Data on diurnal variation in wetland methane flux were collected to 1) improve understanding of short-term, mechanistic drivers of methane flux, and 2) inform sampling protocols to achieve research objectives. An automated gas flux sampling system was used to measure methane flux every 2.5–4 hours for over 230 diel cycles over the course of three growing seasons (2013–2015). Data were collected from a seasonal, depressional wetland located in the Prairie Pothole Region of central North America. These data directly support the associated publication “Diurnal patterns of methane flux from a depressional, seasonal wetland: mechanisms and methodology” which is referenced within the Metadata.

This data release presents data that were collected as part of a larger effort to assess the carbon balance of recently exposed (i.e., no vegetation cover) wetland sediments. This work was part of an international collaborative effort associated with the Dryflux II project. During June and July 2021, data were collected from three artificial ponds located near Jamestown, North Dakota, to estimate carbon dioxide flux, vegetation characteristics, and soil properties. Numerous covariates related to atmospheric and soil conditions also were measured. Water levels of the artificial ponds, which are managed by the U.S. Geological Survey Northern Prairie Wildlife Research Center, were manipulated to mimic the natural drying...

A study was conducted to assess the relationships among carbon mineralization, sulfate reduction and greenhouse gas emissions in prairie pothole wetlands. These data are for dissolved methane and carbon dioxide concentrations and fluxes. Dissolved gas concentrations in the water column and fluxes to the atmosphere were estimated from April through November, 2015 for wetlands P7 and P8 of the Cottonwood Lake Study area, Stutsman County, North Dakota. Dissolved gases in the water column were collected every two weeks using a pumping-induced ebullition device. Gas flux samples were collected concurrently at the water-atmosphere interface using the vented static-chamber method. Gas concentrations of the gas samples...

This data release encompass numerous studies examining soil properties and greenhouse gas fluxes of Prairie Pothole Region (PPR) wetland catchments. The PPR is one of the largest wetland ecosystems in the world, encompassing approximately 770,000 square kilometers of the north-central U.S. and south-central Canada, with the U.S. portion including parts of Iowa, Minnesota, South Dakota, North Dakota, and Montana. The data included in this release span a 19-year period (1997–2016) and represent a diversity of studies ranging from localized (e.g., wetland catchments and complexes) to region-wide efforts that span the PPR’s climate and land-use gradient. Data from individual wetland catchments encompass a variety of...

This data release presents data from a laboratory microcosm study examining the potential effects of herbicide application on the production and flux of greenhouse gases from wetland soils. Wetland soils were placed into glass mason jars and covered with water. Microcosms were treated with varying concentrations (none, low, medium, high) and combinations of the herbicides glyphosate and 2,4-D. Following herbicide application greenhouse gas fluxes were measured and concentrations of dissolved greenhouse gases were determined periodically over a 21-day period.
This data release presents input data for plot- and landscape-scale models of Prairie Pothole Region wetland methane emissions as a function of explanatory variables and remotely sensed predictors. Field data for the plot- and landscape-scale models span the years 2003-2016 and 2005-2016, respectively. The data release also includes R programming code to run the generalized additive model (GAM; plot scale) and random forest (RF; landscape scale) model of methane flux rates. Input data were extracted and modified from existing sources, and combined to facilitate model development, as well as six scenario-based model runs (two historical, four future). Briefly, a bottom-up approach was used to develop a spatially...
