The U.S. Geological Survey (USGS), in cooperation with the Harris-Galveston Subsidence District and Fort Bend Subsidence District, constructed a finite-difference numerical groundwater-flow model of the northern Gulf Coast aquifer region for 1897 through 2018 using MODFLOW 6 with the Newton formulation solver to simulate groundwater flow and land-surface subsidence. Model parameter estimation and

Ken Pierce was a Research Geologist with the U.S. Geological Survey for over 55 years and authored numerous scientific papers, geologic maps, and field trip guides. This data release contains digital scans of 44 field notebooks authored by Ken Pierce or his collaborators. Information contained in these notebooks provided much of the underpinning of Ken Pierce's research on the glacial and geomorph

Samples of vein-type magmatic-steam alunite were collected over several field seasons from five mines and prospects (L&N, Mt. Edna, Christmas, upper Mineral Products, and Close In) in the Alunite Ridge and Deer Trail Mountain area, Marysvale, Utah, as well as a sample from the Deer Trail mine workings from which sericite was separated. The magmatic-steam alunite and sericite were analyzed by the 4

These data were compiled for use by researchers and land managers in studies of post-grazing change in Capitol Reef National Park. The data were initially used for and are associated with the McNellis et al., 2023 (see Larger Work Citation). Objective(s) of our study were to study landscape change (specifically plant cover measured through remote sensing) through time in Capitol Reef National Park

These data were compiled from six automated weather stations that together provide several points in the meteorological record across a latitudinal and elevational gradient in southeastern Utah. Recorded data from these weather stations are associated with several different studies. Meteorological data are important for quantifying short term weather events as well as longer term climate trends. S

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 section of

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 representing unconsol

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 format: 1

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. Our result

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 under the PM

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.
