Borehole nuclear magnetic resonance (NMR) logging 2016-2017

Title
Borehole nuclear magnetic resonance (NMR) logging 2016-2017
Abstract
This dataset contains measurements made with the Vista Clara (Mukilteo, WA) Javelin family of borehole nuclear magnetic resonance (NMR) logging tools. The Javelin Surface Station was used for all measurements, and probes JP175B, JP175D, and JP350 were used depending on the available borehole. Data were collected between January of 2016 and August 2017 at sites across Wyoming, Colorado, New Jersey, Jemez Critical Zone Observatory, Calhoun Critical Zone Observatory, among other sites. All raw data are provided, as well as basic processing using inversion and interpretation supplied with the logging NMR instrument also produced by Vista Clara. Spatial and temporal information are provided for all datasets, as well as all instrument setup and inversion parameters.
