Finding oil with mr.greg
Goal: To practice being a geologist
Your group is a team of geologists from the consulting firm KGS (Kearny Geological Solutions) hired by BP to find likely oil reserves in the Gulf of Mexico. You will see simulated seismological data from that region, and your knowledge of how oil forms, to recommend a location for your client to drill.
Part One: You will be given a set of data taken by the KGS field team. They have conducted a seismic survey and processed the data to calculate the speed of sound in various layers of rock.
Your Job: Calculate the density of the rock at each grid point.
To do this, you need to know how to convert the speed of sound at that grid point to the density at that grid point.

Do The Following: Plot the speed of sound versus the density of these materials to find a linear fit. (A "linear fit" is a fancy way to say "draw a straight line through your data points".) Using your linear model (that line you just drew), find the density for the following sound speeds:
1) Plot what you know
2) Fit a line as close as possible to the data
3) Use your linear fit to find the relationship between other sound speeds and densities
