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.

Aerial imagery and structure-from-motion derived data products from a UAS survey of the debris flow at South Fork Campground, Sequoia National Park, CA Aerial imagery and structure-from-motion derived data products from a UAS survey of the debris flow at South Fork Campground, Sequoia National Park, CA
This data release presents aerial imagery and digital topography to support a geohazards assessment for an area of Sequoia National Park affected by debris flows in January 2023. Multiple atmospheric-river storms brought heavy precipitation to Sequoia National Park and the surrounding region in December 2022 and January 2023, triggering slope failures. Storm rainfall on January 9, 2023...
Geochemistry of ferromanganese crusts, nodules, and coated cobbles from seamounts in the Papahānaumokuākea Marine National Monument Geochemistry of ferromanganese crusts, nodules, and coated cobbles from seamounts in the Papahānaumokuākea Marine National Monument
Ferromanganese crusts, nodules, and coated cobbles were collected via ROV from seamounts off the coast of Hawaii and within the Papahānaumokuākea Marine National Monument (PMNM) in the Pacific Ocean during E/V Nautilus expeditions NA134 and NA138 in 2021 and 2022, respectively. Ferromanganese rock samples were sent to USGS for subsampling, major and trace element geochemical analyses...
LANDFIRE 2023 (240) Update LANDFIRE 2023 (240) Update
The LANDFIRE 2023 Update (LF 2023) product suite represents the final step in the ongoing goal to move towards annual updates and reduced latency. LANDFIRE'S goal has been to release an annual update every year that represents one year, specifically the previous year. Similar to the LF 2022 Update, in LF 2023, disturbances from the previous year are represented in current year products...
Phytoplankton assemblage dynamics in relation to environmental conditions in a riverine lake: Upper Mississippi River Phytoplankton assemblage dynamics in relation to environmental conditions in a riverine lake: Upper Mississippi River
Phytoplankton samples were collected from Lake Pepin (a natural, riverine lake on the Upper Mississippi River) from 2012-2014. The dataset includes phytoplankton community data (i.e., genus, species, biovolume, etc.), as well as zooplankton, rotifer, cladoceran and water quality data.
Fish sampling data, water temperature data, and groundwater spring location data from the upper Snake River basin, WY, 2021-2023 Fish sampling data, water temperature data, and groundwater spring location data from the upper Snake River basin, WY, 2021-2023
Fish sampling data, stream temperature data, and observations of the locations of groundwater springs within the upper Snake River basin, Wyoming. These datasets were created to assess how stream temperature and groundwater spring sources are associated with the growth and production of young-of-year Yellowstone cutthroat trout (Oncorhynchus virginalis bouvieri; formerly Oncorhynchus...
Digital elevation models (DEMs) of the beach and nearshore in Santa Cruz, California Digital elevation models (DEMs) of the beach and nearshore in Santa Cruz, California
This data release presents digital elevation models (DEMs) derived from bathymetric and topographic measurements collected offshore of Santa Cruz, CA, from 2014 to 2024. Bathymetry data were collected using two personal watercraft (PWCs), each equipped with single-beam echosounders and survey-grade global navigation satellite system (GNSS) receivers. Topography data were collected on...
