Data Releases

High-resolution multichannel seismic reflection data and chirp sub-bottom data were collected by the U.S. Geological Survey in July and August 2017 offshore southeast Alaska to expand data coverage along the Queen Charlotte Fault system. Data were acquired to study earthquake hazards, fault mechanics and submarine mass wasting processes along the Queen Charlotte fault system, a 1200 km long transf

Datasets of suspended sediment concentration and percent fines, sampling information, and daily streamflow data were compiled and harmonized for 16 sites to better understand sediment transport and delivery in the Lower Mississippi and Atchafalaya Rivers. The compiled data were harmonized by removing unnecessary columns, screening data for laboratory or sampling issues, creating consistent entries

This dataset contains two predictive lek (breeding site) persistence raster layers covering the U.S. greater sage-grouse distribution. In the United States, locations where males display and breed with females (i.e., leks) are often monitored annually by state wildlife agencies, providing valuable information on the persistence of birds in the surrounding areas. A U.S. range-wide lek database was

Bats play crucial ecological roles and provide valuable ecosystem services, yet many populations face serious threats from various ecological disturbances. The North American Bat Monitoring Program (NABat) aims to assess status and trends of bat populations while developing innovative and community-driven conservation solutions using its unique data and technology infrastructure. To support scalab

This data release contains products from Savoy & Harvey (2021) which modeled photosynthetically active radiation and gross primary productivity (GPP) for 173 streams and rivers across the continental United States. Estimates of photosynthetically active radiation (PAR) were generated using a model that considers the contribution of light attenuation from riparian zones as well as within the water

Field-verified irrigated lands data were collected for the Remote Sensing Component of the St. Mary-Milk Rivers Consumptive Use study to aid in the identification and delineation of agricultural fields that are irrigated in 2021 and 2022 in the Milk River basin. This field verification of irrigated fields will provide data that will be used to ground truth evapotranspiration estimates obtained in

In 2021, the U.S. Geological Survey (USGS), in cooperation with the National Geological and Geophysical Data Preservation Program, cataloged and scanned notes and calculations for indirect measurements taken during flood events in Montana. This product provides a publicly available catalog of the field notes, photos, survey information, and calculations for indirect measurements at selected sites.

This U.S. Geological Survey (USGS) data release represents the Minnesota component of the National Water-Well Database (NWWDB). The NWWDB is a compilation of water-well records from state-managed databases that have been standardized to a common format for consistency across state and administrative boundaries. Water-well completion reports that are submitted to permitting state agencies by licens

This USGS data release consists of 15 geospatial datasets for Smith Valley and Mason Valley, west-central Nevada, including contours representing groundwater levels based on depth-to-water measurements, groundwater-level change rasters calculated from groundwater-level contours, groundwater-level change rasters calculated from depth-to-water point values, and groundwater monitoring well locations

This U.S. Geological Survey data release contains data for Smith Valley, Nevada, digitized from plate 2 of the 1976 publication: Rush, F.E.,and Schroer, C.V., 1976, Geohydrology of Smith Valley, Nevada with special reference to the water-use period 1953-72: Nevada Department of Conservation and Natural Resources Water Resources Bulletin 43, 43p. Data are for spring 1972 and include groundwater-lev

This U.S. Geological Survey data release contains data for Smith and Mason Valleys, California and Nevada, from the 2009 publication: Lopes, T.J.,and Allander, K.K., 2009, Hydrologic Setting and Conceptual Hydrologic Model of the Walker River Basin, West-Central Nevada: U.S. Geological Survey Scientific Investigations Report 2009–5155, https://doi.org/10.3133/sir20095155. Data include (1) 1:24,000

This digital dataset contains the climate data used for the Lower Salinas Valley Hydrologic Models (Salinas Valley Integrated Hydrologic Model (SVIHM) and Salinas Valley Operational Model (SVOM)). The monthly climate data for the Lower Salinas Valley Hydrologic Models are based on the regional climate data for the Salinas Valley Hydrologic System [Hevesi and others, 2022]. To develop the monthly c
