Summary
This section of the data release includes core log and spectrophotometry data in the format of a comma-separated value (CSV) file (2018LakePowellCoring_CoreLogData.csv). It is Part 3 (of four) in this data release and provides geophysical core logs at 0.5-cm intervals from a Multi-Sensor Core Logger and Konica Minolta spectrophotometer. This CSV includes the depth in section and hole for each logged point, p-wave amplitude and velocity, gamma density, loop- and point-sensor magnetic susceptibility, electrical resistivity, colorspace data, and measured reflectance wavelengths. Drillhole information, such as location and total recovery, are outlined in “Part 1 – Drillhole information from the 2018 coring project in Lake Powell, Utah” [...]

Each drillhole comprises multiple cores which are outlined in “Part 2 – Core and core section information from the 2018 coring project in Lake Powell, Utah” (2018LakePowellCoring_CoreSectionInfo.csv) of this data release. Corresponding core images can be found in “Part 4 – Photographs of sediment cores collected in 2018 from Lake Powell, Utah” (2018LakePowellCoring_CorePhotos.zip).

Purpose
Cores were collected to characterize the sediment that has deposited in Lake Powell and determine the presence, if measurable, of metals associated with the 2015 Gold King Mine release in the San Juan River delta. Data further provides empirical evidence for volumetric studies in sedimentation and storage capacity.
