Brine Contamination to Plains and Potholes Environments from Energy Development in the Williston Basin
Restoring Montana Pothole Wetlands - Demonstration Sites and Adaptive Management
Geologic processes from the last ice age have generated extensive areas of pothole wetlands in several Montana landscapes. The Laurentide ice sheet, originating in the Northwest Territories, provided the dominant force in eastern Montana. Similar landscapes developed in the broad valleys of western Montana through the actions of the Cordilleran ice sheet, originating in the mountains of British...
Birds and the Bakken: Integration of oil well, land cover, and species distribution data to inform conservation in areas of energy development
The goal of this project was to develop a novel methodology to combine the USGS Gap Analysis Program (GAP) national land cover and species distribution data with disturbance data to describe and predict how disturbance affects biodiversity. Specifically, the project team presented a case study examining how energy development in the Williston Basin can affect grassland birds; however, the methods
NOROCK's Small Unmanned Aircraft Systems (sUAS) Program
Scientists at NOROCK are actively exploring the use of small unmanned aerial system (sUAS) for sensor testing and scientific data collection. We are using the same sUAS deployed by the US Department of Defense. These systems have proven their utility in reconnaissance missions and are now finding a second life in scientific research.
Summarization of National NEXRAD Data for use in Biological Applications
The U.S. network of 160 weather radars known as NEXRAD (NEXt generation RADar) is one of the largest and most comprehensive terrestrial sensor networks in the world. To date, the National Climatic Data Center (NCDC) has archived about 2 petabytes data from this system. Although designed for meteorological applications, these radars readily detect the movements of birds, bats, and insects. Many
Erosion rates and salinity and selenium yields in a basin near Rangely, Colorado following the 2017 Dead Dog wildfire as modeled by WEPP and measured from UAV
This data release accompanies a U.S Geological Survey study that assessed sediment, salinity, and selenium yields following the Dead Dog wildfire in northwestern Colorado. The Dead Dog fire ignited on June 11, 2017, near Rangely, Colorado, and burned over 17,000 acres, including the B2 study area. Two methodologies were used to quantify erosion and associated salinity and sediment yields in the B2

Fractional cover estimates of sweet clover derived from UAV, aerial, and Sentinel-2 imagery for central Montana and northwest South Dakota, 2019
Yellow sweet clover (Melilotus officinalis; clover hereafter) is a biennial legume native to Eurasia that is now present in all 50 states. Clover can grow 2 m tall and achieve high densities across large areas in the Northern Great Plains when conditions are conducive, such as in 2019. Clover is highly efficient at fixing nitrogen in soils which reduces the abundance of native grasses, while simul

Orthoimagery, digital elevation, digital terrain, final surface, and vegetation classification models for four stream catchments in western Colorado 2016
Unmanned Aerial System (UAS) flights were conducted over four stream catchments in Rio Blanco County, Colorado, during the summer of 2016. Two sties had active oil and gas operations within the basin whereas the other two sites did not. Structure from motion (SfM) was used to align raw images and create a dense point cloud, georectified orthoimage, and Digital Elevation Model (DEM) for each basin.

Potential effects of energy development on environmental resources of the Williston Basin in Montana, North Dakota, and South Dakota—Water resources
The Williston Basin has been a leading oil and gas producing area for more than 50 years. While oil production initially peaked within the Williston Basin in the mid-1980s, production rapidly increased in the mid-2000s, largely because of improved horizontal (directional) drilling and hydraulic fracturing methods. In 2012, energy development associated with the Bakken Formation was identified as a

Effects of energy development on wetland plants and macroinvertebrate communities in Prairie Pothole Region wetlands
Energy production in the Williston Basin, USA, results in the coproduction of highly saline, sodium chloride-dominated water (brine).
