Continuing the Survey: Watermelon and Winds
Continuing our electromagnetic survey of fresh and saline groundwater, we saw the landscape change from lush watermelon fields to fallow rice fields as the salinity increased towards the sea.

Barisal and the Eastern Channel
We are continuing our measurements of fresh and saline groundwater in Bangladesh using electromagnetic instruments. We finished our first set of measurements and have now shifted farther east near Barisal where groundwater is fresher.

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.

Into the Sundarban Mangrove Forest and Back
For the last week of our trip, we traveled by boat to reach the sites where we are measuring subsidence in the Sundarban Mangrove Forest and nearby embanked islands.

From Barisal to Khulna
We continued to service our GNSS and RSET-MH equipment measuring land subsidence in coastal Bangladesh. Long distances, poor roads and slow ferries made for very long days, but we were able to complete the work at the sites.

Dhaka and Beyond
After a week of meetings and a wedding in Dhaka, we headed back to the field to service equipment measuring land subsidence in Bangladesh.

Back to Bangladesh at Last
I am finally back in Bangladesh after a pandemic hiatus. I need to repair precision GPSs that failed over the last few years. They are measuring tectonic movements for earthquake hazard and land subsidence, which exacerbates sea level rise.
