A Two-Stage Approach To Integrate Vessel Geo-Tracking Data And Logbooks For Monitoring Fishing Activity Of Coastal Fisheries In Waters Off Northwestern Taiwan, Yi-Jou Lee, Nan-Jay Su, Cheng-Hsin Liao, Wei-Chuan Chiang, Chun-Huei Li

Journal of Marine Science and Technology–Taiwan

Catch and fishing effort data are fundamental information to stock assessment and fisheries management, but difficult to obtain without the support of administration and sound fishery data collection system. This study integrated various sources of data from a simplified vessel geo-tracking system and logbooks from interviews with captains of coastal gillnet fisheries. We developed a two-step approach based on hierarchical cluster analysis to characterize the operation patterns and infer the fishing activities of the fishery. Results showed that the fishing effort in terms of operation duration could be estimated precisely for various vessel sizes, with catch composition and harvest information …

Permian Dust And Its Relevance To Modern Climate Change, Lynn Soreghan

Sustainability Seminar Series

Dust/loess is well known as both an archive of climate and agent of climate change for Earth’s recent record. But dust deposits are increasingly recognized in Earth’s deep-time record, especially from the Permian. Thick dust deposits occur in the U.S., and elsewhere (e.g. France) along the paleoequator. Dust deposition pulsed on a glacial-interglacial timescale, and was sourced from regions that included the equatorial Central Pangaean Mountains. Notably, the voluminous atmospheric dust stimulated productivity in the marine and terrestrial biosphere, thus affecting carbon cycling and source-rock development. Recent recognition of extraordinarily thick dust deposits in the Permian of Oklahoma have spawned …

A Green-Gray Path To Global Water Security And Sustainable Infrastructure, Charles J. Vörösmarty, Ben Stewart-Koster, Pamela A. Green, Edward L. Boone, Martina Flörke, Günther Fischer, David A. Wiberg, Stuart E. Bunn, Anik Bhaduri, Peter B. Mcintyre, Claudia Sadoff, Hongxing Liu, David Stifel

Advanced Science Research Center

Sustainable development demands reliable water resources, yet traditional water management has broadly failed to avoid environmental degradation and contain infrastructure costs. We explore the global-scale feasibility of combining natural capital with engineering-based (green-gray) approaches to meet water security threats over the 21st century. Threats to water resource systems are projected to rise throughout this period, together with a significant expansion in engineering deployments and progressive loss of natural capital. In many parts of the world, strong path dependencies are projected to arise from the legacy of prior environmental degradation that constrains future water management to a heavy reliance on engineering-based …

Bioplastics In The Consumer Market, Elena Strom

Master of Science in Environmental Sciences and Management Projects

The global production and mismanagement of plastic has led to plastics deposited and scatted across marine environments. Conventional plastic, which most Americans encounter every day, is produced from fossil fuels and lacks the ability to fully break down upon disposal, breaking down into microplastics that can remain in the natural environment for hundreds of years. Moving away from petroleum-based plastics could lead to a reduction in greenhouse gas emissions and decrease plastic particles in the ocean. Based on existing literature, there are three biopolymers that could serve as replacements to conventional plastics in the marketplace. These biopolymers are seen as …

Sources And Aftermaths Of Pipeline Related Leaks And Spills, Justin Smith

Symposium of Student Scholars

The escape of oil and other hazardous materials have been shown to pollute and destroy ecosystems. As an aspiring chemist, I am adamant about the secure handling and transportation of oil and other hazardous materials. In the past, researchers have concentrated on oil’s high viscosity. Oil’s high viscosity physically smothers wildlife, affecting their ability to continue critical functions such as respiration, feeding, and thermoregulation. My research focuses on the source of these oil spills, as well as natural gas leaks, for the purpose of risk assessment. In addition, I compare recovery efforts based on the cause of the leak/spill, the …

2021 Fall Engr333 Project Assignment, Matthew K. Heun

ENGR 333

The Fall 2021 ENGR333 project focused on the sustainable housing and featured a partnership with Habitat for Humanity of Kent County.

I asked the students “What is the expected carbon emissions savings of the [Habitat for Humanity] carbon footprint build house?” And “If the carbon footprint build house is not carbon-neutral, you must answer a second question: How can carbon emissions be reduced by a further 20%?”

Calvin’s PR office followed the students’ work throughout the semester. At the end of the semester, the project was featured on Calvin’s News and Stories site with an article by Matt Kucinski …

University Sustainability Initiatives Impact On The Surrounding Areas Economy, Sara Kathleen Saucedo

Student Theses and Dissertations

The preservation of the environment depends on sustainability initiatives. Universities influence policy through their impact on their surrounding communities. Universities should, therefore, place a higher priority on campus sustainability efforts. This study examines how universities’ sustainability initiatives impact local area economy. Using data reported by various governmental agencies, I construct a sustainability index based on university initiatives in energy, green buildings, food waste, permaculture, water use, recycling, sustainability council, and AASHE. I model the impact of universities on the local economy using this index and other institutional characteristics. I define the local area economy as effects on poverty rates, unemployment, …

“Surviving And Growing Up With Illegal Status”: The Analysis Of Socio–Economic Household, Potential Conflict, The Environmental Damage, And Vulnerability Of Local Community To Disaster, Sofyan Syahnur, Yossi Diantimala

Journal of Sustainable Mining

This study aims to analyze, from social-economics and environmental perspectives, how illegal gold mining survives and grows with its illegal status. Generally, illegal mining has a positive impact on the socio-economy of all parties involved. However, mining activities cause environmental damage and pollution so that the local community is vulnerable to disaster and potential conflict. This research was conducted at an illegal mining site in Aceh, the western province of Indonesia. To describe the primary data, it employs a descriptive qualitative method. The purposive sampling method is used to select key informants. The results show an increasing income of all …
