Ocean-Ice Sheet Interactions During Super-Interglacial Mis 31: Comparison Of Rock Magnetic Records From The Scotia Sea (59.1°S) And Fram Strait (76.5°N), Olga Libman-Roshal

Theses, Dissertations and Culminating Projects

The mid-Pleistocene transition (MPT) was a period spanning ~1.2-0.7 Ma when glacial-interglacial cyclicity changed from 41 kyr obliquity paced to 100 kyr eccentricity paced cycles with increased glacial-interglacial contrast post-MPT. Marine Isotope Stage (MIS) 31 was a “super-interglacial” within the MPT and occurred in the recent geological past (1.08-1.06 Ma). During MIS 31, the tectonic configuration resembled the present day, but Earth’s orbital parameters were marked by maximum values of eccentricity and obliquity while atmospheric CO2 remained at pre-industrial levels (below 280 ppm). MIS 31 therefore offers a valuable baseline for testing the impacts of modern anthropogenic CO2 levels combined …

Technoscientific Imaging And The Territorialization Of Ocean Depth, João Afonso Baptista, Pedro Figueiredo Neto, Irus Braverman, Philip Steinberg, Gabriella Palermo, Stefan Helmreich, Melody Jue, John Childs

Journal Articles

Once the last unclaimed solid expanse on Earth, the ocean floor has become one of the most contested spaces in contemporary geopolitics. The data-imagery produced by technoscience serves as the ultimate tool for nations asserting sovereignty in this territorial race. This symposium gathers diverse perspectives on the ongoing expansionist drive on the seabed, drawing inspiration from Abissal——a film-article featuring the Portuguese modern odyssey on the ocean floor that serves as the symposium’s centerpiece. Aligned with modern ocean law, technoscience strives to render ocean depth visible to politics and territorializable for coastal states. However, the submerged prolongations and divisions it proffers …

Indonesia In Brics: A Realist Perspective, Brice Tseen Fu Lee, Kotchaphop Kornphetcharat, Juan Pablo Sims

Journal of Strategic and Global Studies

Indonesia’s 2025 accession to BRICS (Brazil, Russia, India, China, and South Africa) appears at odds with the country’s long-standing bebas-aktif (“free and active”) tradition of non-alignment. This article explains the move through a layered realist approach and a purely theoretical, deductive method. First, the study integrates structural, offensive, and neoclassical realism to clarify four key mechanisms external balancing, hedging, relative gains, and status-seeking. It then maps propositions about what BRICS can offer Indonesia and tests them against existing realist scholarship on middle powers and emerging-power clubs. Analysis shows that BRICS chiefly serves as an external-balancing instrument, reducing Jakarta’s reliance on …

Highly Contaminated Sediments From The Gowanus Canal (New York) Superfund Site: An Environmental Forensic Approach, Michael A. Kruge, Kevin K. Olsen, Eric A Stern, Maria Mastalerz, Albert Permanyer

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The 2.5 km long Gowanus Canal (Brooklyn, NY, USA) is a severely contaminated urban waterway dating from the mid-19th century, listed as a US Environmental Protection Agency (USEPA) Superfund site since 2010. Applying an environmental forensics approach to the extensive USEPA data set, we detect systematic variations in parent PAH ring number distributions in the canal sediments, as well as an extraordinary enrichment in organic carbon. We subjected a supplemental sample set to a more detailed analysis by quantitative pyrolysis-GC-MS, Rock-Eval pyrolysis, and organic petrology. With these sensitive methods, we can confirm the alkyl-PAH fingerprint of coal tar (a legacy …

The Impact Of Green Finance, Trade Openness, And Fossil Fuel Subsidies On Renewable Energy Consumption: A Global And Asia-Pacific Perspective, Alya Ryanti Fitjriyah, Inayati Nuraini Dwiputri

