Lost Hills Belridge 3D visual readme file

Description

This 3D visual displays data that can be found in Gillespie and others (2019a). This data release was updated in June 2022 to correct some erroneous data points found in the “geologic_markers.csv” file. This file was replaced with “geologic_markers (ver 2.1).xlsx”, and it contains the depths of various geologic layers and the base of the <10,000 mg/L water in the Lost Hills/Belridge area. One well (02975040) was added to “geophysical_log_analysis (ver 2.1).xlsx”. Please see the related manuscript for details (Gillespie and others, 2019b). The z-axis in the visual is scaled by 0.35.

The changes from version 2 to version 3 were:

02937672: Amnicola base from 1,310 ft to 1,348 ft.
02935522: Removed well.
02909463: Removed well.
03034569: Changed longitude from -119.717958 to -119.7356734.
02929577: Changed Tulare base from 2,074 ft to 1,717 ft.
02936507: Removed the middle Tulare clay pick.
