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.

Passive seismic depth to bedrock data collected along headwater stream corridors in the Neversink River watershed, NY, USA Passive seismic depth to bedrock data collected along headwater stream corridors in the Neversink River watershed, NY, USA
The Neversink River watershed (above the Neversink Reservoir) has been a focus of U.S. Geological Survey (USGS) research regarding stream geochemistry, acidification, and ecology dynamics for decades. In 2019, the Water Mission Area Next Generation Water Observing Systems Program augmented the existing stream gage network there, including instrumentation to specifically characterize...
SAR 2018 Native Fish Population and Habitat Study, Santa Ana and San Gabriel Rivers, California SAR 2018 Native Fish Population and Habitat Study, Santa Ana and San Gabriel Rivers, California
This dataset includes 2018 reach fish data and reach habitat data collected to support development of the upper Santa Ana River Habitat Conservation Plan for the Santa Ana Sucker (Catostomus santaanae) and the Arroyo Chub (Gila orcutti) in the Santa Ana and San Gabriel Rivers, California.
Numerical Simulation of 1D Advection-Dispersion Equation of Conservative Tracer with Oscillating Tidal Flows Numerical Simulation of 1D Advection-Dispersion Equation of Conservative Tracer with Oscillating Tidal Flows
Model archive for a numerical simulation of the one-dimensional advection-dispersion equation of a conservative tracer with oscillating tidal flows. The numerical simulation was used to examine how a conservative tracer evolves along a tidal channel. Scenarios were run to examine the effects increased dispersion, increased and decreased mixing at a channel junction, and increased...
Genetic Data for Merlin (Falco columbarius) and Cross-Species Microsatellite Amplification in Select Falco Species, North America Genetic Data for Merlin (Falco columbarius) and Cross-Species Microsatellite Amplification in Select Falco Species, North America
This data set contains allele sizes for 8 previously published and 16 novel microsatellite loci, and one microsatellite redesigned for amplification in Merlins (Falco columarius) associated with circadian clock control and polymorphism that has been associated with juvenile dispersal and migratory behavior in some avian species for Merlin (Falco columbarius) from North America (n=21)...
Machine-learning model predictions and rasters of dissolved oxygen probability, iron concentration, and redox conditions in groundwater in the Mississippi River Valley alluvial and Claiborne aquifers Machine-learning model predictions and rasters of dissolved oxygen probability, iron concentration, and redox conditions in groundwater in the Mississippi River Valley alluvial and Claiborne aquifers
Groundwater is a vital resource in the Mississippi embayment physiographic region (Mississippi embayment) of the central United States and can be limited in some areas by high concentrations of trace elements. The concentration of trace elements in groundwater is largely driven by oxidation-reduction (redox) processes. Redox processes are a group of biotically driven reactions in which...
Water temperature models, data and code for the Colorado, Green, San Juan, Yampa, and White rivers in the Colorado River basin Water temperature models, data and code for the Colorado, Green, San Juan, Yampa, and White rivers in the Colorado River basin
These data were compiled for a manuscript in which 1) we develop a water temperature model for the major river segments and tributaries of the Colorado River basin, including the Colorado, Green, Yampa, White, and San Juan rivers; 2) we link modeled water temperature to fish population data to predict the probability native and nonnative species will be common in the future in a warming...
