Sea level rise increases the frequency and intensity of storm surges extreme tidal events in coastal freshwater wetlands. Seawater affects soil biogeochemical processes by inducing osmotic stress stimulating SO42− reduction. The objective this study was to determine mechanism which salinity alters C mineralization rates quantifying relative importance ionic stress, compared with addition electron acceptor, on production CO2 CH4. A batch incubation measured potential anaerobic respiration...
Coastal wetlands are susceptible to loss in both health and extent via stressors associated with global climate change anthropogenic disturbance. Peat collapse may represent an additional phenomenon contributing coastal wetland organic-rich soils through rapid vertical elevation decline. However, the term "peat collapse" has been inconsistently used literature, leading ambiguities regarding mechanisms, timing, spatial of its contribution loss. For example, it is unclear whether peat distinct...
As atmospheric carbon (C) concentrations increase, so too has interest in understanding the mechanisms that preserve C within soil organic matter (SOM). Mineral-associated (MAOM) is one pool of SOM recently shown to protect from mineralization. However, most MAOM research been agriculture and forest mineral soils. Given magnitude stored wetlands, this study sought determine abundance wetlands. A standard method for quantifying terrestrial soils was tested, modified, optimized with three...
Abstract Rates of organic carbon (OC) burial in some coastal wetlands appear to be greater recent years than they were the past. Possible explanations include ongoing mineralization older OC or influence an unaccounted‐for artifact methods used measure rates. Alternatively, trend may represent real acceleration burial. We quantified rates mangrove and freshwater marshes southwest Florida through a comparison derived from 210 Pb, 137 Cs, surface marker horizons. Age/depth profiles lignin:...
Core Ideas Fresh water pulse to salt marsh soil reduced denitrification. Salt denitrification by 73% in fresh soil. Coastal storm surges can dramatically reduce River flood pulses The coastal wetlands of southern Louisiana provide an ideal environment for removing nitrate (NO3−) from the Mississippi before discharge into Gulf Mexico where it contribute hypoxia. However, denitrification, primary mechanism excess N removal, may be sensitive fluctuating salinities that characterize wetlands....

<title>Abstract</title> Tidal wetlands are hotspots of soil accumulation due to high sedimentation rates and low oxygen concentrations that inhibit organic matter decomposition1. Accordingly, tidal can sequester “blue carbon” at much higher than other ecosystems2,3 helping offset human emissions. Organic carbon burial is tightly linked the cycling nitrogen, which a key pollutant limiting nutrient for many ecosystems4–6. Yet, current global rate nitrogen” how it may respond future change...
Core Ideas Ammonium that accumulated in the porewater following an influx of seawater took ∼1 wk to flux into surrounding water. Soluble reactive P concentrations both and water increased with salinity. Nutrient export was influenced by wetland soil type. Saltwater intrusion could catalyze rapid nutrients from freshwater soils coastal zone, especially organic matter‐rich soils. Coastal wetlands are vulnerable saltwater intrusion, which may alter biogeochemical processes, lead contribute...
The use of loss on ignition (LOI) measurements soil organic matter (SOM) to estimate carbon (OC) content is a decades-old practice. While there are limitations and uncertainties this approach, it continues be necessary for many coastal wetlands researchers conservation practitioners without access an elemental analyzer. Multiple measurement, reporting, verification (MRV) standards recognize the need (and uncertainty) using method. However, no framework exists explain substantial differences...
Oyster reef restoration efforts increasingly consider not only oyster recruitment, but also the recovery of ecological functions and prevention deploying harmful plastics. This study investigated efficacy a biodegradable plastic-alternative, BESE-elements®, in supporting east-central Florida (USA) with consideration for how this material influences biogeochemistry. Four experiments (two laboratory, two field-based) were conducted to evaluate ability BESE serve as microbial substrate, release...
