Indian Sundarban

Overhanging rooks and slumps reveal the much larger amount of erosion and land loss in the Indian Sundarban

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.

Mapping Faults Hidden below Lake Malawi

Marine seismic studies like ours are routinely done in the oceans using scientific equipment and research vessels outfitted specially for these purposes. Collecting comparable data in a great lake in Africa requires creative repurposing of available vessels and adaption of scientific equipment.

This week marks the launch of the new Columbia Initiative on Extreme Weather and Climate, a cross-disciplinary collaboration between a variety of centers, research groups and individuals from across Columbia University. The Initiative, led by Adam Sobel, kicked off on Monday evening with a World Leaders Forum panel event in Low Library. Panelists discussed a wide range of science and policy topics related to extreme weather, showing the interdisciplinary nature of the new Initiative.

SeismoDome

Lamont-Doherty Earth Observatory scientist Ben Holtzman grew up discovering science through interactive exhibits in San Francisco’s Exploratorium and now provides a similar experience for others. Holtzman designs immersive shows that allow people to experience what earthquakes and seismic waves look and sound like as they move through and around the Earth. On Monday, November 17th at the American Museum of Natural History Hayden Planetarium, Holtzman and his collaborators will present one of these shows, the second installment of SeismoDome: Sights and Sounds of Global Seismology.

Hydraulic fracturing, or fracking, the controversial method for extracting natural gas, has become a hot button issue across the U.S. But let’s try to look objectively at its benefits and risks.

Bricks, an Archeological Site and Home

One of the myriad brick factories in Bangladesh.  The lack of rocks means bricks are widely used for construction.

It was time to pack up and leave. Shofiq, who is from Sylhet, was dropped off near his home and the fellowship of the rocks was broken. We settled in for another long drive. We made an impromptu stop at one of the numerous brick factories scattered across Bangladesh. Here, the workers immediately started snapping pictures of us with their phones.

Field School: Sylhet Tectonics

Most field trips have a “death march” hiking a long way through forest, swamps, hills or deserts to get to a remote outcrop. We have a “death bus ride” instead.

Field School: The Brahmaputra River

Sunset over the  Brahmaputra River as we prepare to depart the region for NE Bangladesh.

The first day was very light for the jet-lagged students, just a short introduction to the field school and some background, and then introductions all around as we started to get to know each other. The final group of nine students finally arrived around 9 p.m. They were the most worn-out, bedraggled bunch of travelers I have ever seen.

Tangail and the Start of the Field School

The Shahid Minar in Dhaka, the monument to language day on the site of the killings.  There are many smaller copies around Bangladesh.  On Language Day, they are covered by wreaths of flowers placed by everyone from politicians to school children.

Feb. 21 is Language Day in Bangladesh. It is a holiday, now adopted by the UN as International Mother Language Day. It commemorates a day in 1952 when a crowd of Bengali students protesting Pakistan’s adoption of “Urdu and only Urdu as the official language of Pakistan” were fired upon by the police. It marks the beginning of the move towards the independence of East Pakistan.
