Ground-based electromagnetic survey, Shellmound, Mississippi, October 2018

Shallow soil characteristics were mapped near Shellmound, Mississippi, using the DualEM 421 electromagnetic sensor in October 2018. Data were acquired by towing the DualEM sensor on a wheeled cart behind an all-terrain vehicle (ATV), with the sensor at a height of 0.432 meters (m) above the ground surface. Approximately 175 line-kilometers of data were acquired over an area of nearly four square-kilometers, with 25 m separation between survey lines. Data were manually edited for noise sources such as powerlines or other buried structures and averaged to regular output soundings every 5 m along survey lines. The processed data were inverted to recover models of electrical resistivity structure as a function of depth at each sounding location using a spatially constrained inversion. This data release contains the raw and processed data, as well as inverted resistivity models. Model results show typical depth of investigation from about 4 – 6 m, with spatial variability in mapped electrical resistivity characteristic of fluvial deposition of sediments in channels and scroll bar features adjacent to the Tallahatchie River and nearby abandoned meander channels.

Brazoria NWR Prairie Resilience Data

In 1996, 400 tree-centered plots were established by first randomly choosing x- and y- coordinates from an imaginary grid overlaying the study area. Each random point was also randomly assigned a tree-size category from a pre-determined sampling scheme. The scheme was to include 20 trees from each of 5 size categories. Size/height categories were: less than 0.1m, 0.1-1m, 1-2m, 2-3m, and greater than 3.0m. To avoid excessive aggregation of samples, no more than 5 trees in a size class could be chosen within a 100-meter sub-area of the sampling grid. The nearest tree to each random point that met the pre-determined size requirement was identified and marked with a permanent aluminum tag. For the size category less than 0.1m tall, field-collected seedlings were transplanted into plots. Transplanted seedlings were monitored and watered for 2 months prior to pre-burn measurements. Pre-burn measurements included: maximum tree height (using telescoping measuring poles), non-destructive estimation of total community biomass (Whitbeck and Grace 2006), and herbaceous community species composition. Sub-areas within the study area were randomly chosen for burning in either the growing or dormant season. Dormant-season burns were conducted in January 1997 and growing-season burns in August 1997. Prescribed burns were conducted by USFWS fire crews according to normal prescriptions for the area. Plots were resampled immediately following fire to determine burn completeness of plots, as well as for general observations. Effectiveness of fire treatments were assessed at the end of the subsequent growing season (September 1998). At that time, maximum height of trees was remeasured, along with general community characteristics.

Petroleum well data used for preliminary regional groundwater salinity mapping near selected oil fields in central and southern California

This digital dataset is comprised of two separate data files that contain total dissolved solids, well construction, and well identifying information for 1,131 petroleum wells used to map salinity in and around 31 southern and central California oil fields. Salinity mapping was done for 27 fields located in the southern San Joaquin Valley of Kern County (North Belridge, South Belridge, Canfield Ranch, North Coles Levee, South Coles Levee, Cymric, Edison, Elk Hills, Fruitvale, Greeley, Jasmin, Kern Bluff, Kern Front, Kern River, Lost Hills, Mount Poso, Mountain View, Poso Creek, Rio Bravo, Rosedale, Rosedale Ranch, Round Mountain, San Emidio Nose, Tejon, Ten Section, Wheeler Ridge, and Yowlumne), 3 fields in the Los Angeles (LA) Basin of Los Angeles County (Montebello, Santa Fe Springs, and Wilmington), and 1 field in the central coast area of Santa Barbara and San Luis Obispo Counties (Santa Maria Valley). Only petroleum wells that were located within the administrative boundaries of these 31 fields were used for salinity mapping. The dataset includes total dissolved solids (TDS) analyses from 1930 to 2015. TDS data for each well varies from a single analysis to multiple analyses for different sample dates and (or) collected from different depths within the same well. For wells having multiple analyses TDS represents the median value. There are 159 wells in the dataset each having 2-4 TDS analyses, including 15 wells having TDS values from different depths.  
This dataset also includes ancillary data in the form of top perforation depth, land-surface elevation at the well head, and well location and identifier information. For petroleum wells missing top perforation depth (3 percent), the median top perforation depth for all wells within the field having top of perforation depth is provided as an approximation for the purpose of vertical plotting. 
Summary data about each well used for salinity mapping is contained in the file called Petroleum_Wells_Summary_Data. Detailed information about all individual TDS values including those used for determining median TDS values, are contained in the file called Petroleum_Wells_All_Data.

