## Fall 2022

### 1. Chorro Creek Dog Leg Reference Profile Geophysical Surveys
The *Chorro Creek Dog Leg Reference Profile (CCDL-RP)* is defined as an electrical resistivty profile:
- 28 electrodes at 2-meter spacing (54 meters total)
- Electrode 1 (E1) at coordinate (35.339390,-120.768990)
- From E1 to E28 follow a strike of $340^{\circ}$

Array style is variable. Other geophysical surveys (even non-electrical) that are not this exact length can then be referenced to this.
#### A. Vertical Electrical Sounding
- Tue 2022-09-27 with saltwater and tinfoil.
- Thur 2022-09-29 w/o saltwater and tinfoil.
- [A set of minimal field notes](https://cpslo-my.sharepoint.com/:b:/g/personal/jjasbins_calpoly_edu/EWzpcDXj_RBOr_IhGxvyih4BoYoAL8aA7vnb-1poVPZj_g?e=W8PlVh). Your own field notes should be more detailed. This profile is centered at the center of the "Reference Profile"
#### B. Electrical Resistivity Tomography 2D

- ==Field notes:== exactly the same as the 2022-10-04 survey (CCDL2D) just above, except used a Schlumberger Inverse array style.

#### C. Electrical Resistivity Tomography "2.9D"
- Looks like we will not collect this - but we have some previous data.

#### D. Seismic Refraction Survey

In F21 the "reference profile" is similar to the F22 version, but is 28 electrodes at 2-meter spacing (54-meters total length). Electrodes were not "juiced"
- ==F21 Chorro Creek Dog Leg pseudo3D== [ZIP file](https://cpslo-my.sharepoint.com/:u:/g/personal/jjasbins_calpoly_edu/EZWJRXr2rSdNsWNdquakibQBK7gkXRH7eV1D4IjxHBWFCQ?e=5f5T7Z). ZIP file containing field notes and four parallel 2D lines. One of the four lines is the same as the F21 2D ERT CCDL Reference Profile. EarthImager3D can combine these into a (pseudo)3D inversion. Electrodes were not "juiced".
