It is a love hate relationship since reciprocity checks tend be a good guide for data consistency.īelow is a map of the study area generated in Matlab. Some would look horrible but some would look like the one pictured above. Generating decent reciprocity checks was the most challenging and most satisfying. This generates a slight offset with arrival times because they are not evenly spaced. It also creates an offset at certain areas because the seismic line I am using is an arbitrary line across the grid. It has nearly reached a point of acceptance that it will not be perfect. However, this is science and the world is not uniform. At first it was terrifying because they were all over the place! As time when on, they became more refined but still nowhere near where I’d like. I began running reciprocity checks on my own first arrival picks. Many of the technical jargon must be removed, not only for them to understand you, but to not come off as pretentious. In everyday conversation with people that lack an earth science background, the speech would be simplified. In an interview, you could most likely be more technical. Most likely there would be multiple elevator speeches based on people's backgrounds.

One must also consider the type of audience in developing this speech. Overall it was easy because I guess thinking about our difference in our projects helped in developing a better understanding of the project as a whole. The biggest difficulty was to have a distinct difference in the speeches of Kat and mine. The challenge is welcomed!Īs for the assignment this week, in regard to the elevator speech, it was not too difficult. Well, they are and it takes a completely different approach to processing and interpreting. The techniques for refraction and reflection would not seem to be so different. So, the data is not deep and one may assume it to be uncomplicated, however, it is foreign to me since I have only dealt with deep seismic reflection data. All of this will result in a comprehensive understanding of this specific CZO to the depths of around 50 meters. Also, since I have past experience in well log analysis, I will be implementing that into my data as well. I continue to do much of the same things that I was before, but this time on my own seismic lines. Now I have my own set of data to work on. Up until the third week, Kat and I had been working on the same data. The reason I waited and lumped these three weeks together is that I was told the coming weeks would be much of the same work. Eventually all of this will lead to interpretability and understanding the subsurface structure. Initially, I will pick first arrivals on refraction lines and develop a velocity model. I will be tasked with processing and analyzing the dataset. This project will consist of 4200 geophones and 62 3 component nodes over a 300 x 300 m2 area. Despite extensive research into the CZ, fundamental questions remain regarding how the CZ forms, how the CZ evolves, and how the CZ will change in the future. Recent advances in standard geophysics methods and instrumentation now allow us to probe the CZ at previously inaccessible scales and depths.

For many decades investigating the deep CZ (> 5 m) where the important regolith/bedrock boundary sits and where water reservoirs reside was largely inaccessible owing to the time and cost of drilling/hand augering. The critical zone (CZ) represents the outermost layer of the Earth where interactions between the atmosphere, soil, bedrock, and organisms regulate the formation of life sustaining
