Electrical Resistivity Tomography Inverted Models; Alaska, 2015

Fire can be a significant driver of permafrost change in boreal landscapes, altering the availability of soil carbon and nutrients that have important implications for future climate and ecological succession. However, not all landscapes are equally susceptible to fire-induced change. As fire frequency is expected to increase in the high latitudes, methods to understand the vulnerability and resilience of different landscapes to permafrost degradation are needed. Geophysical and other field observations reveal details of both near-surface (less than 1 m) and deeper (greater than 1 m) impacts of fire on permafrost along 14 transects that span burned-unburned boundaries in different landscape settings within interior Alaska. Electrical resistivity tomography (ERT) data collected along the 14 transect were used to map the spatial distribution of permafrost across burned-unburned boundaries.

Global temperate drylands climate change vulnerability

Drylands cover 40% of the global terrestrial surface and provide important ecosystem services. While drylands as a whole are expected to increase in distribution and aridity in coming decades, temperature and precipitation forecasts vary by latitude and geographic region suggesting different trajectories for tropical, subtropical, and temperate drylands. Uncertainty in the future of tropical and subtropical drylands is well constrained, whereas soil moisture and ecological droughts, which drive vegetation productivity and composition, remain poorly understood in temperate drylands. Here we show that, over the 21st century, temperate drylands may contract by a third, primarily converting to subtropical drylands, and that deep soil layers will be increasingly dry during the growing season. These changes imply major shifts in vegetation and ecosystem service delivery. Our results illustrate the importance of appropriate drought measures and, as the first global study to focus on temperate drylands, highlight a distinct fate for these highly-populated areas.
The data are outputs from the SOILWAT ecohydrological model, which was applied in a grid over 6 temperate drylands across the globe (South America, Southern Africa, Eastern Asia, Western and Central Asia, Western Mediterranean basin, and North America.  Simulations were conducted for two time periods: 1980-2010 and 2069-2099.

Results of Hydrologic Monitoring of a Landslide-Prone Hillslope in Portland's West Hills, Oregon, 2006-2017

The West Hills of Portland, in the southern Tualatin Mountains, trend northwest along the west side of Portland, Oregon. These silt-mantled mountains receive significant wet-season precipitation and are prone to sliding during wet conditions, occasionally resulting in significant property damage or casualties. In an effort to develop a baseline for interpretive analysis of  the groundwater response to rainfall, an automated monitoring system was installed in 2006 to measure rainfall, pore-water pressure, soil suction, soil-water potential, and volumetric water content at 15-minute intervals. The data show a cyclical pattern of groundwater and moisture content levels—wet from October to May and dry between June and September. Saturated soil conditions tend to last throughout the wet season. This release presents data collected from January 10, 2006, through January 23,2017.

Surface-sediment grain-size distributions of the Elwha River delta, Washington, January 2015

This portion of the data release presents sediment grain-size data from samples collected on the Elwha River delta, Washington, in January 2015 (USGS Field Activity 2015-605-FA). Surface sediment was collected from 61 locations using a small ponar, or 'grab', sampler from the R/V Frontier in depths between about 1 and 17 m around the delta. A handheld global satellite navigation system (GNSS) receiver was used to determine the locations of sediment samples. The grain-size distributions of samples were determined using standard techniques developed by the USGS Pacific Coastal and Marine Science Center sediment lab. The grain-size data are provided in a comma-delimited spreadsheet (.csv).

Digital elevation models (DEMs) of the Elwha River delta, Washington, January 2015

This part of the data release presents a digital elevation model (DEM) derived from bathymetry and topography data of the Elwha River delta collected in January 2015. Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system to changes in sediment supply. The U.S. Geological Survey developed an integrated research program aimed at understanding the ecosystem responses following dam removal that included regular monitoring of coastal and nearshore bathymetry and topography. As part of this monitoring program, the USGS conducted a bathymetric and topographic survey in the Strait of Juan de Fuca on the Elwha River delta, Washington (USGS Field Activity Number 2015-605-FA). Bathymetry data were collected using two personal watercraft (PWCs) and a kayak, each equipped with single beam echosounders and survey-grade global navigation satellite systems (GNSS). Topography data were collected on foot with GNSS receivers mounted on backpacks. DEM surfaces were produced from all available elevation data using linear interpolation.

