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.

Groundwater and soil gas data, methods, and quality assurance information for samples collected to determine ancient carbon distributions at Red Hill, Bulk Fuel Storage Facility, O‘ahu, Hawai‘i 2022-2023 Groundwater and soil gas data, methods, and quality assurance information for samples collected to determine ancient carbon distributions at Red Hill, Bulk Fuel Storage Facility, O‘ahu, Hawai‘i 2022-2023
This U.S. Geological Survey (USGS) Data Release describes field methods, lab methods, and data for groundwater and soil gas samples collected in the vicinity of the Red Hill Bulk Fuel Storage Facility, O‘ahu, Hawai‘i, from September 2022 through April 2023. 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...
