Initial Outline/Likley Sources
Article Title: Inner Core Super-Rotation (New article)

Introduction:


 * Inner core specs
 * Basic description of compostion
 * Size
 * State
 * Rotation of the Earth
 * Rotation of the inner core with respect to the Earth
 * Mention that it affects geodynamo and cycling

Evidence for inner core super rotation


 * History of the discovery of inner core rotation
 * Unitl 15 years ago, it was not thought the inner core was rotating at a different speed
 * Geodynamo
 * Convection

Seismic velocity data support


 * Quantiative support
 * Eastern vs western velocity discrepancies
 * Why this suggests slower speed of rotation than before

Specific Facts


 * Specific speed
 * Unknowns in determining speed
 * Other facts that can be known through determing the speed

Current Scientific Conclusion


 * Slower than thought before
 * Could be large changes in speed
 * Could be more dynamic, in speed and structure
 * Must likely be rotating to keep current models previously mentioned (geodynamo and convection)

Article Selection and Comments
Article: Inner Core, adding information about inner core super rotation


 * Current information: three sentances about the inner core rotation
 * Very little cited material listed about it
 * Options
 * Add to/edit paragraphs (2)
 * New subsection (1) - enough information to do this I think
 * New Section (3)

Alternative Article: Earth's Rotation


 * Has no mention of inner core rotation
 * Would have to create a whole sub-section
 * Much more difficult and harder to tie together

Article evaluation

 * Looks good
 * Accurate
 * More depth? Other subsections?
 * Article is neurtral
 * Not biased
 * A few of the sources are questionable
 * Only a few people have written about the topic
 * Critical of the article
