Origin of faults, fissures and volcanic vent alignments at a structural triple junction, Newberry Volcano, central Oregon

Creator:: Grasso, Kyla A., Meigs, Andrew, and Cladouhos, Trenton T.
Abstract:: Newberry Volcano in central Oregon formed at the intersection of extensional fault systems defining the Basin and Range extensional province, the Cascades Graben and the Brothers Fault Zone. A unique structural orientation characterizes each fault system. Basin and Range faults trend north, northeast and northwest. The Cascade Graben is defined...

Benthic foraminiferal stable isotope stratigraphy of Site 846 : 0-1.8 Ma

Creator:: Mix, Alan C., Le, J., and Shackleton, N. J.
Abstract:: A stable-isotope stratigraphy at Site 846 (tropical Pacific, 3°06'S, 90°49'W, 3307 m water depth), based on the benthic foraminifers Cibicides wuellerstorfi and Uvigerina peregrina, yields a high-resolution record of deep-sea δ¹⁸O and δ¹³C over the past 1.8 Ma, with an average sampling interval of 3 k.y. Variance in the δ¹⁸O...

Dissolved organic carbon in interstitial waters from sediments of Middle Valley, leg 139

Creator:: Ran, Baiyun and Simoneit, Bernd R. T.
Abstract:: High-temperature combustion oxidation measurements of nonvolatile dissolved organic carbon (DOC) have been determined for pore waters from sediments of Middle Valley, Ocean Drilling Program Leg 139, as well as for overlying and near-bottom seawater. The DOC values in the interstitial waters are generally greater than those in the overlying water...

Millennial–scale CaCO₃ and C[subscript ORG] events along the northern and central California margins : stratigraphy and origins

Creator:: Lyle, Mitchell, Mix, Alan C., Ravelo, A. Christina, Andreasen, Dyke, Heusser, Linda, and Olivarez, Annette
Abstract:: Sediments from five Leg 167 drill sites and three piston cores were analyzed for C[subscript ORG] and CaCO₃. Oxygen isotope stratigraphy on benthic foraminifers was used to assign age models to these sedimentary records. We find that the northern and central California margin is characterized by k.y.-scale events that can...

Thermogenic and bacterial hydrocarbon gases (free and sorbed) in Middle Valley, Juan De Fuca Ridge, Leg 139

Creator:: Whiticar, Michael J., Faber, Eckhard, Whelan, Jean K., and Simoneit, Bernd R. T.
Abstract:: The sorbed gases at all four Ocean Drilling Program Leg 139 sites (855, 856, 857, and 858) showed the unmistakable presence of thermogenic hydrocarbons. No indication of abiogenic gas was found. The evidence for the thermogenic hydrocarbons includes elevated contents of higher hydrocarbons (i.e., C₁/[C₂ + C₃] ca. 2-20), δ¹³CCH₄...

Lipid/bitumen maturation by hydrothermal activity in sediments of Middle Valley, leg 139

Creator:: Simoneit, Bernd R. T.
Abstract:: The accelerated diagenesis, maturation, and catagenesis of organic matter to hydrothermal petroleum was studied in sediments from Ocean Drilling Program Leg 139 in Middle Valley, northern Juan de Fuca Ridge. Sediments at Sites 855 and 856 have experienced high heat flow resulting in accelerated diagenesis of the immature organic matter...

Developmental neurobehavioral toxicity of bisphenol A in zebrafish (Danio rerio)

Creator:: Saili, Katerine Schletz
Abstract:: Billions of pounds of bisphenol A (BPA) are produced annually around the globe for the manufacture of numerous consumer products, including polycarbonate food and water containers, the protective resin linings of food cans, thermal printing paper, and dental fillings. BPA exposure during nervous system development has been associated with learning...

Bars, bumps, and holes : models for the generation of complex beach topography

Creator:: Holman, R. A. and Bowen, A. J.
Abstract:: In shallow water, any two waves of the same frequency are shown to produce complex patterns of drift velocity above the sea bed. If the longshore components λ₁, λ₂ of the wave numbers of the two waves are different, these steady flow patterns exhibit a longshore periodicity of wave number...

Abstract:: An Injury Prevention Program Designed to Reduce the Risk of Lower-Extremity Injuries within Women's NCAA Gymnastics Teams. Grounded in a behavior change perspective using an integrated theory model that combines the Health Belief Model and the Theory of Planned Behavior, the culmination of this project is a lower-extremity injury prevention...

Amplification and dampening of soil respiration by changes in temperature variability

Creator:: Sierra, C. A., Harmon, M. E., Thomann, E., Perakis, S. S., and Loescher, H. W.
Abstract:: Accelerated release of carbon from soils is one of the most important feedbacks related to anthropogenically induced climate change. Studies addressing the mechanisms for soil carbon release through organic matter decomposition have focused on the effect of changes in the average temperature, with little attention to changes in temperature variability....
