Deep Learning-Based Burned Area Mapping Of California Wildfires Using Sentinel-2 And Landsat-8 Imagery Enhanced With Super-Resolution Techniques, Youngmin Seo, Seung Hee Kim, Menas Kafatos, Jinsoo Kim, Yangwon Lee

Institute for ECHO Articles and Research

The increasing frequency of wildfires under a changing climate has led to extensive ecosystem destruction, highlighting the need for reliable burned area assessment using satellite imagery. Single-satellite data are constrained by observation gaps and interference from smoke and clouds, whereas multi-satellite data fusion can mitigate these limitations. Nonetheless, the fusion techniques still encounter challenges such as spatial information loss from resolution differences and cross-satellite domain mismatch. This study presents a burned area mapping framework that integrates super-resolution (SR) with transfer learning to address spatial and domain gaps in multi-satellite data. Specifically, Landsat-8 imagery is super-resolved to 7.5 m resolution, and …

2026 Final Unreclaimed Sites Quality Assurance Project Plan (Qapp), Pioneer Technical Services, Inc.

Silver Bow Creek/Butte Area Superfund Site

Unreclaimed sites exist within the Butte Priority Soils Operable Unit (BPSOU) that could pose a threat to human health or surface water quality due to the presence of historical mine waste. Although many source areas have been previously reclaimed, areas still exist in which soil has not yet been evaluated; such sites may provide a pathway for human exposure or impact surface water quality via stormwater runoff. These Unreclaimed sites will be evaluated in accordance with Appendix D, Attachment C, Section 8.0 of the BPSOU Consent Decree (referred to herein as CD) (EPA, 2020a).

Insufficiently Reclaimed sites exist within the Butte Priority Soils Operable Unit (BPSOU) that could pose a threat to human health or surface water quality due to the exposure of historical mine waste. Although many source areas have been previously reclaimed, areas exist where reclamation was completed prior to the establishment of the Butte Hill Revegetation Specifications (BHRS) or reclaimed areas that have failed consecutive Butte Reclamation Evaluation System (BRES) inspections and now fall into either the Insufficiently Reclaimed or Reclamation Improvement category. In all these cases, additional work is required to comply with the BHRS to ensure the cap remains …

Final 2022 Insufficiently Reclaimed Sites Sampling: Bres No. 16 Site Evaluation Summary Report, Pioneer Technical Services, Inc.

Assessment Of The Radionuclide Concentration Levels Of Water And Sediments Along The Mara River, Gasper Kachenge, Abubakary Salama, Abdalah Kileo, Furaha Chuma

Tanzania Journal of Science

For many years, several factors have impacted the water quality of the Mara River, including population growth, agricultural expansion, livestock keeping, mining, and industrial activities. These factors have intensified water pollution and climate change effects around the river. While previous studies have mainly focused on assessing heavy metal pollution risks on the Mara River, this study evaluates the concentration levels of radionuclides in boreholes, water, and sediments along the river and its tributaries. Naturally occurring radioactive materials, including 226Ra, ²³²Th, and ⁴⁰K, were evaluated. A high-purity germanium radiation detector (HPGe) with a coaxial detector system coupled with Gamma Vision software …

Quantitative Mapping And Mitigation Of Light Pollution At Erau, Desireé Robinson, Marcus Flesher, Axon Deadrick, Conner Callahan, Jarrett Usui, Josef Kaelin, Douglas Griswold, Raiden Keefer, Harrison A. Zimmermann, Cole Gresham, Maya Curtis, Ahnika Gee

Discovery Day - Daytona Beach

Light pollution is an increasingly urgent environmental and public safety concern that affects energy costs, astronomical research, ecological systems, human health, and aviation. At Embry-Riddle Aeronautical University (ERAU), artificial lighting from campus infrastructure and adjacent airport operations contributes to elevated skyglow, limiting the performance of the university’s 1-meter telescope and degrading the nighttime environment. This project seeks to quantitatively map and analyze light pollution across the ERAU Daytona Beach campus using custom-built Sky Quality Meters (SQMs) integrated with environmental sensors and mounted on an unmanned aerial system (UAS). By collecting calibrated sky brightness measurements at multiple altitudes and geospatial coordinates, …

Polymer Degradation And Their Environmental Impact, Addison Orr, Vanessa Gilbert

Discovery Day - Daytona Beach

Synthetic polymer material usage has increased significantly within the last several decades due to their durability, resistance to mechanical wear, low density, and inexpensiveness. Despite these advantages, most synthetic polymers are not biodegradable and instead undergo slow degradation processes. The processes are multifaceted, involving physical, chemical, and biological mechanisms influenced by material properties and environmental conditions, such as soil, light, temperature, and moisture levels. As a result, the polymers break into microplastics and contaminate air, water, and soil, posing risks to human health and surrounding ecosystems. Additionally, polymer degradation can release harmful substances that disrupt food chains and can lead …
