Site characterization, with the goal of measuring VS30, was performed at 27 strong motion stations across Central and Southern California. These stations, belonging to the National Strong Motion Program, spanned four counties and varied geophysical environments. Primarily employed were the Simplified Site Characterization Methods (SSCM) as an efficient yet robust method for measuring...

This data release describes data that were contributed to the GasHype project, a global data compilation effort. Goals of the GasHype project include assessing concentrations of carbon dioxide and methane in the hypolimnion of lakes, reservoirs, and ponds, and identifying important drivers of these concentrations. Data contributed by the U.S. Geological Survey, Northern Prairie Wildlife...

The Simplified Site Characterization Method (SSCM) was employed to obtain VS30 data at 39 sites across California. These geophysical surveys utilized both active- and passive-source methods wherever site conditions allowed. Primary focus was on characterization of seismic stations. Major regions surveyed include the San Francisco Bay Area, Anza Valley, Imperial Valley, Los Angeles, and...

We collected electrofishing, environmental DNA (eDNA), and habitat data from 2022 to 2024 in the Oregon portion of the Goose Lake Basin. Data were collected by the U.S. Geological Survey (USGS) and Oregon State University (OSU) to monitor native and non-native fish distributions in the Basin, and to relate observed abundances to specific habitat features. Sampling was conducted in...

The stable hydrogen (delta 2H) and oxygen (delta 18O) isotopic compositions of more than 1,400 daily or weekly composite samples of precipitation from four National Atmospheric Deposition Program (NADP) sites (VA10, VA27, VA28, and WV99) in Virginia and West Virginia were analyzed on archived samples obtained from NADP over various time periods from as early as 1998. The samples are from...

Climate change is a pervasive and growing global threat to the supply and demand of ecosystem goods and services that maintain human well-being. A recent review found that the impacts of climate change on ecosystem services are sometimes mixed, posing challenges for managers who need to adapt to these changes. We expand on earlier work by exploring drivers of varying responses of...

This data release reformats data fields from the STATSGO soil characteristics dataset (Schwarz and Alexander, 1995) as cloud-optimized GeoTIFFs (COGs). The COG format allows standard software tools to efficiently access the datasets over an internet connection. Please refer to the documentation of the source archive (Schwarz and Alexander, 1995) for additional details on the underlying...

These data are associated with occurrences of nine-banded armadillos across the United States. There are associated biological and environmental variables associated with some of the occurrence data. These were used for a species distribution model.

Important hydrological and geotechnical information from U.S. Geological Survey (USGS) reports detailing selected paleotectonic geologic periods, including the Jurassic (McKee and others, 1956), Triassic (McKee and others, 1959), Permian (McKee and McKee, 1967), Pennsylvanian (McKee and Crosby, 1975), and Mississippian (Craig and Connor, 1979), were digitized from scanned plates...

This dataset is one table with demographic, morphometric, and blood analyte measurements from whole blood and serum samples taken from a subset of polar bears sampled in Alaska's southern Beaufort Sea during 1989-2012. The measured blood analytes include: blood urea nitrogen, creatinine, glucose, total protein, hemoglobin, red blood cell count, packed cell volume, and hemoglobin A1c...

This data release contains the watershed ancillary data that were used as input for a set of dynamic Spatially Referenced Regression On Watershed attributes (SPARROW) models for watersheds draining to Puget Sound and the Strait of Juan de Fuca, Washington for the years 2005 - 2020. The SPARROW models were used to estimate mean seasonal total nitrogen and total phosphorous conditions and...

Bathymetric, topographic, and grain-size data were collected in April 2011 along a 27-mi (43.5 – km) reach of the Colorado River in Grand Canyon National Park, Arizona. The study reach begins at river mile 61.1, about 0.6 -mi (1 –km) above the confluence of the Colorado and Little Colorado Rivers and ends at river mile 88.1 at the upstream boundary of the Bright Angel Rapid (Phantom...