Journal of Environmental Science and Sustainable Development

Fossil fuels are the major source of global emissions, with the Asia-Pacific region being the climate biggest polluter. Despite the global efforts to shift to cleaner energy, fossil fuels still dominate the energy mix. Therefore, renewable energy adoption needs to be encouraged more to improve economic sustainability. The Glasgow Climate Pact emphasises the importance of helping developing countries in addressing the climate change issue through financial support, capacity building, and technology transfer. Hence, this study examines the influence of green finance, open trade, and fossil fuel subsidies on renewable energy adoption in 38 countries from 2017 to 2023. By using …

Environmental Impacts Of Land Use Change In Industrial Areas, Dwi Nowo Martono, Aruminingsih Aruminingsih

Journal of Environmental Science and Sustainable Development

Industrial development in Indonesia has been predominantly concentrated on Java Island, particularly in Karawang Regency, West Java Province. Covering an area of 175,327 hectares, Karawang has been identified as a strategic region for national food security. The Minister of Agrarian Affairs and Spatial Planning designated 95,667.45 hectares of rice fields as protected agricultural land. However, the expansion of industrial and residential areas within the regency poses a significant threat to its role as the national rice granary and to broader food security. As industrial land occupancy increases, the environmental capacity to support rice production and ensure national food security declines. …

A Simulation Study On Effects Of Heifer Excreta On Herbage Yields And Potassium Uptake In Grazing Pasture, T Hakamata

IGC Proceedings (1977-2023)

Two models (a potassium cycling model and an excreta! spatial dispersion model) were constructed to clarify how biased dispersion of potassium(K) and herbage yields occur in a pasture. 18 cases [ ( unexcreted + (urine, dung) x 4 excreted months) x (grass + legume)] were simulated by the K cycling model to obtain standing crops of K and herbage at the end of a growing season. The standing crops per 1 m2 were calculated on all the quadrats in the pasture by using the excreta! dispersion model. The standing crops in each of 18 cases were assumed to be normally …

Experienced Latinx Urban Gardeners In San Jose, Ca, Offer Strategies For Climate Justice And Resilience, Claudia S. Damiani Fontana

Master's Theses

Low-income and underinvested communities will be disproportionately affected by climate change due to limited resources, inadequate infrastructure, and insufficient support systems. Urban gardeners are responding to the need to adapt to new climate conditions while sustaining their food sources and cultural practices. Many have adapted thanks to local interventions led by the government and non-profit agencies. For this study, I partnered with La Mesa Verde (LMV), a gardening and food justice program that works with low-income Latinx families in San José, and I documented the contributions of experienced Latinx gardeners, especially those with agricultural backgrounds, to climate-resilient gardening in San …

Citizen Science Helps Monitor Urban Biodiversity: An Interactive, Data-Driven, And Open-Source Perspective, Katie Slack

Geography ETDs

Story maps, a powerful tool for communicating environmental narratives, are often commercial and lack many interactive functions. We integrate a data-driven and interactive geovisualization within an open-source story map created from high-attribute citizen science datasets. This story map creates a backend programming infrastructure for accessible, open-source science communication tools. Our story map intuitively communicates the findings from our web map application (app) portion of the story map to the public and helps reveal findings from the iNaturalist datasets. Albuquerque, New Mexico, United States is a demonstrative case study, but our tools can be flexibly adapted to other cities. Geovisualizations revealed …

Nitrogen Fixation In Pampinifervens, A New Species-Rich Genus Of Aquificaceae That Inhabits A Wide Ph Range In Terrestrial Hot Springs., Marike Palmer, Nancy O. Nou, Lara A. Turello, Carolyn E. Power, John C. Ong, Jonathan K. Covington, Dengxun Lai, Xavier Mayali, Anna-Louise Reysenbach, Yan-Ling Qi, Jeremy A. Dodsworth, Yitai Liu, Multiple Additional Authors

Center for Life in Extreme Environments Publications

Members of the Aquificota play important roles in hydrogen, sulfur, and carbon cycles in geothermal systems as ubiquitous and abundant chemolithoautotrophs; however, their roles in the nitrogen cycle are poorly defined. Here, we show that Aquificaceae isolate T-2 from Tengchong, China, fixes nitrogen based on growth with dinitrogen as the sole nitrogen source and incorporation of N atoms when grown with N. We further show evidence that suggests its nitrogen fixation (nif) genes are transcribed in situ in a nearby spring. We propose the name Pampinifervens diazotrophicum gen. et sp. nov., with strain T-2 (= JCM 35475 = DSM 116324) …

