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

Michael D Pace, Burke J Minsley, Craig W Moulton & James Reitman
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...

Supporting groundwater salinity data used for salinity mapping adjacent to the Lost Hills and Belridge oil fields, Kern County, California

Lyndsay B Ball
This dataset contains summarized historical groundwater salinity observations from wells near the Lost Hills and Belridge oil fields in the southwestern San Joaquin Valley, Kern County, California. Total dissolved solids (TDS) concentration, electrical fluid conductivity (EC), and well construction information were aggregated from public data sources and local water management agencies.

Kristina Montoya-Aiona, P. Marcos Gorresen, Karen N Courtot & Julia P.S. Hoeh
The Hawaiian hoary bat (Lasiurus cinereus semotus), a federally and state listed endangered subspecies, is the only extant native terrestrial mammal in the Hawaiian archipelago. It is an insectivorous, solitary and foliage-roosting species that generally roosts alone or in mother-pup family groups. A total of 58 bats (17 female; 41 male; 56 adult; 2 juvenile) were captured at multiple locations on the east side of Hawaii Island from May 2018 through September 2019. Radio transmitters...

Tungsten Deposits in the United States

Nick A. Karl, Thomas R. Carroll, Meredith H. Burger, Germà Schmeda, Tyler A Reyes & Keith R Long
Tungsten deposits have been mined in the United States since the late 19th century, but there has been minimal production of tungsten from mines in the United States since price crashes in the 1980's. Tungsten is necessary for strategic, consumer, and commercial applications. Due to its strength, hardness, high melting and boiling points, tungsten is used in wear-resistant applications, specialty steel and alloys, and electrical and chemical products. In 2017, the United States had a...
