Streambed sediment data for Missouri and Niobrara Rivers, Nebraska and South Dakota, 2015

Deltaic sand deposits at the head of Lewis and Clark Lake, Nebraska-South Dakota were investigated for suitability for use as a proppant feedstock resource in unconventional oil or gas production. The physical characteristics of the deposits are described in four supplemental data sets in varied file formats. First, for the direct-push cores collected at four sandbar complexes in the Missouri River delta, detailed descriptions of core lithology and texture are provided in Comma Separated Values (CSV) file format. Second, apparent resistivity results from capacitively coupled (CC) resistivity profiles collected along surface-geophysical reconnaissance lines are displayed using standardized color ramps and vertically exaggerated scales.
