This release consists of vegetation data collected across an environmental gradient at Ten Thousand Islands National Wildlife Refuge (TTI NWR) near Naples, Florida, USA. The refuge is within the impact area of the Picayune Strand Restoration Project (PSRP), a large-scale hydrologic restoration project in southwest Florida that was authorized by the U.S. Congress in 2007. Vegetation transects were located in the following wetland types on the refuge: brackish marsh, salt marsh, and transition marsh. Data from vegetation transects established in nearby areas outside of the PSRP impact area, in Fakahatchee Strand Preserve State Park (FSPSP) and Big Cypress National Preserve (BICY), are also included. The study spanned...
Extended time-series sensor data were collected between 2012 and 2016 in surface water of a tidal salt-marsh creek on Cape Cod, Massachusetts. The objective of this field study was to measure water chemical characteristics and flows, as part of a study to quantify lateral fluxes of dissolved carbon species between the salt marsh and estuary. Data consist of in-situ measurements including: salinity, temperature, pH, dissolved oxygen, redox potential, fluorescent dissolved organic matter, turbidity and chlorophyll. Surface water flow, water level and water elevation data were also measured. The data provided in this release represent a compiled data set consisting of multiple sensor deployments between 2012 and 2016.

Vertical accretion and elevation change of marshes is a critical factor controlling marsh survival and adaptability to rising sea levels. A wide variety of existing methods have been employed to measure accretion and elevation change in marshes on time scales ranging from weeks to centuries on many individual marshes located throughout the coastal northeastern United States. This dataset is a compilation of marsh accretion and elevation change rates compiled from a total of 27 published studies and 3 data sets published from 1975 through 2021, yielding a total of 292 individual estimates of marsh accretion or elevation change. The database includes: measurements of marsh surface elevation change from repeat surveys...

Wind speed, wind direction (3D) and gas concentrations are measured at 10 Hz and statistically processed using the eddy covariance technique to half-hour estimates of flux rates of gas exchange between the ecosystem and atmosphere. Three gases were measured: carbon dioxide, methane and water vapor. Simultaneous measurements of environmental drivers are also measured and recorded as half-hourly values: photosynthetic photon flux density, downwelling and upwelling short and long wave radiation, air temperature, relative humidity and precipitation. Variable names and units follow AmeriFlux and FLUXNET standards. This site is a saltwater herbaceous marsh near Lake Hermitage, LA and Barataria Bay.
A critical factor controlling marsh survival and adaptability to rising sea level is an adequate supply of sediment for supporting upward growth of marshes, yet sediment availability and the factors that control its delivery to marshes remain poorly constrained. This dataset includes the results of sediment trap deployments and accompanying water level recordings from 9 coastal salt marshes in the northeastern United States. Sediment traps were deployed seasonally, with individual spring, summer, and fall deployment periods over the course of 2020-2021. The distribution of study sites spans differences in tidal range, wave climate, sea surface temperature, and assemblages of marine organisms. Additionally, these...
