Data and Tools

Science Datasets

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.

Electron microprobe analyses of feldspars from the Hawkeye and Lyon Mountain Granite Gneisses in the Adirondacks of New York.

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, geochro

Argon data for Southern Patagonian Andes

This dataset accompanies planned publication 'Detrital record of the Late Oligocene – Early Miocene mafic volcanic arc in the Southern Patagonian Andes (~51°S) from single-clast geochronology and trace element geochemistry'. The Ar/Ar data is for samples that record the detrital sedimentary record of the basin. The geochronology provides time constraints for the sedimenta

Molecular and morphological data to resolve species boundaries in the critically imperiled freshwater mussel species, Fusconaia mitchelli

We generated multilocus DNA sequence data and traditional morphometric measurements to evaluate species boundaries in Fusconaia mitchelli. We sequenced three loci: the protein-coding mitochondrial DNA genes cytochrome oxidase subunit 1 and NADH dehydrogenase 1, and the nuclear ribosomal internal transcribed spacer 1. We also took three measurements, maximum length, maximum width, and ma

2020 Known and Probable Grizzly Bear Mortalities in the Greater Yellowstone Ecosystem

Identifying the locations and causes of grizzly bear mortality is another key component in understanding the dynamics of this population. Over 80% of all documented bear mortalities are human-caused. Tracking human-caused bear deaths helps define patterns and trends that can direct management programs designed to reduce bear mortality.

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 me

Investigating the effects of broad ion beam milling to sedimentary organic matter

To test if reflectance increases to sedimentary organic matter (vitrinite) caused by broad ion beam (BIB) milling were related to molecular aromatization and condensation, we used Raman and Fourier transform infrared (FTIR) spectroscopies to evaluate potential compositional changes in the same vitrinite locations pre- and post-BIB milling. The same locations also were examined by at

National Assessment of Hurricane-Induced Coastal Erosion Hazards: 2020 Update

This dataset contains information on the probabilities of hurricane-induced erosion (collision, inundation and overwash) for each 1-kilometer (km) section of the United States [Gulf of Mexico and Atlantic] coast for category 1-5 hurricanes. The analysis is based on a storm-impact scaling model that uses observations of beach morphology combined with sophisticated hydrodynamic models

Oceanographic measurements collected in the Stillaguamish River Delta, Port Susan, Washington, USA from March 2014 to July 2015

This data release includes time-series and discrete measurements made within two breaches constructed in a former flood-control levee of a restored agricultural area in Port Susan, Washington. An area of approximately 61 ha near the mouth of the Stillaguamish River was reconnected to tidal flow via levee breaches as part of a larger restoration effort that took place in 2012. These...

Discharge measurements collected in the Stillaguamish River Delta, Port Susan, Washington, USA in March, April, and May 2014

Tidal water discharge within two breaches constructed in a former flood-control levee of a restored agricultural area in Port Susan, Washington, was measured repeatedly during several tidal cycles. Measurements were made on March 27, 2014, April 16, 2014, May 18, 2014, and May 29, 2014 at breach PSB1, and on May 29, 2014 at breach PSB2. These data were collected using a boat

Oceanographic time-series measurements collected in the Stillaguamish River Delta, Port Susan, Washington, USA from March 2014 to July 2015

Water level, flow velocity, temperature, salinity, and turbidity were measured in a breach constructed in a flood-protection levee surrounding a restored former agricultural area in Port Susan, Washington, USA, near the mouth of the Stillaguamish River. Data were collected in a breach known as PSB1 at 15-minute intervals from March 21, 2014 to July 1, 2015 using a SonTek Argonau

Geophysical Data Collected in the Cedar River Floodplain, Cedar Rapids, Iowa, 2015-2017

A suite of geophysical methods was used along the Cedar River in Cedar Rapids, Iowa to support the hydrogeologic characterization of the alluvial aquifer associated with the river and to assess the area for suitability for larger-scale airborne geophysics. The aquifer is comprised of sand and gravel, interbedded with finer sediments, and underlain by carbonate-dominated bedrock. The aquife...
