Wow, I cant believe that I have less than two weeks left here! This summer went by very quickly; they usually do... The last several weeks have been the most productive of this summer. I have been working mostly in Matlab, writing scripts to filter out certain frequencies that I wish to ignore in my data, and plotting different time series graphs of several different EM recording sites from the years of 1989, and 1990. It took several weeks to obtain the desired data sets that I needed for proper analysis of the electromagnetic effects of the Loma Prieta event, but I finally have them, and now I actually am seeing some of the fruits of this summer's labor arising. Some of the graduate students here at Stanford are great... The past few weeks they have really helped me grasp a knowledge of signal processing and simplified the way I think about EM signals. The next week and a half will be the icing on the cake. I have done all the grunt work (i.e. writing scripts, understanding the data, collecting and converting data to a usable and comparable format, and reading numerous articles) and now am working on the payoff (making charts of data, doing cross correlations, etc). Overall this project has been a great learning experience for me. Stay posted for some thug hiphop lyrics that I will be writing about my summer later on this week...

So my advisor, Simon, is now back early, which is great news for me! We sat down and talked things out yesterday, and we will be meeting on a regular basis. Since the graduate student is not going to be able to help me anymore, I will be getting some help from two folks at the USGS in Menlo park, that have been working with Simon on this project for a while now. Today I will be doing research to try to find some of the raw geomagnetic data recorded by Tony Frasier-Smith from the 1989 Loma Prieta event. Once I have this, I will be comparing a years worth of that data to other stations (probably located in Fresno, and Boulder) data.

Hey folks! So I am finally back from traveling around, and also a week of field work in Nevada, and have computer access for the first time in a couple of weeks! My project this summer is still a little bit unknown, because my adviser, Simon, has told me that I can take any angle I want on the ongoing ULF EM project, and he has been gone for the past month! I am ready to meet with him on Monday, ask some questions and schedule a meeting with some people from whom I will hopefully get some help. As of right now, I am flying solo on this project, bc a graduate student who was supposed to be helping me dropped out :(
As far as goals for this summer go, I have several. First of all I would like to learn as much about geophysics as I possible can, and get a lot of useful experience. I want to become very familiar with the EM aspect of geophysics. I also want to branch out and make contacts in the field, which I have already done, both at Stanford and at the USGS. Another goal I am going to achieve is to make a sweet poster for AGU. I plan on using gluesticks, construction paper, and crayons. No seriously I want to have a very intriguing and professional poster at least brainstormed and begun by the end of this summer.
So far in my project I have been doing a lot of research, and reading publications that directly have to do with low frequency EM waves propagating in conjunction with certain seismic events. It is a very controversial topic, and for good reason, because the only recorded evidence, is from serendipitously recorded data on several different occasions. My project hopefully will be to compare some of this recorded data that shows a correlation with seismic events, to other EM stations that were recording at the same times, but in different locations. This might show that the increased signal power was only an increase in the magnetometer's gain.
Well thats all for now.

So this is my first blog entry, and I will provide the basics about who I am and what in particular I will be doing this summer.
First of all I am from Purdue University in Indiana, at which I study applied math, and earth and atmospheric science. I will be a senior this coming fall. I have chosen to work with Simon Klemperer at Stanford University, and I will be working with electromagnetic data, trying to correlate EM data with seismic events. I had already started this, and worked with some of the data for 2 weeks, and I believe it will be an interesting summer. I spent the past week, after orientation, in Yosemite, and the next two weeks I will be in Eureka, and Nevada doing some gravity field work with the USGS. After this I will be back to working with EM here at Stanford.
Technically I am on vacation right now, so I will post more when I get back from that!
