All Data

These data are from a Distributed Acoustic Sensing (DAS) experiment in Arcata, CA, that was conducted jointly by the U.S. Geological Survey, Cal Poly Humboldt University, and Luna Inc. A Luna QuantX DAS interrogator was installed in the Arcata Police Station and connected to a fiber owned by Vero Communications that runs from Arcata to Eureka (Figure 1). The interrogator was installed on...

This data release contains inputs for and outputs from hydrologic simulations for the Hawai‘i (HI) domain using the Precipitation Runoff Modeling System (PRMS) version 5.2.1.1 for the precalibration, by Hydrologic Response Unit (byHRU) release, and by Point Of Interest Observation (byPOIobs) release using the USGS National Hydrologic Model infrastructure (NHM; Regan and others, 2018)...

These data support a study with the purpose of better understanding science and data use in Federal public lands decisions in the United States. To do this, we assessed the number, type, and age of documents cited in 70 Environmental Assessments (EAs) completed by the Bureau of Land Management (BLM) in Colorado from 2015-2019. We focused on the BLM, as they manage the largest area of...

This data release contains the concentration and quality-assurance results for inorganic constituents, organic compounds (volatile organic compounds [VOC], per- and polyfluoroalkyl substances [PFAS], pesticides, and disinfection byproducts [DBP]) collected in tapwater from locations in Alabama and Mississippi. Tapwater samples (11 public supply and 1 private well) were collected on...

We hypothesized that bighorn sheep ewes with chronic nasal Mycoplasma ovipneumoniae carriage are the source of infection that results in fatal lamb pneumonia. We tested this hypothesis in captive bighorn ewes at two study facilities over a 5-year period, by identifying carrier ewes and then comparing lamb fates in groups that did (exposed pens) or did not (non-exposed pens) include one...

The survey was conducted to assess the distribution of terrapins in the Chesapeake Bay, based on evidence related to nesting. We conducted a survey of the beaches during the nesting season in the summer of 2002. We walked along the shoreline of over 1350 beach segments looking for evidence signifying the presence of terrapins based on nesting activity. These results represent a single...

This data release contains results of a study investigating changes in streamflow seasonality associated with hydroclimatic variability in the north-central United States, including nine States (Illinois, Iowa, Michigan, Minnesota, Missouri, Montana, North Dakota, South Dakota, and Wisconsin). Peak-flow records from unregulated U.S. Geological Survey streamgages were used to evaluate...

These data describe estimates of large-bodied fish activity and their direction of movement with respect to a restored wetland located in Ottawa National Wildlife Refuge, Oak Harbor, Ohio, USA. Acoustic sonar technology was used to monitor fish activity following restoration and reconnection of a hydrologically isolated wetland pool to the wider Lake Erie system. Fish activity was...

The M9.2 1964 Great Alaska earthquake is the second-largest earthquake in the historical record, the largest in North America, and involved nearly five minutes of shaking (Brocher and others, 2014). The earthquake initiated in the Alaska-Aleutian subduction zone, about 12 km below northern Prince William Sound. The rupture length was about 700 km and generated deep and shallow...

This data release provides supplementary information supporting our study on seismic intensities, ground motions, and basin amplification during the Mw 6.4 Ferndale, California earthquake of December 20th, 2022. A field survey was conducted between January 9-12 and March 6-9 in 2023 to assess the damage and shaking intensity experienced across the affected areas. During this survey, 17...

Landslide susceptibility models show the potential of landslide occurrence at a location. These models are pivotal for reducing losses associated with landslides (Godt and others, 2022). In this data release, we include susceptibility results from the associated manuscript by Woodard and Mirus (2025). This manuscript shows how a morphometric model can create consistent and effective...

In 2023, the U.S. Geological Survey, in cooperation with Riverside Energy Michigan, LLC, conducted an injection experiment to monitor the natural rate of biogenic methane generation in the Mortensen A4-24 well which was completed in the Antrim Shale and located in Antrim County, Michigan, United States of America. Approximately 20 barrels (bbl) of produced water was pumped from the well...
