The intersection between the Mid-Atlantic Ridge and Iceland hotspot provides a natural laboratory where the composition and dynamics of Earth's upper mantle can be observed. Plume-ridge interaction drives variations in the melting regime, which result in a range of crustal types, including a series of V-shaped ridges (VSRs) and V-shaped troughs (VSTs) located south of Iceland. Mantle upwelling beneath Iceland dynamically supports regional bathymetry, and its variations may lead to changes in the height of oceanic gateways, which in turn control the flow of deep water on geologic timescales. Expeditions 384, 395C, and 395 recovered extensive successions of basaltic crust …

Ferrate(Vi) Transformation Of Nitrogen In Secondary Wastewater Effluent: Implications For Water And Nutrient Management, Qiufeng Lin, Zepei Tang, Hussein I. Abdel Shafy, Yang Deng

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Ferrate(VI) is a promising chemical agent for wastewater treatment. While targeting various contaminants, it can inevitably react with different water matrix constituents such as nitrogen (N) species. However, the reactions of ferrate(VI) with wastewater N compounds remain poorly understood. This study explores ferrate(VI)-mediated transformations of different N species in a secondary wastewater effluent. Ferrate(VI) oxidation minimally abated total dissolved nitrogen (TDN), while oxidizing dissolved organic nitrogen (DON) into dissolved inorganic nitrogen (DIN), primarily nitrate nitrogen (NO3--N), without noticeably altering ammonia nitrogen (NH3-N) levels. Consequently, ferrate(VI) treatment increased the fraction of bioavailable, soil-leachable NO3--N while lowering the portion of less bioaccessible …

Here, CFD simulates the flow field and PM2.5 dispersion, using in-situ observations for turbulence model selection. GIS quantify architecture morphology parameters to establish accurate CFD boundary conditions, ensuring simulations reflect real-world conditions and precise …

Hydrogen Diffusion Into Water And Cushion Gases – Relevance For Hydrogen Geo-Storage, Quoc Truc Doan, Alireza Keshavarz, Peter Behrenbruch, Stefan Iglauer

Research outputs 2022 to 2026

Hydrogen (H2) has been recognized as a promising solution to reduce carbon dioxide (CO2) emissions. H2 is considered a green energy carrier for energy storage, transport, and usage, and it can be produced from renewable energy resources (such as solar, hydropower, and wind energy). However, H2 is a highly diffusive compound compared to other natural gases, raising concerns about the possibility of H2 loss in geo-storage (e.g. in underground geological formations such as depleted oil/gas reservoirs, aquifers or shale formations) or H2 leak via pipelines when blending H2 with natural gas in existing pipeline systems. Thus, understanding H2 diffusion in …

Effects Of Fire Recurrence And Severity On Mediterranean Vegetation Dynamics: Implications For Structure And Composition In Southern Spain, Macarena Ortega, Ángel Lora, Larissa Yocom, Rafael Zumaquero, Juan Ramón Molina

Wildland Resources Faculty Publications

Most Mediterranean ecosystems have been profoundly shaped by wildfires, driving the evolution of plant species. Through photo interpretation and field inventories, this research assessed vegetation dynamics from 1984 to 2021, examining how fire severity and recurrence, key fire regime variables, influenced changes in structure and woody species diversity. Using two burn scars (1988 and 2006), we identified four scenarios dominated by Pinus pinea tree species: control (unburned), areas burned once (either in 1988 or 2006), and twice (in both 1988 and 2006).

Areas affected by two high-severity fires experienced the most pronounced expansion of dense shrubland. However, when fire severity …

Restoring The AhupuaʻA: Community-Based Resource Management And Resilience In KauaʻI, Jeffrey W. Walbridge Jr.

Environmental Studies Senior Theses

This thesis analyzes Kauaʻi’s evolving resource management practices, examining the intersections of historical governance frameworks, modern legal systems, and indigenous knowledge. Utilizing the traditional ahupuaʻa system, Kauaʻi’s approach once promoted holistic stewardship across water, land, and energy resources. However, colonial policies, corporate influence, and economic pressures have gradually shifted this framework toward a market-driven model, often prioritizing tourism and development over ecological resilience. Key policy shifts as they fight to return to an ahupua'a based model – from the Great Mahele’s introduction of private land ownership to water diversions for plantation agriculture – help examine how these changes continue to …
