An examination of the late Miocene C4 grass expansion through sedimentary charcoal morphometrics and morphotypes
(2026-04-23)
The C4 Fire Hypothesis posits that an increase in fire was the catalyst for the late Miocene C4 grass expansion by clearing forest canopies to create and maintain open landscapes preferred by C4 grasses, creating a positive ...
Expanding the Measurement, Use, and Support of Spatial Reasoning in STEM and the Geosciences
(2023-08-01)
Spatial thinking has been well-described and characterized for many STEM fields, and there have been numerous studies that emphasize the importance of incorporating spatial opportunities early and often throughout curricula. ...
Exploration of groundwater knowledge and private well programs across the United States
(2024-04-24)
Groundwater serves one third of the United States (US) population as their main source of drinking water. Groundwater accessed from private wells serves about 15% of the population. Private well water is not regulated by ...
Exploring and Measuring the Teaching and Development of Earth Systems Thinking Skills in Undergraduate Geoscience Courses
(2020-04-24)
The understanding of the development of Earth systems thinking (EST) is a major challenge in the field of geoscience education. Major questions exist relating to systems thinking teaching practices, student conceptions ...
Exploring Causal Factors that Impact Local Climate Variability to Enhance Community Preparedness and Mitigation Strategies for Coastal Small and Medium-Sized Cities (SMSC) and Counties
(2024-11-26)
This dissertation investigates the causal factors affecting local climate variability in coastal small and medium-sized cities (SMSC) and counties, aiming to enhance community preparedness and formulate effective mitigation ...
Exploring Geochemical Methods to Measure Arsenic-Dissolved Organic Matter Complexes and Coal Combustion Residuals in Surface Water
(2022-08-15)
Chapter 1, investigates the geochemical controls governing arsenic (As) mobility, precisely the formation of As-DOM complexes. Dissolved organic matter (DOM) reduces As mobility through equilibrium binding of As to the ...
Exploring the use of ground penetrating radar for determining floodplain function of restored streams in the Gulf Coastal Plain, Alabama
(2018-05-01)
Accurately characterizing subsurface structure and function of remediated floodplains is indispensable in understanding the success of stream restoration projects. Although many of these projects are designed to address ...
A field and geochemical investigation of tourmaline occurrences around the Hog Mountain gold deposit, AL
(2025-04-30)
Tourmaline can be a powerful mineral as its properties allow it to preserve information that can be used to uncover its geologic history. Abundant, previously undocumented occurrences of tourmaline have been discovered in ...
Field and laboratory investigations of groundwater arsenic sequestration in biogenic pyrite at an industrial site in Florida
(2020-05-07)
Pumping groundwater from arsenic-contaminated aquifers has exposed millions of people around the world to high and potentially deadly doses of the contaminant. Moreover, developing countries lack the resources and technology ...
Finding Fault in Dyer County, Tennessee: Exploring the Relationships of Earthquake-Induced Liquefaction Features to Subsurface Faults
(2018-12-17)
The New Madrid Seismic Zone (NMSZ) is located within the northern Mississippi Embayment, a northeast-striking graben that formed as a part of a failed rift system and later filled with sediments. Although this intracontinental ...
Forearc Basins Complexity and Evolution in Controlling Earthquake Rupture Segmentation of the Cascadia Subduction Zone
(2025-04-22)
The Cascadia subduction zone is a prominent seismic risk for North America. The primary objective is to comprehend the long-term behavior of the subduction zone by examining the structural and stratigraphic changes documented ...
