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.

The Red Hill facility consists of 20 underground fuel storage tanks that can each hold approximately 12.5 million gallons of fuel...
2019 Eastern Iowa Topographic Lidar Validation – USGS Field Survey Data 2019 Eastern Iowa Topographic Lidar Validation – USGS Field Survey Data
U.S. Geological Survey (USGS) scientists conducted field data collection efforts between October 25th and 31st, 2020 at several sites in eastern Iowa using high accuracy surveying technologies. The work was initiated as an effort to validate commercially acquired topographic light detection and ranging (lidar) data that was collected between December 7th, 2019 and November 19th, 2020...
MetaIPM: A Meta-population Integral Projection Model v 2.0 MetaIPM: A Meta-population Integral Projection Model v 2.0
MetaIPM is a Python package (Python Software Foundation 2020) that models meta-population dynamics and continuous growth rates via an integral projection model (IPM) for species living in distinct habitat patches. The package stems from a model that compares invasive carp population control strategies (Erickson et al. 2018). For example, Erickson et al. (2017) used an R predecessor...
MODFLOW 6 models for assimilating remote sensing evapotranspiration in ensemble-based framework to enhance cascade routing and re-infiltration concept in integrated hydrological models applied to support decision making MODFLOW 6 models for assimilating remote sensing evapotranspiration in ensemble-based framework to enhance cascade routing and re-infiltration concept in integrated hydrological models applied to support decision making
This data release contains MODFLOW 6 integrated hydrological model (IHM) that helps characterize the groundwater/surface-water interaction within the Sardon Catchment of western Spain. The model was used to quantify and reduce the overall model uncertainty to improve its reliability as a Decision Support Modeling (DSM) tool by improving the conceptualization and simulation of the...
MODPATH model to simulate particle transport in groundwater near Puget Sound, Pierce County, Washington MODPATH model to simulate particle transport in groundwater near Puget Sound, Pierce County, Washington
MODPATH simulations were performed using the MODFLOW groundwater flow model by Wright and others (2023) as the basis, with particles originating from 5 separate areas in or near Joint Base Lewis-McChord (JBLM). Steady-state and transient runs were performed, with transient runs representing 2005-2015 conditions. This data release contains the input and output files for the simulations...
GIS data for U.S. Geological Survey OFR 2005-1252, The Geologic Map of Seattle—A Progress Report GIS data for U.S. Geological Survey OFR 2005-1252, The Geologic Map of Seattle—A Progress Report
This data release contains the GIS data supporting U.S. Geological Survey Open-File Report (OFR) 2005-1252, "The Geologic Map of Seattle—A Progress Report," published in 2005 by Kathy Goetz Troost, Derek B. Booth, Aaron P. Wisher, and Scott A. Shimel (https://doi.org/10.3133/ofr20051252). The OFR was prepared for the 2005 Washington Hydrogeology Symposium and describes the status of...
Results from dynamic cone penetration testing of soils on the Utuado Batholith, upland and dissected terrains, Puerto Rico – March 2022 Results from dynamic cone penetration testing of soils on the Utuado Batholith, upland and dissected terrains, Puerto Rico – March 2022
A Smart Dynamic Cone Penetrometer (DCP) system allows for the partially automated collection of cone penetrometer data (CPT) to determine mechanical properties of soil along a vertical profile. A smart DCP system was used to collect soil penetration-with-depth values at 16 sites along three transects on the Utuado Batholith, a late Cretaceous age granodiorite pluton located on the...
Seismic sub-bottom, sediment core and radiocarbon data collected in Ozette Lake, Washington from 2019-2021 Seismic sub-bottom, sediment core and radiocarbon data collected in Ozette Lake, Washington from 2019-2021
Seismic-reflection data and cores were collected in Ozette Lake, Washington, from 2019 to 2021. These data were used to investigate submarine landslide deposits triggered by large Cascadia Subduction Zone earthquakes. Identification of fault-related submarine hazards is a primary mission of the USGS Coastal and Marine Geology Program. In the US Pacific Northwest region, the greatest...

This data release contains input for and outputs from hydrologic simulations of the upper Pipestem creek basin located in the Prairie Pothole region of North Dakota using the Precipitation Runoff Modeling System (PRMS).These simulations were developed to provide example applications of model calibration using alternative calibration targets. These PRMS model input and output data are...
Data to support an updated range map for Plethodon shenandoah and evaluating support for multiple models of species occurrence (ver. 2.0, August 2025) Data to support an updated range map for Plethodon shenandoah and evaluating support for multiple models of species occurrence (ver. 2.0, August 2025)
The Shenanadoah Salamander (Plethodon shenandoah) is an endangered salamander found only in the mountains of Shenandoah National Park. Field surveys of the salamander were conducted from 2007-2022 using daytime cover object surveys. In order to capture the totality of P. shendandoah’s range we sampled from low to high elevation across a broad geographic range. We created a spatial...
Rasters and Tables for Selection and Survival of Greater Sage-grouse Nests and Broods in the Bi-State Distinct Population Segment of California and Nevada Rasters and Tables for Selection and Survival of Greater Sage-grouse Nests and Broods in the Bi-State Distinct Population Segment of California and Nevada
We demonstrate a quantitative approach to differentiate source and sink habitats at large spatial scales using the greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse), an indicator species for sagebrush ecosystems, as a case-study. We evaluated both selection and survival across multiple reproductive life stages (nesting, brood-rearing) in the Bi-State Distinct...
