This paper estimates the extra costs of drilling for oil and gas on federal land as compared to private land in the Wyoming Checkerboard. The Checkerboard is a center of U.S. oil and gas activity in which square-mile sections of property alternate between federal and private ownership as originally established by the Pacific Railway Acts of 1862 and 1864. This land ownership pattern is used as an experimental control that may be used to identify differences in drilling cost on federal and private land. Estimates presented suggest that average drilling costs per well are about $200,000 higher on federal property than on private property. This difference is attributed to more stringent enforcement of environmental...
The Aquatic Core Networks, Unstratified is comprised of unstratified versions of Lotic Core Areas and Lentic Core Areas. These datasets are one of two versions of aquatic core areas that are part of a suite of products from Nature’s Network (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. Although the stratified version “Aquatic Core Networks” is considered by the planning team to be the primary version for users, this unstratified version is also made available for reference and use.These and other datasets that augment or complement the Aquatic...
The Rail Network is a comprehensive database of the nation's railway system at the 1:100,000 scale. The data set covers all 50 States plus the District of Columbia.
The Rail Network is a comprehensive database of the nation's railway system at the 1:100,000scale or better. The data set covers all 50 States plus the District of Columbia. These data were reprojected to USA_Contiguous_Albers_Equal_Area_Conic_USGS_version and clipped to the MAR REA boundary.
We are seeking to better understand networks among resource managers with respect to developing plans for climate change adaptation. We are pursuing this through a network analysis based on a survey of federal resource management staff and scientists in the southwestern and Midwestern U.S. Originally planned, this study was conceived to cover the Southwest and North Central Climate Science Centers, as defined by the USGS. In practice, surveys are most easily distributed within regions as defined by the federal resource agencies. Unfortunately, there is no uniform set of regions. We have tried to be comprehensive in our survey and cover at least the North Central and Southwestern Region.

Integrated Data Management Network for LCCs and Partners: A Framework for Coordinated Data Discovery, Access, Analysis, Visualization, Project Tracking and Coordination
Landscape Conservation Cooperatives (LCCs) have a critical need for information management processes that facilitate science product (i.e., data, analysis and decision tools, documents) sharing; data storage, security, and dissemination; and project tracking, communication and collaboration tools (Arctic LCC 2010, North Atlantic LCC 2011, Southern Rockies LCC 2011, California LCC 2011). LCCs and their partners are already developing and using a wide variety of data management systems to address LCC and project needs, but the LCC Network and all partners need better coordination across these efforts to develop and share common standards and services, improving the intellectual exchange needed to achieve the LCC mission....
Microbiological transformation of Mn and Fe in surface and subsurface waters in the zones of influence of water intakes
Addressing energy poverty rather than energy equity conveniently evades the problem of the gap in energy consumption per capita in the developed and developing world. For energy security policies to adequately address energy poverty it requires a widening of scope from national to global. This is a comment to the forthcoming presentation of IEA's proposition for a new architecture for financing universal modern energy access to be presented at the conference ‘Energy for all—Financing access for the poor’ held in Oslo in October 2011.

The National Highway Planning Network is a comprehensive network database of the nation's major highway system. It consists of the nation's highways comprised of Rural Arterials, Urban Principal Arterials and all National Highway System routes. The data set covers the States of Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming . The nominal scale of the data set is 1:100,000 with a maximal positional error of ±80 meters.
These two datasets represent a normalized least-cost corridor mosaic (see WHCWG 2010 and McRae and Kavanagh 2011) calculated using (1) temperature gradients and a landscape integrity resistance raster, or (2) temperature gradients only, following the climate gradient linkage-modeling methods outlined in Nuñez (2011), using an adapted version of the Linkage Mapper software (McRae and Kavanagh 2011). This GIS dataset is one of several climate connectivity analyses produced by Tristan Nuñez for a Master's thesis (Nuñez 2011). The dataset was produced in part to assist the Climate Change Subgroup of the Washington Wildlife Habitat Connectivity Working Group (WHCWG). The core areas in the map lie in Washington State...
The comid field of these data can be used to join to the NHDPlus version 2 flowline comid or catchment featureid attributes. The included attributes follow the same data model as the NHDPlusV2 but include numerous updates and improvements to network connectivity. All attributes that depend on network connectivity have been recalculated. These attributes are based on the National Hydrography Dataset Plus V2.1 (NHDPlusV2) network geometry and modifications retrieved from the National Water Model V2.1 (NWMv2.1) and "E2NHDPlusV2_us: Database of Ancillary Hydrologic Attributes and Modified Routing for NHDPlus Version 2.1 Flowlines" (E2NHDPlusV2) datasets. These attributes are available in three formats: csv, fst, and...
