Travel Time and Dissolved Oxygen Data from August 2020 Along a 1-Mile Reach of the Blue River near 58th Street, Kansas City, Missouri Travel Time and Dissolved Oxygen Data from August 2020 Along a 1-Mile Reach of the Blue River near 58th Street, Kansas City, Missouri
These data were collected during a travel time and dissolved oxygen study along a 1-mile reach of the Blue River downstream from 58th Street in Kansas City, Missouri. The study was a cooperative effort between the U.S. Geological Survey (USGS), the U.S. Environmental Protection Agency Urban Waters Federal Partnership program, and the Kansas City, Missouri, Water Services Department.

Trend Estimates of Common Raven Populations in the United States and Canada, 1966 - 2018 Trend Estimates of Common Raven Populations in the United States and Canada, 1966 - 2018
These data identify the mean population growth rate and ratio change in abundance of common raven (Corvus corax; ravens) populations from 1966 through 2018, delineated by ecoregions defined by the U.S. Environmental Protection Agency. This enables researchers and land managers to identify regions which may be more heavily affected by growing raven populations. These data support the...
Tule Greater White-fronted Goose Migration Tracks (2019-2020) and Atmospheric Smoke Concentrations (2020). Tule Greater White-fronted Goose Migration Tracks (2019-2020) and Atmospheric Smoke Concentrations (2020).
April through May (spring) and August through September (fall) locations for tule greater white-fronted geese (Anser albifrons elgasi) marked with GPS collars at Summer Lake Wildlife Area, OR in 2018 and 2019. Locations may include pre-migration and post-migration designations. Locations occurring between September 11, 2020, and arrival at, or within 50 kilometers of the Summer Lake...
Tungsten skarn mineral resource assessment of the Great Basin region of western Nevada and eastern California - Geodatabase Tungsten skarn mineral resource assessment of the Great Basin region of western Nevada and eastern California - Geodatabase
A mineral resource assessment for tungsten, a critical mineral commodity (see 'Related External Resources' section below) for the United States, was carried out by the U.S. Geological Survey (USGS) for a portion of the Great Basin region, in western Nevada and eastern California, between latitudes 36N and 42N and longitudes 116W and 120W. This study (Lederer and others, in review)...
Tungsten skarn mineral resource assessment of the Great Basin region of western Nevada and eastern California - Simulation results Tungsten skarn mineral resource assessment of the Great Basin region of western Nevada and eastern California - Simulation results
The dataset consists of the input data, parameters, and results output from mineral resource assessment calculations.
U-Pb age determinations of uraninite by electron microprobe analyses of ore samples from two solution-collapse breccia pipe uranium deposits, Grand Canyon region, northwest Arizona, USA U-Pb age determinations of uraninite by electron microprobe analyses of ore samples from two solution-collapse breccia pipe uranium deposits, Grand Canyon region, northwest Arizona, USA
This data release compiles the electron microprobe spot analyses of U, Th, and Pb concentrations in uraninite (U oxide) particles, and corresponding calculated age determinations, measured in samples of ore from two uranium-copper breccia pipe ore bodies, the Canyon (Pinyon Plain) and Hack II deposits. The U-rich samples that were analyzed typify the deposits hosted by solution-collapse...
U-Pb ages of detrital zircons in Paleogene strata of the Gulf Coast U-Pb ages of detrital zircons in Paleogene strata of the Gulf Coast
This data release contains 60 detrital zircon age spectra, based on U and Pb isotope ratio measurements for 9399 single grains. The samples are from Paleogene strata of the U.S. Gulf Coast. Of the 9399 single grain measurements, we recommend that 8640 yield ages that are suitable for construction of detrital zircon age spectra. Comments tagged to individual grains explain the reasoning...
U-Pb Isotopic Data and Ages of Zircon from the Manzano Mountains, New Mexico U-Pb Isotopic Data and Ages of Zircon from the Manzano Mountains, New Mexico
This data set contains tables containing uranium-lead (U-Pb) isotopic data and the crystallization age of zircon from a metamorphic rock from the Manzano Mountains, New Mexico, collected in 2005. The bulk sample was processed into concentrated mineral separates of zircon at the University of Texas at Austin and analyzed by U.S. Geological Survey (USGS) research scientists at the Stanford...
U-Pb zircon data for: Upper Triassic and Jurassic sedimentary rocks from Sonora, MX U-Pb zircon data for: Upper Triassic and Jurassic sedimentary rocks from Sonora, MX
This laser ablation ICPMS U-Pb zircon data set supports stratigraphic, biostratigraphic and age interpretations of the of the fossil-plant-bearing El Game?o Formation of west-central Sonora, Mexico and the potentially age-correlative fossil-plant-bearing Santa Clara and Coyote formations of southeastern Sonora, Mexico. The zircon data provides minimum age constraints (maximum...
U.S. Geological Survey and U.S. Army Corps of Engineers Bathymetric Survey of Lake Koocanusa, Lincoln County, Montana, 2016-2018 U.S. Geological Survey and U.S. Army Corps of Engineers Bathymetric Survey of Lake Koocanusa, Lincoln County, Montana, 2016-2018
In 2016, the U.S. Army Corps of Engineers (USACE) started collecting high-resolution multibeam echosounder (MBES) data on Lake Koocanusa. The survey originated near the International Boundary (River Mile (RM) 271.0) and extended down the reservoir, hereinafter referred to as downstream, about 1.4 miles downstream of the Montana 37 Highway Bridge near Boulder Creek (about RM 253). USACE...
U.S. Geological Survey Bathymetric and Topobathymetric Survey Inventory, version 1 U.S. Geological Survey Bathymetric and Topobathymetric Survey Inventory, version 1
The 3DEP U.S. Geological Survey (USGS) Inland Bathymetric and Topobathymetric Survey Inventory for the conterminous US is a database for digital, geospatial three-dimensional bathymetric and topobathymetric datasets created as a resource for public and private science and engineering analyses and modeling. Initiated in 2018, the database includes all published USGS inland to coastal...
U.S. Register of Introduced and Invasive Species (US-RIIS), all versions U.S. Register of Introduced and Invasive Species (US-RIIS), all versions
This is the landing page for all versions of the United States Register of Introduced and Invasive Species (US-RIIS). The US-RIIS is comprised of three lists, one each for Alaska (AK), Hawaii (HI), and the conterminous United States (L48). Each list includes taxonomic and ecological information about introduced (non-native), established (reproducing) taxa that: are, or may become...
