Data Releases

This data release presents geologic map data for the surficial geology of the Overton, Lake Mead, and Las Vegas 30-minute by 60-minute quadrangles, Arizona, Utah, and Nevada. This 1:100,000 scale geologic mapping incorporates new interpretive contributions and compilation from 1:24,000 to 1:250,000 scale published geologic map data sources. Geology incorporated from previous mapping has...

The dataset contains observational records of encounters of meadow voles (Microtus pennsylvanicus) trapped at Eastern Ecological Science Center (formerly Patuxent Wildlife Research Center) in Laurel, Maryland, USA. Animals were trapped using Sherman traps from 23 September 1991 to 24 August 1993. Data collected included id, date, age, sex, weight, location and reproductive status.

Wildfire can substantially alter the hydrologic response of watersheds to rainfall, and debris-flow activity is among the most destructive consequences of these events. To assist federal, state, and local agencies in planning for postfire hazards, the U.S. Geological Survey conducts debris-flow hazard assessments for recent wildfires. This collection holds all postfire debris-flow hazard

We present an inventory of 346 landslides triggered by the July 29, 2025 M8.8 Kamchatka Peninsula, Russia earthquake. Landslides were mapped from 10 meter resolution openly available Sentinel-2 optical images. All landslides were manually identified by comparing pre- (using cloud free images as close to the earthquake date as possible from July 2024 - 2025) and post-earthquake real color...

This data release includes information and metrics for evaluating the geomorphic state of barrier islands and headlands along coastal Louisiana. Specifically, these data are: 1) subaerial land coverage; 2) vegetated area coverage; 3) subaerial volume to area ratio from publicly available light detection and ranging (lidar) elevation data; 4) inundation extent (i.e., maps) for high tide...

Open-graded friction course (OGFC) pavement is a layer of porous asphalt spread over the surface of impervious dense-graded hot-mix asphalt that is traditionally used as the wearing surface in Massachusetts. Benefits of OGFC pavement include noise reduction, less vehicular spray, hydroplaning, and surface reflectivity, and often provides measurable improvements in concentrations of...

Phosphorites are significant geological deposits that serve as key archives of past marine productivity, biogeochemical cycling, and sedimentary processes, as well as critical reservoirs of phosphorus, an essential element for global agriculture. Herein we investigate Late Cretaceous phosphorite deposition in Israel, which occurred in an extensive phosphorite belt spanning from Turkey to...

Clear Lake, located in Lake County, California, is impacted by mercury contamination associated with the historic Sulfur Bank mercury mine, which is adjacent to the lake’s eastern shore / Oaks Arm region. As part of a larger study designed to better understand the biogeochemical cycling of mercury in Clear Lake, shallow sediment (top 0-2 cm or 0-4 cm) was sampled from the three major...

This data release contains phytoplankton, water-quality, and satellite data from thirteen surveys along the lower Hudson River, extending from Yonkers to Troy, New York. Data were collected between August 2021 and October 2023. These surveys included continuous water-quality measurements collected at 10-second intervals using a multiparameter sonde deployed in a boat-mounted flow-through...

Data tables and data references supporting the journal article titled: "Estimated average annualized losses from potential building damage and fatalities due to earthquake-generated tsunamis in the United States." Earthquake-generated tsunamis represent substantial economic threats to states and territories in the United States (U.S.), but we are unaware of any effort to quantify...

Data that support the journal article titled “Earthquake-hazard exposure of populations with potential access and functional needs in the United States” as described here: Earthquake response plans and earthquake early warning (EEW) systems designed for general populations may not consider potential access and functional needs (AFN) of individuals with physical, sensory, cognitive, or...

This data release provides digital flight-line and gridded data for a high-resolution airborne magnetic and radiometric survey over a part of west central Utah. The survey was acquired as part of the UGSS Earth Mapping Resource Initiative (Earth MRI) to improve our understanding of the fundamental geologic framework of the region with applications to evaluating natural resources and...
