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
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.
