Data

This dataset contains absolute-gravity measurements made using an A-10 absolute gravity meter (Micro-g Lacoste, Inc.) in 2008, 2009, 2017, 2018, and 2019 in the Hualapai Valley, Mohave County, Arizona. Measurements were made at 9 different stations. Data are presented in tabular form, including relevant parameters used for processing. Data were output by g software (Micro-g Lacoste, Inc.) version

This data release contains trend results computed on the basis of modeled and observed daily streamflows at 1,257 gages across the conterminous U.S. from October 1, 1983 through September 30, 2016. Study gages were selected from the GAGES-II dataset of gages classified as non-reference which means streamflows may be affected by human influence. Modeled daily streamflows were computed using the det

This U.S. Geological Survey (USGS) Data Release is focused on the geochemistry of wells within the oil zone and groundwater monitoring wells away from the oiled zone at the National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji MN (USA) from 1985-2015. The site located in Beltrami County is where a high-pressure pipeline carrying crude oil burst in 1979 and spilled approximat

This dataset contains the final water-level records (334) that met all threshold criteria and had an absolute residual (ABS_PSEUDO_LEV) of less than 20 feet. The threshold of 20 feet was selected based on water-level changes of the U.S. Geological Survey groundwater site 363551090152801 Qulin, in the Mississippi River Valley alluvial aquifer. This final dataset is considered a best representation

A Geographic Information System (GIS)? shapefile and summary tables of irrigated agricultural land-use are provided for Broward and Miami-Dade Counties, Florida compiled through a cooperative project between the U.S Geological Survey and the Florida Department of Agriculture and Consumer Services, Office of Agricultural Water Policy. Information provided in the shapefile includes the locations in

The U.S. Geological Survey collected water-quality samples from 3,199 sites between May 2004 and April 2022 for the California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP). The GAMA-PBP is a cooperative project with the California State Water Resources Control Board (SWRCB). The primary objectives of the GAMA-PBP are: (1) to assess the quality of groundwa

We used an automated radio telemetry network to document the activity of radio telemetered Hawaiian forest birds in two study sites, one a continuous forest and the other a fragmented forest. Four bird species were studied: the nectarivorous 'i'iwi (Drepanis coccinea) and 'apapane (Himatione sanguinea), the frugivorous 'oma'o (Myadestes obscurus), and the generalist Hawai'i 'amakihi (Chlorodrepani

The U. S. Geological Survey- Water Resources Mission Area is currently developing Integrated Water Availability Assessments (IWAAs) - multi-extent (regional and national), stakeholder driven, near real-time water availability census and prediction for human and ecological uses. To provide appropriate user accessibility to data delivery systems developed for IWAAs, a user-centered design process in

This data release contains a comprehensive, spatially referenced database of surface-water transfer and removal events in the Pacific drainages of the United States, which include the Columbia River basin, the Puget Sound basin, the coastal drainages of Washington, Oregon, and California, and the Central Valley of California. The database also includes mean annual estimates of the water diverted a

Proposed invasive carp barriers may threaten populations of migratory fishes in the St. Croix National Scenic Riverway and the Mississippi National River and Recreation Area by preventing movements between rivers needed to fulfill life history requirements. Moreover, reproducing populations of invasive carp could alter aquatic food webs and negatively affect mussels and migratory fishes. In this s

Peak ground velocity (PGV) gridded probabilistic seismic hazard data for the updated 2018 National Seismic Hazard Model (NSHM) for the Conterminous United States (CONUS). PGV hazard curves and ground motions have been calculated on a 0.05 by 0.05 degree grid using the NSHM CONUS 2018 earthquake source model. PGV support has been incorporated into the NSHM using a newly developed PGV model conditio
