Data on denitrification and ecological characteristics of nontidal floodplains, Chesapeake Bay watershed, USA, 2013-2016
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.
Data on soil denitrification potential and physico-chemical characteristics of tidal freshwater forested wetlands in Virginia
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.
Measurements of the limitation of denitrification potential by oxygen and nitrate.
Measurements of water level and porewater salinity at each site.
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.
