More preparations: mini seismic experiments

To prepare for our big seismic experiment, we have collected a couple of miniature seismic datasets.  The shallow geology varies substantially along our profile and is very important for planning the depth of drilling and size of our seismic sources. In particular, we need to determine the depth to a limestone layer in a few places.   The same seismic method that we will use to understand the deep geological structures beneath Georgia can also be used at a smaller scale to examine layering in the upper ~100 ft (~30 m) beneath the surface. We recorded the data on 24 geophones attached to a 230-ft-long (70-m-long) cable.  The source was a modified shot gun that looks like a pogo stick.  We drilled small holes in the ground, loaded the gun and stuck it in the hole. To limit the kickback, we weighted the gun down with a metal plate topped by two heavy jugs filled with sand. Hit the plate with a mallet and – BANG – a seismic source! Not a bad way to spend a sunny Sunday!

Bricks, an Archeological Site and Home

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. We walked past the rows of drying unfired bricks to the massive kiln built from the bricks themselves. We saw them feeding coal into the hot, actively firing part and unloading bricks from the completed quadrant. This would be followed by loading of raw bricks for the 12-hour firing. This factory makes around 9,000,000 bricks in the six-month season. Although it was their lunch break, they demonstrated the mixing of the mud with a little sand and let me carry a half-full wheelbarrow load to where the bricks were

shaped. I spilled a full load when I tried to move it. The experienced brickmakers took about 30-seconds per brick.

We stopped for lunch at the same roadside restaurant, then went to find Wari-Betashwar. Getting to the archeological site was not easy, but a mixture of my hand-held GPS with a Landsat image and a Bangladeshi phone with completely inaccurate Google maps eventually got us there a little after 4 p.m. We toured the site with the chief archeologist, but all the excavations had been filled in to protect them during the off-season. As we walked around the 600m by 600m protective wall, Prof. Rahman explained the history of the site. This urban

center was founded around 500 BC on land slightly uplifted by one of the anticlines. The slight extra elevation protected the land from flooding. The site was by the side of an old path of the Brahmaputra River and was thus a major trading center. Artifacts from as far as Greece and Rome were found here. After a gap in the record, the city flourished again in the 7th century AD, before being abandoned. The rise and fall of the center may be tied to avulsions, or switches in position of the Brahmaputra, making the site an interesting confluence of tectonics, rivers and people.

Continuing on, the students got a taste of Dhaka traffic as we approached our hotel near the airport. Now came the real

splitting up of the group. The foreigners would stay overnight to begin our return home, while the Bangladeshis would fight the traffic to return to Dhaka University and their homes. Many of us spent most of the time until our 2:30 a.m. departure talking.  Twenty-three of us and our luggage and equipment managed to squeeze into a 21-seat bus and made it to the airport. Now, once again problems with our tickets arose. While most of us were fine, almost half only got boarding passes as far as Abu Dhabi, or none at all. Eventually they fixed the problem for most of them, and all of us were able to board the delayed aircraft. The delays here and in the flight to New York and Chicago will mean that the vast majority will miss connections.  At least my nightmare scenario of missed flights and connections was happening on the way back. Not the smoothest ending, but it has been a great trip and a very successful field school. Several of the students are trying to figure out how to get back to Bangladesh, and a lot of lasting friendships and connections have been made.

Field School: Sylhet Tectonics

The drive from Tangail to Sylhet turned out to be grueling. We took a longer route that skirted Dhaka to avoid the traffic jams that people hit earlier in the week. Unfortunately, with the slower buses that route took 13 hours. We didn’t hit our lunch stop until 4:30 p.m., where Badrul and Ashraf had been waiting to join us for five hours.  It was dark by the time we drove past the first anticlines, and we didn’t get to the resort until 11 p.m.  We picked our roommates, got our rooms and had a very late dinner. 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.

The new resort where we were staying was tucked away in a corner of Bangladesh along the Shari River about a kilometer from the Indian border. With a cold pool and only slightly warmer not-hot tub, views of the woods and hills, this is by far the nicest place I’ve stayed in Bangladesh. Given the late arrival, we delayed the start of the classroom day by an hour.  The classroom was in a separate building closer to the river The first classroom day covered the stratigraphy and structure of the sediments and rocks we would see the next day. With lots of questions, the day ran late.