Biophysical assessment for indemnity selection of federal lands in Colorado: Potential species of management concern

The "Biophysical assessment for indemnity selection of federal lands in Colorado: Potential species of management concern" dataset summarizes the species (federally threatened or endangered species, Colorado Bureau of Land Management (BLM) sensitive species, U.S. Fish and Wildlife Service Birds of Conservation Concern, and Colorado Parks and Wildlife big game species) that have the potential for occurrence within 89 Indemnity Units. The Indemnity Units are federal lands, currently managed by the BLM, under consideration for transfer to the State of Colorado in compensation for federal lands not available for transfer at the time of statehood. We compiled information on documented occurrences, habitat (seasonal, specialized, and general), and overall ranges for all 179 species or subspecies identified by the BLM as species of management concern in Colorado. The compiled information was used to determine the species that have the potential for occurrence on each Indemnity Unit. The results indicated that 72 species had documented occurrences or habitat within at least one Indemnity Unit. This dataset includes the data type used for each of the 72 species to determine the potential for occurrence in each Indemnity Unit. The dataset format is a comma-separated values (CSV) text file, which can be joined with the "Indemnity Unit locations" dataset (via the IU_Code) or used independently. Additional information on data sources and processing for this dataset is provided in the SupplementalMethods.pdf included with this data release.

2008 North Carolina and Virginia NOAA/NGS Lidar-Derived Dune Crest, Toe and Shoreline

The Storm-Induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Lidar-derived beach morphologic features such as dune crest, toe and shoreline help define the vulnerability of the beach to storm impacts. This dataset defines the elevation and position of the seaward-most dune crest and toe and the mean high water shoreline derived from the 2008 Atlantic Coast National Oceanic and Atmospheric Administration (NOAA) National Geodetic Survey (NGS) lidar survey. Beach width is included and is defined as the distance between the dune toe and shoreline along a cross-shore profile. The beach slope is calculated using this beach width and the elevation of the shoreline and dune toe.

2017 seismic imaging of the West Napa Fault Zone, St. Helena, California

In April 2017, the U.S. Geological Survey acquired high resolution P- and S-wave seismic data across the suspected trace of the West Napa Fault zone in St. Helena, California. We acquired seismic reflection, refraction, and guided-wave data along a 215-m-long profile across the expected trend of the West Napa Fault zone.  To acquire the reflection and refraction data, we co-located shots and geophones, spaced every 2 m along the profile.  We used 109 SercelTM L40A P-wave (40-Hz vertical-component) geophones with a sensitivity of 22.34 volts/meter/second to record 108 P-wave shots, and 109 SercelTM L28-LBH S-wave (4.5-Hz horizontal-component) geophones with a sensitivity of 31.3 volts/meter/second to record 108 S-wave shots. We generated P-wave data using one of two active sources depending on site accessibility: a 226-kg accelerated weight drop (AWD) and a 3.5-kg sledgehammer and steel plate combination. S-wave sources were generated by horizontally striking an aluminum block with a 3.5-kg sledgehammer. We acquired fault zone guided wave data by generating P- (AWD) and S-wave (angle AWD) energy approximately 225 m north of the P- and S-wave recording arrays. All data were recorded using two 60-channel Geometrics Stratavisor NX-60TM seismographs with a 24-bit analog-to-digital converter with a roll-along descaling factor (Subcommittee of the SEG Engineering and Groundwater Geophysics Committee, 1990); the seismographs were connected to the P- and S-wave geophones via refraction cables. Each shot was recorded for two seconds, with data recording starting 100 ms before the actual time of the shot.  Data were recorded at a sampling rate of 0.5 ms, or 2000 samples per second. This report provides the metadata needed to utilize the seismic data.
