Geothermal Energy Exploitation And Storage In Coal Field Under The Dual Carbon Goal, Wang Jiyang, Kong Yanlong, Duan Zhongfeng, Zhang Jixiong, Luo Xilian, Huang Yonghui, Luo Naning, Cheng Yuanzhi, Zhou Nan, Zhang Weizun, Pang Zhonghe

Coal Geology & Exploration

The development of geothermal energy in coalfield can not only improve the temperature environment of coal mining, but also turn waste into treasure through the clean utilization of geothermal energy. Especially, it is of great prospect to store energy in the mined-out area of coalfield under the “dual carbon” goal at present. Herein, in this paper, it was estimated that the geothermal reserves in the main coal-bearing areas of China were 1.12 × 10¹⁹ kJ, equivalent to 379.539 billion tons of standard coal, and the recoverable geothermal reserves were 1.71 × 10¹⁸ kJ, equivalent to 56.931 billion tons …

Monitoring Air Quality Post-Environmental Disasters Using Remote Sensing, Abigail Kline

Student Symposium

East Palestine Ohio, is a small town that recently suffered from a train derailment carrying a toxic chemical known as vincyl chloride. In addition to the release of this chemical, particulate matter was ejected into the atmosphere following a controlled explosion of the train. Air pollution a major envirnmental hazard that affects human and non-human life, and so the monitoring pollution is extremely important. Remote sensing may be a viable way to monitor, by using readily available satellite data.

Estimating Supraglacial Melt Lake Volume Changes In West Central Greenland Using Multiple Remote Sensing Methods, Wesley Rancher

Student Symposium

The Greenland Ice Sheet (GrIS) is losing ice mass as the climate warms. Supraglacial melt lakes (SGLs), which are present in the ablation (melt) zone of the GrIS are found to be responsive - and reinforce - changes in glaciological and climatological dynamics. Developing a spatiotemporal model to monitor lake volume change throughout the melt season (late-April through September) can enhance our understanding of subsequent GrIS changes. Supraglacial melt lakes accumulate in volume and in some cases drain to the ice sheet base during the melting season. In this study we utilize Landsat satellite imagery paired with high resolution digital …

The Public Trust Doctrine: Roman Law Roots And Future In Environmental Litigation, Phoebe Liccardo

Honors Theses

The public trust is an ancient and enduring legal doctrine. With roots in Roman law, the public trust persists through English law, and into the United States. Scholars and jurists in the field of Roman and environmental law do not all agree on the history and continuity of the public trust doctrine (PTD). There are those who argue the Roman law introducing a public trust did not assert the same protections present in the doctrine today. Conversely, there are those who believe the Roman law did enshrine similar protections, and further, that it calls for an expansion of PTD in …

Bulletin of Chinese Academy of Sciences (Chinese Version)

Tall wheatgrass (Elytrigia elongata) is a perennial cool-season bunchgrass with high productivity and tolerance to salt and alkali, waterlogging, and drought. Since first introduced into China in 1950s, tall wheatgrass has long been used as a wild parent for distant hybridization with wheat (Triticum aestivum). During 1980s─1990s, a few tall wheatgrass varieties were introduced to China as forage grass, nonetheless, currently they are still not widely cultivated and no variety was certificated. In 2020, Zhensheng Li put forward a proposal to construct “Coastal Grass Belt” on saline and alkaline soils in the Circum-Bohai sea region, which provides an opportunity for …

School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations

The larvae of Lasioptera donacis Coutin feed on fungal communities lining galleries within the mesophyll of leaf sheaths of Arundo donax in an aggregative manner. It has been stated that L. donacis could have established a fundamental symbiotic relationship with one fungus, although the fungal composition of these communities remains unsettled. Using a culture-dependent approach and ITS sequencing, the present work characterizes and compares the fungal communities associated with L. donacis in Eurasia with the endophytes of A. donax in Texas where L. donacis is absent. The 65 cultivable isolates obtained from L. donacis fungal communities were sorted into 15 …

The History And Significance Of Taxidermy Bird Collections In North America: Bgsu's Own Undervalued Collection And Its Future, Kristin Burnside

Honors Projects

Taxidermy, despite its association with the bizarre and outlandish, has a rich history and culture that helped to define post-Civil War America and its pursuit of knowledge and reconnection with nature. With the widespread publication and availability of how-to guides, natural history collecting and taxidermy became accessible to any individual regardless of age, gender, or class. The hobby required physicality and courage to collect unique and interesting specimens, and intellect and creativity to conserve and display them, all of which inherently connected the avocation with respect. With varying levels of success, hobbyists experimented with different chemicals, such as arsenic, in …

