Summary: Salt marshes play a crucial role in nutrient processing and are important for sensitive coastal environments. However, our understanding of the spatiotemporal variability of critical biogeochemical drivers in salt marshes is limited. This study highlights the importance of high-frequency in situ measurements, such as monitoring redox potential, in explaining the factors that govern subsurface biogeochemistry and hydrological processes in salt marshes.

Summary: Salt marshes can remove terrestrial nutrients before they reach the coast. However, our understanding of the variability of reactive solutes and processes within salt marshes is limited. In this study, we monitored nitrate concentrations in salt marsh porewater at Elkhorn Slough in California, USA, using a high-frequency sampling system. We found that tidal and seasonal hydrologic fluxes control nitrate dynamics and export in coastal environments.

Summary: Salt marshes are complex coastal systems where terrestrial groundwater, terrestrial surface water, and seawater mix. However, our understanding of water fluxes in these environments is limited due to the interactions between land and marine forcings. To improve our understanding, we used geochemical tracers and analytical models to investigate the water sources, flow directions, and velocities in salt marsh porewater. Our findings revealed seasonal recharge patterns and daily tidal cycles driving water dynamics in both deep and shallow subsurface environments. This understanding is crucial for studying biogeochemical cycles in salt marshes.

Summary: Reclaimed creeks showed significantly increased concentrations of dissolved carbon and nitrogen species, with slightly decreased N2O and NO3--N. They also exhibited higher global warming potential, making them hotspots for greenhouse gas effects compared to natural tidal creeks.

Summary: The study found that mangroves do not reduce the ability of salt marshes to adapt to sea level rise, and activities that limit mangrove encroachment into salt marshes will not improve the salt marshes' sediment trapping capacity.

Summary: This study quantified the net flux of dissolved organic carbon (DOC) through the main creek channel of a salt marsh in Georgia, USA. Results showed periods of non-conservative behavior, indicating significant DOC outwelling during the productive summer months.

Summary: This study used a 3D fully coupled modeling system to simulate the final vegetation cover and timescale of salt marshes under different forcing conditions. The simulations showed that sediment concentration, settling velocity, sea level rise, and tidal range each had different impacts on the equilibrium coverage and timescale of marshes.

Summary: Salt marshes play a key role in attenuating wave energy and promoting sedimentation necessary to potentially adapt to sea level rise. The soil surface elevation in the marsh region varies spatially and temporally as a function of marsh topography, inundation frequency, and distance to the salt marsh edge. The sedimentation rate reduces linearly shoreward and is highest around the mean high-water level, moving towards the edge of the salt marsh with marsh extension and increasing soil surface elevation.

Summary: This study examines the wave attenuation over combinations of different vegetation types on tidal flats. The results show that the impact of vegetation combinations lies between that of individual vegetation types. The study proposes an empirical formula for calculating the wave transmission coefficient, taking into account multiple vegetation characteristics.

Summary: This study investigates the influence of Triglochin concinna on the salt marsh plain plant assemblage in terms of nitrogen dynamics. The results show that Triglochin can accumulate nitrogen in its roots and shoots, release nitrogen to neighbors as its litter decomposes, and reduce the biomass of surrounding plants. This suggests that Triglochin can play a role in the restoration of salt marsh vegetation.

Summary: Coastal protection provided by tidal wetland vegetation is crucial in defending coastlines against storm surges. This study examines how extreme wave events affect salt-marsh vegetation and whether plant properties influence plant resistance. The results reveal that salt-marsh vegetation is more robust than expected, with pioneer species showing higher resistance. The height of the vegetation canopy and the stiffness of stems also play a role in defining plant resistance.

Summary: This study proposes an alternative methodology to identify priority areas for conservation using a combination of LANDSAT satellite remote sensing and numerical modelling. It identifies the most deteriorated salt marshes in central and upper lagoon regions and determines that marsh loss and degradation are primarily due to increased tidal action triggered by deepening lagoon channels. The study predicts that climate-induced mean sea level rise will exacerbate marsh deterioration, emphasizing the importance of protecting and restoring salt marshes.

Summary: Salt marshes are important ecosystems that are being threatened by sea level rise and human activities. This study analyzed changes in vegetated marsh areas over 70 years at three LTER sites on the US East Coast, showing different patterns of change at each site. Factors affecting marsh dynamics are complex and vary in their impact on vegetation loss and gain.

Summary: As salt marshes migrate upland due to rising sea levels, they face challenges in the form of hazardous and contaminated sites (HCSs) that can release toxins if compromised. This study in Rhode Island, USA, inventoried HCSs and found that they are extensive along marsh migration corridors, especially in urban areas. This inventory provides important information for prioritizing and managing salt marshes in the face of accelerated sea level rise.
