Today marks my last official day at Indiana University. Josh and I will be heading this weekend to Purdue University, where we will spend the rest of our internships before heading out into the field in late July. This isn't quite the half way point of my summer, but it marks a good time for me to reflect on some of the things I've learned to date, and outline my goals for the next segment of my internship. While Bloomington has been an awesome town to explore, it will be fun to head out yet again to another new location.
Things I've Completed:
1. I can safely say I know my way around dbxcor and dbpick, the two tools I used for processing the raw data. I've now used these tools for a month and have improved drastically in my knowledge of the programs, how to filter and pick arrival times accurately, and why the tedious work is necessary. It feels good to be whizzing around the interface of a scientific program I'd never used before a month ago. Tasks that would have taken me 10 minutes at the start now takes less than a minute.
2. My shell scripting and GMT coding abilities have vastly improved. They aren't perfect and I still have a lot to learn, but the task of making a map or editing a shell/GMT script are no longer daunting. This is good, seeing as both these tools are used so often in the work I'm doing and will apply to work I'll being doing in the future, even for my classes at school. It is also nice to feel comfortable working in a terminal setting, as I'll be connecting to all my data remotely from Purdue for the rest of the summer.
3. I've learned how a tomography model is computed, and why it isn't always as easy as it looks. There is a whole lot of code behind the pretty maps, and I now have much more respect for the labor of love that goes into them.
4. I understand the context and larger scale of the problem I'm working on. After absorbing so much new information the first few weeks, I've finally grasped a sense of the larger problem that OIINK seeks to address. Between helping perform field work, working on my analysis, and seeing Josh's work, the problem has truly come alive.
Things Needing Completing:
1. The tomography model still doesn't work. We've spent countless hours adjusting geometry and parameters to no avail. I'm crossing my fingers that Dr. Pavlis and I can figure out the root of the problem next week. We took a look at the velocity models in a 3D visualization software today and have made some progress, but there are still some bizarre effects happening. Since my project relies on this model working, I'm anxious to have it start behaving correctly. In the mean time, I've been learning where we went wrong, which has really helped me grasp how tomographic models are constructed.
2. The 3D basin model I've talked about in some of my previous blogs still isn't constructed yet. Once this data is formatted into something useful for Josh and I, we will have to begin applying corrections to our data and make sense of the geometry of the Illinois basin. This may be something that we just begin to look at during our internship.
3. I need to starting thinking about and working on the details of my AGU presentation, poster, and abstract. Since we are heading out into the field during the end of July and early August, we have to get a jump on preparing some of this information. I am so excited to have the opportunity to share my work and want to take the time to represent myself and my work well.
That about sums up my time in IU and my goals for Purdue. You can wish me well as Josh and I move locations this weekend and that everything would go smoothly. I look forward to sending my next update from West Lafayette!
