Spatial models indicating avian influenza transmission risk at the interface of domestic poultry and wild birds in China Spatial models indicating avian influenza transmission risk at the interface of domestic poultry and wild birds in China
Emergence of avian influenza viruses with high lethality to humans, such as the currently circulating highly pathogenic A(H5N1) and A(H7N9) cause serious concern for the global economic and public health sectors. To improve our understanding of the spatial and temporal trends in transmission risk we developed a model that predicts hotspots of novel virus emergence between domestic and...
Data measuring avian influenza infection, mercury concentration, and body condition in wild waterfowl Data measuring avian influenza infection, mercury concentration, and body condition in wild waterfowl
These data represent mercury contamination, influenza infection, and body condition in 11 species of dabbling and diving ducks in the Pacific Flyway. These data support a USGS lead scientific publication.
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...
