Elevated CO2 enhances biological contributions to elevation change in coastal wetlands by offsetting stressors associated with sea-level rise. How does vegetation affect sedimentation on tidal marshes? Investigating particle capture and hydrodynamic controls on biologically mediates sedimentation. Quantifying saltmarsh vegetation and its effect on wave height dissipation: Results from a UK east coast saltmarsh. Impact of vegetation die-off on spatial flow patterns over a tidal marsh. Temmerman, S., Moonen, P., Schoelynck, J., Govers, G. Tidal landforms, patterns of halophytic vegetation and the fate of the lagoon of Venice. Feedbacks between inundation, root production, and shoot growth in a rapidly submerging brackish marsh. This article proposes that an optimum elevation (flooding frequency) for plant growth defines the transition from stable to unstable marsh. Responses of coastal wetlands to rising sea level. Caribbean mangroves adjust to rising sea level through biotic controls on change in soil elevation. Short-term (≤ 2 yrs) estuarine mudflat and saltmarsh sedimentation: High-resolution data from ultrasonic altimetry, rod surface-elevation table, and filter traps. Spatial and temporal factors controlling short-term sedimentation in a salt and freshwater tidal marsh, Scheldt Estuary, Belgium, SW Netherlands. The response of coastal marshes to sea-level rise: survival or submergence? Earth Surf. Vegetation engineers marsh morphology through multiple competing stable states. How vegetation and sediment transport feedbacks drive landscape change in the Everglades and wetlands worldwide. Holocene sea level database for the Atlantic coast of the United States. Climate related sea-level variations over the past two millennia. Episodic growth of Holocene tidal marshes in the northeastern United States: a possible indicator of eustatic sea-level fluctuations.
This provides a summary of elevation trends and the factors that control them from marshes around the world. in Wetlands and Natural Resource Management: Ecological Studies, Vol. Tidal marsh sedimentation and resilience to environmental change: exploratory modeling of tidal, sea-level, and sediment supply forcing in predominantly allochthonous systems. Numerical models of salt marsh evolution: ecological, geomorphic, and climatic factors. This article demonstrates that the maximum rate of sea-level rise a marsh can survive is a linear function of sediment supply and tidal range.įagherazzi, S. Limits on the adaptability of coastal marshes to rising sea level. Forecasting the effects of accelerated sea-level rise on tidal marsh ecosystem services. A blueprint for blue carbon: towards an improved understanding of the role of vegetated coastal habitats in sequestering CO2. This article estimates that half of global wetlands have been lost due to direct human conversion. Estimating global “blue carbon” emissions from conversion and degradation of vegetated coastal ecosystems. Marshland conversion to cropland in northeast China from 1950 to 2000 reduced the greenhouse effect.
