Innovations in Managing Western Water: New Approaches for Balancing Environmental, Social and Economic Outcomes (Martz Summer Conference, June 11-12)
Many aspects of western water allocation and management are the product of independent and uncoordinated actions, several occurring a century or more ago. However, in this modern era of water scarcity, it is increasingly acknowledged that more coordinated and deliberate decision-making is necessary for effectively balancing environmental, social, and economic objectives. In recent years, a variety of forums, processes, and tools have emerged to better manage the connections between regions, sectors, and publics linked by shared water systems. In this event, we explore the cutting edge efforts, the latest points of contention, and the opportunities for further progress.
Analysis And Comparison Of Physical Properties And Morphology Of Impact Melt Flows On Venus And The Moon To Determine Atmospheric Controls, Christine Elizabeth Dong
Impact melt flows form when target material melted by an impact breaches the rim of the impact crater. The melt flows out and away from the crater, forming a lava flow. Such flows have been identified on Venus and the Moon by previous studies. This study aims to document impact melt flows on these two bodies to determine the differences, if any, between them, and to ascertain whether these differences are due to atmospheric conditions. Previously recorded morphological data from Robert Herrick of the Lunar and Planetary Institute and Neish et al. (2014) are used in conjunction with S-band (12 ...
Deformation Post-Doming: New Mapping Of The Oliverian Jefferson Dome, Mt. Dartmouth 7.5' Quadrangle, New Hampshire, Michelle Devoe
The Mt. Dartmouth 7.5’ Quadrangle, west of the Presidential Range, contains the southeastern portion of the Jefferson Dome, the largest of the Oliverian Domes. As part of a USGS NHGS EdMap StateMap project, the purpose of this study was to remap this part of the Jefferson Dome and perform a structural and mineralogical analysis of its rock units to develop a better understanding of the tectonic history of the Northeast. Structural analyses show dextral shear zones and folded foliation which suggest at least three phases of deformation post-doming. Literature claims shear zones exist throughout the Northeast, and this analysis ...
Petrogenesis And Paleostress Analysis Of The Mesozoic Mill Brook Dike Zone In The Mount Dartmouth 7.5' Quadrangle, New Hampshire, Graham Grear Oxman
Field mapping linked with petrogenetic and brittle structural studies of Mesozoic basalt dikes was performed in the Mount Dartmouth 7.5' Quadrangle, adjacent to the Presidential Range, NH. This was done in hopes of creating a better understanding of the intrusion setting and brittle deformational history of the basalt dikes, particularly in relation to the regional tectonic context. Field work done during the summer of 2014 revealed a 100 meter wide, 7.8 km long zone containing multiple mafic dikes that are exceptionally well exposed at the junction of NH Rt. 115 and the Cherry Mountain road. The largest dike ...
Mobilization Of Metals By Fungi In Historic Cemeteries, 2015 Bates College
Mobilization Of Metals By Fungi In Historic Cemeteries, Eleanor D. Briggs
Interactions among fungi, soil, and metals are at the heart of nutrient cycling in terrestrial systems. Both major and trace elements are found in soils, but the degree to which they are biologically available is influenced by chemical weathering of soil minerals by fungi. In addition to contributing to weathering, mushrooms are known to bioaccumulate metals from soil, so edible mushrooms growing on soils contaminated with toxic metals can cause harm to those who eat them. This study focuses on metal content of mushrooms and soils from cemeteries that are suspected to be contaminated with arsenic as a result of ...
Insights Into The Evolution Of The Great Plains Grassland Ecosystem Over The Last 5 Million Years From Paleotemperature And Paleovegetation Records, Anne Fetrow
Honors Program Theses
Over the last 10 million years, the Great Plains transitioned to the modern C4 grass dominated ecosystem. Well-preserved late Miocene to Holocene fossils and paleosols make the Meade Basin in southwest Kansas, USA a unique place to determine how paleoenvironmental conditions changed during C4 grassland evolution. δ18O values of paleosol carbonates (δ18Ocarb) in the Meade Basin decreased from the Miocene to Holocene while δ13C values increased; these trends were interpreted as an increase in temperature and/or in aridity coincident with an increase of C4 grass biomass on the landscape ...
Possible Precursor Events To Earthquakes And The Resulting Effects On Organic Material In The Surrounding Water Bodies, Kiyoko Nakatsui
Student Research Day Abstracts and Posters
Being located on the “Ring of Fire” Japan experiences many seismic events. Adding to this, it is located at the convergence of four fault lines where seismic activity will be even more frequent and severe. Although small tremors occurring in an area are indicators of an earthquake to come it only gives minutes of warning. Scientists are now trying to see if latent heat and gas release from fault lines can indicate an earthquake to come with hours or even days of warning. MODIS aqua and terra data will be analyzed in order to see if such precursors can be ...
Geothermobarometry And Petrographic Interpretations Of Christensen Ranch Meta- Banded Iron Formation From The Ruby Range, Montana, 2015 Western Kentucky University
Geothermobarometry And Petrographic Interpretations Of Christensen Ranch Meta- Banded Iron Formation From The Ruby Range, Montana, Jacob Hughes
Honors College Capstone Experience/Thesis Projects
The Ruby Range in southwestern Montana was tectonically uplifted during the mountain-building event of the Big Sky orogeny. Contained within the Christensen Ranch Formation, made up of sedimentary units metamorphosed during the Big Sky orogeny, are a small number of metamorphosed banded iron formations (BIFs). It is the presence and composition of these BIFs which is the focus of this research, principally their depositional origin, relationship to surrounding sedimentary packages, elemental and mineral compositions, and lastly, peak metamorphic conditions. Samples were collected, cut into thin sections, and powdered for textural and compositional analyses employing polarized light microscopy, Raman microscopy, scanning ...

