Following the 2018 collapses of the caldera floor at the summit of Kīlauea Volcano (Anderson and others, 2019; Neal and others, 2019), the enlarged and deepened depression hosted a variety of volcanic activity between 2019 and 2022. These events included an unprecedented water lake and two prolonged episodes of lava lake activity. This data release includes images from a stationary thermal camer

This data release includes measurements of the surface elevation of the lava lake within Halemaʻumaʻu crater, at the summit of Kīlauea Volcano, during the 2008-2018 summit eruption (Patrick and others, 2021). The data were measured by several instruments (laser rangefinder, webcams, lidar) and are compiled here to provide the most complete dataset yet available on the elevation of Kīlauea’s 2008-

In 2018, a large effusive eruption on the lower flank of Kīlauea Volcano was associated with collapse and subsidence of the summit caldera floor (Neal and others, 2019).  The bottom of Halemaʻumaʻu, a crater nested within the summit caldera, subsided by more than 500 m.  In July 2019, water was observed ponding on the deepest part of the Halemaʻumaʻu crater floor and the water rose and enlarged in

This dataset contains hourly vehicle traffic counts in the Kuparuk and Milne Point oil fields on the North Slope of Alaska during summers 2019 and 2020. The oil field roads were generally closed to the public during the study period, so traffic was primarily associated with industrial activities. Data were collected using TRAFx vehicle traffic counters (TRAFx Research Ltd, Canmore, Alberta, Canada

This dataset is associated with potential source rock samples collected from Uzbekistan. Borehole core samples, as well as outcrop samples, were collected by Uzbek GOSCOMGeology and the USGS in 2021 and 2022. Samples were sent to GeoMark Source Rock Lab for Leco total organic carbon content and HAWK pyrolysis analysis. Analysis results include percent carbonate (wt%), Leco TOC (wt%), and HAWK pyro

This data release summarizes suspended sediment monitoring results on the Chehalis (USGS 12031000), Satsop (USGS 12035000) and Wynoochee (USGS 12037400) Rivers between water years 2019 and 2022. Sediment monitoring was based on a combination of continuous turbidity records and discrete suspended-sediment concentration (SSC) measurements. Data and results for each monitoring station were combined i

This data release contains the boundaries of assessment units, assessment input data and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in the Barents Sea Area. The Assessment Unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined

The winter rainy season of 2016-2017 brought abundant rainfall to the state of California, including the San Francisco Bay region. Thousands of shallow landslides were triggered as a result of saturated soils and intense rainfall from strong winter storms in January and February 2017. The highest concentration of landslides from these storms occurred in the eastern part of the bay region, where la

The U.S. Geological Survey (USGS) has compiled national shoreline data for more than 20 years to document coastal change and serve the needs of research, management, and the public. Maintaining a record of historical shoreline positions is an effective method to monitor national shoreline evolution over time, enabling scientists to identify areas most susceptible to erosion or accretion. These dat

Greater sage-grouse (Centrocercus urophasianus) has been identified as a potential umbrella species with the assumption that conservation of their habitats in sagebrush ecosystems may benefit multiple other wildlife species, but co-occurrence with an umbrella species does not necessarily guarantee species will respond positively to management for sage-grouse. This may be particularly true for ecot

The information provided in the Contaminant Exposure and Effects-Terrestrial Vertebrates (CEE-TV) Database profiles available geo-referenced information on contaminant exposure and effects in terrestrial vertebrates along the U. S. Atlantic, Gulf, and Pacific coasts (including Hawaii and Alaska) and the Great Lakes.

The Russian River Watershed (RRW) covers about 1,300 square miles (without Santa Rosa Plain) of urban, agricultural, and forested lands in northern Sonoma County and southern Mendocino County, California. Communities in the RRW depend on a combination of Russian River water and groundwater to meet their water-supply demands. Water is used primarily for agricultural irrigation, municipal and privat
