  • Initial rise of bubbles in cohesive sediments by a process of viscoelastic fracture 

    Algar, Christopher K.; Boudreau, Bernard P.; Barry, Mark A. (American Geophysical Union, 2011-04-14)
    An understanding of the mechanics of bubble rise in sediments is essential because of the role of bubbles in releasing methane to the atmosphere and the formation and melting of gas hydrates. Past models to describe and ...
  • Predicting microbial nitrate reduction pathways in coastal sediments 

    Algar, Christopher K.; Vallino, Joseph J. (Inter-Research, 2014-01-23)
    We present an ecosystem model that describes the biogeochemistry of a sediment nitrate reducing microbial community. In the model, the microbial community is represented as a distributed metabolic network. Biogeochemical ...
  • Release of multiple bubbles from cohesive sediments 

    Algar, Christopher K.; Boudreau, Bernard P.; Barry, Mark A. (American Geophysical Union, 2011-04-20)
    Methane is a strong greenhouse gas, and marine and wetland sediments constitute significant sources to the atmosphere. This flux is dominated by the release of bubbles, and quantitative prediction of this bubble flux has ...
