Telemetry based determination of first-year survival for lake sturgeon reintroduced to the Maumee River Telemetry based determination of first-year survival for lake sturgeon reintroduced to the Maumee River
Lake sturgeon (Acipenser fulvescens) have experienced large population declines due to overfishing, habitat degradation, and pollution. Due to these factors, lake sturgeon were extirpated in the Maumee River watershed (Ohio, USA). In 2018, a 20-year reintroduction program began that aims to establish a self-sustaining population in the Maumee River. To understand the potential success of...
Data for assessment of mineral commodity supply risk 2018 Data for assessment of mineral commodity supply risk 2018
Data for Figure 2 of U.S. Geological Survey Open-File Report 2021-1045 titled "Methodology and Technical Input for the 2021 Review and Revision of the U.S. Critical Minerals List." The data include the disruption potential, economic vulnerability, trade exposure, and overall supply risk for various mineral commodities in 2018. For some commodities, indicator scores are rounded to avoid
Visible and Near Infrared (VNIR) and Short Wavelength Infrared (SWIR) Spectra of Select Altered Mafic and Ultramafic Rock Samples from the Josephine Peridotite in CA and OR, the Yukon-Tanana region in Alaska, and from the Southern Appalachians in VA, NC, Visible and Near Infrared (VNIR) and Short Wavelength Infrared (SWIR) Spectra of Select Altered Mafic and Ultramafic Rock Samples from the Josephine Peridotite in CA and OR, the Yukon-Tanana region in Alaska, and from the Southern Appalachians in VA, NC,
These data are laboratory reflectance measurements conducted on a suite of altered mafic and ultramafic rocks. Visible-Near InfraRed (VNIR) and Short-Wave InfraRed (SWIR) reflectance measurements were made (~0.4 – 2.5 microns) using an artificial light source connected to an Analytical Spectral Devices (ASD) spectrometer. Spectra from a total of 91 samples were measured and analyzed...
Digital elevation models, orthomosaics, and GIS shapefiles of the 2020–2021 summit eruption at Kīlauea volcano, Island of Hawaiʻi Digital elevation models, orthomosaics, and GIS shapefiles of the 2020–2021 summit eruption at Kīlauea volcano, Island of Hawaiʻi
During the 2020–2021 summit eruption of Kīlauea volcano, Island of Hawaiʻi, staff at the U.S. Geological Survey Hawaiian Volcano Observatory (HVO) conducted 17 helicopter overflights of the eruption area between the dates of 21 December 2020 and 8 June 2021. Images captured during these flights were processed using the structure-from-motion (SfM) photogrammetry technique to produce...
Island of Hawaii ROD tree inoculation study, 2019-2022 Island of Hawaii ROD tree inoculation study, 2019-2022
This data release includes metadata and tabular data that documents the response of ohia (Metrosideros polymorpha) and ambrosia beetles (Curculionidae, Xyleborini) following the intentional inoculation of healthy ohia to Ceratocystis lukuohia, one of two fungal pathogens that causes Rapid Ohia Death (ROD). Ohia were inoculated with the ROD pathogen at three sites differing in elevation...
Slash Pile Characteristics and their Relationship to Habitat for Sacramento Mountain Salamanders, New Mexico USA Slash Pile Characteristics and their Relationship to Habitat for Sacramento Mountain Salamanders, New Mexico USA
This data package contains six tables: 1) slash pile characteristics, 2) soil moisture and temperature below and nearby slash piles, 3) measurements of individual logs within slash piles, 4) characteristics of log cover objects nearby slash piles, 5) locations and body measurements of Sacramento Mountain salamanders (Aneides hardii) found under or within slash piles or individual log...
Trace element concentrations in streambed sediment and aquatic invertebrates in post-wildfire watersheds in the western United States Trace element concentrations in streambed sediment and aquatic invertebrates in post-wildfire watersheds in the western United States
The U.S. Geological Survey is monitoring concentrations of metals and other trace elements in streambed sediment and aquatic invertebrates in post-wildfire watersheds in five western states including California, Oregon, Montana, Colorado and New Mexico. This data release makes available major and minor trace element concentrations in bed sediment and aquatic invertebrates collected from...
River margin and braid shapefiles digitized from aerial images of the Elwha River, Washington, 2006 to 2022 River margin and braid shapefiles digitized from aerial images of the Elwha River, Washington, 2006 to 2022
This dataset provides GIS shapefiles of river margins and braids derived from 30 aerial imagery datasets of the Elwha River, Washington spanning June 2006 through September 2022. The extent of the river’s recently active flow zone, or margins, and river braids was manually digitized in a GIS using aerial orthoimages to capture changes in the river prior to, during, and after the removal...
Tabular uranium-lead and trace-element compositional data of zircons and whole-rock geochemistry of plutonic rocks in the Sierra Nevada, California Tabular uranium-lead and trace-element compositional data of zircons and whole-rock geochemistry of plutonic rocks in the Sierra Nevada, California
This dataset consists of zircon uranium-lead (U-Pb) isotopic compositions, ages, and trace-element compositions in addition to whole-rock chemical compositions from plutons within the Sierra Nevada, California. These samples primarily collected from 2015 to 2023, although some legacy data are included. Zircon crystals were analyzed using the Sensitive High-Resolution Ion Micro-Probe...
Water and sediment geochemistry in the Gallinas Creek Watershed, New Mexico following the Hermits Peak-Calf Canyon fire 2022-2023 Water and sediment geochemistry in the Gallinas Creek Watershed, New Mexico following the Hermits Peak-Calf Canyon fire 2022-2023
This data set was collected throughout the Gallinas watershed in New, Mexico following the Hermit's Peak-Calf Canyon fires on April 6, 2022. The watershed has a history of mining and prospecting, which acts as an additional stressor to post-wildfire water quality and ecosystem health. Water samples were collected immediately post-fire. Water, sediment deposit and bed sediment samples...
Ground-Based LIDAR Data of a Section of the Point Bonita Lighthouse Trail, Golden Gate National Recreation Area, Marin County, California, January 23, 2025 Ground-Based LIDAR Data of a Section of the Point Bonita Lighthouse Trail, Golden Gate National Recreation Area, Marin County, California, January 23, 2025
A rockfall occurred between the night of January 5 and the morning of January 6, 2025 on the Point Bonita Trail in the National Park Service Golden Gate National Recreation Area, California. The rockfall originated from a granodiorite rock face in the Franciscan Formation and deposited approximately 25 cubic meters of rock on the pedestrian trail below. The U.S. Geological Survey...
