Introduction to Nuclear Power
To provide the power for a dynamo-electric machine, or electric generator, nuclear power plants rely on the process of nuclear fission. In this process, the nucleus of a heavy element, such as uranium, splits when bombarded by a free neutron in a nuclear reactor.(1) The fission process for uranium atoms yields two smaller atoms, one [...]

- Why aren't we drilling in the Bakken Formation?Oil has been produced from the Bakken Formation since the 1950’s. Please see our slideshow presentation for context at http://energy.usgs.gov/flash/Bakken_slideshow.swf. The USGS does not maintain statistics on oil production, however, this information can be obtained from publicly available sources like the North Dakota Department of Mineral Resources […]
- How do I access the online USGS Publications Warehouse?The USGS Publications Warehouse (http://pubs.usgs.gov/) has released a new interface and a variety of new content and features. The new version of this tool now includes citations for USGS-authored content including journal articles, books, book chapters, proceedings, and other research written by USGS staff but published commercially. […]
- What is National Land Imaging?NLI is a concept that places a single agency in charge of future civil operational land remote sensing satellite acquisition, operation, and data management. These three functions have been separated historically and assigned to several different agencies. Currently, DOI performs two of them – operations and data management. With NLI comes a broad responsi […]

- Climate Change Implicated in Decline of Horseshoe CrabsLEETOWN, W. Va. — A distinct decline in horseshoe crab numbers has occurred that parallels climate change associated with the end of the last Ice Age, according to a study that used genomics to assess historical trends in population sizes. The new research also indicates that horseshoe crabs numbers may continue to decline in the future because of predi […]
- An island's rebirth: Life emerges after a catastrophic volcanic eruptionAnchorage, Alaska — A secluded island in the Aleutian chain is revealing secrets of how land and marine ecosystems react to and recover from a catastrophic volcanic eruption that appeared at first glance to destroy all life on the island. Yet little by little – a wingless beetle here, a tuft of grass there, Kasatochi, an island in the Alaska Maritime Nat […]
- Glaciers Retreating in AsiaMany of Asia’s glaciers are retreating as a result of climate change. This retreat impacts water supplies to millions of people, increases the likelihood of outburst floods that threaten life and property in nearby areas, and contributes to sea-level rise. The U.S. Geological Survey, in collaboration with 39 international scientists, published a report on […]
