The last day! Today we took the pneumatic sound device apart to remove some spacers that would double the energy release from the device. Exciting more energy into the subsurface may allow us to see deeper features. We are only doing this to get a feel for the device and what the results may be, but doing so is not part of the overall project. While monitoring the increased energy, Xenia processed the final dataset from yesterday.

After an hour of testing, the sound device was pulled in as well as the streamer. We would continue down river the remainder of the day using the Chirp. The streamer and pneumatic sound device were dismantled and stored.

The day was bitter/sweet. We had a wonderful time conducting the research. The research team and Corps of Engineers employees melded well. The data we collected looked great and further processing should reveal much about the New Madrid Seismic Zone. However, we had also been on the river for quite some time pulling long days. So it is time to go home and be with friends and family.

Thanks for following this blog. We’ll be back on the river again next year.
