Discussion Overview

The discussion revolves around the advancements in geophysical techniques, particularly seismic tomography, and how these advancements may aid geologists in understanding Earth's history through the visualization of subducted slabs. The scope includes technical explanations and references to recent geological meetings and research findings.

Discussion Character

  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants note that geologists are improving their ability to visualize subducted slabs, which may help in unraveling Earth's history over extensive time scales.
  • One participant references the 2012 Fall Meeting of the AGU, highlighting the progress in seismic tomography since the late 1990s, particularly the use of "noise" and other refinements.
  • Links to posters from the AGU meetings are shared, indicating the ongoing research and developments in the field.
  • There is a light-hearted acknowledgment of the thread title, with one participant attributing it to an article rather than original authorship.

Areas of Agreement / Disagreement

Participants generally agree on the advancements in seismic tomography and its implications for geological research, but there is no explicit consensus on specific outcomes or interpretations of these advancements.

Contextual Notes

The discussion does not delve into the specific methodologies of seismic tomography or the implications of the findings, leaving some assumptions and details unresolved.

The 2012 Fall Meeting of the AGU had a special session on seismic tomography. At that point it had come a long way from the stuff I was looking at in the late 1990's. Since 2012, with the ability to process and utilize "noise" and other refinements, seismic tomography has become an awesome tool. Here are a couple posters from the 2012 meeting:

I can't take credit for it, stole it from the article.
