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.

Data to Assess Nitrogen Export from Forested Watersheds in and near the Long Island Sound Basin with Weighted Regressions on Time, Discharge, and Season (WRTDS) Data to Assess Nitrogen Export from Forested Watersheds in and near the Long Island Sound Basin with Weighted Regressions on Time, Discharge, and Season (WRTDS)
The U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency's Long Island Sound Study (https://longislandsoundstudy.net), characterized nitrogen export from forested watersheds and whether nitrogen loading has been increasing or decreasing to help inform Long Island Sound management strategies. The Weighted Regressions on Time, Discharge, and Season (WRTDS...
FlowDat: Volcanic Mass Flow Database FlowDat: Volcanic Mass Flow Database
Volcanic mass flows, especially lahars and pyroclastic density currents (PDCs) are among the most destructive volcanic hazards due to their speed, mobility, and the often-unexpected behavior these flows exhibit as they interact with topography. Mitigation of risk associated with PDCs and other volcanic mass flows depends upon accurate forecasting of magnitude and frequency, potential...
Occurrence Data for the Western Spadefoot (Spea hammondii) in Southern California From 1995 to 2020 and Projected Species Distribution Model Occurrence Data for the Western Spadefoot (Spea hammondii) in Southern California From 1995 to 2020 and Projected Species Distribution Model
These data represent the results of surveys for western spadefoots in southern California, including both presence and non-detection data. In addition, data include environmental covariates that were hypothesized to influence the occurrence of western spadefoots, such as land cover and distance to aquatic features. These data support the following publication: Rose, J.P., Halstead, B.J
The North American Breeding Bird Survey, Analysis Results 1966 - 2023 The North American Breeding Bird Survey, Analysis Results 1966 - 2023
This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 546 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross
Soil-water-balance model and data used in the hydrogeologic investigation, framework, and conceptual flow model of the Antlers aquifer, southeastern Oklahoma, 1967–2022 Soil-water-balance model and data used in the hydrogeologic investigation, framework, and conceptual flow model of the Antlers aquifer, southeastern Oklahoma, 1967–2022
This archive contains the data used to (1) summarize the hydrogeology and update the hydrogeologic framework of the Antlers aquifer in southeastern Oklahoma, and (2) develop a conceptual groundwater-flow model and water budget to estimate recharge to the Antlers aquifer during 1980–2022 as part of a hydrologic investigation (the model documentation report is available at https://doi.org...
Whole-Rock Geochemical Data for Cenozoic Silicic Igneous and Hydrothermal Rocks from Colorado, New Mexico, Arizona, Nevada, and California Whole-Rock Geochemical Data for Cenozoic Silicic Igneous and Hydrothermal Rocks from Colorado, New Mexico, Arizona, Nevada, and California
This data release presents whole-rock geochemical data for a suite of silicic igneous and magmatic-hydrothermal rocks from the western Cordillera of the United States. Samples were mainly collected from Eocene to Miocene high-silica igneous rocks and other nearby igneous and hydrothermal±magmatic rocks. These data were collected to help define highly evolved magma systems that can be...
