grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases, version 1.1.0 grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases, version 1.1.0
Greater sage-grouse (Centrocercus urophasianus) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the western United States. They occupy the sagebrush biome in western North America, extending east of the Sierra Nevada/Cascade Mountain ranges to the western regions of the Great Plains of the United States. Sage-grouse are one of the most...
Estimated crop irrigation water use withdrawals in Hualapai Valley Groundwater Basin, Arizona for 2021 Estimated crop irrigation water use withdrawals in Hualapai Valley Groundwater Basin, Arizona for 2021
Observations of irrigated agricultural land within the Hualapai Valley Groundwater Basin in Arizona. Crops were verified in situ once in 2021 on May 20th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program images dated 2021 and supplemented with Landsat and Sentinel2 imagery collections accessed...
Concentrations and laboratory quality-assurance data for six unregulated contaminants measured in source and finished drinking-water samples collected from public water systems throughout Minnesota by using ELISA and MS-based analytical methods Concentrations and laboratory quality-assurance data for six unregulated contaminants measured in source and finished drinking-water samples collected from public water systems throughout Minnesota by using ELISA and MS-based analytical methods
The U.S. Geological Survey, in cooperation with the Minnesota Department of Health, conducted a study to determine the occurrence of six unregulated contaminants in source and finished drinking-water samples collected from 67 public water supply systems throughout Minnesota. Minnesota relies on groundwater and surface water sources for drinking water. Land use, such as wastewater...
Mainstem Rivers of the Conterminous United States Mainstem Rivers of the Conterminous United States
Mainstem rivers are the backbone of a connected network of hydrologic units that cover the landscape. A mainstem connects a headwater source area to an outlet. This data release identifies the same mainstem paths in hydrographic datasets for the conterminous US. The Mainstems dataset includes cross walks between mainstem identifiers and several hydrographic datasets. These cross walk...
Passive flux meter data from monitoring wells and sentinel wells in relation to the Kirtland Air Force Base Bulk Fuels Facility, Albuquerque, New Mexico Passive flux meter data from monitoring wells and sentinel wells in relation to the Kirtland Air Force Base Bulk Fuels Facility, Albuquerque, New Mexico
This U.S. Geological Survey (USGS) data release contains push-pull test results, Darcy velocity data, and contaminant mass flux data measured in Albuquerque, New Mexico, using passive flux meters (PFMs) in monitoring and sentinel wells associated with the Kirtland Air Force Base (KAFB) Bulk Fuels Facility. Push-pull test results were used to correct Darcy velocity data collected at large...
Wolf noninvasive methods trial from 2019-2021 in the Superior National Forest metadata Wolf noninvasive methods trial from 2019-2021 in the Superior National Forest metadata
This dataset contains gray wolf (Canis lupus) study area section counts of pack wolves by method (observing radiocollared wolves and their packmates via aerial telemetry and also noninvasive methods including ground snow tracking, aerial snow tracking, camera trapping, community scientist reports) from a three winter noninvasive methods trial during 2019-2021 in the USGS Wolf Project...
