Magnetic Resonance Sounding Survey Data Collected in the North Platte, Twin Platte, and South Platte Natural Resource Districts, Western Nebraska, Fall 2012.

摘要

This report is a release of digital data and associated survey descriptions from a series ofmagnetic resonance soundings (MRS, also known as surface nuclear magnetic resonance) that wasconducted during October and November of 2012 in areas of western Nebraska as part of a cooperativehydrologic study by the North Platte Natural Resource District (NRD), South Platte NRD, Twin PlatteNRD, the Nebraska Environmental Trust, and the U.S. Geological Survey (USGS). The objective of thestudy was to delineate the base-of-aquifer and refine the understanding of the hydrologic properties inthe aquifer system. The MRS technique non-invasively measures water content in the subsurface,which makes it a useful tool for hydrologic investigations in the near surface (up to depths ofapproximately 150 meters). In total, 14 MRS production-level soundings were acquired by the USGSover an area of approximately 10,600 square kilometers. The data are presented here in digital format,along with acquisition information, survey and site descriptions, and metadata.
