Optically stimulated luminescence (OSL) dating is increasingly used to estimate the age of fluvial deposits. A significant limitation, however, has been that conventional techniques of sampling and dose rate estimation are suitable only for thick (>60 cm) layers consisting of sand size or finer grains. Application of OSL dating to deposits lacking such layers remains a significant challenge. Alluvial fans along the western front of the Lost River Range in east-central Idaho, USA are one example. Deposits are typically pebble to cobble sheetflood gravels with a sandy matrix but thin to absent sand lenses. As a result, the majority of ...


The Spatial Cross-Correlation Method For Dispersive Surface Waves, Andrew P. Lamb, Kasper van Wijk, Lee M. Liberty, T. Dylan Mikesell 2014 Boise State University

The Spatial Cross-Correlation Method For Dispersive Surface Waves, Andrew P. Lamb, Kasper Van Wijk, Lee M. Liberty, T. Dylan Mikesell

Geosciences Faculty Publications and Presentations

Dispersive surface waves are routinely used to estimate the subsurface shear-wave velocity distribution, at all length scales. In the well-known Spatial Autocorrelation method, dispersion information is gained from the correlation of seismic noise signals recorded on the vertical (or radial) components. We demonstrate practical advantages of including the cross-correlation between radial and vertical components of the wavefield in a spatial cross-correlation method. The addition of cross-correlation information increases the resolution and robustness of the phase velocity dispersion information, as demonstrated in numerical simulations and a near-surface field study with active seismic sources, where our method confirms the presence of a ...


Fossil Baramins On Noah's Ark: The "Amphibians", Marcus R. Ross 2014 Liberty University

Fossil Baramins On Noah's Ark: The "Amphibians", Marcus R. Ross

Marcus R. Ross

Here I provide a compendium of extinct “amphibian” groups, representatives of which may have been carried aboard Noah’s Ark. Following previous work by the Ark Encounter team, I selected the taxonomic rank of family as a first-order proxy for the biblical “kind.” The resulting tabulation places 54 extinct “amphibian” families/kinds on board the Ark. While this number hinges upon taxonomies built upon fossil data (and its inherent shortcomings compared to extant forms), it serves as a reasonable approximation of the number of fossil “amphibians” taken aboard the Ark. When added to previously determined kinds of extant anurans, caudates ...

Speleothem And Biofilm Formation In A Granite/Dolerite Cave, Northern Sweden, Therese Sallstedt, Magnus Ivarsson, Johannes Lundberg, Rabbe Sjöberg, Juan Ramón Vidal Romaní 2014 University of South Florida

Speleothem And Biofilm Formation In A Granite/Dolerite Cave, Northern Sweden, Therese Sallstedt, Magnus Ivarsson, Johannes Lundberg, Rabbe Sjöberg, Juan Ramón Vidal Romaní

International Journal of Speleology

Tjuv-Antes grotta (Tjuv-Ante's Cave) located in northern Sweden is a round-abraded sea cave ('tunnel cave'), about 30 m in length, formed by rock-water abrasion in a dolerite dyke in granite gneiss. Abundant speleothems are restricted to the inner, mafic parts of the cave and absent on granite parts. The speleothems are of two types: cylindrical (coralloid, popcorn-like), and flowstone (thin crusts). Coralloids correspond to terrestrial stromatolite speleothems in which layers of light calcite alternate with dark, silica-rich laminae. The dark laminae are also enriched in carbon and contain incorporated remains of microorganisms. Two types of microbial communities can be ...


Caves In Caves: Evolution Of Post-Depositional Macroholes In Stalagmites, Nurit Shtober-Zisu, Henry P. Schwarcz, Tom Chow, Christopher R. Omelon, Gordon Southam 2014 University of South Florida

Caves In Caves: Evolution Of Post-Depositional Macroholes In Stalagmites, Nurit Shtober-Zisu, Henry P. Schwarcz, Tom Chow, Christopher R. Omelon, Gordon Southam

International Journal of Speleology

In a previous paper (Shtober-Zisu et al., 2012) we described millimeter to centime-sized fluid-free holes within the interiors of stalagmites of widely varying origin. We present here further observations of this phenomenon, using X-ray tomography, macroscopic and microscopic observation of sections of twenty-six stalagmites from various sites in North America and the Caribbean region. We can distinguish three types of cavities in speleothems: primary µm-sized fluid inclusions; mm to cm sized holes, aligned along the stalagmite growth axis which are clearly syngenetic; and µm to cm-sized holes away from the growth axis (“off-axis holes or OAHs”) deeply buried inside their ...


