Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including...

This data release provides a monthly irrigation water use reanalysis for the period 2000-20 for all USGS Watershed Boundary Dataset of Subwatersheds (HUC12) in the conterminous United States (CONUS). Results include reference evapotranspiration (ETo), actual evapotranspiration (ETa), irrigated areas, consumptive use, and effective precipitation for each HUC12. ETo and ETa were estimated using the operational Simplified Surface Energy Balance (SSEBop, Senay and others, 2013; Senay and others, 2020) model executed in the OpenET (Melton and others, 2021) web-based application implemented in Google Earth Engine. Results provided by OpenET/SSEBop were summarized to hydrologic response units (HRUs) in the National Hydrologic...

The National Science Foundation Ice Core Facility (NSF-ICF) - formerly the U.S. National Ice Core Laboratory (NICL) - is a facility for storing, curating, and studying meteoric ice cores recovered from glaciated regions of the world. NSF-ICF provides scientists with the capability to conduct examinations and measurements on ice cores, and it preserves the integrity of these ice cores in a long-term repository for current and future investigations.

Note: this data release has been depecrated. Find the updated version here: https://doi.org/10.5066/P942QL23 In June, 2022, the Mount Rainier Streamflow Permanence model was revised to replace monthly climatic covariates with seven-month summaries to address peer-review comments related to inclusion of correlated covariates into the model. Replacement of the monthly covariates resulted in changes to the model source code and model outputs, which are now annual probabilities of streamflow permanence for years 2018-2020. This data release contains spatially gridded geospatial data (rasters), R scripts, and supporting files to run Random Forest models to predict the probability of late summer surface flow in Mt....

A data and code repository for studies conducted as part of the Delaware River Basin (DRB) Integrated Water Availability Assessments program. The community serves as a site where hydrologic, physical, chemical, biological, and landscape data can be stored and used for modeling and geospatial analysis to improved understanding of water availability in the DRB.

The USGS-NPS Vegetation Characterization Program is a cooperative effort by the U.S. Geological Survey (USGS) and the National Park Service Inventory & Monitoring - Vegetation Inventory Program to classify, describe, and map vegetation communities in more than 280 national park units across the United States. Through this undertaking a variety of data and information on vegetation is being made available to Internet users through this website. Vegetation in each of the participating park units is described and mapped using the National Vegetation Classification Standard of the Federal Geographic Data Committee. Use of the national standard opens up exciting opportunities to develop and share more comparable vegetation...
