Coastal marshes are vulnerable to erosion caused by rising seas, pounding waves, and tidal flows. In California's Elkhorn Slough, these vulnerabilities are made worse by superabundant crabs found at t...

The effects of increased nitrogen loading on denitrification and dissimilatory nitrate reduction to ammonium
(DNRA) in marsh sediments were studied in permanently submerged subtidal creek sediments a...

We examined the role of chronic low-level nutrient enrichment on the productivity of heterotrophic marsh
bacteria via a marsh fertilization experiment in which we mimicked the conditions of widesprea...

The inorganic content of 51 dated sediment cores from Mississippi River deltaic plain salt marsh wetlands peaks with the landfall of hurricanes. Variations in the inorganic sediment content demonstrat...
Prediction of velocity profiles and longitudinal dispersion in emergent salt marsh vegetation

To predict the behavior of solutes and suspended particles in wetlands, it is necessary to estimate advection and
longitudinal dispersion. To better understand these processes, measurements were take...

Using a multicomponent inverse model, we quantified the rates of organic matter (OM) remineralization and the relative importance of major terminal electron acceptors [Fe(III)-(oxy)hydroxides and SO4-...
Benthic metabolism and sulfur cycling along an inundation gradient in a tidal Spartina anglica salt marsh
