Data

This dataset contains a bare earth DEM, with a 0.5-square-meter (m2) cell size, of the Cottonwood Lake Study Area, Stutsman County, North Dakota. The digital elevation model (DEM) was based primarily on airborne lidar data acquired by Fugro Horizons of Rapid City, South Dakota., and made into a DEM by USGS personnel using the ArcGIS extension LP360 (QCoherent Software, 2013). Additional DEM proces

Spatial polygons of vegetation zones for wetlands within the Cottonwood Lake Study Area, Stutsman County, North Dakota. Created from a collection of digital orthorectified images from aerial photographs of the study area.

This dataset provides point locations of wetlands in the Cottonwood Lake Study Area to aid in identification of study area wetlands.

Collection of orthorectified images from aerial photograph of wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota. This collection of image were acquired during July and early August from 1975 to 2015. Aerial photographs of wetlands in the Cottonwood Lake Study Area were collected in order to facilitate a better understanding of the influence of natural climate variability o

The data set consists of data collected in 1995, 1996, and 1997 in wetlands in the Prairie Pothole Region of North Dakota and South Dakota. The data were summarized and used in the analysis for a U.S. Geological Survey Open File Report entitled: The influence of local- and landscape-level factors on wetland breeding birds in the Prairie Pothole Region of North and South Dakota. The data consist of

This dataset contains water chemistry measurements from groundwater wells at the Cottonwood Lake Study Area, Statesman County, North Dakota.

This dataset contains water chemistry information for wetlands at the Cottonwood Lake Study Area, Statesman County, North Dakota.

In situ specific conductance, pH, and temperature measurements from wells at the Cottonwood Lake Study Area, Statesman County, North Dakota, 1987 to 1995.

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 Cotto

This dataset contains water surface elevations for the wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota, 1979 through 2015.

This dataset contains the specific conductance values for all wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota, 1992 through 2015.

During 2013 and 2014 aquatic invertebrates were collected and vegetation was inventoried from sample locations distributed throughout Pool 10 and West Pool of Big Stone National Wildlife Refuge. Invertebrate sampling was conducted using aquatic activity traps and by collecting organisms from submersed vegetation. Vegetation was inventoried through a combination of visual observation and collection
