Pine Tree Dosimetry: Development of Geometric and Compositionally Specific Sectional Models for Organ Dose Assessment

Creator:: Condon, Caitlin A.
Abstract:: Ideally, dosimetric models for pine trees will accurately reflect the doses to its critical organs. However, existing models (e.g. that in ICRP 108) for the pine tree are over simplified or solely focused on estimating doses to one specific organ, and none of the existing models attempt dosimetry to the...

Biological Soil Crusts of the Great Basin : An Examination of their Distribution, Recovery from Disturbance and Restoration

Creator:: Condon, Lea A.
Abstract:: We are at risk of losing the sagebrush steppe in the floristic Great Basin to the invasion of Bromus tectorum L., cheatgrass. The floristic Great Basin includes the Central Basin and Range, the Northern Basin and Range, and the Snake River Plain. The Great Basin receives most of its precipitation...

A study of the stylistic ramifications of Father Charles Edward Coughlin's sermons from 1930 to 1934

Creator:: Acklin, Melissa Barrett
Abstract:: During the depression era, millions of Americans listened to the weekly radio addresses given by Father Charles Edward Coughlin. He devoted his career to speaking out against the evils of America and felt it his duty to warn Americans against the perpetrators of this evil. But after 1934, the tone...

Interpreting Climate of the Past from High-Resolution Ice Core Records of Methane

Creator:: Lee, James E.
Abstract:: Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...

Impact of Dansgaard-Oeschger and Heinrich Events on the Latitudinal Distribution of Methane Sources during Marine Isotope Stage 3

Creator:: Edwards, Jon S.
Abstract:: Understanding how the latitudinal distribution of methane sources changed between stadial and interstadial climate states during the last glacial period can provide important clues about how terrestrial hydroclimate and ecosystems evolved between these different states. The punctuation of the millennial-scale structure by Heinrich events is also of interest in this...

Understanding Signals of the South Pole Ice Core: Chronology, Climate, and Firn Processes

Creator:: Epifanio, Jenna A.
Abstract:: The South Pole ice core (SPC14), drilled in the field seasons of 2014/2015 and 2015/2016, is an intermediate length, 1,751-m ice core which preserves a 54,000-year record of past climate and atmospheric composition. The SPC14 ice core adds to the spatial grid of ice cores in Antarctica extending into the...

The late holocene atmospheric methane budget reconstructed from ice cores

Creator:: Mitchell, Logan E.
Abstract:: Ice cores are considered the gold standard for recording past climate and biogeochemical changes. However, gas records derived from ice core analysis have until now been largely limited to centennial and longer timescales because sufficient temporal resolution and analytical precision have been lacking, except during rare times when atmospheric concentrations...

10Be exposure ages of erratic boulders in southern Norway and implications for the history of the Fennoscandian Ice Sheet

Creator:: Goehring, Brent M.
Abstract:: This thesis focuses on the application of the cosmogenic nuclide Beryllium-10 (10Be) in an effort to better constrain the thickness history of the Fennoscandian Ice Sheet (FIS) at the Last Glacial Maximum (LGM) and into the Holocene, as well as begin to answer the long-standing question regarding the age and...

Stable Isotope Constraints on Carbon Dioxide and Nitrous Oxide Variations at the Onset of the Last Glacial Period: New Ice Cores from Taylor Glacier, Antarctica

Creator:: Menking, James A.
Abstract:: New ice cores retrieved from the Taylor Glacier (Antarctica) blue ice area contain ice and air spanning the Marine Isotope Stage (MIS) 5/4 transition, a period of global cooling and ice sheet expansion. Chronologies were determined for the ice and air bubbles in the new ice cores by visually matching...

Carbon cycle variability during the last millennium and last deglaciation

Creator:: Bauska, Thomas K.
Abstract:: The exchange of carbon on earth is one of the fundamental processes that sustains life and regulates climate. Since the onset of the Industrial Revolution, the burning of fossil fuels and anthropogenic land conversion have altered the carbon cycle, increasing carbon dioxide in the atmosphere to levels that are unprecedented...