Postglacial Early Permian (Late Sakmarian– Early Artinskian) Shallow-Marine Carbonate Deposition Along A 2000 Km Transect From Timor To West Australia, Vladimir I. Davydov 2014 Boise State University

Postglacial Early Permian (Late Sakmarian– Early Artinskian) Shallow-Marine Carbonate Deposition Along A 2000 Km Transect From Timor To West Australia, Vladimir I. Davydov

Geosciences Faculty Publications and Presentations

Late Sakmarian to early Artinskian (Early Permian) carbonate deposition was widespread in the marine intracratonic rift basins that extended into the interior of Eastern Gondwana from Timor in the north to the northern Perth Basin in the south. These basins spanned about 20° of paleolatitude (approximately 35°S to 55°S). This study describes the type section of the Maubisse Limestone in Timor-Leste, and compares this unit with carbonate sections in the Canning Basin (Nura Nura Member of the Poole Sandstone), the Southern Carnarvon Basin (Callytharra Formation) and the northern Perth Basin (Fossil Cliff Member of the Holmwood Shale). The ...


Discovery Of Shallow-Marine Biofacies Conodonts In A Bioherm Within The Carboniferous-Permian Transition In The Omalon Massif, Ne Russia Near The North Paleo-Pole: Correlation With A Warming Spike In The Southern Hemisphere, Vladimir I. Davydov, Alexander S. Biakov 2014 Boise State University

Discovery Of Shallow-Marine Biofacies Conodonts In A Bioherm Within The Carboniferous-Permian Transition In The Omalon Massif, Ne Russia Near The North Paleo-Pole: Correlation With A Warming Spike In The Southern Hemisphere, Vladimir I. Davydov, Alexander S. Biakov

Geosciences Faculty Publications and Presentations

The conodont genera Hindeodus and Streptognathodus are reported for the first time within the Carboniferous-Permian transition in the northern high latitudes of the Paren’ River, Omolon Massif, NE Russia. Several fossil groups, including brachiopods, bivalves, scaphopods and microgastropods were found to be prolific in the invertebrate-dominated bioherms. These bioherms occur within predominantly siliciclastic sequences with extremely poor fauna, whereas in the studied bioherms the diversity of the bivalves and brachiopods exceeded observed diversity elsewhere in coeval facies in NE Russia. The bioherms are biostratigraphically constrained as uppermost Pennsylvanian to lowermost Cisuralian based on ammonoids. The very unusual peak of bivalve ...


The Development Of L-Tectonites In High-Strain Zone Settings: A Multiscale Modeling Investigation, Weiyin Chen 2014 Western University

The Development Of L-Tectonites In High-Strain Zone Settings: A Multiscale Modeling Investigation, Weiyin Chen

University of Western Ontario - Electronic Thesis and Dissertation Repository

Shape fabrics in high-strain zones are commonly used to constrain deformation processes in the lithosphere. Linear fabric, as a type of shape fabric, usually indicates constrictional strain and is an important feature in orogenic belts. Among all kinds of linear fabrics, the isolated L-tectonites, which are surrounded by strong planar fabrics, are poorly understood. The isolated L-tectonites are generally developed in heterogeneous high-strain zones. Their formation involves heterogeneous and multiscale deformation processes that current single-scale kinematic models cannot explain. To relate isolated L-tectonites in a high-strain zone with its boundary conditions, I apply a multiscale approach. Isolated L-tectonites are regarded ...


Fluid Properties In The Formation Of High-Grade Iron Ore In Northern Minnesota, Elizabeth Drommerhausen 2014 Minnesota State University, Mankato

Fluid Properties In The Formation Of High-Grade Iron Ore In Northern Minnesota, Elizabeth Drommerhausen

Journal of Undergraduate Research at Minnesota State University, Mankato

The Mesabi Iron Range in Northern Minnesota has been a major producer of iron ore for over 100 years. Production has been from the 1.85 – billion-year –old Biwabik Iron Formation, an iron-rich sedimentary rock that is tilted gently to the south. Most of the known high-grade ore lies near the surface and has been already mined. Determining whether more high-grade ore may lie at depth could have significant economic impact on the mining industry in northern Minnesota. To evaluate the likelihood of finding more high-grade iron ore deeper underground, it is important to determine the source of the fluids ...

Calibrating Water Depths Of Ordovician Communities: Ecological Controls On Depositional Gradients In Upper Ordovician Strata Of Southern Ohio And North-Central Kentucky, Usa, Carlton E. Brett, Thomas J. Malgieri, James R. Thomka, Christopher D. Aucoin, Benjamin F. Dattilo, Cameron A. Schwalback

Geosciences Faculty Presentations

Limestone and shale facies of the Grant Lake Formation (Upper Ordovician; Katian; Maysvillian) are well exposed in the Cincinnati Arch of southern Ohio and north central Kentucky, and highly fossiliferous. These rocks also document gradual change in lithofacies and biofacies from offshore, nodular, phosphatic, brachiopod-rich limestones and marls to very shallow olive gray platy, laminated dolostones with desiccation cracks and sparse ostracodes, southward along a gently sloping ramp. This study uses facies analysis in outcrop to determine paleoenvironmental parameters, particularly those related to water depth (e.g., position of the photic zone and shoreline, and environmental energy). Within tightly a ...


