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.

Soil-Water-Balance model and data for Phase 1 (2003–08) and Phase 2 (2018–23) hydrologic and water-budget analyses of the eastern part of the Arbuckle-Simpson aquifer, south-central Oklahoma, 2019–22 Soil-Water-Balance model and data for Phase 1 (2003–08) and Phase 2 (2018–23) hydrologic and water-budget analyses of the eastern part of the Arbuckle-Simpson aquifer, south-central Oklahoma, 2019–22
The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB) and the Oka' Institute, constructed a Soil-Water-Balance (SWB) model of the eastern part of the Arbuckle-Simpson aquifer in south-central Oklahoma. The SWB model was used to estimate recharge to the eastern part of the Arbuckle-Simpson aquifer between January 2019 and December 2022 for...
Data from Paleocene-Eocene sediments of three cores in the Salisbury Embayment, Maryland and Virginia Data from Paleocene-Eocene sediments of three cores in the Salisbury Embayment, Maryland and Virginia
The Surprise Hill core was drilled on the Northern Neck, Northumberland County, Virginia. The studied section consists of glauconitic quartz sands of the upper Paleocene Aquia Formation and silty clays of the lower Eocene Marlboro Clay. Data from this core were compared to the previously documented South Dover Bridge and Howards Tract cores from Maryland. The purpose of this study was to...
Detailed Aeromagnetic Survey of the Trinidad Area, California Detailed Aeromagnetic Survey of the Trinidad Area, California
This data release provides access to a low-altitude, aeromagnetic survey of a part of northwestern California. These data were acquired to support earthquake and tsunami hazard investigations and geologic mapping of the greater Trinidad area of northwestern California. Magnetic data are provided as a database and the residual magnetic intensity is provided as a grid.
Data from a road ecology study of Spotted Salamanders along the Natchez Trace Parkway, Mississippi, in 2012-2013 Data from a road ecology study of Spotted Salamanders along the Natchez Trace Parkway, Mississippi, in 2012-2013
This dataset contains study results examining the effect of road mortality on migrating salamanders along the Natchez Trace Parkway in Mississippi from 2012-2013. A combination of methods were used to assess the movement of salamanders to and from the breeding pond. Environmental variables such as air and water temperature, water salinity, and relative humidity were also collected during...
Data from time-constrained visual encounter surveys and acoustic surveys for amphibians and reptiles in the Atchafalaya Basin conducted from 2008 through 2016 Data from time-constrained visual encounter surveys and acoustic surveys for amphibians and reptiles in the Atchafalaya Basin conducted from 2008 through 2016
This dataset contains data from time-constrained visual encounter surveys conducted in the Atchafalaya River Basin in South Central Louisiana from February 2008 through July 2016. In addition, it contains vocalization data collected concurrently with the visual encounter surveys and data on presence of tadpoles and larvae. All participants in surveys are included in the dataset...
Summarized model outputs for a predator-prey-competitor model for Macrhybopsis and Scaphirhynchus in the Lower Missouri River Summarized model outputs for a predator-prey-competitor model for Macrhybopsis and Scaphirhynchus in the Lower Missouri River
Data represents summarized model outputs for various simulation scenarios performed used the Fish community bioenergetics model published at: https://doi.org/10.5066/P1XAZ6K9. A number of scenarios were explored to address specific queries regarding sturgeon-chub-invertebrate dynamics in the lower Missouri River. Data include a simulated pallid sturgeon maximum weight over time under...
