabilization, chaining, disking, drilling, invasives,...

This Raw Data File provides lithologic descriptions of core fragments recovered from a series of core holes drilled by Exxon (mid-80s) in the uplands bordering the Yukon Flats basin. In addition to descriptions of the material, the tabulated file includes geographic location, core hole numbers, an age estimate, core fragment depth, general lithology, grain size, and facies interpretation. The author examined these core materials in Fairbanks during winter and spring 2002. This work was done in preparation for an assessment carried out by the U.S. Geological Survey of undiscovered, technically recoverable hydrocarbon resources in the Yukon Flats basin.

Post-fire rehabilitation seeding in the U.S. Intermountain West, primarily conducted by the Bureau of Land Management, is designed to reduce the risk of erosion and weed invasion while increasing desirable plant cover. Seeding effectiveness is typically monitored for three years following treatment, after which a closeout report is prepared. We evaluated 220 third-year closeout reports describing 214 aerial and 113 drill seedings implemented after wildfires from 2001 through 2006. Each treatment was assigned a qualitative success rating of good, fair, poor, or failure based on information in the reports. Seeding success varied by both treatment (aerial or drill) and year. Aerial seedings were rated 13.6% good, 18.3%...
