I've officially returned from the field portion of my internship and am officially starting the figures portion. By figures, I mean starting to assemble my AGU poster, and trying to remember what I accomplished two months ago. Good thing I've been blogging regularly!
This past week of fieldwork was full of station installations, which meant less grunt work and more electronics work. There was still some hauling of sand and mulch around, not to mention the station batteries, but for the most part it was hooking up all the electronics and hoping that more of our sensors didn't break on us. I think we now have around 28 new stations online after the week, which is a solid achievement considering we were operating with only two-three install teams per day. A full station installation takes about two hours on average, and since our equipment wasn't completely organized, we typically installed two stations per team per day.
Some Highlights from the Week Include:
- Installing stations on day two in torrential rain. Can't have a full field work experience without some crappy weather right?!
- Learning tons of tips and tricks about the installation process
- Interacting with even more hilarious landowners.
- Closing out local restaurants four days running. Shout outs to the staff of Hunan Chinese Restaurant and Los Toribos Mexican Grill.
- Installing a station 100% by myself. I can officially say I have a station running that no one else helped with. Hopefully the data comes in alright....
Overall, it was another awesome week in the field. More stories and experience, more new information, and more new data for future OIINK researchers. Two weeks well spent. Sadly, I don't have any comical pictures for you all this week.
Now that we are back in the lab, it's AGU preparation time. Since abstracts are due on Tuesday night, I've been working all weekend to prepare mine. Since we haven't really had any time the past two weeks to work on them, these next four days are going to be really really busy. My model at this point is still pretty rough, but it's a first iteration model and will continue to be improved upon in the coming year. Because my model is in it's preliminary stages, all my results are considered preliminary as well. It's tough to capture the essence of my model in a single figure, as it is by nature a 3D figure. Here's a quick figure that communicates the gist of one of my results.
The red circles indicate the location of our array, as well as TA stations located in the range of the OIINK target area. The blue blobs represent areas of fast velocity anomalies, meaning that the first arrival of the P wave is faster than the standard travel times. This area is constrained to east-central Missouri extending west into the Illinois basin and to a depth of roughly 200 km. The velocities slow down as you travel into Kentucky. As I said before, this is still the first iteration model. It is missing both a crustal and basin correction, as well as more iterations. I also don't know if this is the ideal damping for the model, as I am still in the process of making the damping trade off curve. This might be something that I can get done for my AGU poster, but won't be needed for my abstract. Regardless, it's safe to say that the preliminary results indicate at least a general trend of fast velocities on the west side of the OIINK target area.
I'll post a better figure once I've straightened some things out. I've been crazy busy since returning back to the field. But hopefully this will suffice for now!
