The Suppression Of Ocean Waves By Biogenic Slicks, Nathan J. M. Laxague, Christopher Zappa, Shantanu Soumya, Oliver Wurl
The Suppression Of Ocean Waves By Biogenic Slicks, Nathan J. M. Laxague, Christopher Zappa, Shantanu Soumya, Oliver Wurl
Faculty Publications
Surface waves are significantly damped by biogenic surfactants which accumulate at the ocean's surface from the high latitudes to the tropics. The growth, development, and breaking of short wind-driven surface waves is a key mediator of the air-sea exchange of momentum, heat, and trace gases consequently, the effect of surfactant compounds in the uppermost millimeters of the ocean in damping short surface waves bears on earth's climatic processes. The mechanisms through which surfactants suppress waves have been studied in great detail through careful laboratory experimentation in quasi one-dimensional wave tanks. However, the spatial scales over which this damping occurs in …

The term “offshore” with regards to aquaculture has hitherto encompassed various perspectives, including technology, geographic location, legal jurisdiction, and more. To resolve the ambiguity in this term and understand its implications for current and future aquaculture development, “offshore” should be resolved into two separate metrics: distance from shore and energy exposure. The United Nations Convention on the Law of the Sea (UNCLOS) distinguishes between internal waters, territorial sea, contiguous zone, exclusive economic zone (EEZ), and the high seas, but currently has no precise definition for “offshore” in its provisions, and therefore no applicable laws pertaining to “offshore” aquaculture. Regulating a …

Master Narratives Surrounding Rural Emerging Adult Migration: Resources For Postsecondary Decision-Making In Rural Communities, Cindy Hartman, Jayson Seaman, Andrew D. Coppens, Erin H. Sharp, Sarah Jusseaume
Faculty Publications
This study examined the cultural messages informing postsecondary decision-making processes surrounding emerging adult migration from/to a predominately rural state in the northeastern U.S. Utilizing an ecological approach to sampling, this study used 27 interviews and 5 focus groups of stakeholders working in educational, employment, and quality of life sectors. Narrative analysis yielded evidence of a predominant master narrative of migration as a developmental requirement during emerging adulthood. Stakeholders spoke of normative and prescriptive expectations that emerging adults particularly in rural areas orient their plans and decision-making around, including leaving their home communities for developmental reasons. Implications for emerging adult development …

Modern calcifying marine organisms face numerous environmental stressors, including overfishing, deoxygenation, increasing ocean temperatures, and ocean acidification (OA). Coastal marine settings are predicted to become warmer and more acidic in coming decades, heightening the risks of extreme events such as marine heat waves. Given these threats, it is important to understand the vulnerabilities of marine organisms that construct their shells from calcium carbonate, which are particularly susceptible to warming and decreasing pH levels. To investigate the response of four commercially relevant bivalve species to OA and differing temperatures, juvenile Mercenaria mercenaria (hard shell clams), juvenile Mya arenaria (soft shell clams), …

Globally, winter temperatures are rising, and snowpack is shrinking or disappearing entirely. Despite previous research and published literature reviews, it remains unknown whether biomes across the globe will cross important thresholds in winter temperature and precipitation that will lead to significant ecological changes. Here, we combine the widely used Köppen–Geiger climate classification system with worst-case-scenario projected changes in global monthly temperature and precipitation to illustrate how multiple climatic zones across Earth may experience shifting winter conditions by the end of this century. We then examine how these shifts may affect ecosystems within corresponding biomes. Our analysis demonstrates potential widespread losses …

Hydrodynamic Exposure – On The Quest To Deriving Quantitative Metrics For Mariculture Sites, Oliver Lojek, Nils Goseberg, Heidi Moe Føre, Tobias Dewhurst, Thea Bölker, Kevin Gerald Heasman, Bela H. Buck, David W. Fredriksson, Samuel Rickerich
Faculty Publications
This work attempts to define metrics for hydrodynamic exposure, using known oceanographic variables to provide a universal site assessment method for mariculture structures. Understanding environmental conditions driving open-ocean mariculture siting is crucial in establishing consistent ocean governance, minimizing adverse environmental impacts, and facilitating economically sustainable farm operations. To provide a metric of oceanic conditions and associated requirements for structural design and operation of aquaculture systems, six Exposure Indices (EI) are proposed that consider physical energy levels related to hydrodynamic forces at a site. Four of the proposed indices consider only environmental conditions, while the other two also consider the dimensions …
Finite Sum Of Integral Operators From The Fractional Cauchy Spaces To Bloch-Type And Zygmund-Type Spaces, Rita A. Hibschweiler, Ajay K. Sharma
Finite Sum Of Integral Operators From The Fractional Cauchy Spaces To Bloch-Type And Zygmund-Type Spaces, Rita A. Hibschweiler, Ajay K. Sharma
Faculty Publications
The family of fractional Cauchy transforms, defined on the open unit disc in the complex plane, is of classical and modern interest. Membership of an analytic function in the family is determined by the requirement that the function can be expressed as an integral of a certain kernel against a complex Borel measure on the disc. Such an integral representation imposes a growth condition on the function and its derivatives. This exposes a connection between the families of Cauchy transforms and familiar spaces of analytic functions, such as the Bloch spaces and the Zygmund space. The notion of a composition …

