GEOL 420 Data Library

This webpage is the Galactic Portal to the One Source of Truth GEOL 420 Data Library.

• It is organized below by either the GEOL 420 term (e.g. Fall 2026, Fall 2025, etc.) or other project names from which we use data.

• Links take you to a file-server for the directory. Near the top-right of the page switch to large list view for easiest reading.

• From each directory you can then select and download what you need. Reorganize/rename the files as you please. If you made a mistake, just return here to start over.

Dog Leg

2026-09-03 (Thursday): Wenner VES

• The field notes are just the data and minimal information about the VES survey for reference - not the complete field notes one should be taking.

2026-07-17 (Thursday): 2D ERT

Two array styles collected on the same profile. This profile is very nearly the same profile as the 2026-09-03 Wenner VES data. The two array styles are useful for comparison to one another for thinking about array resolution, and to compare to the Wenner VES.

• Dipole Gradient Array "STG" file DOGLEG2D.stg for inversion, and full DOGLEG2D.zip SuperSting download.

• Dipole-Dipole Array "STG" file 4.stg for inversion, and full 4.zip SuperSting download.

• Field Notes: Page 1 and Page 2
