The main structure of this week was to familiarize myself with CERI, obtain a University username, and establish a CERI account for the computer labs. I was just able to accomplish the final task of obtaining my CERI account and was given a quick tutorial on how the Macs work. I spent most of this week studying what will be accomplished during my project and some of the methods of doing so. While I am still struggling with how a lot of processing works, I better understand the basics of seismic processing and what the information in a seismogram gives me. I also was able to better familiarize myself with Matlab and SAC. I met with Dr. Langston today, and we outlined the structure for my project into four sections. 1) correlate to get the source-receiver waveforms through cross-correlation and auto-correlation. 2) Dispersion measurements to find group and phase velocity. 3) Construct Tomography of the Norther ME. 4) Use Structural Inversion to get a map of the shear velocities at varying depths. Knowing these tangible goals, I am much more confident in my ability to perform each of them. I also was able to take a look what the programing will look like and what style of data I will be dealing with. The first goal of correlating and organizing the data from all of the stations should take roughly a month, but could be longer since a huge part of my project is locating the reflectors from autocorrelation. Dr. Langston discussed July 7th as being a rough goal for accomplishing this first part.
