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.

Measurements of vegetation, soil, and disturbance following utility-scale solar energy development in the Mojave Desert, 2021-2023 Measurements of vegetation, soil, and disturbance following utility-scale solar energy development in the Mojave Desert, 2021-2023
These data were compiled to evaluate the impact of a utility-scale solar energy (Gemini Solar + Storage) development on ecosystem function in the Mojave Desert. Objectives of our study were to identify the short-term effects of construction on soils and vegetation across plant communities and soil types. These data represent a before-after control-impact study to evaluate the effects of...
Dissolved methane and CO2 concentrations and stable carbon isotopes from the coastal Arctic landscape of the Greiner Lake watershed, Nunavut, Canada in June 2022 and June-July 2023 Dissolved methane and CO2 concentrations and stable carbon isotopes from the coastal Arctic landscape of the Greiner Lake watershed, Nunavut, Canada in June 2022 and June-July 2023
A watershed in the coastal Canadian Arctic was sampled for dissolved carbon dioxide and methane concentration and stable carbon (carbon-13) isotopes to trace the transport, production, and consumption of carbon dioxide and methane during the spring thaw across a lake to bay transect. Two field campaigns were conducted in June 2022 and June-July 2023 out of the Canadian High Arctic...
Climate Change Vulnerability Index Release 4.0: Excel Workbook Climate Change Vulnerability Index Release 4.0: Excel Workbook
The Climate Change Vulnerability Index (CCVI) uses a scoring system that integrates a species’ exposure to projected climate change within an assessment area, including sea level rise, and three sets of factors associated with climate change sensitivity, each supported by published studies: 1) species-specific sensitivity and adaptive capacity factors, 2) threat multipliers such as...
Arcata, California, Distributed Acoustic Sensing (DAS) experiment: 2022 M6.4 Ferndale Aftershock Sequence (ver. 3.0, February 2026) Arcata, California, Distributed Acoustic Sensing (DAS) experiment: 2022 M6.4 Ferndale Aftershock Sequence (ver. 3.0, February 2026)
These data are from a Distributed Acoustic Sensing (DAS) experiment in Arcata, CA, that was conducted jointly by the U.S. Geological Survey, Cal Poly Humboldt University, and Luna Inc. A Luna QuantX DAS interrogator was installed in the Arcata Police Station and connected to a fiber owned by Vero Communications that runs from Arcata to Eureka (Figure 1). The interrogator was installed on...
Hawai'i National Hydrologic Model (NHM) application,1980–2021 Hawai'i National Hydrologic Model (NHM) application,1980–2021
This data release contains inputs for and outputs from hydrologic simulations for the Hawai‘i (HI) domain using the Precipitation Runoff Modeling System (PRMS) version 5.2.1.1 for the precalibration, by Hydrologic Response Unit (byHRU) release, and by Point Of Interest Observation (byPOIobs) release using the USGS National Hydrologic Model infrastructure (NHM; Regan and others, 2018)...
Citations in Environmental Assessments Prepared by the Bureau of Land Management in Colorado from 2015-2019 Citations in Environmental Assessments Prepared by the Bureau of Land Management in Colorado from 2015-2019
These data support a study with the purpose of better understanding science and data use in Federal public lands decisions in the United States. To do this, we assessed the number, type, and age of documents cited in 70 Environmental Assessments (EAs) completed by the Bureau of Land Management (BLM) in Colorado from 2015-2019. We focused on the BLM, as they manage the largest area of...
