Please make use of the comment space below    to add any additional questions or materials you want participants in the Breakout Session to be aware of prior to the session on Tuesday April 21.

Processes:

  1.    Magma chamber geometry and inflation; 
  2.     Deformation and changes in brittle-ductile zone; 
  3.     Magmatic heat and volatile output to overlying, adjacent hydrothermal system;   
  4.     Fracturing of crust above magma chamber; 
  5.     Phase separation and heat transfer mechanisms

Approaches:

  1.     Measurement of deformation and of heat transfer;
  2.     Expansion of seismic and geodetic sensor footprints; 
  3.     Repeated multichannel seismic “snapshots” of subsurface structure; 
  4.     Improve computational resolution for seismic data reduction;
  5.     Gravity surveys.

Key Discussion Themes to be Addressed:

  1.   What are the priority science questions? (Review provided list; add new ones if needed)
  2.   Near-term: What science questions can be addressed with resources now available? 
  3.   What measurements can characterize sub-systems before, during and after eruptions?
  4.   What time and space measurement scales are needed to address science questions? 
  5.   What can be measured using in situ sensors or shipboard measurements?  
  6.   What could be measured with additional approaches?
  7.   Transformative? Check NSF Web site for definition
  8.   Intermediate term: What additions could better address priority science questions?
