Claerbout in 4 parts

Correlation of waves -- amazing discovery in 1968, ignored for 30 years.

Earth seismic reflections: Amazing!

1st class -- 2-D reflection seismology

2nd class -- image estimation -- inverse problems of high dimensionality

One slide summarizes Chapter 8 here.

I’ll pull up this book and we’ll skim Chapter 8.

I hope I can bring up the graphics software that will take us through a “typical” reflection data cube(x,y,z).

You’ll be amazed!

Two million years, aboutin steps of 8000 years(a room full of Mississippi mud = 8000 years)A million years is a kilometer of mud, now stone.8000 years = 6ms two/way travel time.A land area of 5 miles x 5 miles.

We’ll skim thru this book (taught fall quarter).

This book I am working on now, teaching in fall quarter.
