Summary

Controlled degassing of Lakes Nyos and Monoun has reduced carbon dioxide (CO2) levels by 12-14%, increasing local stability. Further mitigation with more pipes is recommended to prevent future CO2 gas burst disasters.

Area of Science:

  • Geochemistry
  • Environmental Science
  • Limnology

Background:

  • Lakes Nyos and Monoun experienced catastrophic carbon dioxide (CO2) releases in the 1980s.
  • These lakes continue to experience high rates of CO2 recharge, posing a significant natural hazard.
  • Controlled degassing was implemented to mitigate disaster risk, despite concerns of destabilization.

Purpose of the Study:

  • To assess the impact of controlled degassing on lake stability and gas content.
  • To model future gas removal rates and predict the effectiveness of mitigation strategies.
  • To determine the optimal number of degassing pipes needed to reduce disaster risk.

Main Methods:

  • Analysis of limnological measurements over 12 years.
  • Monitoring of water column structure and gas saturation levels.

  • Development of a predictive model for gas removal rates and inventory.

    • Main Results:

    • Degassing has not compromised lake water column structure; local stability is increasing.
    • Gas content in the lakes has been reduced by approximately 12-14%.
    • Current single-pipe systems will only remove a fraction of remaining gas, necessitating additional pipes.

    Conclusions:

    • Controlled degassing is a viable mitigation strategy for CO2-rich lakes.
    • Multiple degassing pipes are required to substantially reduce the risk of future gas burst disasters.
    • Continued monitoring and intervention are crucial for long-term lake safety.
