Beach topography of the Columbia River littoral cell, Washington and Oregon, 2015

This portion of the USGS data release presents topography data collected during surveys performed in the Columbia River littoral cell, Washington and Oregon, in 2015 (USGS Field Activity Number 2015-647-FA). Topographic profiles were collected by walking along survey lines with global navigation satellite system (GNSS) receivers mounted on backpacks. Prior to data collection, vertical distances between the GNSS antennas and the ground were measured using a tape measure. Hand-held data collectors were used to log raw data and display navigational information allowing surveyors to navigate survey lines spaced at 100- to 1000-m intervals along the beach. Profiles were surveyed from the landward edge of the study area (either the base of a bluff, engineering structure, or just landward of the primary dune) over the beach foreshore, to wading depth on the same series of transects as nearshore bathymetric surveys that were conducted during the same time period. Additional topographic data were collected between survey lines in some areas with an all-terrain vehicle (ATV) equipped with a GNSS receiver to constrain the elevations and alongshore extent of major morphological features. Positioning data from the survey platforms were referenced to a GNSS base station with known horizontal and vertical coordinates relative to the North American Datum of 1983. Differential corrections from the GNSS base stations to the survey platforms were either applied in real-time with a VHF radio link, or post-processed using Trimble Business Center software. Orthometric elevations relative to the NAVD88 vertical datum were computed using National Geodetic Survey Geoid12a offsets. The average estimated vertical uncertainty of the topographic measurements is 4 cm. The final point data are provided in comma-separated text format and are projected in Cartesian coordinates using the Washington State Plane South, meters coordinate system.

Depth to Groundwater Measured from Wells Completed in the Chicot, Evangeline, and Jasper Aquifers, Houston-Galveston Region, Texas, 2019

This dataset documents the depth to groundwater measured in wells screened in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas for 2019. The U.S. Geological Survey prepared this dataset in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District. This dataset was created to provide resource managers, public officials, researchers, and the general public with ready access to information regarding depths to groundwater in the region. All of the data in this dataset were collected from December 2018 through March 2019 and are stored in the National Water Information System (NWIS), a publicly available, searchable, online database of water information (http://dx.doi.org/10.5066/F7P55KJN).

Local Species-Environment Relationships

This dataset provides the environmental explanatory variables used to explore spatial patterns in species-environment relationships in Gopherus agassizii and Gopherus morafkai across the subregion encompassing the genetic sampling locations used by Edwards et al. (2015). This region offered an opportunity to explore habitat selection across the ecotone between the Mojave and Sonoran deserts and the secondary contact zone between G. agassizii and G. morafkai, and is referred to as the focal study area. The raster layers contained here accompany the manuscript Inman et al. 2019 and were used to identify multivariate clusters and map them back to geographic space.

Electrical Resistivity Tomography (ERT) Surveys at the Callahan Mine Superfund Site in Brooksville, Maine: May 2017

On May 10, 2017 an electrical resistivity tomography (ERT) profile was collected on the land along the gravel path between the water and the slime impoundment associated with the former mine activities.  A total of 56 electrodes, spaced 1 m apart, extended along the base of the slope. Electrode 1 was near monitoring well MW-701 and electrode 56 was near MW-702. 
In the ERT measurement current is injected through two current electrodes and voltage is measured sequentially across multiple pairs of potential electrodes, which is used to determine the apparent resistivity of the subsurface. In addition, induced polarization (IP) was measured to assess the presence of chargeable layers. Two surveys were collected in dipole-dipole and combined Wenner-Schlumberger configurations. Results were also combined into a merged dataset.  ERT resistivity and IP surveys can be inverted to obtain resistivity profiles that can be interpreted for subsurface layers. This data release provides the raw ERT data.

Continuous Seismic Profiling with a Dual-Frequency Echo Sounder (CSP-DSO) at Callahan Mine Site: May 2017

In May 2017 a dual-frequency echo sounder was used in Goose Pond at the former Callahan Mine site to obtain seismic profiles in very shallow water. The method uses two fixed transducers mounted in the same housing. One transducer was 24 kiloHertz (kHz) and the other was 200 kHz. The CSP-DSO data were collected concurrently with continuous resistivity profiling data, and the water bottom was determined with the 200 kHz transducer.  The seismic traces on the low frequency transducer were used to analyze the subbottom materials.  In some places the signal penetrated the subsurface, but in many places the signal reflected off of a shallow subsurface layer.   The data quality was not as good as the swept frequency (chirp) CSP data, but the dual-frequency sounder could be used in much shallower water than the chirp system.

