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.

Detrital Zircon U-Pb data from selected Appalachian rivers and Outer Banks-area coastal sediments Detrital Zircon U-Pb data from selected Appalachian rivers and Outer Banks-area coastal sediments
U-Pb isotopic data from zircon grains from the sediment bedload of seven modern rivers: the Susquehanna, Potomac, Roanoke, James, Peedee, Tar, and Cape Fear, as well as from three samples taken from beaches in Albemarle and Pamlico Sounds (North Carolina), two Pleistocene core samples, and three samples on the ocean-facing foreshore of the Outer Banks barrier islands (North Carolina and...
Delaware River Basin Stream Salinity Machine Learning Models and Data Delaware River Basin Stream Salinity Machine Learning Models and Data
This model archive contains the input data, model code, and model outputs for machine learning models that predict daily non-tidal stream salinity (specific conductance) for a network of 459 modeled stream segments across the Delaware River Basin (DRB) from 1984-09-30 to 2021-12-31. There are a total of twelve models from combinations of two machine learning models (Random Forest and...
Compilation of water-quality data, discharge data, and geochemical equilibrium models for streams, draining mine adits, and springs in the Upper Animas River Watershed, Colorado, 1987–2020 Compilation of water-quality data, discharge data, and geochemical equilibrium models for streams, draining mine adits, and springs in the Upper Animas River Watershed, Colorado, 1987–2020
Acid mine drainage (AMD) can cause ecological harm throughout the state of Colorado, including in the Upper Animas River watershed near Silverton. In the Upper Animas River watershed, a technique that includes the emplacement of hydraulic bulkheads within draining mines has been used to remediate AMD. Data for major ions and trace metal concentrations, isotopic compositions, and...
Demographic Measurements to Inform a Brood Translocation Integrated Population Model Demographic Measurements to Inform a Brood Translocation Integrated Population Model
Wildlife managers translocate greater sage-grouse (Centrocercus urophasianus; sage-grouse) to augment small populations, but translocated sage-grouse often fail to reproduce post-release, sometimes hampering conservation objectives. We performed two distinct sage-grouse translocation projects in California and North Dakota from 2017-2020 and employed two translocation methods at both...
