Mineral resource of the month: iron oxide pigments
Water Resources Division, U.S. Geological Survey
2008, Earth (53) 25-25
The article discusses iron oxide pigments, which have been used as colorants since human began painting as they resist color change due to sunlight exposure, have good chemical resistance and are stable under normal ambient conditions. Cyprus, Italy and Spain are among the countries that are known for the production...

Joseph K. Gaydos, Leslie Dierauf, Grant Kirby, Deborah Brosnan, Kirsten Gilardi, Gary E. Davis
2008, EcoHealth (5) 460-471
Like other coastal zones around the world, the inland sea ecosystem of Washington (USA) and British Columbia (Canada), an area known as the Salish Sea, is changing under pressure from a growing human population, conversion of native forest and shoreline habitat to urban development, toxic contamination of sediments and species,...
Density currents in the Chicago River: Characterization, effects on water quality, and potential sources
P. Ryan Jackson, Carlos M. Garcia, Kevin A. Oberg, Kevin K. Johnson, Marcelo H. Garcia
2008, Science of the Total Environment (401) 130-143
Bidirectional flows in a river system can occur under stratified flow conditions and in addition to creating significant errors in discharge estimates, the upstream propagating currents are capable of transporting contaminants and affecting water quality. Detailed field observations of bidirectional flows were made in the Chicago River in Chicago, Illinois...
Discrimination of lichen genera and species using element concentrations
James P. Bennett
2008, Lichenologist (40) 135-151
The importance of organic chemistry in the classification of lichens is well established, but inorganic chemistry has been largely overlooked. Six lichen species were studied over a period of 23 years that were growing in 11 protected areas of the northern Great Lakes ecoregion, which were not greatly influenced by...

Long-term dynamics of leafy spurge (Euphorbia esula) and its biocontrol agent, flea beetles in the genus Aphthona
Diane L. Larson, James B. Grace, Jennifer L. Larson
2008, Biological Control (47) 250-256
Three flea beetle species (Aphthona spp.), first introduced into North America in 1988, have come to be regarded as effective biological control organisms for leafy spurge (Euphorbia esula). The black flea beetles (Aphthona lacertosa and A. czwalinae) in particular have been shown to cause reductions in leafy spurge stem counts...
Topographic mapping
Water Resources Division, U.S. Geological Survey
2008, Report
The U.S. Geological Survey (USGS) produced its first topographic map in 1879, the same year it was established. Today, more than 100 years and millions of map copies later, topographic mapping is still a central activity for the USGS. The topographic map remains an indispensable tool for government, science, industry,...
Slow journey home

Daniel R. Muhs, E. Arthur Bettis III, John N. Aleinikoff, John P. McGeehin, Jossh Beann, Gary Skipp, Brian D. Marshall, Helen M. Roberts, William C. Johnson, Rachel Benton
2008, GSA Bulletin (120) 1378-1407
Loess is one of the most extensive surficial geologic deposits in midcontinental North America, particularly in the central Great Plains region of Nebraska. Last-glacial-age loess (Peoria Loess) reaches its greatest known thickness in the world in this area. New stratigraphic, geochronologic, mineralogic, and geochemical data yield information about the age...

John N. Aleinikoff, Daniel R. Muhs, E. Arthur Bettis III, William C. Johnson, C. Mark Fanning, Rachel Benton
2008, GSA Bulletin (120) 1362-1377
Pb isotope compositions of detrital K-feldspars and U-Pb ages of detrital zircons are used as indicators for determining the sources of Peoria Loess deposited during the last glacial period (late Wisconsin, ca. 25–14 ka) in Nebraska and western Iowa. Our new data indicate that only loess adjacent to the Platte...
Molecular epidemiology of viral hemorrhagic septicemia virus in the Great Lakes region
James Winton, Gael Kurath, William Batts
2008, Fact Sheet 2008-3003
Viral hemorrhagic septicemia virus (VHSV) is considered by many nations and international organizations to be one of the most important viral pathogens of finfish (Office International des Epizooties 2007). For several decades following its initial characterization in the 1950s, VHSV was thought to be limited to Europe where it was...

2008, Canadian Field-Naturalist (122) 312-315
American White Pelicans (Pelecanus erythrorhynchos) are colonial nesters, making them susceptible to site-specific mortality factors. One of the largest known breeding colonies is at Chase Lake National Wildlife Refuge in North Dakota. In 2004, this colony suffered total reproductive failure. In 2005, we collected abandoned eggs from this colony to...
California Cenozoic Biostratigraphy -- Paleogene: Chapter 4 in Petroleum systems and geologic assessment of oil and gas in the San Joaquin Basin Province, California
Kristin McDougall
2008, Professional Paper 1713-4
The time transgressive nature of the California benthic foraminiferal stages is in most cases the result of poor taxonomy, use of local species ranges, and a lack of understanding about the type sections. Correcting these problems allows the stages to be consistently applied and enhances their ability to identify coeval...

2008, IHDP Update 46-52
The changes occurring in mountain regions are an epitome of climate change. The dramatic shrinkage of major glaciers over the past century – and especially in the last 30 years – is one of several iconic images that have come to symbolize climate change. Climate creates the context for ecosystems,...
An exploration of Bureau of Reclamation approaches for managing conflict over diverging science
Nina Burkardt, Emily Ruell, Douglas Clark
2008, Technical Memorandum 86-68211-09-01
As a major institutional agent supplying Western water resources, the Bureau of Reclamation (Reclamation) provides important leadership, technical, and financial resources in water management, serving as the West's "water broker" (Bowersox 2000; Pisani 2003). In recent years, growing numbers of constituencies using water and the over-allocation of water resources have...
