Welcome to the Second NSF Infrasound Workshop
Sign up sheet, Introductions, Lunch and Dinner!

• Workshop Aims
• Report on progress in fulfilling the goals of
  the First NSF Infrasound Workshop, and define new
  objectives for the coming years.
• Define possible areas of future cooperation with
  IRIS in the context of resource and data sharing.
• Present infrasound as a mature, proven
  technology suitable for deployment in remote
  areas.
• Identify future, ongoing, and past infrasound
  studies that demonstrate the added value of
  infrasound technology to basic research in the
  geosciences.
