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.

Sea-level rise and high tide flooding inundation probability and depth statistics in Nassau and Duval Counties, Florida Sea-level rise and high tide flooding inundation probability and depth statistics in Nassau and Duval Counties, Florida
This dataset includes elevation-based probability and depth statistics for estimating inundation under various sea-level rise and high tide flooding scenarios in and around the National Park Service’s Timucuan Ecological and Historic Preserve. These datasets were developed using 1-m digital elevation model (DEM) from 2018 with reduced elevation error in coastal wetlands (McHenry and...
Cone Penetration Test data of Paleoliquefaction sites in Washington and Oregon Cone Penetration Test data of Paleoliquefaction sites in Washington and Oregon
In many parts of the United States and around the globe, the instrumental earthquake record is insufficient to characterize seismic hazard or constrain potential ground motion intensities from individual sources. This lack of data is particularly acute for the Cascadia Subduction Zone (CSZ) of the U.S. Pacific Northwest, where paleoseismic evidence suggests a long history of large...
FLOwPER Database: StreamFLOw PERmanence field observations, Jan 2021 - Dec 2021 FLOwPER Database: StreamFLOw PERmanence field observations, Jan 2021 - Dec 2021
IMPORTANT NOTE: This dataset includes spatial locations where streamflow permanence observations (continuous flow, discontinuous flow, and dry) were recorded using the FLOwPER (FLOw PERmanence) field survey available in the Survey 123. Additional information to describe the field conditions are included as part of the survey. Field observations in the FLOwPER Database have not been...
Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2023 Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2023
Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) Network stations for the period 1985 through 2023. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach...
Modeled Nutrient and Sediment Concentrations from Major Rivers in Illinois Based on Continuous Monitoring from October 1, 2015, through September 30, 2022 Modeled Nutrient and Sediment Concentrations from Major Rivers in Illinois Based on Continuous Monitoring from October 1, 2015, through September 30, 2022
During water years 2016–2022 (a water year begins on October 1 and ends on September 30), the U.S. Geological Survey (USGS), in cooperation with the Illinois Environmental Protection Agency (Illinois EPA), operated continuous monitoring stations on eight of the major rivers in Illinois to better quantify nutrient and sediment loadings from the State of Illinois to the Mississippi River...
Airborne electromagnetic and magnetic survey of the Alabama Graphite-Vanadium Belt and surrounding regions, 2023 Airborne electromagnetic and magnetic survey of the Alabama Graphite-Vanadium Belt and surrounding regions, 2023
Airborne electromagnetic (AEM) and magnetic survey data were collected during March and April 2023 over a distance of 9,000 line kilometers in east central Alabama. Data were acquired by SkyTEM Canada Inc. with the SkyTEM 306HPM time-domain helicopter-borne electromagnetic system together with a Geometrics G822A cesium vapor magnetometer. The survey was acquired at a nominal flight...
