Seismic section

[dougoldenburg]

Can we organize the material differently so that it looks more like the magnetics section. This way each section would have a same "look and feel". I have made some suggestions at the end of the document

This is a major restructuring of the current material but it doesn't require a great deal of new content. Some of the missing elements in the current draft is the incorporation of the Applet and also a number of items in the present lecture slides.

An important matter that we should discuss is how to partition reflection, refraction, and MASW and yet keep the same manner of presentation. In the end, each shot generates refractions, reflections, and surface waves. The major difference between the surveys is then which of these signals is of most interest and which are regarded as noise. I've attempted to organize the material in a holistic sense that hopefully makes things simpler and more cohesive. However, the latter part of the outline deserves some thought.

Here are a few of my thoughts from my first-pass reading through the refactored seismic section. I have made them section by section.

I also have some thoughts on organization that I will create another comment for.

I look forward to hearing what you think @Pbellive , @thast , @dougoldenburg.

Introduction

• the "introduction" page does not need to be included (introductory material is already in the index page)

Elastic Properties

This section can be expanded. I would suggest

• a brief summary of the what is contained in "physical properties" along with a couple images (could be same as in physical properties section) to accompany the summary
• translation between different elastic properties (eg. wikipedia chart)

Basic Principles

Waves and Rays

• @dougoldenburg : do you know where these animations came from ? are they ours to use?
  

Reflection and transmission of plane waves

• There used to be a figure for this Reflection and Transmission of plane waves - I would suggest keeping this, or something like it in this section to help the explanation

Survey

Survey Design

• I would suggest renaming the heading "Survey Design" --> "Survey Types" or "Experiments". This is more a discussion on the types of seismic techniques rather than how to optimally design a survey (cc @dougoldenburg )

Data Processing and Interpretation

• I think we should aim to split these into 3 sections: 1. Data, 2. Processing, 3. Interpretation
• I would not highlight the "flat spot" interpretation - this is getting into attribute analysis and the provided wikipedia page is very sparse. In my experience, "flat spots" is not a commonly used term anymore in oil and gas.

@Pbellive @dccowan @lheagy I would suggest to use this image (in the repository) for the Reflection and transmission of plane waves

@Pbellive @dccowan @lheagy : Also, in the new version of the GPG, when in the subsection reflection/Physics or Data Processing , the toctree does not appear in the menu.
It make the navigation more difficult in my opinion, as a student looking for CMP (for example) would not see it appear in the toctree.

@thast , @Pbellive : can we close this?

[Pbellive]

I'd like to keep it open until the data section gets updated. That's fallen off my radar in the last 10 days but I'd like to get it done this semester.
