Demographics And Risk Of Isolation Due To Sea Level Rise In The United States, Kelsea Best, Qian He, Allison C. Reilly, Deb A. Niemeier, Mitchell Anderson, Tom Logan

School of Earth & Environment Departmental Research

Within coastal communities, sea level rise (SLR) will result in widespread intermittent flooding and long-term inundation. Inundation effects will be evident, but isolation that arises from the loss of accessibility to critical services due to inundation of transportation networks may be less obvious. We examine who is most at risk of isolation due to SLR, which can inform community adaptation plans and help ensure that existing social vulnerabilities are not exacerbated. Combining socio-demographic data with an isolation metric, we identify social and economic disparities in risk of isolation under different SLR scenarios (1-10 ft) for the coastal U.S. We show …

• There was a larger than average area with 51–60% groundcover, and groundcover in these areas is expected to reduce over summer to below 50%.
• About 2% of the grainbelt (293,000 ha) had less than 50% groundcover, which is inadequate to prevent wind erosion. Mullewa to Morawa Ag Soil Zone had the highest risk of wind erosion and 8% of this farmland had inadequate groundcover. …

A Climatology Of Mesoscale Airmasses With High Theta-E, Charles J. Kropiewnicki

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

A Mesoscale Airmass with High Theta-E (MAHTE) is a narrow region of larger theta-e located on the cool side of an airmass boundary. MAHTEs typically possesses higher CAPE than the warm side of the boundary, creating a more favorable environment for severe convection. MAHTEs can also be characterized by larger low-level shear and lower LCLs and may also have a propensity for supporting tornadogenesis. The majority of MAHTE research to date has been comprised of case studies, and the prevalence of MAHTEs is not well understood. This project fills that knowledge gap by creating a climatology of MAHTE occurrence. This …

Here we develop two new social indices: The ADA PARC Absolute Economic Opportunity Index and the ADA PARC Relative Economic Opportunity Index. These indices allow us novel examinations of economic equity between people with and without disabilities within a U.S. State and between people with disabilities in different states using aggregations of multiple component economic indicators. These represent the first efforts to offer U.S. indices of this focus, an important development given the distinct economic needs of people with disabilities and the value in accounting for distinct national policies. The indices rely on U.S. Census and other data on economic …

Editorial: Solutions To Water Crises (Related To Actual Interventions), Jenia Mukherjee, Saket Pande, Melissa Haeffner, Sara Marks, Pieter Van Oel, Matthew Sanderson, Adriana Allen

Environmental Science and Management Faculty Publications and Presentations

Water science has become “pluralistic” (Evers et al., 2017) to collectively (yet differently) understand complex water systems with promising combinations of compatible and complementary disciplines. The contemporary context of water science discusses the more severe water-society challenges of the Anthropocene. Yet, the conversation is not definitive; indeed, there are unending debates between quantitative and qualitative research approaches including methodological choices and accuracies along questions of scales, themes, and politics of funding. Transdisciplinary applications and cross-sectoral engagements offer solution-oriented water just trajectories – scientists, practitioners, and user groups designing and deploying “solutions” related to actual interventions in addressing water …

Examining The Externalities Of Highway Capacity Expansions In California: An Analysis Of Land Use And Land Cover (Lulc) Using Remote Sensing Technology, Serena E. Alexander, Bo Yang, Owen Hussey, Derek Hicks

Mineta Transportation Institute

There are over 590,000 bridges dispersed across the roadway network that stretches across the United States alone. Each bridge with a length of 20 feet or greater must be inspected at least once every 24 months, according to the Federal Highway Act (FHWA) of 1968. This research developed an artificial intelligence (AI)-based framework for bridge and road inspection using drones with multiple sensors collecting capabilities. It is not sufficient to conduct inspections of bridges and roads using cameras alone, so the research team utilized an infrared (IR) camera along with a high-resolution optical camera. In many instances, the IR camera …