Potential suitable habitat for Beaver Dam breadroot (Pediomelum castoreum) in the California desert

Here we present the map of potential suitable habitat for Beaver Dam breadroot (Pediomelum castoreum). The data indicate both how many models predicted each location to be potentially suitable for the species and the average standardized habitat suitability score for each location.Data are presented at a spatial resolution of 10 m pixels, which was required to harmonize the original model inputs. However, maps of suitable habitat should be used at a resolution no smaller than 360 m (i.e., 36 pixels x 36 pixels), which corresponds with the resolution of the coarsest model input. These data are intended to be used only to target future plant surveys in areas where new occurrences are most likely to benefit future habitat modelling efforts. Complete methods and other additional information are provided in the article associated with this data release (Reese and others, 2019).

Regional climate modeling and land use change data for the Eastern United States and Cuba (1650, 1850, 1920, and 1992)

Natural and anthropogenic land use are integral to the climate system and land use change is both a driver of, and responder to changes in climate.  The potential for land use and land use change to affect global and regional climate plays a central role in the development of scenarios for greenhouse gas emissions that are used in climate model simulations.  Climate models are well suited for exploring interactions with land use and land use change and a number of global and regional modeling studies have investigated past, present, and potential future climate responses induced by land use change.  We assess climate responses to the land use change in the Eastern United States and Cuba during four epochs (1650, 1850, 1920, and 1992) with ensemble simulations conducted with the RegCM4 regional climate model. The 8-member ensembles for each land use epoch were driven by perturbing 1990-2002 atmospheric boundary conditions derived from the National Center for Environmental Prediction (NCEP) global reanalysis. The applied version of the model includes the Biosphere Atmosphere Transfer Scheme (BATS1e) surface physics package. We derived the land use data sets by harmonizing a previous reconstruction with updated observations and modeled potential vegetation.

Electrical Resistivity Tomography (ERT) Surveys Collected in Fredericktown, Missouri, June 2018

In June 2018, U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency (EPA) collected geophysical measurements to help evaluate the suitability of a proposed landfill site for disposing mine-waste materials in Fredericktown, MO. Two survey profiles were collected, each including dipole-dipole and Wenner-Schlumberger configurations. For each survey a total of 28 electrodes spaced 1.0 meter (m) apart were used. During the ERT measurement, current is injected through two current electrodes and voltage is measured sequentially across multiple pairs of potential electrodes; the known current and the measured voltages are used to determine the apparent resistivity of the subsurface. Inverse modeling of ERT survey results provide profiles of resistivity that can be interpreted for subsurface layers. This data release provides the raw ERT data and output from inversion.

Model Archive Summary for Suspended Sediment, Acoustic Sediment Surrogate Model 2.0, USGS gage number 13342500, Clearwater River at Spalding, Idaho

From 2008 to 2012, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, Walla Walla District, developed an acoustic backscatter surrogate (model 1.0) for estimating real-time suspended-sediment concentration and loads at Clearwater River at Spalding, ID (USGS ID: 13342500) using a horizontally-mounted 3000kHz acoustic Doppler velocity meter (ADVM). This study is a continuation of the 2008 to 2012 acoustic backscatter surrogate study using samples collected since 2015 to validate the continued use of model 1.0. Sample data collected in 2015 to 2018 show a deviation from model 1.0 when backscatter data from the ADVM, after correction for acoustic losses, is greater than 65.7 decibels. The model archive summary documents acoustic backscatter surrogate model 2.0 for the real-time calculation of suspended-sediment concentration at Clearwater River at Spalding, ID (USGS ID: 13342500). Model 2.0 is in effect from March 24, 2015 to September 30, 2019 (end of the study). The methods used in the study follow U.S. Geological Survey protocols as referenced in relevant Office of Surface Water/Office of Water Quality Technical Memoranda and U.S. Geological Survey Techniques and Methods reports.

Forward Looking Infrared (FLIR) Imaging in Fredericktown, Missouri, June 2018

In June 2018, U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency (EPA) collected geophysical measurements to help evaluate the suitability of a proposed landfill site for disposing mine-waste materials in Fredericktown, MO.   Forward Looking Infrared (FLIR) images were acquired at two locations to characterize the temperature of the water and the embankment along the shoreline of City Lake to evaluate potential groundwater discharge locations. The images were collected in the evening dusk to avoid reflections off the water surface while pointing at the shoreline. Visual true-color photographs and FLIR thermal images were collocated to help identify the location of potential thermal anomalies that might indicate groundwater discharge into the lake. The visual images can be used to help interpret the thermal images that might show obstructions or reflections from the vegetation.
