Assessment of Extraterrestrial Tracers Ir, Pt and ³He in Polar Ice Cores

Creator:: Mehmel, Nicholas C.
Abstract:: This thesis focuses on the investigation of extraterrestrial tracers Ir, Pt and 3He in polar ice cores. These tracers may be used to identify characteristics of interplanetary dust particles, and to quantify the flux of extraterrestrial material during impact events, certain volcanic eruptions, and stable background periods. In the first...

William Keith Brooks (1848-1908) : a case study in morphology and the development of American biology

Creator:: Benson, Keith Rodney
Abstract:: The major historical studies that have examined American biology have emphasized the development of experimental biology at the end of the nineteenth century. In this characterization, the descriptive branch of biology has often been treated as less than important and, in several cases, as a hindrance in the application of...

CommunityBridge: A Website for First-Generation and Underrepresented Student Success

Creator:: Marlen, Adrianna
Abstract:: Institutions of higher education are working to be more inclusive of underrepresented groups, including first-generation and low-income college students. Broadly, data show a significant population of diverse students are now entering higher education, but completion rates are comparatively lower than entry rates. To combat this, we need to evaluate ways...

Latinx Migrant and Seasonal Farmworker Students & the College Assistance Migrant Program: Stories of Strength, Persistence, and Success

Creator:: Hernandez Silva, Lesley
Abstract:: According to the U.S. Census Bureau (2017), Latinx people are the fastest growing ethnic group in the nation but are least likely to enroll in institutions of higher education and fewer eventually earn a degree even if enrolled. Enrollment rates for Latinx students with migrant and seasonal farmworker (MSFW) background...

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...

Hydraulic functions of soils from physical experiments and their applications

Creator:: Su, Charles
Abstract:: Based upon the Pearson Type VIII distribution function, a general retention function which relates the saturation to the capillary pressure in disturbed soils has been discovered. This simple and yet complete function has been shown to describe precisely the imbibition as well as the drainage branch of the retention curve....

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...