Soft Power: Brics Cultural Diplomacy And The Rebalancing Of Global Narratives, Brice Tseen Fu Lee, Kotchaphop Kornphetcharat, Juan Pablo Sims

International Review of Humanities Studies

BRICS has broadened its agenda beyond finance to cultivate soft power through coordinated cultural diplomacy. Examining official statements, press releases, and scholarly commentary on the bloc’s flagship film, sports, and ministerial initiatives, this article shows that cooperation is advancing from one-off spectacles toward structured, recurring institutions. Findings indicate two simultaneous dynamics: outwardly, BRICS venues amplify Global-South perspectives that diversify international cultural flows; inwardly, member states use the same platforms to signal national prestige, revealing persistent status competition. The result is an early but uneven cultural architecture—one that counters Euro-Atlantic narrative dominance yet has not crystallized into a fully coherent BRICS …

Advancing Diamond Quantum Sensors: Isotropic Flux Concentrators And Phase Noise Mitigation, Maziar Saleh Ziabari

Optical Science and Engineering ETDs

Two methods for improving the sensitivity of nitrogen vacancy quantum sensors in diamond are explored. First, by passively concentrating the magnetic flux, three orthogonally oriented ferrite truncated cone pairs amplify the field isotropically by 19 times, allowing measurement of Earth's field without a bias field and increasing sensitivity. Through thorough analysis, modeling and tuning a novel 3-dimensional flux concentrator system, we achieve a fractional standard deviation of less than 1% anisotropy and quantify minimal deadzones and ambient temperature-limited variations below 40 nT/hour. Second, we characterize, model and calculate phase noise in NV experiments, which in NV sensors is effectively indistinguishable …

How Effective Are Engineered And Non-Engineered Riparian Forest Restoration Projects In Providing Salmonid-Quality Habitat In The San Francisco Bay Area?, Alexander Ivanov

Master's Theses

Streams and their riparian zones in the San Francisco Bay Area have been degraded, severely harming salmonid populations in the region. Ecological restoration is a common approach to return stream function. Such restoration projects vary widely in intensity, from low-impact vegetation removal/planting to highly engineered projects involving structures and grading. This research investigated the effectiveness of streams restored using engineered versus non-engineered solutions in supporting salmonid habitat viability in San Francisco Bay Area streams. Fourteen streams, seven from each of the two types of restoration, were sampled in the wet and dry season in 2024, three times each season. Data …

Berl, Lexi Galiardi, Shelby Perry, Tom Butler, Neil Carter, Joseph W. Hinton, Axel Moehrenschlager, Emily Carrollo, Rana Bayrakcismith, Jeremy T. Bruskotter

Michigan Tech Publications

Pumas (Puma concolor) are among the species identified as having the potential to enhance ecosystem function. Previous research highlights sufficient ecological habitat to support pumas in the eastern United States; however, their reintroduction requires social and institutional support as well. To this end, we conducted research to assess attitudes about puma reintroduction among key constituencies like hunters, rural residents, and young people. We sampled 2756 respondents across seven states (Massachusetts, Maine, New Hampshire, New York, Pennsylvania, Vermont, and West Virginia). Ratios of strong support (for puma reintroduction) to strong opposition across states ranged from 4:1 to 13:1, and support outweighed …

Passive Verb Morphology In Arabic And Faifi Dialect, Essa Salman Alfaifi Dr.

