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.

This summer I am in the Mississippi Delta in southern Louisiana helping to install an updated version of the compaction meters that we have in Bangladesh. The environment is quite different and we have arrived in the midst of an historic storm. Luckily for us the brunt of the storm is NW of us. So far, we are still able to work between the rain above and the mud below.
Heading out to our field area, we discovered that the abandoned river valley we planned to study was completely flooded. There was pani—the Bangla word for water—everywhere.
We arrived in Kolkata, and filmed by the Hooghly River. While it is no longer the main channel of the Ganges, it is still the Holy Ganges and we saw a funeral procession spreading ashes of a loved one while filming there. Then a 5 hour trip by car, ferry, rickshaw and boat to the Indian Sundarbans. The mangrove forest here is undergoing more erosion and land loss than in Bangladesh, where more river sediments can replenish it. The water here is more saline and the trees are small. A tiger was spotted by another boat, but was gone when we got there.
In the small town of Kolasib, we stayed in Hotel Cloud 9. I had been told since I was a child that I was always off on Cloud 9 and now I was actually here. However, the electricity wasn’t for the first few hours, so showers were cold, but the dinner was hot.
We finished our time in the Sundarbans with a silent boat ride in a tidal creek. The highlight was sets of fresh tiger footprints. We then had a long sail back to Dhaka with only one stop at a village. We then had a whirlwind tour of Old Dhaka with enough shopping to send the students back happy.
Leaving Hiron Point, we headed east through the Sundarbans to Kotka. At Kotka the students had walks through the forest seeing deer, wild boar and monkeys, while a smaller group also sampled near a set of 300 year old salt making kilns for OSL dating. We managed to finish while the tide inundated the site. We ended our day with a visit to an island that has recently emerged from the slain which the succession from bare sand to mangrove is visible.
After traveling by boat for two days, including crossing the Sundarban Mangrove Forest, we finally arrived in Khulna. We drove to the site of our compaction meter and separated into teams servicing the instruments, investigating agricultural practices, measuring arsenic in the well water and taking sediment samples for dating. We had finally started our work in rural Bangladesh.
Both of us are interested in the intersection of the environment and public health, and we wanted to explore a public health issue about which we felt ignorant. Water kept coming up in our conversations, because we felt that while water is a global issue, it often gets overlooked domestically among our peers. As such, we put together a six-week cross-country road trip, along which we are collecting stories about regional water issues.
