Data

This Data Release contains two compilations provide information on the date of the last known earthquake in the U.S. where available (conterminous U.S. and Alaska). There are two spatial datasets with different feature geometries — line features (“HistDOLE_v1”) and point features (“PaleoDOLE_v1”). The line features describe surface ruptures constrained by historical or near-historical...

Oaks were mapped in a portion of Yolo County, California, USA. For 26 focal trees, acorn counts were conducted from 2013-2023. Trees were located in rural and urban areas. Rural trees were located visually and location was recorded. Urban tree locations were drawn from randomly distributed point locations at 1.2 valley oaks per hectare. The data also include distance between oak trees to...

This data release contains grain size and total carbon analysis of sediment samples from 1 inch hand-augered cores collected from Barter Island, Alaska. These data were collected in 2016 and 2019 (USGS Field Activity 2016-645-FA and 2019-634-FA). Data include location information (latitude, longitude, depth), and the weight percent of 65 phi bins, four size fractions (gravel, sand, silt...

This data release contains water level observations from a sensor grid deployed in the tidal marshes of the Charles H. Wheeler Wildlife Management Area in the central Long Island Sound (Connecticut, USA). Water level sensors were deployed between August 2018 and December 2018 to serve as a calibration/validation (cal/val) dataset for the development, refinement, and evaluation of remote...

This data release contains files supporting the publication “Landslide volume estimation from seismic waveform features using a global catalog of seismogenic events” (Collins and others, 2026). Events.csv lists each landslide event used in the publication, published event ids, names, times, locations, and volumes taken from Seismogenic Landslides and other Mass Movements (ver. 3.0, May...

The data release contains spatial data sets in raster and vector formats that are used to quantify, analyze and visualize recent fire regimes for the Mogollon Rim-Colorado Plateau (also called the Mogollon Highlands), the Sky Islands, or Madrean Archipelago and the Northern Sierra Madre Occidental regions of the United States and Mexico. The data were generated as part of the Southwest...

The U.S. Geological Survey is developing national water-use models to support water resources management in the United States. Model benefits include a nationally consistent estimation approach, greater temporal and spatial resolution of estimates, efficient and automated updates of results, and capabilities to forecast water use into the future and assess model uncertainty. In this data...

These datasets includes physical and geochemical lab results of sediment samples collected from August 2017 to October 2018. Upland samples were collected at randomly selected sites in the watershed using the geographic information system (GIS) site-selection procedure. Three sets of passive suspended-sediment samplers were installed and sampled monthly. Streambank and streambed sediment...

These datasets includes physical and geochemical lab results of sediment samples collected from October 2016 to February 2018. Upland samples were collected at randomly selected sites in the watershed using the geographic information system (GIS) site-selection procedure. Passive suspended-sediment samplers were installed at three sites and sampled monthly. Streambank and streambed...

The East River is an agricultural tributary to the Lower Fox River and the Environmental Protection Agency (EPA) Green Bay Area of Concern (AOC) in northeast Wisconsin. This tributary has known excessive phosphorus (P) and suspended sediment loads that contribute to habitat related impairments and downstream algal blooms. As part of the Great Lakes Restoration Initiative (GLRI), the U.S

This data release contains measurement‑accuracy information derived from angler‑reported fish lengths submitted through a smartphone mobile application. The dataset includes records from multiple fishing events across the United States and Canada in which participating anglers self‑reported total length (TL) for each catch. Lengths were subsequently reviewed and verified by app staff...
