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.

Database for the Geologic Map of Three Sisters Volcanic Cluster, Cascade Range, Oregon Database for the Geologic Map of Three Sisters Volcanic Cluster, Cascade Range, Oregon
A database of geologic map of Three Sisters Volcanic Cluster as described in the original abstract: The geologic map represents part of a late Quaternary volcanic field within which scores of eruptions have taken place over the last 50,000 years, some as recently as ~1,500 years ago. No rocks of early Pleistocene (or greater) age crop out within the map area, although volcanic and...
Juvenile Shorebird Morphological Data Collected in Alaska and Canada Juvenile Shorebird Morphological Data Collected in Alaska and Canada
This dataset consists of shorebird chick measurements (wing, primary feather 10, diagonal tarsus, and bill length) and body mass for various shorebird species captured in Alaska and Canada during 1978-2022. Researchers with the U.S. Geological Survey - Alaska Science Center, and collaborators from many government agencies and research institutions have studied shorebirds at numerous...
Impervious Land Cover Raster Derived from the National Land Cover Dataset (NLCD) 2019 for South Carolina StreamStats Impervious Land Cover Raster Derived from the National Land Cover Dataset (NLCD) 2019 for South Carolina StreamStats
In cooperation with the South Carolina Department of Transportation, the U.S. Geological Survey prepared a geospatial raster dataset describing impervious surface in the SC StreamStats study area derived from the 30m resolution National Land Cover Dataset (NLCD) 2019. This layer, which covers the SC StreamStats study area, has been resampled from the source resolution to a scale of 30ft...
Pharmaceuticals and personal care products measured in passive samplers at seven coastal sites off West Maui during February and March 2017 Pharmaceuticals and personal care products measured in passive samplers at seven coastal sites off West Maui during February and March 2017
Passive membrane samplers—semipermeable membrane devices and polar organic chemical integrative samplers—were deployed for 22 continuous days at 7 sites along the West Maui, Hawai'i, coastline in February and March 2017 to assess organic contaminants at shallow coral reef ecosystems from diverse upstream inputs.
High Resolution Daily Global Alfalfa-Reference Potential Evapotranspiration Climatology High Resolution Daily Global Alfalfa-Reference Potential Evapotranspiration Climatology
Global alfalfa-reference potential evapotranspiration (ETr) is a key model parameter in actual evapotranspiration (ETa) modeling for worldwide applications. This dataset was constructed for use with the Operational Simplified Surface Energy Balance (SSEBop) model as a key driver of the final ETa magnitude. SSEBop is a parametric energy balance-based model that determines actual ET as the...
Literature review results and regulatory summaries of freshwater stressors influencing biological impairment in the Chesapeake Bay watershed, USA Literature review results and regulatory summaries of freshwater stressors influencing biological impairment in the Chesapeake Bay watershed, USA
This data release contains relevant datasets used in the analysis for the Chesapeake Bay stressor identification project, for which results are described in Fanelli and others (in review). For this project, two existing information sources were compiled and summarized to identify key in-stream stressors reported by the scientific literature or through regulatory assessments to be likely...