Silica Distribution In Oxidized Biwabik Iron Formation: Ore-Waste Cutoff Prediction, Ryan Rague 2014 Minnesota State University, Mankato

Silica Distribution In Oxidized Biwabik Iron Formation: Ore-Waste Cutoff Prediction, Ryan Rague

Journal of Undergraduate Research at Minnesota State University, Mankato

Oxidation of iron formation in the Mesabi Iron Range, Minnesota, has negatively impacted recovery of the main ore mineral, magnetite, by two mechanisms. First, magnetite has been partially or completely oxidized to hematite (martite), which is not magnetically separable. Second, silica has been remobilized during the oxidation process, and comprises a higher percentage of the ore concentrate than is desirable due to its altered grain size, making it difficult to grind sufficiently. Fluid inclusion data showed that fault-channeled, diagenesis-stage fluids (mean T homog = 154° C; mean salinity = 9.5 wt% NaCl equivalent) were responsible for early oxidation of iron formation ...


Uncovering The Influence Of Household Sociodemographic And Behavioral Characteristics On Summer Water Consumption In The Portland Metropolitan Area, Chang-yu Hong, Heejun Chang 2014 University of Wisconsin Milwaukee

Uncovering The Influence Of Household Sociodemographic And Behavioral Characteristics On Summer Water Consumption In The Portland Metropolitan Area, Chang-Yu Hong, Heejun Chang

International Journal of Geospatial and Environmental Research

As urban areas continue to expand, sustainable urban water resource management has become an important issue in green and sustainable city planning. Using single-family residential (SFR) household survey, we identified the determinants of household summer daily water consumption from 2000 to 2005 in Portland, Oregon. The multiple regression results show that approximately 41% of variations in SFR water consumption is explained by average building size, household attitude to water conservation, community engagement of household, and presence of native plants in the garden. The multi-level modeling results show that household attitude to water conservation is an important predictor of SFR water ...


Assessing The Impacts Of Climate Change, Urbanization, And Filter Strips On Water Quality Using Swat, Mike Psaris, Heejun Chang 2014 University of Wisconsin Milwaukee

Assessing The Impacts Of Climate Change, Urbanization, And Filter Strips On Water Quality Using Swat, Mike Psaris, Heejun Chang

International Journal of Geospatial and Environmental Research

Precipitation changes and urban growth are two factors altering the state of water quality. Changes in precipitation will alter the amount and timing of flows, and the corresponding sediment and nutrient dynamics. Meanwhile, densification associated with urban growth will create more impervious surfaces which will alter sediment and nutrient loadings. Land and water managers rely on models to develop possible future scenarios and devise management responses to these projected changes. We use the Soil and Water Assessment Tool (SWAT) to assess potential changes in stream flow, sediment, and nutrient loads in two urbanizing watersheds in Northwest Oregon, USA. We evaluate ...


Automated Image Interpretation For Science Autonomy In Robotic Planetary Exploration, Raymond Francis 2014 Western University

Automated Image Interpretation For Science Autonomy In Robotic Planetary Exploration, Raymond Francis

University of Western Ontario - Electronic Thesis and Dissertation Repository

Advances in the capabilities of robotic planetary exploration missions have increased the wealth of scientific data they produce, presenting challenges for mission science and operations imposed by the limits of interplanetary radio communications. These data budget pressures can be relieved by increased robotic autonomy, both for onboard operations tasks and for decision- making in response to science data.

This thesis presents new techniques in automated image interpretation for natural scenes of relevance to planetary science and exploration, and elaborates autonomy scenarios under which they could be used to extend the reach and performance of exploration missions on planetary surfaces.

Infiltration And Runoff Parameters For Tilled And No-Till Row Crops, Andrew J. Volkmer 2014 University of Nebraska - Lincoln

Infiltration And Runoff Parameters For Tilled And No-Till Row Crops, Andrew J. Volkmer

Biological Systems Engineering--Dissertations, Theses, and Student Research

Infiltration and runoff are hydrologic processes that effect the amount of water available to plants, for groundwater recharge, and for stream flow. No-till planting (NT) is a management practice used to reduce soil erosion, increase water infiltration, and reduce soil water evaporation, and can have great impact on infiltration and runoff. An investigation was conducted to determine the impact of NT on infiltration and runoff when compared to tilled conditions.

Runoff and precipitation data was gathered from sites at Fillmore County, NE, Phelps County, NE, the USDA-ARS North Appalachian Experimental Watersheds (NAEW) near Coshocton, OH, and the Lennoxville Research Station ...


A Comparative Study Of Underwater Robot Path Planning Algorithms For Adaptive Sampling In A Network Of Sensors, Sreeja Banerjee 2014 University of Nebraska - Lincoln

A Comparative Study Of Underwater Robot Path Planning Algorithms For Adaptive Sampling In A Network Of Sensors, Sreeja Banerjee

Computer Science and Engineering: Theses, Dissertations, and Student Research

Monitoring lakes, rivers, and oceans is critical to improving our understanding of complex large-scale ecosystems. We introduce a method of underwater monitoring using semi-mobile underwater sensor networks and mobile underwater robots in this thesis. The underwater robots can move freely in all dimension while the sensor nodes are anchored to the bottom of the water column and can move only up and down along the depth of the water column. We develop three different algorithms to optimize the path of the underwater robot and the positions of the sensors to improve the overall quality of sensing of an area of ...
