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.

Cave climate data in Wood Valley pit crater, Hawai'i Cave climate data in Wood Valley pit crater, Hawai'i
Wood Valley Pit Crater is a nearly circular pit approximately 50m across and 50m deep with vertical walls. This pit is of particular interest because it hosts access to a cave entrance at its base, providing an opportunity to monitor cave climate throughout a type of cave structure that is ordinarily inaccessible. In-situ cave climate observations included cold trapping, cave breathing...
Ice cave climate data and frost imagery at Sunset Crater, AZ: 02 March 2021 to 13 December 2022 Ice cave climate data and frost imagery at Sunset Crater, AZ: 02 March 2021 to 13 December 2022
The purpose of the data collection was to monitor the microclimate in the “Bonito Flow” Ice Cave located in Sunset Crater National Monument. This cave is considered a sacred spot for some southwestern tribes as it was a historical source for ice. The main purpose of the climate monitoring was to determine if the cave is still an active ice cave, i.e., a cave that contains perennial ice...
Pathogen Exposure Data for Chukchi Sea Polar Bears 1988-1994 and 2008-2017 Pathogen Exposure Data for Chukchi Sea Polar Bears 1988-1994 and 2008-2017
This dataset is one table with results of tests to determine exposure of Chukchi Sea polar bears to a suite of pathogens. Results are serological tests for antibodies and tests of fecal samples for presence of parasites. Serologic assays were conducted for Toxoplasma gondii, Neospora caninum, Francisella tularensis, Coxiella burnetii, Leptospira spp., Brucella canis, Brucella abortus...
Postfire erosion estimates for large California wildfires that occurred between 1984 and 2021 Postfire erosion estimates for large California wildfires that occurred between 1984 and 2021
This data release presents a compilation of postfire sediment mobilization data from wildfires greater than 100 km2 that occurred in California or regions of southern Oregon that drain to the California coast between 1984 and 2021. This compilation includes three sources of sediment mobilization data: hillslope erosion modeled using the Water Erosion Prediction Project (WEPP) postfire...
Database for the Geologic Map of the Katmai Volcanic Cluster, Katmai National Park, Alaska Database for the Geologic Map of the Katmai Volcanic Cluster, Katmai National Park, Alaska
A database of the geologic map of the Katmai Volcanic Cluster as described in the original abstract: This digital publication contains all the geologic map information used to publish U.S. Geological Survey Geologic Investigations Map Series I-2778 (Hildreth and Fierstein, 2003). This is a geologic map of the Katmai volcanic cluster on the Alaska Peninsula (including Mount Katmai...
Enhanced Terrain Imagery of the Staunton 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution Enhanced Terrain Imagery of the Staunton 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution
This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Staunton 30 x 60 minute quadrangle in West Virginia and Virginia. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2015 and 2021. The data were processed using...

High resolution natural color imagery collected by uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 2-mile reach of the Middle Green River at Grays Canyon near Green River, Utah from 2021-2023 High resolution natural color imagery collected by uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 2-mile reach of the Middle Green River at Grays Canyon near Green River, Utah from 2021-2023
The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 2-mile reach of the Middle Green River at Grays Canyon near Green River, UT. Visual imagery was collected in jpg format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et. al. 2021)...
