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 …

Beaver Pond Geomorphology Influences Pond Nitrogen Retention And Denitrification, Desneiges Murray, Bethany T. Neilson, Janice Brahney

Watershed Sciences Faculty Publications

Beaver ponds are increasingly promoted as a strategy for physical stream restoration, and more recently recognized as natural solutions for excess nonpoint source pollutants, such as nitrogen (N). Beaver ponds facilitate N transformations on the streamscape by increasing sediment-water interactions and creating low and high redox conditions in close proximity. Because beaver ponds vary widely in their geomorphology, the spatial extent of morphological units should dictate the degree of biogeochemical processing. We explore the role of beaver pond geomorphic units in facilitating sediment N transformations using a sediment mass balance approach. We quantified input, output, and transformation of N species …

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 …

Industrialization Of Tall Wheatgrass For Construction Of “Coastal Grass Belt”, Hongwei Li, Qi Zheng, Jianlin Wang, Hongyong Sun, Kexin Zhang, Hongman Fang, Xuerong Xing, Weicai Yang, Xiaofeng Cao, Xiaojing Liu, Haichun Jing, Kang Chong, Zhensheng Li

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 …

Research On Offshore Wind Energy Classification: Bottlenecks And Countermeasures, Chongwei Zheng, Chongyin Li

Bulletin of Chinese Academy of Sciences (Chinese Version)

Offshore wind energy resource is a key support for the “carbon peak and carbon neutrality”. However, offshore wind energy development still faces the international bottleneck of reasonable energy classification, which is urgently needed in the overall arrangement and accurate site selection. Firstly, this study systematically reviewed the research progress of offshore wind energy classification scheme at home and abroad, and analyzed the six aspects that need to be improved in the traditional energy classification scheme: without comprehensive consideration of resource characteristics, environmental risks and cost-effectiveness, without significant regional difference of energy classification, unable to meet the needs of diversified tasks, …

This study evaluates the water quality of three streams in and around Winona, Minnesota, using the macroinvertebrate communities present and chloride levels as indicators. Three upstream samples were taken and thoroughly examined at three different locations: Garvin Brook, Gilmore Creek, and Pleasant Valley Creek. During the snowmelt season, four sets of upstream and one set of downstream water samples were taken from each. The samples were analyzed using a Vernier chloride ion-selective electrode. The Izaak Walton League of America's Save Our Streams invertebrate classification system was used to …

Chemical Analysis Of Morris Water Pollutants Via Electrochemical Detection Methods, Emily Miller

Undergraduate Research Symposium 2023

In small towns like Morris that are surrounded by agriculture, there’s an increased likelihood of contaminants to be present in the water. These commonly include heavy metals and pesticides which, in high enough dosages or prolonged exposure, can quickly become poisonous and harmful with lasting effects for both plants and humans. Throughout our research we have been analyzing the presence, if any, of lead, copper and cadmium as well as the common pesticides atrazine and mesotrione in the water throughout Morris. We look at a variety of samples coming from melted snow (collected throughout Nov. 2022–Apr. 2023), drinking water, and …

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 …

Detection Of A Diverse Endophyte Assemblage Within Fungal Communities Associated With The Arundo Leaf Miner, Lasioptera Donacis (Diptera: Cecidomyiidae), Marie-Claude Bon, John A. Goolsby, Guy Mercadier, Fatiha Guermache, Javid Kashef, Massimo Cristofaro, Ann T. Vacek, Alan Kirk

School of Earth, Environmental, & Marine Sciences Faculty Publications

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 …

Weaving Traditional Indigenous Knowledge And Western Science To Address Pressing Environmental Issues In The Navajo Nation, Abhishek Roychowdhury

Sustainability Seminar Series

The largest Native American tribe in the U.S., the Navajo Nation, faces a humanitarian crisis due to lack of access to clean and safe water resources. Although access to clean water is not a privilege but it is a human right, thirty percent of Navajo residents do not have access to clean running water. Native American households are 19 times more likely than other U.S. households to live without running water. Solutions to water infrastructure that can address this gap are complicated in the arid Southwest where poor groundwater quality, including high salinity, microbial contaminants and metal contaminants, limit available …

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 …

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 …

Water Erosion In The South-West Of Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

The averaged annual direct cost of water erosion to dryland farming in Western Australia is estimated to be $10 million, but the costs are much higher in years of severe summer storms.

Water erosion occurs when water flowing over the land surface moves soil particles downslope. Water erosion is a natural process, but is accelerated under agriculture, especially on cropped land. Water erosion causes loss of topsoil, reduced crop yields, damaged infrastructure, weed dispersal, eutrophication (algal blooms) and silting of dams and natural waterways.
