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.

Deploying in the Mangrove Forest

We continued our electromagnetic expedition to image fresh and saline groundwater into the Sundarbans Mangrove Forest, the world’s largest. While guards protected us from tigers, it was a wild boar that dug up some of our equipment.
