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.

 LIST OF QUESTIONS, COMMENTS, AND HYPOTHESES FOR THIS BREAKOUT GROUP

 Processes:

  1.     Eruption and formation of lava flows;
  2.     Establishment and evolution of vent fields; thermal output;
  3.     Temporal variation and chemical evolution of each established vent; 
  4.     Changes in microbial populations and viral communities near seafloor;     
  5.     Distribution and changes in ecology of macro-faunal communities.

Approaches:

  1.     Best use of ships for long-term studies;
  2.     What can be done remotely?  Reasons pro and con for remote analysis?
  3.     Arrays of remote eco-genomic and volatile/nutrient analyses; 
  4.     Novel seafloor robotic laboratories - human in the loop? 
  5.     Remote sampling - transport to shore-based laboratories;
  6.     Mobile laboratories.

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?
