Distribution of encrusting foraminifera at Mayaguana, Bahamas: Determining assemblage composition and relationship of test size and density to food availability
(2018-08-01)
Benthic foraminifera that are cemented by calcium carbonate or are otherwise firmly fixed to hard surfaces are known as encrusting or attached foraminifera. Relatively few actualistic studies focus on the use of encrusting ...
Drought Management Plans in Major Cities of the Southeastern U.S. v. Western U.S.
(2019-04-23)
The severe drought conditions impacting California and the Western United States over the last several years have led to greater awareness of the consequences of water scarcity and the need for effective drought policy. ...
Drought Management Plans of States in the Southeastern United States: A Comprehensive Evaluation
(2023-05-16)
While the Southeast is often considered to be a region of abundant rainfall and humidity, severe droughts over the last two decades have raised awareness of the importance of proper management strategies at the state level. ...
Effect of landuse and landcover change and climate change on the hydrological response and water quality of Big Creek Lake Watershed South Alabama USA
(2021-07-12)
Land use and climate are the two key factors affecting the hydrological processes of a watershed. This research aimed to evaluate the impact of changing land use and land cover (LULC) and climate change on hydrological ...
The Effectiveness of the Augmented Reality Sandbox for Improving Spatial Thinking in Undergraduates
(2019-04-23)
Spatial reasoning ability is a necessary skill for success in any of the science, technology, engineering, and mathematics (STEM) domains. Research suggests that spatial thinking ability and exposure to opportunities aimed ...
Ejecta Stratigraphy Modeling of the NASA/VIPER Exploration Zone at Mons Mouton Near the Lunar South Pole
(2023-04-24)
Permanently shadowed regions (PSRs) within some lunar polar craters host water ice and other volatiles delivered by sources such as asteroids, comets, interior degassing, and solar wind sputtering because of their frigid ...
Evaluating the Impact of Onsite Wastewater Treatment Systems on Watershed Contamination, Choccolocco Creek Watershed, Alabama
(2022-06-29)
There is increasing evidence that onsite wastewater treatment systems (OWTSs) can be a significant, and possibly underestimated, source of water contamination. OWTSs effectively treat wastewater when located in suitable ...
Evaluating The Three Dimensions of Usability for an Online Climate Modeling Tool: A Coproduced Eye Tracking Study
(2023-08-01)
Science tools provide educators with a method to teach their students complex issues like climate change, however, there is still much work to be done to ensure that science tools are efficient and usable for teachers and ...
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. ...
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 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 ...
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 ...
