Data

This data set contains individual adult bighorn sheep entry and exit/censor times for 3 disease states and 2 mortality states: susceptible, infected and recovered and disease-caused death and non-disease related death. These times are used in a time-to-event analysis that employs a mixture model approach to characterize transition rates between states.

Patrick Bayou, a section of the Houston Ship Channel near Deer Park, Texas, has accumulated permitted industrial wastewater discharges, municipal wastewater treatment plant effluent, and stormwater runoff from adjacent industrial facilities and nearby urban and residential areas. These discharges are suspected to be the primary sources of the sediment contamination in the Patrick Bayou...

The U.S. Geological Survey developed two steady-state finite-difference regional groundwater-flow models using the MODFLOW-NWT computer code. These models simulate flow in the area of historical iron mining on and around the portion of the Mesabi Iron Range that is in the St. Louis River basin in northeastern Minnesota. The models are composed of 8 layers each; the upper four...

This database contains the United States salient statistics and world production statistics for over 88 nonfuel mineral commodities. Salient statistics for the United States includes items such as production, imports, exports, price, stocks, apparent consumption, and/or net import reliance for nonfuel mineral commodities. The database contains two separate table files (entities) in CSV...

Here we report ultra-high resolution infrared mapping of organic matter functional group distribution in Tasmanites (algal microfossils) from the Upper Devonian Ohio Shale using optical photothermal infrared spectroscopy (O-PTIR). O-PTIR is capable of rapidly measuring the vibrational response of samples in situ with ~500-nm spatial resolution, well below the infrared diffraction limit...

This data set consists of monthly long-term mean temperature data (degrees C) for the last glacial maximum (21 ka) downscaled to a 10-km grid of North America. The 10-km data were derived using simulated temperature data from 10 general circulation models (GCMs; CCSM4, CNRM-CM5, COSMOS-ASO, FGOALS-g2, GISS-E2-R, IPSL-CM5A-LR, MIROC-ESM, MPI-ESM-P-OA, MPI-ESM-P-OAC, and MRI-CGCM3) run...

An inventory (enumeration and taxonomic identification) of diet items consumed by wild-caught black carp, based on the examination of gut contents from fish that were collected in the lower Mississippi River drainage of the U.S.

An inventory (enumeration and taxonomic identification) of diet items consumed by wild-caught larval pallid sturgeon and larval shovelnose sturgeon, based on the examination of gut contents from fish that were collected in the Upper Missouri River drainage of the U.S.

The geochemical data included here were generated as part of the Earth Mapping Resources Initiative (Earth MRI), which was developed by the U.S. Geological Survey (USGS) in response to a Federal directive calling on various Federal agencies to address potential vulnerabilities in the Nation's supply of critical mineral resources. Earth MRI is a partnership between the USGS, State...

In the United States and globally, contaminant exposure in unregulated private-well point-of-use (POU) tapwater (TW) is a recognized public health data gap and an obstacle to both risk management and homeowner decision making. To help address the lack of data on broad contaminant exposures in private-well TW from hydrologically vulnerable (alluvial or karst) aquifers in agriculturally...

Data describe results of a set of laboratory experiments using a previously described quantitative thiaminase I activity assay to test the thiaminase activity of whole zebrafish homogenates. Parameters described include the thiaminase activity data, dilution factors, incubation time, and tissue weight assayed. Experiments were conducted at the USGS Columbia Environmental Research Center...

Stream water chemistry and benthic macroinvertebrate data collected in the North Fork of Clear Creek and Clear Creek, CO, USA before and after the diversion and treatment of acid mine drainage by a high-density sludge lime process water treatment plant. Stream water chemistry and benthic macroinvertebrate samples were collected from November 2011 through October 2019 at 6 sites located...
