Data for the Estimation of Regional Flow-Duration Curves for Indiana and Illinois (ver. 3.0, December 2021) Data for the Estimation of Regional Flow-Duration Curves for Indiana and Illinois (ver. 3.0, December 2021)
Digital datasets were used to develop basin characteristics whose values are used in multiple regression equations and tested for the use in predicting flow-duration curves (FDCs) in ungaged areas of Illinois and Indiana. Several basin characteristics are easily derived from StreamStats (https://streamstats.usgs.gov/ss/) basin delineations themselves, such as basin area and basin...
High-Resolution Aeromagnetic Survey of the Cle Elum Area, Washington High-Resolution Aeromagnetic Survey of the Cle Elum Area, Washington
This data release provides access to a low-altitude, aeromagnetic survey of a part of central Washington centered approximately 22 km west-southwest of Ellensburg. The survey includes the cities of Ellensburg, Cle Elum, and Yakima and is referred to as the Cle Elum aeromagnetic survey. The Cle Elum aeromagnetic survey extends from the Columbia Plateau westward to the eastern Cascade...
High-Resolution Aeromagnetic Survey Over the New Madrid Seismic Zone, Missouri, Arkansas, and Tennessee High-Resolution Aeromagnetic Survey Over the New Madrid Seismic Zone, Missouri, Arkansas, and Tennessee
This data release provides access to a low-altitude, aeromagnetic survey over parts of Missouri, Arkansas, and Tennessee, an area centered about 100 km north of Memphis, Tennessee. The survey covers parts of the southern arm of the New Madrid seismic zone, the northwestern margin of the Reelfoot rift, the Blytheville arch, and the Commerce geophysical lineament (reference: Langenheim, V...
High-Resolution Aeromagnetic Survey Over Pendleton, Oregon, and Surrounding Areas High-Resolution Aeromagnetic Survey Over Pendleton, Oregon, and Surrounding Areas
This data release provides access to a low-altitude, aeromagnetic survey over a part of northeastern Oregon, an area centered approximately over the city of La Grande. The survey is underlain by pre-Tertiary intrusive and metamorphic rocks exposed in the Wallowa Mountains and southern Blue Mountains, and basalts of the Miocene Columbia River Basalt Group exposed or shallowly buried...
Seasonal median daily water depths for study wetlands in the Tamarac National Wildlife Refuge, the St. Croix National Scenic Riverway, the North Temperate Lakes Long-term Ecological Research area, and the Upper Mississippi River study area from 2013-2018 Seasonal median daily water depths for study wetlands in the Tamarac National Wildlife Refuge, the St. Croix National Scenic Riverway, the North Temperate Lakes Long-term Ecological Research area, and the Upper Mississippi River study area from 2013-2018
To relate water levels in these individual wetlands to precipitation and amphibian calling activity
Mineralogic, grain-size, biologic, and stable isotopic analyses of core TOPGUN-SODA10 2A-K from Big Soda Lake, Nevada, USA Mineralogic, grain-size, biologic, and stable isotopic analyses of core TOPGUN-SODA10 2A-K from Big Soda Lake, Nevada, USA
These data were collected from the TOPGUN-SODA10 2AK core collected in 2010 by LacCore (University of Minnesota), the USGS. and the University of California (U.C.) Berkeley. The 8.9 meter length core had stable isotopes of oxygen and carbon sampled every 10 millimeters or so, and diatoms samples at every 50 millimeters to 200 millimeters depending on the depth in the core. mineralogic...
Annual Herbaceous Cover across Rangelands of the Sagebrush Biome Annual Herbaceous Cover across Rangelands of the Sagebrush Biome
Data is available on https://chohnz.users.earthengine.app/view/wga-product-comparison-means Cheatgrass (Bromus tectorum) and other invasive annual grasses represent one of the single largest threats to the health and resilience of western rangelands. To address this challenge, the Western Governors Association (WGA)-appointed Western Invasive Species Council convened a cheatgrass working...
Electron microprobe analyses of feldspars and petrographic, geochemical, and geochronologic data from the Hawkeye Granite Gneiss and Lyon Mountain Granite Gneiss in the Adirondacks of New York (ver. 2.0, May 2023) Electron microprobe analyses of feldspars and petrographic, geochemical, and geochronologic data from the Hawkeye Granite Gneiss and Lyon Mountain Granite Gneiss in the Adirondacks of New York (ver. 2.0, May 2023)
Iron oxide-apatite (IOA) deposits of the Adirondack Mountains of New York locally contain elevated REE concentrations (e.g. Taylor and others, 2019). Critical to evaluating resource potential is understanding the genesis of the IOA deposits that host the REE-rich minerals. As part of this effort, the U.S. Geological Survey (USGS) is conducting bedrock geologic mapping, geochronology...
usSEABED: Offshore surficial-sediment database for samples collected within the United States Exclusive Economic Zone usSEABED: Offshore surficial-sediment database for samples collected within the United States Exclusive Economic Zone
This usSEABED database contains six point coverages of known sediment samples, inspections, and probes from the usSEABED data collection for samples collected within the United States Exclusive Economic Zone, integrated using the software system dbSEABED. Textural, statistical, geochemical, geophysical, dominant component, and color data are available as three files, which represent the...
Geochemical, mineralogical, and grain-size data for in-situ solid materials and suspended sediment at Malakoff Diggins State Historic Park, Nevada County, California Geochemical, mineralogical, and grain-size data for in-situ solid materials and suspended sediment at Malakoff Diggins State Historic Park, Nevada County, California
This dataset includes data for in-situ solid materials and suspended sediments from surface-water samples, as well as surface-water chemistry from samples collected during storm events at Malakoff Diggins State Historic Park, Nevada County, California. In-situ solid samples were collected during 2015 along six vertical transects along the cliff walls of the mine pit. Surface-water...
Estimated habitat suitability for the American burying beetle using land cover classes in the Southern Plains (ver. 1.1, June 2020) Estimated habitat suitability for the American burying beetle using land cover classes in the Southern Plains (ver. 1.1, June 2020)
Potentially suitable habitat for the American burying beetle (Nicrophorus americanus) was identified within their Southern Plains range. The American burying beetle (ABB) is listed as endangered under the Endangered Species Act, but in 2019 the U.S. Fish and Wildlife Service proposed to reclassify this species as threatened. We applied a deductive model for the ABB that identified...
Nesting Habitat and Nest Survival Data for American (Pluvialis dominica) and Pacific (P. fulva) Golden-Plovers on the Seward Peninsula, Alaska, 2012-2013 Nesting Habitat and Nest Survival Data for American (Pluvialis dominica) and Pacific (P. fulva) Golden-Plovers on the Seward Peninsula, Alaska, 2012-2013
This data set contains information (in two tables) on nesting habitat and nest survival for American (Pluvialis dominica) and Pacific (P. fulva) Golden-Plovers monitored at seven study sites across an elevational gradient (28-416 m) on the Seward Peninsula in northwestern Alaska during the summers of 2012 and 2013. We used principal components analysis to reduce habitat measurements into...
