July 13th, 2017

Halfway through the internship. I began the internship investigation filtering techniques used to separate up- from down-going waves (u d-gw). I was 'given' pre-processed data that was easy to work with and found some success separating these wavefields (primarily in matlab). Next, Whitney and I attempted to download/process new data. This processed has prooven to be quite challenging due to some disorganization of the DAQ. Additionaly, DAS data has more processing requirements than traditional seismic.

I think this is an extremely useful excersize. It was not easy, but it was not terribly hard either. This may be in part because it is a skill that I have practiced before. The hard part is to noil down a complicated project into a few sentances.

This type of excersize is useful in so many ways. First it is always a good thing to be able to explain your work clearly and concisely while networking within the field. It is also useful to explain what I am doing ALL summer to my family/friends who are interested in my life.

Lastly, I think it is helpful to myself to develope this short description so that I can keep the big gaols in site, and not get too bogged down in the details.

This was a skill that I knew I needed to work on, and I have begun to do so. I am testing using a digital notebook (power point) to keep a log of my work.
So Far I really think it is working well. Specifically, I like that I can easily put in figures from papers, or self generated. 
My weakness is still taking the time to actually fill in the notebook. I have a tendancy to get lost in my work, and forget about everything else. 
I have been forcing myself to add to it at least once a day, but could be doing even more tha that.

I am working with vertical seismic profile VSP data gathered using distributed acoustic sensing (oposed to traditional geophone data).

This data is collect via fiber optic cable's sensitivity to axial strain. The data was collected at an enhanced geothermal field in NV (Brady's natural lab.)
I believe this is reasonably close to reno... so if Brady is reading this you may know the area! Hopefully, this data will aid in monitering the water table in the geothermal field.
Thus far, the data has proven to be of poor quality. Much of the data was originally loss to do damage to the cable, but even the undamaged data is not the highest quality. 
Most of my work so far has been in processing the data to a point where an automatic picker can 'pick' first arricals of reflection wavefronts.
This data is raw in the sense of seismic, but it has been processed by EE working for silixa (one of the leading DAS companies) to put it into raw seismic form.
This is required because the actual measurments of the das cable is not partical accel, but rather strain.

I worked my first day at internship Wednesday (6/7). Dr. Trainor Guitton (Whitney) was very welcoming and I am excited to work with her for the summer. Her goals for me this summer will be different (somewhat) than what was originally thought.  For this reason, I will delay extensive analysis of my goals for this blog entry. Generally, I seek to further my marketable quantitative, and computational skills. Secondly, I hope to continue exploring the Denver area. This includes, developing professional relationships with people at the schools in the area (CU Boulder, CU Denver, and of course Mines). These schools have been on my radar for some time, and I relish the opportunity to spend some time in the area.

We just began internship orientation in Socorro NM (NM Tech). The first few days have been intelectually stimulating even though most of the topics covered so far are not new to me. However, I am a learner who needs to see (study) a topic multiple times before I feel comfortable with my knowledge. I really enjoyed our deployment of a seismometer on the first day. I am humbled and impressed by the eclectic skill of my fellow interns, and everyone has been great to meet. I look forward to continueing long lasting proffesional relationships with both fellow interns and instructors.
