Assessing The Effect Of A Human-Made Reservoir On The Mussel Community In Caney Creek, Trakker Estes
Assessing The Effect Of A Human-Made Reservoir On The Mussel Community In Caney Creek, Trakker Estes
ATU Scholars Symposium
Freshwater mussels are one of the most threatened taxonomic groups globally, with less than 32% of North American taxa considered secure. In Arkansas, over half of the state’s 85 species are endangered, threatened, or of special concern. Small impoundments may contribute to these declines through reduced hydrological connectivity and the resulting decline of fish community movement. This study examines the effects of Tri-County Lake, a small impoundment of Caney Creek in southern Arkansas, on mussel abundance and diversity. In total, eight sites were surveyed upstream, within, and downstream of the impoundment across various habitat types. A timed-search approach utilizing scuba …

Generating Channel Morphology Data Through Arcgis Pro, Ethan Manigbas
Symposium of Student Scholars
River cross-sections are often extracted using field surveys at measured intervals. This field-oriented approach allows for a tangible relationship between the data and its collector but at the expense of finance, time, labor, and potentially the environment. With the advancement of geospatial tools, such data can be found online, extracted, and even analyzed with contemporary Geographic Information Systems (GIS) in a completely virtual setting, transcending the need for fieldwork in select project topics. We tested this approach with the help of ArcGIS Pro software on the Vishnu Springs headwater stream located in the Western Illinois region of the Upper Mississippi …
Mapping The Impact Of A Trailway System On The Amount Of Trash Present Within Two Watersheds Of Lynchburg City, Virginia, Lillian Smith
Mapping The Impact Of A Trailway System On The Amount Of Trash Present Within Two Watersheds Of Lynchburg City, Virginia, Lillian Smith
Student Scholar Showcase
Transportation of trash debris within water systems is a prominent occurrence which has been linked to natural and artificial processes such as wind, rain, and littering. Recreational areas, such as activities along greenway trails, have been determined to be a source of debris found in waterways. This study examines whether the presence of an established recreational trail system limits trash accumulation in the entirety of a watershed. Trash data collected at Blackwater Creek, which contains an established trail system, was compared to trash data collected at Fishing Creek, containing a non-established trail system, to answer this hypothesis. A distance of …

Downscaling Methodology For Satellite Land Surface Temperatures Over Urban Environments, Naved Khan, Ruben Vecino
Publications and Research
The objective of this study is to develop high spatial and temporal resolution Land Surface Temperature (LST) data using a combination of Landsat 8, infrared satellite sensors such as the Moderate Resolution Imaging Spectroradiometer (MODIS), and the Geostationary Operational Environmental Satellite-R Series (GOES-16). The Landsat 8 Thermal Infrared Sensor (TIRS) provides higher spatial resolution (30 m) estimates of skin temperature every 16 days. MODIS makes daytime and nighttime observations of the Earth’s thermal emission at a coarser spatial resolution (1000 m), while GOES-16, which has lower spatial resolution (2 km), measures the skin temperature at a much higher temporal resolution …
What Is The Most Threatening Disaster To The Continental United States?, Aaron Spomer, Elijah Kaufman, Julisa Prieto-Garcia, Brooke Aschwanden
What Is The Most Threatening Disaster To The Continental United States?, Aaron Spomer, Elijah Kaufman, Julisa Prieto-Garcia, Brooke Aschwanden
UNO Student Research and Creative Activity Fair
Our goal for our project is to fully understand which natural disaster is the most destructive to the United States. We have chosen to compare hurricanes, floods, tornadoes, wildfires, earthquakes, and nor’easters. We have researched the cost of the total damage and repair, how the warning systems have improved over time, the death tolls from each, and also the frequency at which each one occurs. Each group member will research a different disaster impact, and the data will create a comprehensive view of the level of devastation each disaster has. We collected data all the way from the early 1900s …
Recovering From Industrial Overshoot: Thermal Removal Of Atmospheric Co2, Ted Von Hippel, Sandra Boetcher, Matthew Traum, Farshid Azadian Ph.D., William Mackunis
Recovering From Industrial Overshoot: Thermal Removal Of Atmospheric Co2, Ted Von Hippel, Sandra Boetcher, Matthew Traum, Farshid Azadian Ph.D., William Mackunis
Sustainability Conference
Humanity will soon overshoot a safe level of atmospheric CO2, if it hasn't done so already. Countries, industries, and the global economy need to dramatically and quickly alter their behavior and technology to avoid this dangerous overshoot, yet this appears unlikely. Direct Air Capture of CO2 represents an insurance policy for society - a way of removing excess atmospheric CO2. I will present an approach to this problem based on thermal physics that cools cubic kilometers of air to extract CO2 as it sublimates. I propose a combination of an efficient heat exchanger, radiative cooling, and refrigeration, all at industrial …