We started early and argued over an outcrop on the driveway of the resort. We continued down to the Shari River, where I had previously visited the geology by boat. Numerous

country boats were mining and transporting sand from the river. We worked along the shore, climbing over and visiting outcrops.  The beds dipped steeply into the ground, folded by the tectonics, but also provided evidence that a large braided river used to flow here. One possibility is that it was the Brahmaputra from a time before the uplift of the 2 km-high Shillong block pushed it 200 miles to the west. Eventually, we could not go farther along the river. We took an inland path farther north, but when we rejoined the shore, we were blocked again. A short time later, after a conversation with the Bangladeshi border guards stationed here, they flagged us a passing boat. It ferried us across the river, but not before

several on our party practiced their cliff jumping technique.

After spending some time on an outcrop where we were filmed last year, we took an inland path. Along the way we met Johnny the elephant, and a few groups of students got elephant rides. We continued past tea gardens and rice paddies and finally emerged to a large outcrop of shallow marine sediments along the river. At this earlier time, the coastline was north of us, and the delta was prograding to the south as a result of all the sediments eroding from the Himalayas. The younger river sediments we had seen earlier had been deposited after the coast had pushed past here. We stopped for lunch, looking across the river at the India-Bangladesh border and a pile of watermelons waiting for a

boat to take them downstream. Two students swam across and purchased two for dessert. Then Badrul flagged down a large boat to taxi us downstream back to where we started.

After a few geology stops along the way, we reached Jaflong.  At this site, there is a mixture of mining of sands and gravels from the river, and tourists looking to view the massive Shillong uplift in India. We stopped at an overlook near our GPS and seismology stations. Then a group of us descended to some outcrops and the chance to join the tourists at the international border. The river had shifted a little since I last was here, and now the best viewing site was officially in India. The Indian and Bangladeshi border guard let us and everyone else cross the

border to the little spit of land for a better view. Many photos later, we walked back to the buses and returned to the resort. Dinner was delayed and about half of us took the opportunity for a dip in the freezing pool to rinse off the sweat and grime.

Our final classroom day conversation included multiple aspects of the interaction of the rivers and the tectonics that our project focuses on. We ended with several students presenting their research from places across the globe. The last item was a group photo close to the Shari River. The last field day took us farther southwest to Sylhet City itself. The Cricket Stadium is surrounded by outcrops that we walked around, passing a pet monkey as well.  After lunch at the stadium and a peek inside, we had to make a decision. There was not enough time for

both the outcrops at the airport and shopping in Sylhet. The group split, and each bus went to one of the sites. I chose the outcrop. The river sediments at the airport were clearly different from the stadium and showed that the sediments were deposited while the 80m-high Sylhet anticline was growing.  They were muddier where the anticline was tilting the land northwards, and sandier with gravels on the other side of the anticline where the southward tilting had steepened the river.  We headed back, stopping to at least buy some tea from the region. However, we got back too late to hold the bus vs. bus cricket match. Just some practice would have to do, until the BBQ that evening.

Laying the groundwork

Sugar - Wed, 03/05/2014 - 22:56

We have just arrived in sunny Americus, GA from the cold north to ramp up for the SUGAR project. The peaceful, pastoral landscapes of southern Georgia mask geological structures created by a series of dramatic events that were central to the formation of the North American continent.  During SUGAR, we will use sound waves to image these geological structures.   Less than 2 weeks from now, we’ll deploy 1200 small seismographs along a 200-mile-long line that extends from north of Columbus to south of Valdosta with the help of a cadre of students from across Georgia and beyond. These instruments will record sound waves generated by a series of controlled blasts in deep drill holes.
Spanish moss lined trees along our transect south of ValdostaCollecting these data will involve a week of intense work by >30 people. However, just laying the groundwork for this effort has already required a long list of (sometimes novel) tasks.  When we conceived of this project, we drew a couple of straight lines on a map that would enable us to capture the geological features that we wish to study: the South Georgia Basin, the Suwanne Suture, and frozen magmas from the huge Central Atlantic Magmatic Province.  In reality, we must create this line by knitting together a patchwork of roads.  During a couple of planning trips, we bumped along on dirt roads, cruised county lanes, and zoomed down state highways mapping out the best route. 
Dan and Steve scouting our route. Our seismometers will line county and state roads across southwestern Georgia, and both seismometers and seismic sources will cross private properties. Identifying private landowners to request permission has transformed us into detectives. In most cases, the name and address of the owner are easily found on the tax assessor's website for each county.  But actually getting in touch with people is not so easy! We mailed letters. We put flyers directly into people’s mailboxes. We searched for phone numbers online and left messages (sometimes multiple messages…). We found websites and email addresses for companies, and sometimes wrote to people about our project through website forms (including those for a bank, a dentist's office and a website selling organic beef!).  Happily, once we made contact, individuals and companies have been very welcoming and graciously granted us permission – southern hospitality in action!  A litany of other preparations have already been completed or are currently underway. Drilling of the holes for seismic sources has just begun, and the seismometers will arrive very soon. We are definitely ready for the transition from preparing to doing....