Journal of Arabic Sciences and Humanities

The formation of passive verbs in Arabic is uniquely challenging due to its complex structure and dialectal variations. While Classical Arabic (CA) and Modern Standard Arabic (MSA) adhere to non-concatenative rules of internal vowel modification of the active stem, some dialects use different strategies such as affixation or reflexive pronouns with no modification to the stem. However, despite previous studies on Arabic verbs, the passive verb construction remains insufficiently explored. This paper aims to participate in addressing this gap by detailing the passive verb morphology in the Faifi dialect (FD) and comparing it with CA/MSA. The properties of passive verbs …

This study use Delphi and Analytic Network Process methodologies, grounded in the perspectives of regulators, academics, experts, and practitioners in the green economy, to identify the determinants of green financial policies, revealing that fiscal instruments are of paramount importance. Furthermore, both the case and the respondents are Indonesian. This underscores the necessity of instituting incentives in environmentally sustainable sectors and disincentives in carbon-intensive industries. Therefore, the suitable allocation of green budgets within fiscal policy is essential for addressing market failures and expediting …

Assessing Climate Vulnerabilities In Rural And Low-Income Regions: A Case Study Of The Western Upper Peninsula, Mercedes Asamani, Chelsea Schelly

Michigan Tech Publications

Low-income and rural regions may be more vulnerable to the impacts of climate change because they face challenges in accessing resources and systemic exclusion from climate planning coupled with other geographical, geological, and social factors. Climate vulnerability assessments (CVAs) offer a logical framework for assessing the potential impacts of climate change on socio-ecological systems and provide a scientific basis for developing adaptation strategies. Using secondary data from scholarly papers, online publications, government documents, official reports, and relevant news items, the study investigates Michigan’s Western Upper Peninsula’s (WUP) vulnerability to climate change and climate variability. The study is guided by a …

Ecological Experiences And Perceptions Of Small-Scale Gillnet And Purse Seine Fishers On Seabirds And Other Non-Target Taxa In The Humboldt Current System, Chile, Cristián G. Suazo, Cristóbal Anguita, Jaime Ojeda, Guillermo Luna-Jorquera, Maritza Sepúlveda, Oliver Yates

Marine Ornithology

Strategies to reduce the negative impacts of fisheries on ecosystems often come into conflict with fishers who have different experiences with, and perceptions of, biodiversity compared to policy makers and fisheries managers. We interviewed 800 fishers along 2400 kilometers of the Humboldt Current System (HCS) coast, assessing fishers’ perceptions of the impacts of marine predators on fishing and their proposals to reduce conflicts with small-scale net fisheries. Vessel captains saw seabirds as positive indicators of fish presence along the HCS (mean probability 62.7%). In contrast, sea lions were perceived negatively, affecting catches for all fishers and causing fishing gear damage …

Diet Assessment And Vulnerability Of White-Faced Storm Petrel Pelagodroma Marina Within A Warming Hotspot, Madhuli Karmalkar, Lauren Roman, Farzana Kastury, Fernando Arce, Kerrie M. Swadling

Marine Ornithology

Shifts in zooplankton communities due to changing ocean climate can affect foraging patterns among planktivorous seabirds. To better understand seabird response to environmental change in Bass Strait, southeast Australia, we investigated the prey species and 16 elements in prey and feathers of the planktivorous White-faced Storm Petrel Pelagodroma marina. The krill Nyctiphanes australis was the most abundant prey species, followed by several species of post-larval fish; otherwise, the species appeared to be a generalist feeder. Element concentrations of feathers were not significantly influenced by dietary composition. Likewise, element concentrations did not significantly differ between major prey species, confirming that the …

Lesser Noddy Anous Tenuirostris Migration From A Non-Breeding Area In The Northern Maldives To A Breeding Site In The Seychelles, A. Farhath Ali, Richard A. Phillips, R. Charles Anderson

Marine Ornithology

The Lesser Noddy Anous tenuirostris occurs in large numbers in the northern Maldives during the northeast monsoon season (December to April). These birds do not breed in the Maldives, but their breeding site(s) are unknown. We attached GPS Argos satellite transmitters to seven Lesser Noddies roosting on Gallandhoo Island (Haa Alifu Atoll, northern Maldives) on 25 March 2022. Only one transmitter provided data, but it tracked the migration of one Lesser Noddy to the Seychelles, where the bird first roosted on the island of Poivre before moving to the large nesting colony on Cousine. The tracked bird departed the Maldives …