A Toolkit For Managing The Ee (Environmental Education) And Esd (Education For Sustainable Development) Continuum, Attiyya Atkins, John J. Pipoly Iii
Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures
Environmental Education (EE) and Education for Sustainable Development (ESD) represent extremes of a global continuum. EE stresses awareness of process about, from and for the environment (Vrasidas 2007). ESD is defined as education empowering communities to acquire best management practices engendering human, social, economic and natural sustainability (UNESCO 2012) and developing their resilience despite environmental changes (Fastenrath et al. 2019). ESD is a critical component of the UN's Sustainable Development Goals (UN 2012), which grew from the Millennium Development Goals (UN 2000). Each park agency should develop research-based educational programs that address both EE and ESD. The ESD must promote …

Analysis Of Land Surface Temperature Over Urban Landcover Types Using Satellite Remote Sensing And Ground-Based Applications, Makini Valentine, Justine Ginchereau
Publications and Research
Urban areas have discrete differences in their land surface temperatures (LST) compared to rural areas. These regions are covered with impermeable materials with less vegetation and moisture. Consequently, this phenomenon causes major thermal intensities of different land surfaces, negatively impact people and environment. The objective of this project is to examine and to compare land surface temperature obtained from in-situ data and satellite-based observations in order to understand the diurnal variation and heat transfer at each surface type. The study utilizes series of hand held thermal infrared cameras and one Unmanned Aerial Vehicle (UAV) infrared camera to find land surface …

Unusual Isotopic Effects Produced In Precipitation As A Byproduct Of Unusual Atmospheric Processes, Shelby Hurst
Research and Creative Activities Poster Day
Precipitation is the ultimate source of all surface and groundwater recharge. Stable oxygen and hydrogen isotope investigation of precipitation has a long history. The factors controlling these stable isotopes are well known and include mean annual temperature, amount of precipitation, altitude and air mass trajectory (Dansgaard, 1964; Yurtsever and Gat, 1981).
Improving Our Understanding Of Ocean Circulation: A Modeling Study, Nicole M. Flecchia
Improving Our Understanding Of Ocean Circulation: A Modeling Study, Nicole M. Flecchia
Senior Honors Projects
The Gulf Stream is not a rigidly contained ocean current; it curves and meanders in a manner that causes portions of it to go unstable, breaking off to form warm core rings. These rings travel west – due to the earth’s rotation - through the Slope Sea and onto the southern New England shelfbreak, affecting various physical parameters of our coastal waters as well as the biogeochemical and ecological properties (i.e. the ‘health’) of the those waters. Where a warm core ring lands along the east coast and the time of year it appears varies with each ring, causing each …
Low-Cost Hab Platform To Measure Particulate Matter In The Troposphere, Mark J. Potosnak, Bernhard Beck-Winchatz, Paul Ritter
Low-Cost Hab Platform To Measure Particulate Matter In The Troposphere, Mark J. Potosnak, Bernhard Beck-Winchatz, Paul Ritter
2017 Academic High Altitude Conference
High-altitude balloons (HABs) are an engaging platform for formal and informal STEM education. However, the logistics of launching, chasing and recovering a payload on a 1200 g or 1500 g balloon can be daunting for many novice school groups and citizen scientists, and the cost can be prohibitive. In addition, there are many interesting scientific applications that do not require reaching the stratosphere. In this poster presentation we discuss a novel approach based on small (30 g) balloons that are cheap and easy to handle, and low-cost tracking devices (SPOT and 900 MHz spread spectrum) that do not require a …

Challenges Associated With Space Weather Analysis And Prediction, John Lanicci
Space Traffic Management Conference
The term “space weather” is typically used to describe environmental conditions in the region extending from the sun’s surface, through the interplanetary medium, to the earth’s magnetic field and upper atmosphere, with a focus on those conditions that can affect the earth, its technological systems, and population. Space weather conditions are monitored continuously by a number of agencies around the world. These agencies use both satellite- and ground-based measurements to build analyses and employ predictive models that form the basis for impacts-based products dealing with myriad users in satellite operations, the utility industry, aviation, and satellite-based communications, to name a …