Field School: The Brahmaputra River

Geohazards in Bangladesh - Mon, 03/03/2014 - 23:29
With our students all finally arrived, we started the classroom component to provide the background on the geology of Bangladesh.

With our students all finally arrived, we started the classroom component to provide the background on the geology of Bangladesh.

It has been an incredibly busy week. We have had between 42 and 48 people here for the field school, including 35 students and 12 instructors (seven to 10 at a time). 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.

After a good night’s sleep we started on the first classroom day. Our full five days near the Brahmaputra River would focus on the river processes and the stratigraphy they produce. We stopped the lectures at 4 and all piled into the bus

to see the embankment built to protect the city of Sirajganj from the westward migrating river. As is often the case in the dry season, they were repairing the embankments from last summer’s collapses. We rented two country boats and sailed along the embankment and walked back to the buses on the top of it. It is an impressive structure, but in need of continual repair to keep up with the river.

The next two days were spent on the river and its mobile islands, called chars. Setting up the equipment for the river surveying was hampered by a lack of power for drilling holes. A Bangladeshi drill and bow solved the problem, but not before rearranging the schedule. On the first day we all visited the char near the 5 km

Bangabandu Bridge over the river. We spent the day viewing sedimentary structures and seeing the villages on this island that is almost entirely underwater during the monsoon. For the second day, we had to split the group. One contingent joined Jim Best as we surveyed the river with an ADCP, which measures water velocities from the top to the bottom of the river, and a sidescan that provides images of the bottom on either side of the boat using sound. The other, yielding to student requests, went to Tangail, the nearest city, for shopping. When everyone returned, we held a cricket match, with most Americans learning the rules on the fly. We finished the five overs per side as darkness fell.

We went back to the classroom the next day for more lectures on remote sensing of changes on the delta, stratigraphy,

subsidence and arsenic contamination. The hands-on experience was analysis of two sets of well samples that had been drilled the days before. Everyone had a chance to describe the samples, measure magnetic susceptibility and use a portable XRF machine to measure chemistry. We have found that magnetic susceptibility and strontium content are a good way to characterize whether sediments have come from the Brahmaputra River or not.

Finally, our last field day here was doing a resistivity imaging survey over the two bore holes and across the boundary between the Brahmaputra floodplain and the upland strata of the Madhupur tract. Generations have debated whether the transition is a fault contact or not. We would collect some data to try to answer the question. The students also got

to visit another tube well being drilled. Tube wells, drilled primarily for drinking water, is a local drilling method whereby a team of a handful of people can drill a 100m well in a day by hand. After everyone helped set up the 750m long resistivity line, most of the American students went to see the tube well drilling. The Bangladeshis, who have all seen tube well drilling, stayed with me to help run the resistivity line. As it turns out, Liz Chamberlain was pulled into a local villager’s home to have her hands tattooed with henna by a woman and her daughters. She missed the tube well drilling, but gained an exciting personal experience. It was also the first time the students were in a Bangladeshi village. We were the center of attention and many photos were snapped by both sides. We gathered up the resistivity equipment and then had informal student

Upon our little spinning rock,
Cosmic rays and debris knock.
Through great fields and waves we race,
Not empty, our broad path through space!
We’re touched, long fingers from afar:
Energy from our bright star.
A fusing, roiling dynamo,
Magnetic fields induced by flow.
Eleven circuits round our wheel,
Her heartbeat’s pulses we can feel.
In search of answers, models run,
Probing rhythms of the sun.

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, the future Bangladesh, from Pakistan. It is a time of plays, book fairs and poetry reading celebrating the Bengali/Bangla language. There are also laying of flower wreaths at the Shahid Minar, the monument where the killings occurred near Dhaka University, and many smaller copies throughout the country.

party left the Bawali in two vans, stopped to pickup equipment, and settled in for a long uneventful drive, or as uneventful as driving in Bangladesh can be.

The next day my group went to Mawlana Bhashani Science and Technology University to try to install a new GPS. After various meetings and cups of tea, we explored the rooftops looking for the perfect site for the antenna. Unfortunately, the building we were in was not quite finished. It was a good site, except the columns on the roof were still a mass of rebar and the concrete was yet to be poured. More meetings, coffee, sweet desserts, and we checked out other roofs. Many buildings at the relatively new university are unfinished. The older finished ones are lower and the clear view of the sky we need is blocked by trees. The