Wics Conference 2023: Moving Beyond The Ordinary, Daren Redfearn, Daran Rudnick

Water and Integrated Cropping Systems Conferences

The theme of this year’s WICS Conference is Moving Beyond the Ordinary with the goal of addressing Team Science. Our vision is to provide opportunities and connection points among IANR faculty to leverage their individual knowledge, skills, abilities, and passions. A tendency for land grant institutions is often to deliver information biased from a single, primary discipline and perspective. This is known as comfort zone mega bias and has been defined as “the tendency to drag a problem into our comfort zone and solve the problem that we know how to solve, rather than solving the problem that needs to …

A Song In A Cold Place: The Role Of Emotions In Motivating Youth Activism And Advancing Justice At The Cop, Julia Coombs Fine, Summer Gray, Corrie Grosse, Brigid Mark

Environmental Studies Faculty Publications

The emotions of youth climate justice activists are often demeaned or misrepresented both by popular media and by COP organisers. The COP itself, as a cold, bureaucratic, and repressive space that tokenises frontline voices to create an optics of care, is a source of frustration and disappointment for many youth activists. Despite this misrepresentation and repression, youth activists use their emotions to strengthen their movements and actions at the COP. Drawing on collaborative event ethnography spanning a decade, this paper analyses how Global South youth climate justice activists strategically navigate and channel emotion through acts of emotional solidarity, emotional concealment, …

Stable Isotope Analysis On Yellowfin And Blackfin Tuna Eye Lenses Reveals Life History Patterns In The Gulf Of Mexico, Kylee M. Rullo

USF Tampa Graduate Theses and Dissertations

Spatial geography, ontogenetic movement, and trophic patterns of mobile species are key elements of effective marine resource management. A number of methods are currently available for tracking movements of pelagic migratory species, including the use of conventional and electronic tags. However, tagging campaigns can take years to provide useful data, can be expensive, and only capture a portion of a fish’s lifetime. For this project, I used stable-isotopic ratios of nitrogen (δ15N) and carbon (δ13C) in metabolically inert, chronologically-layered fish-eye lenses to explore lifetime movement and trophic patterns of yellowfin tuna (Thunnus albacares) and blackfin tuna (Thunnus atlanticus) in the …

Faculty Publications

In their commentary, Xiao et al. cautioned that the conclusions on the critical role of microbial carbon use efficiency (CUE) in global soil organic carbon (SOC) storage in a paper by Tao et al. (2023) might be too simplistic. They claimed that Tao et al.’s study lacked mechanistic consideration of SOC formation and excluded important datasets. Xiao et al. brought up important points, which can be largely reconciled with our findings by understanding the differences in expressing processes in empirical studies and in models.

How Megatooth Sharks Ruled And Fell: Evidence From Stable Isotopes In Bioapatite, Michael Griffiths

Sustainability Seminar Series

The evolution and extinction of megatooth sharks, especially Otodus megalodon, have long puzzled scientists. A growing body of evidence suggests that the evolution of gigantism in these sharks, perhaps driven by their ability to thermoregulate, played a crucial role in their ecological success and response to environmental changes. Yet, until recently, the question of whether O. megalodon was ectothermic or endothermic was based solely on nonempirical inferences. In this presentation, Dr. Griffiths will present new research that involves the geochemical analysis of both modern and fossil shark teeth to shed light on O. megalodon's thermoregulation, revealing it maintained a warmer …

Cognitive Digital Modelling For Hyperspectral Image Classification Using Transfer Learning Model, Mohammad Shabaz, Mukesh Soni

Turkish Journal of Electrical Engineering and Computer Sciences

Deep convolutional neural networks can fully use the intrinsic relationship between features and improve the separability of hyperspectral images, which has received extensive in recent years. However, the need for a large number of labelled samples to train deep network models limits the application of such methods. The idea of transfer learning is introduced into remote sensing image classification to reduce the need for the number of labelled samples. In particular, the situation in which each class in the target picture only has one labelled sample is investigated. In the target domain, the number of training samples is enlarged by …
