Data for A 3-D Seismic Velocity Model for Cascadia with Shallow Soils & Topography, Version 1.7 Data for A 3-D Seismic Velocity Model for Cascadia with Shallow Soils & Topography, Version 1.7
This data release contains three netCDF4 files containing grid points of P- and S-wave seismic velocities in Cascadia. This model is an update to Stephenson et al. (2017) Open-File Report 2017-1152, and contains a newly added shallow soil model and optional user-specified topography. A description of the model and its development is provided in the associated Open-File Report. The grid...
Observations of offset from shallow aseismic slip on the Concord fault, San Francisco Bay Area, CA Observations of offset from shallow aseismic slip on the Concord fault, San Francisco Bay Area, CA
The Concord fault is an active strike-slip fault of the Pacific-North America plate boundary that runs through suburban eastern San Francisco Bay Area, Contra Costa County, CA, in the cities of Concord and Walnut Creek. Recent work has identified ongoing aseismic slip along the trace of the fault and clarified its location. The data presented here record evidence of tectonic offsets of...
Deep learning classification of manganese and iron mines and prospects in the Lewisburg 30 x 60 minute quadrangle Deep learning classification of manganese and iron mines and prospects in the Lewisburg 30 x 60 minute quadrangle
Manganese is a designated critical mineral, being industrially utilized for producing steel and batteries, including in the production of electric vehicles (Rozelle and others, 2021). The central Appalachian Valley and Ridge hosts hundreds of manganese and iron oxide mines that served steel production until their abandonment in the mid-twentieth century (Lesure, 1957; Pegau, 1958). Many...
Mercury Concentrations and Light Stable Isotope Values for Invasive Black and White Tegus from the Greater Everglades, 2022-2024 Mercury Concentrations and Light Stable Isotope Values for Invasive Black and White Tegus from the Greater Everglades, 2022-2024
This dataset details mercury (Hg) concentrations and carbon, nitrogen, and sulfur isotopes for Black and White tegus (Salvator merianae) collected in and around Everglades National Park between 2022 and 2024. Tegus (n = 115) were collected from 54 sites. Mercury in tegu muscle tissue ranged from 4.1 to 1200 ng g-1. Additional matrices such as livers and blood were measured on a subset of...
Mercury Concentrations in Burmese Pythons Across the Greater Everglades Region in Florida from 2001 to 2022 Mercury Concentrations in Burmese Pythons Across the Greater Everglades Region in Florida from 2001 to 2022
Burmese Pythons are an invasive reptilian species that has spread throughout southern Florida. Mercury (Hg) concentration in python tail muscles were examined across the Great Everglades region in two periods, 2001 - 2011 and 2014 - 2019. The python samples collected spanned a large range of habitats, including wetland, forested, and urban areas. In 2022 tissues from the offspring six...
USGS National and Global Oil and Gas Assessment Project—Provinces of Mexico, Belize, and Guatemala—Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project—Provinces of Mexico, Belize, and Guatemala—Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources in the provinces of Mexico, Belize, and Guatemala. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil...
Oceanographic and hydrographic monitoring data of a shallow-water placement of dredged sediment in South San Francisco Bay, California, 2023-2025 Oceanographic and hydrographic monitoring data of a shallow-water placement of dredged sediment in South San Francisco Bay, California, 2023-2025
The U.S. Geological Survey Pacific Coastal and Marine Science Center collected oceanographic and hydrographic monitoring data for a pilot project to place dredged sediment in bay shallows to nourish marshes conducted by the US Army Corps of Engineers, San Francisco District. Dredged material was placed in the shallows of South San Francisco Bay during December 2023. Monitoring spanned...
Daily predictions of water temperature for streams across the contiguous United States (1979-2021) Daily predictions of water temperature for streams across the contiguous United States (1979-2021)
This model application data release provides the data processing and model code used to generate predictions of daily stream water temperature across the contiguous United States from 1979-2021. We used a recurrent graph convolutional network (RGCN) algorithm to make daily stream temperature predictions. Stream water temperature observations, along with forcing data consisting of daily
Pre- and post-fire modeled vegetation structure products for the Caldor, Cedar Creek, Dixie, KNP, and Muckamuck fires Pre- and post-fire modeled vegetation structure products for the Caldor, Cedar Creek, Dixie, KNP, and Muckamuck fires
Post-fire vegetation status and condition have multiple implications. They are indicative of burn severity and the lasting impacts of fire the land; they also help inform post-fire debris flow modeling and related risk analyses, hydrology and water quality assessments, and vulnerability to invasive species. Monitoring vegetation recovery over time enables continuous re-evaluation of...

Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, SDH, UWD) from January 1 to June 30, 2025. These data were collected in 2025 by Andria P. Ellis of the USGS Hawaiian Volcano Observatory.
3-Dimensional Point Clouds, Field Data, and Treelists from Three Montane Landscapes in New Mexico 3-Dimensional Point Clouds, Field Data, and Treelists from Three Montane Landscapes in New Mexico
These data include a collection of 3-dimensional (3D) point clouds from three New Mexico landscapes and associated field-collected validation data accompanying each scan. The data were collected in fall of 2022-2023 across three montane New Mexico landscapes - similar in climate but differing in disturbance histories. Landscapes include a intensely and repeatedly burned shrubfield, a...
Input and output data used to assess the effects of climate on the temporal variability in streamflow and total dissolved solids loads in the Upper Colorado River Basin, water years 1986-2021 Input and output data used to assess the effects of climate on the temporal variability in streamflow and total dissolved solids loads in the Upper Colorado River Basin, water years 1986-2021
