This data release provides access to a low-altitude, aeromagnetic survey of a part of south-central Washington centered approximately 30 km east of Yakima and referred to as the Hanford aeromagnetic survey. The survey includes the city of Richland, numerous smaller communities, and the Hanford Site (https://www.hanford.gov). The Hanford aeromagnetic survey extends from the Columbia Plateau westward to the Cascade Range and illuminates magnetic anomalies associated with folds and faults of the Yakima folds, including the Toppenish Ridge, Ahtanum Ridge, Umtanum Ridge, Boyleston Mountain, Rattlesnake Mountain, Saddle Mountains, and Frenchman Hills anticlines. These data were acquired during September and October, 2009,...
This paper aims to provide a better understanding of the current situation of natural resources consumption in the world and its relationship with the level of social development. The Ecological Footprint concept is used to indicate human beings' environmental impact, and the Human Development Index (HDI) is used as a process for the social development level. Based on the dataset of 136 countries from the World Wildlife Fund (WWF), we calculate the Gini coefficients of the total Ecological Footprint per person (EF) and its sub items, i.e., Renewable Resources Footprint per person (REF) and Energy Footprint per person (EEF). The results indicate that significant inequality exists in natural resources consumption...
Metals contamination from mining activities is a persistent problem affecting aquatic ecosystems throughout mining districts in the western USA. The Gold Creek drainage in northern Idaho has a history of mining within its headwaters and contains elevated sediment concentrations of As, Cd, Cu, Pb, and Zn. To determine system-wide impacts of increased metals, we measured concentrations of metals in water, sediment, and benthic macroinvertebrate tissues and related them to whole-body fish tissues and histopathological alterations in native salmonids. Water concentrations were higher than those in reference areas, but were below water quality criteria for protection of aquatic biota for most of the study area. Sediment...

In the 300 Area of a U(VI)-contaminated aquifer at Hanford, Washington, USA, inorganic carbon and major cations, which have large impacts on U(VI) transport, change on an hourly and seasonal basis near the Columbia River. Batch and column experiments were conducted to investigate the factors controlling U(VI) adsorption/desorption by changing chemical conditions over time. Low alkalinity and low Ca concentrations (Columbia River water) enhanced adsorption and reduced aqueous concentrations. Conversely, high alkalinity and high Ca concentrations (Hanford groundwater) reduced adsorption and increased aqueous concentrations of U(VI). An equilibrium surface complexation model calibrated using laboratory batch experiments...

The ability of selenium (Se) to moderate mercury (Hg) toxicity is well established in the literature. Mercury exposures that might otherwise produce toxic effects are counteracted by Se, particularly when Se:Hg molar ratios approach or exceed 1. We analyzed whole body Se and Hg concentrations in 468 fish representing 40 species from 137 sites across 12 western U.S. states. The fish samples were evaluated relative to a published wildlife protective Hg threshold (0.1 Delta *mg Hg.g-1 wet wt.), the current tissue based methylmercury (MeHg) water quality criterion (WQC) for the protection of humans (0.3 Delta *mg Hg.g-1 wet wt.) and to presumed protections against Hg toxicity when Se:Hg molar ratios are >1. A large...

Environmental surveillance on and around the Hanford Site, located in southeastern Washington State, is conducted by the Pacific Northwest National Laboratory, which is operated by Battelle for the U.S. Department of Energy. These data collected provide a historical record of radionuclide and radiation levels attributable to natural causes, worldwide fallout, and Hanford Site operations. Data were also collected to monitor several chemicals and metals in Columbia River water, sediment, and wildlife. For more information regarding the 2006 sampling schedule for the Surface Environmental Surveillance Project and Drinking Water Monitoring Project, refer to Hanford Site Environmental Surveillance Master Sampling Schedule...

The most important problems facing wildlife conservation are the growing human population and its affluence, and the concomitant requirement for resources to accommodate this growth. A pressing question is how to maintain wildlife numbers and diversity when prime wildlife habitat is needed for agriculture, resource extraction, or urban expansion. Solutions to this problem may not be forthcoming because mainstream (generally meaning neoclassical) economic logic and policies are often in direct conflict with the goals of wildlife science. There is a great need for wildlife scientists to broaden their view and sophistication of economics and also to expand the wildlife field to encompass the larger social forces that...
[[Abstract ]Human induced climate change is one of the single most significant indicators that human society is not pursuing a sustainable trajectory. Managing the risks requires a major transformation of the way energy needs are met. Such a transformation includes changes in the production and consumption system and the incentive structure that shapes this system. The major driving force for transformation is the public concern about the environmental impact of the present fossil fuel based energy system. We may expect that energy producers, encouraged by governments, NGOs and consumer preferences will be responding to these concerns and expectations sooner or later. In fact a number of major international energy...