Footprint Tools Tiptoeing Towards Nitrogen Sustainability, James N. Galloway, Elizabeth A. Castner, Elizabeth S M Dukes, Jessica Fox, Allison M. Leach
Faculty Publications
As we face multiple environmental crises (e.g. climate change, nutrient pollution, freshwater scarcity), there is often a disconnect between an entity’s activities and the pollution resulting from that activity. Footprint tools help address this disconnect. They are effective in educating people, institutions and communities on how their resource use results in environmental pollution and what we can do to moderate that pollution. These tools connect an entity’s activities with the associated pollution. Footprint tools are also constantly evolving. As we better understand how to best estimate emissions—especially from sources further removed like those from the supply chain—the guidance and methods …

Environmental Sensitivity Index (Esi) Feasibility Study Of All-Hazards Indices Expansion, Research Planning, Inc
Coastal Response Research Center
Environmental Sensitivity Index (ESI) products are developed by the National Oceanic and Atmospheric Administration (NOAA) to support planning for and responding to coastal oil and chemical spills. ESI data describe a variety of coastal resources that are at risk from oil spills that include sensitive shorelines (e.g., marshes, tidal flats), biological resources (e.g., birds, shellfish beds), and human-use resources (e.g., public beaches, water intakes). ESI maps and datasets include shoreline types that are ranked according to their sensitivity to oil and chemical spills. This index was the original focus of ESI maps and has been a standard for industry and …
Carbon Cycling Driven By Disturbance In A Tropical Freshwater Ecosystem, Alicia Dixon
Carbon Cycling Driven By Disturbance In A Tropical Freshwater Ecosystem, Alicia Dixon
Master's Theses and Capstones
Streams are hotspots for biogeochemical cycling in freshwater ecosystems and act as transformers for elements moving throughout their watersheds. Small watersheds in particular are the ideal natural laboratory for exploring how freshwater systems react to inputs and outputs of carbon, nitrogen, and other trace elements. Carbon cycling occurs throughout watersheds at different scales and through different pathways. Organic matter enters a stream from surrounding terrestrial environments, and is subsequently consumed by microbes, macroinvertebrates, and other freshwater organisms. The fate of organic matter in a stream is diverse, but some common pathways include emission as carbon dioxide through metabolic processes, movement …
Liquefaction Mitigation Of Sands With Plastic Fines Via Microbial Induced Partial Saturation, Maya Norris
Liquefaction Mitigation Of Sands With Plastic Fines Via Microbial Induced Partial Saturation, Maya Norris
Master's Theses and Capstones
Microbial Induced Partial Saturation (MIPS) is a sustainable and cost-effective approach to mitigate liquefaction; however, more research needs to be done to apply MIPS to a variety of different soil types and conditions. The investigation consisted of running a series of undrained strain-controlled cyclic Direct Simple Shear (DSS) tests on fully saturated samples with varying non-plastic fine and plastic fine content. Some tests have been conducted on MIPS-treated samples; however, more tests are needed to verify the results. Previous investigations have been conducted to evaluate the pore water pressure response of sands with added non-plastic fines with and without MIPS …
Environmental Change And Population Dynamics Of Small Mammals In Northern Alaska, Jess K. Steketee
Environmental Change And Population Dynamics Of Small Mammals In Northern Alaska, Jess K. Steketee
Doctoral Dissertations
Rodent populations at northern latitudes undergo cyclic dynamics characterized by high amplitude interannual fluctuations every 3-5 years. Population cycles have puzzled mammalogists for over a century and disentangling their drivers remains a central goal. Understanding which factors drive rodent populations and how these dynamics might change with warming is essential for predicting the impacts of climate change on arctic ecosystems as herbivore pressure shapes plant community composition, soil nutrient availability and carbon concentrations. My research focused on potential drivers of brown lemming (Lemmus trimucronatus) and tundra vole (Microtus oeconomus) population fluctuations in Arctic Alaska. I combined field techniques with laboratory …

Innovative Approaches To Dna-Based Materials: Development Of Bottlebrush Polymers, Supramolecular Hydrogels, And Psoralen-Enhanced 3d Printing Of Dna Bioinks, Nicholas Pierini
Doctoral Dissertations
This thesis explores innovative approaches to enhancing the functionality and applications of DNA-based materials through the development of DNA bottlebrush polymers (BBPs), DNA-intercalating supramolecular hydrogels (DISHs), and psoralen-based 3D printing techniques. The first chapter presents the synthesis and characterization of linear and cyclic DNA BBPs using a grafting-to approach. Plasmid DNA (pDNA) is used as the polymeric backbone, grafted with polyethylene glycol (PEG) side chains of varying molecular weights (750 Da, 2000 Da, and 5000 Da) to improve stability and functionality. Achieving high graft densities, up to 24% for mPEG750-CEA, and purifying the PEG-DNA conjugates were significant challenges addressed through …
