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.

Shear-wave velocity surface seismic site characterization data at 21 sites in Puerto Rico Shear-wave velocity surface seismic site characterization data at 21 sites in Puerto Rico
In collaboration with researchers at the University of Puerto Rico, Mayaguez, the U.S. Geological Survey acquired multimethod surface seismic imaging data at 21 sites in Puerto Rico for shear-wave velocity site characterization. These data were collected at both permanent and temporary seismograph stations throughout the island, between March 6 and March 18, 2022. Data were acquired...
Gridded earthquake ground motions for the 2023 ASCE/SEI 41 Standard outside of the conterminous United States Gridded earthquake ground motions for the 2023 ASCE/SEI 41 Standard outside of the conterminous United States
For evaluating and retrofitting existing buildings to resist earthquakes, the 2023 ASCE/SEI 41 Standard provides Basic Safety Earthquake spectral response accelerations at four levels (BSE-1N, BSE-2N, BSE-1E, and BSE-2E). This data release covers BSE-1E and BSE-2E spectral response accelerations for sites outside of the conterminous United States. For sites in the conterminous U.S., BSE...
Pesticide Concentrations Measured in Zooplankton Samples Collected from the Sacramento River, Yolo Bypass, and Cache Slough Region, California, 2024 Pesticide Concentrations Measured in Zooplankton Samples Collected from the Sacramento River, Yolo Bypass, and Cache Slough Region, California, 2024
Zooplankton samples were collected in the summer/fall of 2024 at multiple sites in the Sacramento River, Yolo Bypass, and Cache Slough Region of California and analyzed for a suite of 160 current-use pesticides and pesticide degradates by the U.S. Geological Survey Organic Chemistry Research Laboratory. Samples were collected at two sites in the Bypass, at a comparison site on the...
Stable carbon (C13) and nitrogen (N15) isotopic values of American alligators within the Florida Everglades (2013-2020) Stable carbon (C13) and nitrogen (N15) isotopic values of American alligators within the Florida Everglades (2013-2020)
This dataset contains morphometric and isotopic data for American alligators (Alligator mississippiensis) that were sampled from within four freshwater (FW) wetlands and one estuarine (EST) wetland within the Greater Everglades ecosystem. Due to their compartmentalization and varied habitat and water regimes, there were multiple sampling sites within two of the FW wetlands. The five...
Data for the evaluation of the acute toxicity of 4-nitro-3-(trifluoromethyl)phenol (TFM) to Burbot (Lota lota) Data for the evaluation of the acute toxicity of 4-nitro-3-(trifluoromethyl)phenol (TFM) to Burbot (Lota lota)
The dataset provides access to all data used in the interpretation of results for the study including dose response curves from toxicity tests, predicted minimum lethal concentration data, water quality data, and mortality data.
Summary from posterior distributions of multistate movement model for silver carp in the upper Mississippi River from 2014 to 2021 Summary from posterior distributions of multistate movement model for silver carp in the upper Mississippi River from 2014 to 2021
This data contains the mean and standard deviations for movement rates for silver carp in the upper Mississippi River 2014 and 2021. The data are summaries of the posterior distribution from a Bayesian multistate model described in Stanton et al. 2024 (https://doi.org/10.7717/peerj.17834).
