This data set presents attributes of floodplain ecosystem characteristics including floodplain soil denitrification, floodplain soil biogeochemistry, floodplain vegetation, floodplain sedimentation, floodplain and channel morphometry, stream discharge and water quality, floodplain climate, floodplain physiographic region, and catchment land cover. Attributes are associated with 18 floodplains of the Chesapeake Bay watershed. For many of these attributes, mean values are summaries of multiple measurements made within each floodplain site.

Denitrification measurements and ecosystem attributes in hummock-hollow microtopography of tidal freshwater forested wetlands along longitudinal riverine positions (upper, middle, and lower tidal river sites, and nearby upstream nontidal forested floodplains) of the adjoining Pamunkey and Mattaponi Rivers, Virginia.

Geomorphometry for Streams and Floodplains in the Chesapeake and Delaware Watersheds was generated as part of the project Quantifying Floodplain Ecological Processes and Ecosystem Services in the Delaware River Watershed funded through the William Penn Foundation's Delaware Watershed Research fund. This dataset contains geomorphometry for streams and floodplains in the Chesapeake and Delaware River watersheds. Geomorphometry is a quantitative representation of landscape surface form (e.g., channel width and depth) obtained from digital elevation models (DEMs). The dataset contains geomorphometry derived from running 3-m DEMs through the Floodplain and Channel Evaluation Tool (FACET) version 0.1.0. FACET generates...
Measurements of the limitation of denitrification potential by oxygen and nitrate.
Categories: Data
Measurements of water level and porewater salinity at each site.

Soil physico-chemistry and phosphate release rated during laboratory flood experiment, for soils collected prior to restoration.
Categories: Data
Phosphate, ammonium, nitrate, and nitrate fluxes to and from the soil surface.
Categories: Data
Measurements of soil denitrification enzyme activity and moisture, bulk density, organic matter, total carbon, total nitrogen, potential carbon mineralization, extractable nitrate, and limitation of nitrification by aeration.

Datasets used to quantify and value the ecosystem service of sediment and nutrient retention for floodplains within the Difficult Run watershed located in Fairfax County, Virginia. Geospatial datasets include a digital elevation model (DEM), a hydrologically conditioned DEM, output from the USGS Stream Channel and Floodplain Metric Toolbox, and field data sets used to develop regression models to predict sediment and nutrient retention services for stream within the Difficult Run watershed.
Latitude and Longitude of study plots.

Chloropyron maritimum subsp. maritimum population counts at Sweetwater Marsh National Wildlife Refuge, California, and tide and weather data from San Diego, California, are used to explain interannual variation in Chloropyron counts and to predict past population counts.
