Excursion to Dhaka
Finishing up in the muddy rivers of NE Bangladesh, we headed downstream to switch to the mighty Brahmaputra River system. However, on the way down I had to jump ship to go into traffic-clogged Dhaka for some meetings before rejoining her on the Padma, the name of the combined Ganges and Brahmaputra Rivers.

To Meghalaya and back
From our return to Jamalganj, we headed east searching for a river to carry us up to the Indian border across the Dauki Fault. Along the way, we celebrated Steve Goodbred’s birthday. However, even the biggest of the rivers proved too shallow for our boat. We switched to the

Return to Jamalganj
We have been sailing along collecting data, but so far the data quality is poor due to shallow gas in the sediments. We thought we might have some problems with gas, but the problem is more widespread than we expected. We are now out of the inland summer lake where we met the boat and…

Joining the Kokilmoni
After a great field season last winter, we had an extraordinary opportunity this fall, a research cruise on the Bangladeshi rivers collecting geophysical data. We are using the same technique that Lamont uses on its ship, the R/V Marcus Langseth, but a mini version. The basic idea is to use sound waves from bursts of…

Done in Khulna, back to Dhaka and then home
On Saturday, we finished up work at the site. Even at the last minute, it threw some challenges at us. We began the day with out reduced group eating breakfast down the street. We could no longer take the mediocre food at the hotel. Dhiman and Babu had been eating there for days. Besides paratha,…

Finishing up in Khulna
The last two days have been a little different as I spent much of them in Khulna rather than at the site. Since the Islam family does not have electricity, Hafizul would have to carry the expensive EDM (Electronic Distance Meter) and laptop back and forth to Khulna University to charge. However, we have an…

Finally getting it right
We are driving back to Khulna at 10:30 after our third excellent day in a row. However, there were still a lot of hiccups along the way. Yesterday, we were set to install the deep well, but when we arrived they were just starting to pull the pipe from the deep well. We had hoped…

Frustration and Progress, again
Days here seem to be coming in pairs. In the morning, we redid the 40m well, remeasuring, doing a dry run with no cement, mixing and putting in cement, lowering the fiber and everything went as planned. Then came the 60m well. It already had a history. It caved in twice when they pulled the…

At Bhandarkote, Khulna, the second site
Today we started working on the new site. Bhandarkote is a small village outside of Khulna, the third largest city in Bangladesh. The site is on a dirt road at the family home of a student from Khulna University. It a pretty remote rural place about 25 minutes off the main road through small country…
