Tea Gardens to the Rescue
We switched to deploying our equipment for imaging faults and the structure beneath the surface to tea gardens to get away from power lines and buried the cables to protect them from gnawing foxes.

Dealing With Rain and Rats
As we continued our geophysical measurements, we had to deal with heavy rains, flooding fields, and rats and foxes biting our cables. Many cables were broken soon after sunset, ruining the measurements.

Fieldwork in Bangladesh During the End of Ramadan and Eid Festival
We have come to in Bangladesh in the pre-monsoon heat to better image the active faults beneath the surface using electromagnetic instruments. We are using the fallow fields from the just-harvested rice crop for our sites.