Using Integral Projection Models To Explore Management Strategies For Silver Carp (Hypophthalmichthys Molitrix), Cameron Coles, Elizabeth Balas, James Peirce, Greg Sandland, Richard Erickson

Spora: A Journal of Biomathematics

Silver carp (Hypophthalmichthys molitrix) are planktivorous fish that were originally introduced to the United States for use in fish production ponds and have since escaped these enclosures and are invading the Mississippi River Basin. The silver carp invasion of the Illinois River has a myriad of negative effects on native ecosystems. In this paper, we introduce key dependencies that are likely important in the population dynamics of silver carp: length-dependent egg production and density-dependent growth. Using movement data between two adjacent pools of the Illinois River, we conduct numerical simulations to explore the theoretical effect of harvesting and …

How Resilience Is Framed Matters For Governance Of Coastal Social-Ecological Systems, Sarah Clement, Javad Jozaei, Michael Mitchell, Craig R. Allen, Ahjond S. Garmestani

School of Natural Resources: Faculty Publications

Effective governance of social-ecological systems (SES) is an enduring challenge, especially in coastal environments where accelerating impacts of climate change are increasing pressure on already stressed systems. While resilience is often proposed as a suitable framing to re-orient governance and management, the literature includes many different, and sometimes conflicting, definitions and ideas that influence how the concept is applied, especially in coastal environments. This study combines discourse analysis of the coastal governance literature and key informant interviews in Tasmania, Australia, demonstrating inconsistencies and confusion in the way that resilience is framed in coastal governance research and practice. We find that …

Organic Matter Quality Influences Aerobic And Anaerobic Respiration Rates In Peatland Soils, Rachel Shaw, Lauren Bryan, Madison Smith, Christian Lundy, Alexis Koehl, Grace Behrens, Mackenzie Dole, Madeleine O'Donnell

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

The vulnerability of peatland carbon reservoirs to decomposition in a warming climate remains a key uncertainty in Earth System Models. This will be determined in part by the "quality" of the peatland organic matter, i.e. the ease by which it is decomposed by the microbial community. We developed an index of organic matter quality based on the biochemical composition of the peat. The index uses a principal components analysis of proxies based on the carbohydrate composition, hydrolysable amino acids, C:N, pH, and nutrient availability in the peat porewater. The index was compared with measurements of aerobic and anaerobic respiration rates …

Temperature Sensitivity Of Nitrogen Mineralization In Peat From A Southwestern Michigan Bog, Madison Smith, Lauren Bryan, Rachel Shaw, Mackenzie Dole, Madeleine O'Donnell

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

In this study, we measured inorganic nitrogen (nitrate and ammonium) released from peat cores from Miner Lake bog at two temperatures to analyze the impact of climate warming on the peatland nitrogen cycle. We hypothesized a higher nitrogen release in samples incubated at warmer temperatures. Furthermore, previous research indicates shallow peat decomposes faster than deeper peat. Therefore, we hypothesized faster nitrogen mineralization in shallow samples. We collected peat cores from two locations from Miner Lake Bog in Allegan County, Michigan: a plot in the center of the bog and a sedge meadow site near the edge. Two samples for each …

Mixing Regimes In A Cluster Of Seven Maar Lakes In Tropical Monsoon Asia, Milette U. Mendoza, Jaydan I. Aguilar, Karol Sophia Agape R. Padilla, Rey Donne S. Papa, Noboru Okuda

Environmental Science Faculty Publications

The 7 maar lakes of San Pablo are a cluster of small volcanic lakes on Luzon Island; Philippines. These lakes; which are heavily utilized for aquaculture and ecotourism; usually experience fish kills that coincide with the northeast monsoon (NEM). This study explores limnophysical processes; particularly mixing regimes; in the lakes in relation to prevailing monsoons. We monitored monthly vertical and seasonal profiles of water temperature; salinity; conductivity; and dissolved oxygen from October 2016 to December 2018. Three types of mixing regimes were observed among the lakes; which have similar surface areas but different depths: polymixis in the shallowest; warm monomixis …

Impacts Of Urban Renewal On Community Identity And Sense Of Place In Las Cruces, New Mexico, Savannah Lorraine Quintana-Eddins

Geography ETDs

Las Cruces is the second largest city in New Mexico which has experienced exponential growth in the last three decades. The city has been cultivated by a rich history of Native populations, Spanish colonialism, and American democratic government. The culmination of these influences on Las Cruces had much influence on the Mesquite Historic District, the original townsite of Las Cruces. This area is home to many generational families and is adjacent to the downtown Main Street corridor. Downtown was built from the destruction of the Mesquite Historic District caused by waves of urban renewal projects. Through organizing, legislative action and …