Reanalysis of the Medina/Diversion Lake System Water-Budget, with Estimated Recharge to Edwards Aquifer, San Antonio Area, Texas

In 2004, a hydrologic water-budget analysis was conducted and the results published in the report, Water-Budget Analysis of Medina and Diversion Lakes and the Medina/Diversion Lake System, With Estimated Recharge to the Edwards Aquifer, San Antonio Area, Texas (SIR 2004-5209)(Slattery and Miller, 2004).  This data release contains the hydrologic water-budget data used in a reanalysis of the data as well as the results of the reanalysis. The hydrologic water-budget data used was derived from selected columns of data found in table 5 of the report. The columns of selected data include the time period in which the data were collected, the number of days used to obtain the average groundwater outflow, the standard deviation of the groundwater outflow data, the average groundwater outflow, and the average Medina Lake stage. Within these columns of data are 127 water-budget periods ranging from 8 to 78 days from daily hydrologic data collected during 1955 to 1964, 1995 to 1996, and 2001 to 2002. An .R script file was constructed to perform the statistical calculations using the R programming language (R-3.3.2). The R script instructions included statistical test for a linear-linear least-squares regression analysis, a linear-linear weighted least-squares regression analysis, and a log-log weighted least-squares analysis correlating the relation of Medina Lake stage (water-surface elevation in feet [ft] above the National Geodetic Vertical Datum of 1929) to groundwater recharge (GWout) from the Medina/Diversion Lake System. The .R script output also produces text files that contain the results of the statistical analysis as well as a graphical representation of the results.

National USEPA Clean Watershed Needs Survey WWTP nutrient load data 1978 to 2012

This dataset contains tabular data for U.S. Environmental Protection Agency’s (EPA) Clean Watersheds Needs Survey (CWNS) wastewater treatment facility information. Literature-based average total nitrogen and total phosphorous concentrations
were substituted for wastewater treatment levels reported for each facility because little or no concentration data is reported in the CWNS. Concentrations were based on the treatment levels of raw, primary, secondary, and advanced. Concentration and
effluent flow-value data gaps were ‘filled in’ through simple linear assumptions, based on each facility’s responses to the survey in years bracketing the data gap or were based on an un-bracketed single year survey response. Unlike the McMahon and
others (2007) method used to complete the EPA Permit Compliance System/Integrated Compliance Information System (PCS/ICIS) dataset where data from similar facilities was used to fill the data gaps, treatment level and flow data unique to each
facility were used to complete the Clean Watershed Needs Survey dataset. [McMahon, Gerard, Tervelt, Larinda, and Donehoo, William, 2007, Methods for estimating annual wastewater nutrient loads in the southeastern United States: U.S. Geological Survey
Open-File Report 2007-1040, 81 p., https://pubs.usgs.gov/of/2007/1040/] The Clean Watershed Needs Survey data were collected by the EPA for the years 1978, 1980, 1982, 1984, 1986, 1988, 1990, 1992, 1996, 2000, 2004, 2008 and 2012, and total nitrogen
and total phosphorous loads were calculated using reported annual flows and nutrient concentration values substituted from literature for reported treatment levels from the CWNS. The long-term nutrient loads are provided as supportive information for
studies being conducted by the USGS National Water Quality Assessment (NAWQA) Project.

Groundwater Levels in the Equus Beds Aquifer near Wichita, Kansas, January 2016 (shallow raster)

This dataset is the result of measurements of groundwater levels in the Equus Beds aquifer near Wichita, Kansas, in January 2016. Potentiometric surfaces are interpolated for the shallow and deep parts of the aquifer, and rasters of the potentiometric surfaces are included in this data release. Wells were classified as being screened in the shallow or deep parts of the aquifer based on station name (some wells have a layer identifier in the station name) or, if no indication of aquifer layer was given in the station name, based on the depth of the well; wells with depths less than 80 feet below land surface were classified as shallow and wells with depths of 80 feet or deeper were classified as deep. Contours with a 5 foot interval were produced from the rasters and used to map the water levels in the aquifer. The water level measurements can be used to estimate storage-volume change in the study area between predevelopment (circa 1940) and January 2016 the historic low in 1993 and January 2016; and January 2015 and January 2016.

Uncertainty table for lidar-derived shorelines used when calculating rates in the Digital Shoreline Analysis System software for Texas west (TXwest)

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.
