    Methane bubbles are common in muddy organic-rich marine sediments. It has been speculated that pressure variations, due to tides, play a significant role both in their growth and release. In fact, observations show that ...
  • The effect of resuspension on chemical exchanges at the sediment-water interface in the deep sea - A modelling and natural radiotracer approach

    Bioturbation in aquatic sediments results from many different biological activities, inducing particle displacement over a variety of length and time scales. Despite this inherent complexity, empirical tracer studies show ...
  • Bioturbation and porosity gradients 

    Mulsow, S., BP Boudreau, and JN Smith. 1998. "Bioturbation and porosity gradients." Limnology and Oceanography 43(1): 1-9.
    Ubiquitous porosity gradients have a potentially important effect on the mixing of particle-bound tracers, such as Pb-210. Mass-depth coordinates cannot be used to deal with these effects if values of the traditional mixing ...

    The intensity of biogenic sediment mixing is often expressed as a "biodiffusion coefficient" (D (sub b) ), quantified by fitting a diffusive model of bioturbation to vertical profiles of particle-bound radioisotopes. The ...
