A study was conducted during 2004 to examine soil carbon storage of Prairie Pothole Region wetland catchments. These data represent the soil profile descriptions performed during that study; the remaining data were published previously (https://doi.org/10.5066/F7KS6QG2). Soil profile descriptions were performed at 270 temporary, seasonal, and semipermanent wetland catchments distributed throughout the Glaciated Plains and Missouri Coteau physiographic regions of the Prairie Pothole Region. Data were collected from four to six wetland and upland zones of the catchment. Study sites included cropland, restored grassland (formerly cropland), and native prairie (no cultivation history) catchments located in Iowa, Minnesota, Montana, North Dakota, and South Dakota.

This data release supports the manuscript entitled "Multiple approaches to surface water quality assessment provide insight for small streams experiencing oil and natural gas development" (DOI )and includes two data sets: 1) Mean daily discharge, temperature, and conductivity data from three stream sites in the Wyoming Range for summers 2012-2016; 2) Suspended sediment and macroinvertebrate metrics for 40 stream sites in the Wyoming Range for August 2016.

Aquatic features critical to watershed hydrology range widely in size from narrow, shallow streams to large, deep lakes. In this study we evaluated wetland, lake, and river systems across the Prairie Pothole Region to explore where pan-sharpened high-resolution (PSHR) imagery, relative to Landsat imagery, could provide additional data on surface water distribution and movement, missed by Landsat. We used the monthly Global Surface Water (GSW) Landsat product as well as surface water derived from Landsat imagery using a matched filtering algorithm (MF Landsat) to help consider how including partially inundated Landsat pixels as water influenced our findings. The PSHR outputs (and MF Landsat) were able to identify ~60-90% more surface water interactions between waterbodies, relative to the GSW Landsat product. However, regardless of Landsat source, by documenting many smaller (<0.2 ha), inundated wetlands, the PSHR outputs modified our interpretation of wetland size distribution across the Prairie Pothole Region.

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 wetland classes ranging from small, ephemerally-ponded wetlands to large, shallow lakes. Although study designs and methodologies differ slightly among the studies, the overarching methods are comparable and allow the data to be combined into a single data release. The data release consists of combined datasets (i.e., all studies) for soils, greenhouse gases, topography, water chemistry, weather, and covariate or explanatory variables such as water depth, soil moisture, and temperature. A majority of the studies also present data from the entire wetland catchment, with data collected from numerous landscape positions along transects spanning from the wetland center to the catchment boundary. Sample frequency among the studies ranges from a single site visit per year, to season-long, biweekly sample events across multiple years.
