They represent complex multiphase environments, with structural and geochemical heterogeneities expressed over spatial scales ranging from the molecular to field scale. In situ rates at which resident microbial populations produce and consume chemical constituents are

In such settings, solutes move preferentially (by advection) through macropores and slowly (by diffusion) into intra-aggregate micropores, which promotes the establishment of redox gradients at the aggregate scale.
