GPR Dataset acquired in the GEO3 borehole of the Grimsel Rock Lab during a Salt Tracer Test on the 22nd of November 2017.

The dataset contains single-hole files.

GPR:
2 250MHz Malå Borehole antennas were used in the GEO3 borehole, with the Malå CU2 console.
The antenna separation in GEO1 was fixed at 1.76 m, Receiver on top, Transmitter at the bottom.
Reflection profiles were recorded while moving the antenna set from the GEO3 borehole bottom upwards.
A reflection trace was recorded every 10cm.

For each profile, the .rad file contains the acquisition parameters (ASCII file) 
and the .rd3 files are the Malå specific files with the raw data. 

The acquisition times and corresponding filenames are given in the GPR_Notes_20171122.txt file.

Salt Tracer:
Injection in INJ2 interval 4 (borehole depth: 22.89-23.89 m).
The injected tracer amount was 100 L with a conductivity of 60 mS/cm,
consisting of 99,98 kg water, and 4.04 kg of salt.
The injection lasted for about 50 min, from 11:09.
