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.

The North American Breeding Bird Survey, Analysis Results 1966 - 2022 The North American Breeding Bird Survey, Analysis Results 1966 - 2022
This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 548 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross
R Code Supporting the Manuscript: Using Stochastic Point Pattern Analysis to Track Regional Orientations of Magmatism During the Transition to Cenozoic Extension and Rio Grande Rifting, Southern Rocky Mountains R Code Supporting the Manuscript: Using Stochastic Point Pattern Analysis to Track Regional Orientations of Magmatism During the Transition to Cenozoic Extension and Rio Grande Rifting, Southern Rocky Mountains
This repository contains code that supports ongoing research in the southern Rocky Mountains in Colorado and northern New Mexico. This region hosted intracontinental magmatism that developed during a tectonic transition from shortening (Laramide orogeny, ca. 75 to 40 Ma) through extension and rifting. The code in this repository presents a novel approach that uses stochastic weighted...
SAS: Software Application for SMASH (Spectral Mixture Analysis for Surveillance of Harmful Algal Blooms) SAS: Software Application for SMASH (Spectral Mixture Analysis for Surveillance of Harmful Algal Blooms)
The Software Application for SMASH (Spectral Mixture Analysis for Surveillance of Harmful Algal Blooms), or SAS for short, is an application to facilitate mapping of potentially harmful algal blooms in reservoirs, rivers, and lakes from remotely sensed data. More specifically, SAS is designed to exploit the detailed observations of reflectance available within a hyperspectral image to...
Airborne magnetic and radiometric survey, western Arkansas, 2022 Airborne magnetic and radiometric survey, western Arkansas, 2022
This publication provides digital flight line data for a high-resolution magnetic and radiometric survey over part of western Arkansas. The airborne geophysical survey was funded by the USGS National Cooperative Geologic Mapping Program. The survey covers a rectangular area 91.55 by 92.15 kilometers (km) over the transition between the Ouachita Mountains and Ozark Plateau physiographic...
Mofete and San Vito geothermal field ore mineralization data Mofete and San Vito geothermal field ore mineralization data
The Mofete and San Vito geothermal fields, located west of Naples, Italy, are part of the Campi Flegrei volcanic complex. A joint venture in the 1970s between AGIP and ENEL, the Italian National electric and petroleum utilities, respectively, drilled exploratory wells to a depth of ~3000 m in an attempt to locate high-enthalpy fluids for potential power production. Drill core samples...
Data for Machine Learning Predictions of Nitrate in Shallow Groundwater in the Conterminous United States Data for Machine Learning Predictions of Nitrate in Shallow Groundwater in the Conterminous United States
An extreme gradient boosting (XGB) machine learning model was developed to predict the distribution of nitrate in shallow groundwater across the conterminous United States (CONUS). Nitrate was predicted at a 1-square-kilometer (km) resolution at a depth below the water table of 10 m. The model builds off a previous XGB machine learning model developed to predict nitrate at domestic and...
Urban Waters Federal Partnership: Novel bacteria monitoring technology in support of recreational water quality monitoring in the Lower Delaware River Urban Waters Federal Partnership: Novel bacteria monitoring technology in support of recreational water quality monitoring in the Lower Delaware River
The United States Geological Survey’s (USGS) New Jersey Water Science Center, in coordination with the Delaware River Basin Commission (DRBC) deployed a novel bacterial water-quality monitor, the Fluidion Alert V2 (Fluidion), in the Delaware River at Pyne Poynt Park in Camden County, New Jersey. Following United States Environmental Protection Agency (EPA) recreational water quality...
HOPS: Hyperparameter optimization and predictor selection HOPS: Hyperparameter optimization and predictor selection
We developed the hyperparameter optimization and predictor selection (HOPS) software to optimize hyperparameters and predictor selection while limiting correlation among the selected predictors for machine learning models. Including correlated predictors in machine learning models can distort model estimation and prediction and introduce bias in predictor importance estimates. The HOPS...
Peak-Flow Frequency Analysis for 464 U.S. Geological Survey Streamgages in Illinois, Indiana, and Wisconsin, Based on Data Through Water Year 2017 Peak-Flow Frequency Analysis for 464 U.S. Geological Survey Streamgages in Illinois, Indiana, and Wisconsin, Based on Data Through Water Year 2017
The U.S. Geological Survey (USGS) Central Midwest Water Science Center (CMWSC) completed a report (Over and others, 2023) documenting methods for peak-flow frequency analysis in Illinois following Bulletin 17C guidelines. The methods are used to provide estimates of peak-flow quantiles for 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for...
Channel incision characteristics in Clarksburg, MD Channel incision characteristics in Clarksburg, MD
This dataset describes field-measured qualitative stream channel characteristics indicative of incision and remotely-measured predictions of channel incision from lidar in three headwater streams in the Piedmont physiographic region of Maryland. The files within the field-measured channel incision folder include 1) a point file of original survey locations with a description of channel
Gene Transcription and Heat Shock Protein 70 Abundance in Juvenile Hatchery Reared Coho Salmon and Chinook Salmon during a Manipulative Thermal Experiment, Anchorage, Alaska 2020-2021 Gene Transcription and Heat Shock Protein 70 Abundance in Juvenile Hatchery Reared Coho Salmon and Chinook Salmon during a Manipulative Thermal Experiment, Anchorage, Alaska 2020-2021
This dataset consists of two tables with the results from two manipulative thermal experiments with juvenile coho salmon (May 2021) and juvenile Chinook salmon (May 2020) and include 1) gene transcription results and heat shock protein 70 abundance in coho salmon and Chinook salmon and 2) water temperatures to which fish were exposed during the experiment.
Reduced representation sequencing and genotyping of Arizona Toads (Anaxyrus microscaphus) from the southwestern United States Reduced representation sequencing and genotyping of Arizona Toads (Anaxyrus microscaphus) from the southwestern United States
The dataset consists of genotypes (diploid base calls at variant sites) at 3,601 anonymous sites of the Arizona Toad (Anaxyrus microscaphus) nuclear genome. The genotyped samples are representative of the range of the species and its major population units, and the genotyped loci have a high degree of completeness. This data release consists of several files: 1. sample.metadata.txt...
