Microbes and Climate Change01:27

Microbes and Climate Change

Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...
Microbes and Methanogenesis01:26

Microbes and Methanogenesis

Methanogenesis is a critical microbial process in anaerobic ecosystems responsible for the biological production of methane, a potent greenhouse gas and valuable biofuel. This metabolic pathway is primarily facilitated by methanogenic archaea, which thrive in anoxic environments such as wetlands, sediments, and animal gastrointestinal tracts. The absence of oxygen in these habitats prevents aerobic respiration, thereby favoring alternative biochemical pathways for organic matter degradation.In...
The Carbon Cycle01:14

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.
Acid Mine Drainage01:19

Acid Mine Drainage

Mining activities that disturb sulfide-rich rocks, particularly those containing pyrite (FeS₂), initiate a cascade of geochemical and microbiological processes with serious environmental implications. When exposed to air and water, pyrite undergoes oxidation, releasing sulfate, ultimately forming sulfuric acid and mobilizing heavy metals into surrounding water systems. This phenomenon, known as acid mine drainage (AMD), results in low pH waters laden with toxic elements that threaten aquatic...
Metabolism of Chemolithotrophs01:15

Metabolism of Chemolithotrophs

Chemolithotrophs are microorganisms that obtain energy by oxidizing inorganic molecules such as hydrogen gas (H₂), ammonia (NH₃), reduced sulfur compounds (H₂S, S²⁻), and ferrous iron (Fe²⁺). Unlike heterotrophic organisms that rely on organic carbon, chemolithotrophs transfer electrons from these inorganic donors to the electron transport chain (ETC), generating a proton motive force (PMF) that drives ATP synthesis through oxidative phosphorylation. However, because inorganic electron donors...
The Sulfur Cycle01:22

The Sulfur Cycle

Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...

Area of Science:

  • Environmental Science
  • Atmospheric Chemistry
  • Geosciences

Background:

  • Methane emissions from underground coal mines contribute significantly to greenhouse gases.
  • Accurate measurement of these emissions is crucial for effective mitigation strategies.
  • Existing monitoring methods have limitations in coverage and precision.

Purpose of the Study:

  • To compare the effectiveness of vehicle-based, airborne, and sUAS (small uncrewed aerial system) near-infrared spectrometers for measuring methane emissions from Kentucky coal mines.
  • To assess the accuracy and uncertainty of different measurement platforms against established reporting programs.
  • To highlight the potential of vehicle-based surveys for improved methane anomaly detection.

Main Methods:

  • Deployment of near-infrared spectrometers on vehicle, airplane, and sUAS platforms for methane emission surveys.
  • Conducted surveys across 14 active, 4 inactive, and 4 abandoned coal mines in Kentucky from 2021-2022.
  • Compared field measurements with data from the EPA's Greenhouse Gas Reporting Program (GHGRP).

Main Results:

  • Vehicle-based surveys detected methane anomalies at 9 out of 13 active mines, with peak emissions of 665 ± 229 kg h⁻¹.
  • Airborne surveys identified anomalies at 3 sites, including a peak of 1062 ± 386 kg h⁻¹.
  • Vehicle-based estimates showed closer agreement with GHGRP values and lower uncertainties compared to airborne data.

Conclusions:

  • Vehicle-based methane emission monitoring is a viable and often superior alternative where terrain and road access permit.
  • Higher detection rates for vehicle-based surveys suggest enhanced capability in identifying methane anomalies.
  • Integrating multiple observational strategies is essential for comprehensive methane emission monitoring, particularly in data-scarce regions.
