Over, Under, and Through: Hydrologic Connectivity and the Future of Coastal Landscape Salinization Open
Seawater intrusion (SWI) affects coastal landscapes worldwide. Here we describe the hydrologic pathways through which SWI occurs ‐ over land via storm surge or tidal flooding, under land via groundwater transport, and through watersheds vi…

Blue nitrogen follows the fate of tidal wetlands Open
Tidal wetlands are hotspots of soil accumulation due to high sedimentation rates and low soil oxygen concentrations that inhibit organic matter decomposition1. Accordingly, tidal wetlands can sequester “blue carbon” at much higher rates th…

Methane fluxes in tidal marshes of the conterminous United States Open
Methane (CH 4 ) is a potent greenhouse gas (GHG) with atmospheric concentrations that have nearly tripled since pre‐industrial times. Wetlands account for a large share of global CH 4 emissions, yet the magnitude and factors controlling CH…

Metal accumulation in salt marsh soils along the East Coast of the United States Open
Coastal salt marshes are depositional environments that can accumulate pollutants introduced to the environment from human activities. Metals are a contaminant of concern in coastal environments due to their longevity and toxicity. We asse…

Practical Guide to Measuring Wetland Carbon Pools and Fluxes Open
Wetlands cover a small portion of the world, but have disproportionate influence on global carbon (C) sequestration, carbon dioxide and methane emissions, and aquatic C fluxes. However, the underlying biogeochemical processes that affect w…

Recent Acceleration of Wetland Accretion and Carbon Accumulation Along the U.S. East Coast Open
The long‐term stability of coastal wetlands is determined by interactions among sea level, plant primary production, sediment supply, and wetland vertical accretion. Human activities in watersheds have significantly altered sediment delive…

Cooperative microbial interactions mediate community biogeochemical responses to saltwater intrusion in wetland soils Open
In freshwater wetlands, competitive and cooperative interactions between respiratory, fermentative and methanogenic microbes mediate the decomposition of organic matter. These interactions may be disrupted by saltwater intrusion disturbanc…

The Invisible Flood: The Chemistry, Ecology, and Social Implications of Coastal Saltwater Intrusion Open
Saltwater intrusion is the leading edge of sea-level rise, preceding tidal inundation, but leaving its salty signature far inland. With climate change, saltwater is shifting landward into regions that previously have not experienced or ada…

A simple and effective sampler to collect undisturbed cores from tidal marshes Open
Core sampling is a common procedure in wetland ecology. PVC tubes are widely used to collect soil cores; however several studies fail to describe even the most typical characteristics of their sampling auger. This work aims to fill this ga…

Biophysical drivers of carbon dioxide and methane fluxes in a restored tidal freshwater wetland Open
Wetlands store large amounts of carbon (C) in biomass and soils, playing a crucial role in offsetting greenhouse gas (GHG) emissions; however, they also account for 30% of global yearly CH4 emissions. Anthropogenic disturbance has led to t…

Contributions of organic and inorganic matter to sediment volume and accretion in tidal wetlands at steady state Open
A mixing model derived from first principles describes the bulk density ( BD ) of intertidal wetland sediments as a function of loss on ignition ( LOI ). The model assumes that the bulk volume of sediment equates to the sum of self‐packing…