A Geochemical Study Of A Marsh Environment, 2015 Gulf Coast Research Laboratory
A Geochemical Study Of A Marsh Environment, Thomas F. Lytle, Julia Sever Lytle, Patrick L. Parker
Gulf and Caribbean Research
The goal of this study was twofold: 1) chemically to characterize a specific salt marsh, the sediments and associated biota and 2) to establish clear relationships between the chemical substances residing in the sediments and similar or identical substances occurring in the biological specimens. In this particular study it was felt that the hydrocarbons would yield the most significant organic geochemical information. These compounds are ubiquitous but minor components of all organisms. Though their function is not entirely understood, it is known that they are concentrated in the waxy coatings of plants and most likely aid in the protective mechanisms ...

A Study On Photodegradation And The Fate Of Pyrogenic Carbon, 2015 University of Southern Mississippi
A Study On Photodegradation And The Fate Of Pyrogenic Carbon, John T. Howell
Accounting for all possible sources of atmospheric CO2 is a pressing issue today due to the increasing effects of climate change. Estimates suggested that on the order of 1.3 million tons of dissolved pyrogenic carbon (pyDOC) could be entering the northern Gulf of Mexico annually. Assessing the fate of pyDOC in aquatic systems is crucial to understanding ecosystem impacts and potential feedback to climate change. Current research indicates that despite a generally lower susceptibility to biodegradation than their unpyrolyzed equivalents, pyrogenic carbon is not environmentally inert. While the role of microorganisms on the fate and transformation ...
Aerosol Size Distribution Measurements During The 2014 Nasa Sarp Campaign In The Central Valley And Sierra Nevada Mountains In California, Victoria A. Hampton
Honors College Capstone Experience/Thesis Projects
Aerosols are directly and indirectly related to global climate by scattering radiation and also by seeding cloud formation. As a part of the 2014 NASA Student Airborne Research Program (SARP), research flights were conducted over the Central California region to better understand air quality in large urban California cities and also in the Central Valley. Using a Droplet Measurement Technologies Ultra High Sensitivity Aerosol Spectrometer (DMT-UHSAS), aerosol size distributions were measured across geographic regions of interest. Previous research has suggested that aerosols originating in the Central Valley may travel eastward to the Sierra Nevada and, once lifted orographically, could suppress ...

Investigating Sedimentary Rocks To Understand Past Wet Climate Of Mars, 2015 University of New Orleans
Investigating Sedimentary Rocks To Understand Past Wet Climate Of Mars, Emily Harper
Senior Honors Theses
The “deltaic” geomorphology in the Eberswalde Crater is often considered a “smoking gun” for the warm-and-wet ancient climate of Mars. The Crater displays sedimentary features, which many argue, can only be found in a river-delta system (Bhattacharya et al., 2005). However, with the advent of high-resolution images, the Eberswalde Crater delta’s geomorphology has been revealed to be more complicated than could be seen previously. These high-resolution data suggest that the development of the Eberswalde delta is likely more episodic (Schieber 2007). While better resolution data has placed doubt on the wet Mars hypothesis at the Eberswalde Crater, the opposite ...
Hydrologic Mediation Of The Spatial And Temporal Variability Of The Soil Carbon Dioxide Stable Isotopic Composition Of A Subalpine Watershed, 2015 University of Nebraska-Lincoln
Hydrologic Mediation Of The Spatial And Temporal Variability Of The Soil Carbon Dioxide Stable Isotopic Composition Of A Subalpine Watershed, Theresa Marie Lorenzo
Dissertations & Theses in Natural Resources
The stable carbon isotopic composition of CO2 (δ13C-CO2) has been studied as an indicator of changes in ecosystem CO2 exchange. Soil moisture is an important factor in ecosystem CO2 exchange through its influence on physiological and soil physical processes. However, the majority of previous research analyzing the influence of soil moisture on soil and soil-respired δ13C-CO2 has been conducted with limited consideration of topographical variation, which controls the distribution of soil moisture across a landscape. This study characterized the stable isotopic composition (δ13C) and concentrations of soil CO2 ...
Seismic Imaging To Constrain Groundwater Models For A Better Understanding And Management Of Water Quality In Coastal Benin, West Africa: A Saltwater Intrusion Problem, Kyle Michael Lindsay
Boise State University Theses and Dissertations
The coastal city of Cotonou in Bénin, West Africa, is a large population center that is facing a serious threat to the sustainability of its fresh water supply. Cotonou relies on groundwater derived from the Godomey aquifer for its domestic water supply. The aquifer is undergoing saltwater intrusion due to an increase in pumping to accommodate a growth in population. Hence, there is substantial interest in better characterizing the groundwater system for the purpose of determining appropriate management strategies to ensure sustainability of this freshwater resource.
I collected seismic reflection data along 15 transects to characterize the geometry of the ...
