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.

Landslides Triggered by the 2025 M8.8 Kamchatka Peninsula, Russia Earthquake Landslides Triggered by the 2025 M8.8 Kamchatka Peninsula, Russia Earthquake
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...
Data for barrier island resilience and resistance: analysis and metrics for characterizing state Data for barrier island resilience and resistance: analysis and metrics for characterizing state
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...
Permeameter test results on open-graded friction course pavement on Interstate 95 in Needham, Massachusetts, 2018-2025 Permeameter test results on open-graded friction course pavement on Interstate 95 in Needham, Massachusetts, 2018-2025
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...
Data supporting an integrated approach to decoding the paleoenvironmental and diagenetic signatures of ancient phosphorites Data supporting an integrated approach to decoding the paleoenvironmental and diagenetic signatures of ancient phosphorites
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...
Geochemical Data for Mercury and Other Constituents in Shallow Sediment and Porewater from Clear Lake, Lake County, California Geochemical Data for Mercury and Other Constituents in Shallow Sediment and Porewater from Clear Lake, Lake County, California
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...
Near Surface Spatial Water Quality Data Matched with Satellite Imagery and Discrete Phytoplankton Data in the Lower Hudson River New York, 2021-2023 Near Surface Spatial Water Quality Data Matched with Satellite Imagery and Discrete Phytoplankton Data in the Lower Hudson River New York, 2021-2023
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...
