Earth’s critical zone sustains surficial life (humans included) and accounts for most water, carbon, and other
bio/geochemical cycling. Although mass and energy transport are generally understood according to
physical and chemical laws, in the critical zone biology gets in the way: literally. The partitioning of
available water, carbon, solutes, and energy between biological and geological reservoirs is a fundamental
function of the critical zone and yet one that is incompletely understood. This seminar presents the setting of
intertidal wetlands as a model system for studying this complex partitioning. Specifically, the seminar will
describe new insights gained from the salt marsh model system regarding the relative roles of terrestrial
vegetation and dynamic physical processes in driving surface-atmosphere and surface-subsurface water,
energy, carbon, and solute exchange. The seminar will conclude with a discussion of promising
opportunities for better understanding the coupled and parallel roles of biological and hydrogeological mass
and energy transport and storage in the critical zone.
