Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Data on the Deterioration of Different Types of Attachment Hardware on Sham Satellite Radio Collars Data on the Deterioration of Different Types of Attachment Hardware on Sham Satellite Radio Collars
Polar bears (Ursus maritimus) are difficult to study because of logistical challenges. Satellite radio collars are an excellent tool for efficiently collecting information on the distribution and habitat use of polar bears because they can be deployed for multiple years. Radio collars can be constructed using materials and devices that result in the collar falling off an animal so that...
The North American Breeding Bird Survey Mapping products 1966 - 2022 The North American Breeding Bird Survey Mapping products 1966 - 2022
This data product consists of raster digital data of population change and abundance estimates for 520 species of North American birds estimated from North American Breeding Bird Survey (BBS) data. Estimates of trend (yearly % change) from 1966-2022 and mean abundances for the interval 2018-2022 are spatially smoothed from data for each species collected on BBS routes. Metadata for the...

Tennessee groundwater well locations from 7.5-minute quadrangle maps Tennessee groundwater well locations from 7.5-minute quadrangle maps
The state of Tennessee is divided into 805 individual 7.5-minute topographic quadrangle maps. The Tennessee Department of Environment and Conservation (TDEC) maintains an archive of paper maps that were utilized for estimating groundwater well locations. Each well location was plotted by hand and marked with corresponding water well data. These hand-plotted locations represent the most...
Quantitative polymerase chain reaction and confocal microscopy data describing cell penetrating peptide-mediated delivery of gene silencing agents to the invasive common reed Phragmites australis Quantitative polymerase chain reaction and confocal microscopy data describing cell penetrating peptide-mediated delivery of gene silencing agents to the invasive common reed Phragmites australis
These data describe delivery of novel gene silencing agents (GSAs) to leaf tissue of the invasive common reed Phragmites australis ssp. australis using cell penetrating peptides (CPPs). These CPPs were tested for their ability to infiltrate P. australis leaf tissue using confocal microscopy. In addition, a series of novel gene silencing agents targeting a putative phytoene desaturase...