Identification Of Ttl Boundaries Using The Ozone-Water Vapor Relationship, Laura Pan
Identification Of Ttl Boundaries Using The Ozone-Water Vapor Relationship, Laura Pan
U.S. - Japan Bilateral Workshop on the Tropical Tropopause Layer: State of the Current Science and Future Observational Needs
Two sets of TTL boundary definitions have been proposed in the literature. One uses the static stability structure (Gettelman and Foster, 2002) and the other uses the radiative forcing mass flux criterion (Fu et al., 2007; Fueglistaler et al., 2009). In this work, we present a method to characterize the TTL boundaries using ozone–water vapor relationship. The result shows that the tracer behavior supports the level of the minimum stability to be the lower boundary of the transition layer and the cold point to be a good proxy of the upper boundary. Using this method, we characterize and compare the …
Ozone Variations Over The Northern Subtropical Region Revealed By Ozonesonde Observations In Hanoi, Shin-Ya Ogino
Ozone Variations Over The Northern Subtropical Region Revealed By Ozonesonde Observations In Hanoi, Shin-Ya Ogino
U.S. - Japan Bilateral Workshop on the Tropical Tropopause Layer: State of the Current Science and Future Observational Needs
Seasonal and subseasonal variations in the ozone mixing ratio (OMR) are investigated by using continuous seven-year ozonesonde data from Hanoi (21 0 N, 106 0 E), Vietnam. The mean seasonal variations for the seven years show large amplitude at the upper troposphere and lower stratosphere (UTLS) region (10–18 km) and at the lower troposphere (around 3 km) with standard deviations relative to the mean value of about 30% for both regions. In the UTLS region, the seasonal variation in the OMR shows a minimum in winter and a maximum in spring to summer. The variation seems to be caused by …

U.S. - Japan Bilateral Workshop on the Tropical Tropopause Layer: State of the Current Science and Future Observational Needs
Asian summer monsoon (ASM) anticyclone circulation is recognized to be a significant transport pathway for water vapor and pollutants to enter the stratosphere. Observational evidence, however, is largely based on satellite retrievals. We report the first coincident in situ measurements of water vapor and ozone within the ASM anticyclone. The combined water vapor and ozone sondes were launched from Kunming in August 2009 and Lhasa in August 2010. We present the key characteristics of these measurements, and provide a comparison to similar measurements from Alajuela, Costa Rica, an equatorial location, during the Tropical Composition, Cloud and Climate Coupling (TC4) campaign …

U.S. - Japan Bilateral Workshop on the Tropical Tropopause Layer: State of the Current Science and Future Observational Needs
Cirrus clouds in the TTL play an important role on the radiation budget and thus the understanding of their optical properties together with the microphysical processes associated with their formation is quite important. In spite of the progress in theoretical research on the TTL cirrus (e.g., Koop et al., 2000; Peter et al., 2006), observational research is not enough because of the difficulty due to its height and coldness. On the other hand, research of cirrus clouds at 10 km height has been carried out since 1990s using aircraft and hydrometer sondes such as HYVIS (Murakami and Orikasa, 1997) and …

Impact Of Abrupt Stratospheric Dynamical Change On Tropical Tropopause Layer, Nawo Eguchi, Kunihiko Kodera, Tomoe Nasuno
U.S. - Japan Bilateral Workshop on the Tropical Tropopause Layer: State of the Current Science and Future Observational Needs
We have studied the impact of stratospheric circulation change on water vapor in the Tropical Tropopause Layer (TTL) during the stratospheric sudden warming (SSW) events (e.g., Eguchi and Kodera, 2010). Increased Brewer-Dobson circulation associated with SSW produces cooling in the tropical lower stratosphere (LS). The cooling generally produces more cirrus clouds and decreases of the water vapor mixing ratio (WV) in the TTL, except for some regions over Africa and South American continents where penetrating clouds are expected. This time, we found a new stratospheric phenomenon which produces abrupt warming in the tropical stratosphere converse to the SSW event. The …

Tandem optical particle counters (OPC) were launched by balloon, from Biak 1 0 S, 136 0 E in January 2011 and 2012. One of the tandem OPC directly observed size distribution of aerosols of 0.3 – 7 µm in diameter, and another one observed size distributions in heated conditions of 100 0 , 150 0 , and 200 0 C through thermodenuder, to observe volatility of TTL aerosols. Most of TTL aerosol smaller than 0.8 µm in diameter show high volatility, suggesting to be composed of sulfuric acid or sulfate. There also exist non-volatile particles larger than 0.8 µm in …
