Summary

• Data dissemination SEED format for archiving
  at IRIS. Metadata can be difficult to
  standardize.
• Capability for real-time data streaming.Quality
  control is responsibility of the operator.
• Sensor availability Possibilities through
  PASSCAL, IRIS Consensus, Geoinfrastructure, MRI.
• International collaborative effort define
  project. Continental dynamics.
• Large-scale arrays, 100s of instruments.
• Large ATM project, coordinate with NCAR.
• Export controls on some specialized software.
  PMCC available for academic use. Matseis
  available.
• GEOSS, products for society benefit.

3

• Domestic (US) involvement in GEOSS.
• Infrasound as reliable technology.
• Applications in civil defense (HS), natural
  hazards.
• IMS data available from US, Canada, and Germany,
  soon UK. Two-day latency. Possibility for
  streaming.
• More extensive use of IRIS microbarograph data.
  Sampled at 0.5 or 1 Hz.
• Use of hydrophone data.
• Multiple technology data for case studies.
• Need better links to ATM and OCE programs.
• Possible workshop on Atmospheric Tomography.
• COV workshop in volcano-acoustic monitoring
  (01/06).
• Produce workshop report.
