In the final push, we split into multiple teams, and caught up and completed all the seismometer installations on time.

Helping Jim’s team, I assisted in installing stations and scouting locations. While some stations go quickly, others took multiple trips to find a good site. Time is growing short for getting all the seismometer installations done on time.
As we finished scouting and installing the GPS stations, we started to assist the seismology team in getting permission to install there instruments in Tea Estates.
We drove through the hills of Sylhet passed rice fields and tea plantations, and through woods looking for appropriate spots to install our GPS systems.
Up ahead was a school, perfect for a GPS installation. Schools proved to be the best sites in the hills, which we covered in either tea plantations or woods.
From our base in Srimongal, now came the challenging work of finding appropriate locations to install the GPS. It requires a combination of the right tectonic setting and reinforced concrete buildings.
I am back in Bangladesh to start deployment of seismometers and GPS for a large new project that crosses 3 countries: Bangladesh, India and Myanmar.
The final phase of our revolves around visiting chars, sandy river islands, on the Ganges and Brahmaputra River. Chris and Dan are making measurements of soil salinity and moisture and spectra of the soil reflectance, while Liz and I collected samples for OSL dating and understanding the OSL properties of the river sediments here. This entails a mixture of driving around the country and spending time on small country boats and walking around the chars.
After helping Chris an Dan with soil salinity and reflectance measurement, Humayun, Liz and I moved onto the smaller M.B. Mewl to sail through the Sundarban Mangrove Forest to service our GPS station at Hiron Point.
Humayun, Liz and I headed to Khulna in SW Bangladesh a day after Chris and Dan. Along the way, we stopped at our sediment compaction meter for surveying and removing the GPS, and getting feasted by the family that hosts the system.
