Life on a Tectonically Active Delta: Convergence of Earth Science and Geohazard Research in Bangladesh with Education and Capacity Building

Lead PI: Dr. Michael S. Steckler , Mr. Leonardo Seeber

Unit Affiliation: Marine and Polar Geophysics, Lamont-Doherty Earth Observatory (LDEO)

June 2010 - August 2018
Asia ; India ; Ganges-Brahmaputra-Meghna Delta
Project Type: Research

DESCRIPTION: The project will examine sediments and stratigraphic architecture of the Ganges-Brahmaputra-Meghna Delta as a record of fundamental fluvial and tectonic processes as well as the interactions between them. This will be done by drilling about 250 wells and using electrical resistivity profiles and marine multichannel seismic reflection along rivers and flooded areas to image subsurface features and correlate between wells.

OUTCOMES: So far two journal publications and two websites have been produced.

Back to the Sundarbans

As par of our trip studying land subsidence and elevation changes, we boarded a boat to travel through the Sundarbans, the world’s largest mangrove forest.

Servicing My GNSS (GPS) in Bangladesh Once Again

The sustainability of the Ganges-Brahmaputra Delta and Bangladesh depends on the balance of sea level rise, land subsidence and sedimentation. We are measuring the latter two across the coastal zone.

Land Subsidence in the Netherlands

At a symposium on land subsidence, I learned about how the Dutch transformed their country so that about a quarter of it is below sea level and how they cope with it.

Exploring the Sundarbans and Back to Dhaka

Our group of 24 Americans and Bangladeshis continued to explore the Sundarbans mangrove forest, rice farming in embanked low-lying islands, and heritage sites of Bangladesh.

Across the Ganges to Southwest Bangladesh and the Sundarbans

Our group of 23 American and Bangladeshi students and professors traveled from the Jamuna River to the Ganges and Gorai Rivers, and then down to an island on the edge of the Sundarbans, the world's largest mangrove forest.

Taking My Class to Bangladesh

My undergraduate Sustainable Development course is in Bangladesh for a Spring Break trip to see what they have been learning about. We will be touring the country by bus and boat to learn about the environment and people of Bangladesh.

Sylhet City, Geology, and Packing Up

We finished our electromagnetic survey and mini-field school in northern Sylhet, Bangladesh, with lectures and field trips to see the geology by car and boat.

Start of the Mini-Field School

We were joined in our electromagnetic investigation of the subsurface and earthquake hazard by a group of US and Bangladeshi students and professors for a mini-Field School.

Tea Gardens to the Rescue

We switched to deploying our equipment for imaging faults and the structure beneath the surface to tea gardens to get away from power lines and buried the cables to protect them from gnawing foxes.

Dealing With Rain and Rats

As we continued our geophysical measurements, we had to deal with heavy rains, flooding fields, and rats and foxes biting our cables. Many cables were broken soon after sunset, ruining the measurements.
