Assessing Soil Redox Conditions Using Iris Tubes In A Central Georgia Wetland, Cameron Skinner 2018 Georgia College and State University

Assessing Soil Redox Conditions Using Iris Tubes In A Central Georgia Wetland, Cameron Skinner

Georgia Undergraduate Research Conference (GURC)

The process of documenting soil redox potential has become increasingly important to environmental professionals for use in wetland delineation studies. Wetlands are characterized by hydric soils, which are formed in saturated conditions, and are typically home to an anaerobic, reducing redox environment. Most established wetland delineation studies document soil redox conditions through Eh measurements via platinum electrodes and/or alpha-alpha-dipyridyl dye. However, these methods are costly, time-intensive, and complex. An alternative method of assessing reduction potential in situ is through the use of Iron Reduction in Soils (IRIS) tubes, which are fabricated from PVC pipes that have been sanded and ...


Phosphate Desorption Across Particle Size After Sustainable Agriculture Practices, Zachary Davis 2018 Georgia College and State University

Phosphate Desorption Across Particle Size After Sustainable Agriculture Practices, Zachary Davis

Georgia Undergraduate Research Conference (GURC)

Within a watershed, increased phosphate (PO43-) concentrations can result in accelerated eutrophication, a process through which excess amount of nutrients, such as nitrogen (N) and phosphorus (P), lead to accelerated algae growth and eventual decay, depleting dissolved oxygen. The study site, Babe and Sage Farm in Gordon, Georgia, is a small sustainable farm that follows USDA regulations for Organic production. The farmers were seeking field research to determine the efficiency and sustainability of their practices related to fertilizer (nutrient) applications. This study investigates horizontal and vertical phosphate movement though soils to assess the impacts of sustainable agriculture practices ...

Designing Climate Policy: Lessons From The Renewable Fuel Standard And The Blend Wall, Gabriel E. Lade, C.-Y. Cynthia Lin Lawell, Aaron Smith 2018 Iowa State University

Designing Climate Policy: Lessons From The Renewable Fuel Standard And The Blend Wall, Gabriel E. Lade, C.-Y. Cynthia Lin Lawell, Aaron Smith

Economics Working Papers

Many policies mandate renewable energy production to combat global climate change. These policies often differ significantly from first-best policy prescriptions. Among the largest renewable energy mandates enacted to date is the Renewable Fuel Standard (RFS), which mandates biofuel consumption far beyond what is feasible with current technology and infrastructure. In this article, we critically review the methods used by the Environmental Protection Agency to project nearand long-term compliance costs under the RFS, and draw lessons from the RFS experience to date that would improve the program’s efficiency. The lessons are meant to inform both future RFS rulemaking and the ...


Groundwater Recharge Response To Reduced Irrigation Pumping In Western Nebraska, Justin Philip Gibson 2018 University of Nebraska-Lincoln

Groundwater Recharge Response To Reduced Irrigation Pumping In Western Nebraska, Justin Philip Gibson

Dissertations & Theses in Natural Resources

Given current and continued investment in irrigation scheduling technologies, a need exists to better estimate the longevity and magnitude of water savings at watershed level to avoid the paradox of irrigation efficiency. This paradox occurs within a watershed as not all irrigation inefficiencies lead to the system losing water. For example, irrigation pumping rates in excess of crop water demand may lead to enhanced groundwater recharge or surface runoff that migrates to a stream. Thus, increases in efficiency may not lead to similar magnitudes of water savings. I hypothesize that water savings longevities are short given previous work demonstrating rapid ...


Examining Patterns In Nest Predation Using Artificial Nests, Victoria L. Simonsen 2018 University of Nebraska-Lincoln

Examining Patterns In Nest Predation Using Artificial Nests, Victoria L. Simonsen

Dissertations & Theses in Natural Resources

The use of artificial nests to study the predation of avian nests has faced disregard by ecologists due to inconsistencies found between the survival rates of real and artificial nests across studies and reviews. The negative perception of artificial nests providing an inconsistent assessment of survival has thus fostered the perception that artificial nests are a secondary option to be used to overcome logistical hurdles associated with achieving sufficient sample sizes in systems where study species are rare or elusive, or as merely a preliminary method to study predation across gradients. We argue that the greatest mistake ecologists have made ...

Longitudinal Study Of The Attitudes And Behaviors Of Environmental Education Program Participants., Kasie R. Dugas

LSU Master's Theses

The goal of this longitudinal study was to measure the attitudes and behaviors of participants of the Marsh Maneuvers program over the course of the last 25 years. The goal of the Marsh Maneuvers program is to educate students into becoming environmentally literate adults. Environmental literacy is considered herein to be people possessing knowledge about and positive attitudes and behaviors towards the environment. Although students learn basic science and environmental knowledge in the classroom, true environmental literacy is believed to require more hands-on understanding of the material. To evaluate the effectiveness of the program, the following three objectives were completed ...


Eddy Flux Measurements Of Sulfur Dioxide Deposition To The Sea Surface, Jack G. Porter, Warren J. De Bruyn, Eric S. Saltzman 2018 University of California, Irvine

Eddy Flux Measurements Of Sulfur Dioxide Deposition To The Sea Surface, Jack G. Porter, Warren J. De Bruyn, Eric S. Saltzman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Deposition to the sea surface is a major atmospheric loss pathway for many important trace gases, such as sulfur dioxide (SO2). The air–sea transfer of SO2 is controlled entirely on the atmospheric side of the air–sea interface due to high effective solubility and other physical– chemical properties. There have been few direct field measurements of such fluxes due to the challenges associated with making fast-response measurements of highly soluble trace gases at very low ambient levels. In this study, we report direct eddy covariance air–sea flux measurements of SO2, sensible heat, water vapor, and momentum. The measurements ...


Selective Glucose Isomerization To Fructose Via Nitrogen-Doped Solid Base Catalyst Derived From Spent Coffee Grounds, Season S. Chen, Iris K.M. Yu, Dong-Wan Cho, Hocheol Song, Daniel C.W. Tsang, Jean-Philippe Tessonnier, Yong Sik Ok, Chi Sun Poon 2018 Iowa State University

Selective Glucose Isomerization To Fructose Via Nitrogen-Doped Solid Base Catalyst Derived From Spent Coffee Grounds, Season S. Chen, Iris K.M. Yu, Dong-Wan Cho, Hocheol Song, Daniel C.W. Tsang, Jean-Philippe Tessonnier, Yong Sik Ok, Chi Sun Poon

Chemical and Biological Engineering Publications

In this work, glucose isomerization to fructose was conducted via a solid base biochar catalyst derived from spent coffee grounds and melamine. The X-ray photoelectron spectroscopy (XPS) spectra identified the majority of pyridinic nitrogen on the biochar surface, which imparted the strong base character of the catalyst. Activity of the catalyst was evidenced by fast conversion of glucose (12%) and high selectivity to fructose (84%) in 20 min at a moderate temperature (120 °C) compared to recently reported immobilized tertiary amines at comparable N concentrations (10-15 mol% relative to glucose). By increasing the reaction temperature to 160 °C, fructose yield ...
