Snapshot of AOOS data holdings

• Model data
• RAMS (23 Mb / day)
• Ice Concentration (58 Mb / day)
• Does not include subsequent processing space
• Relational database
• Over 6 million data points!
• Growth 300,000 to 500,000 points / month
• Does not include CTD or moorings!
• Access to research grade real-time data source
  that pushes worldwide data to AOOS at a rate of 2
  Gb / hour

25
18 Gb served this month!
Website Activity
26
IN Nearly 1 terabyte of data per month!
OUT Anticipate a large increase in outbound
traffic as we roll out the website and begin to
communicate with other regional ocean observing
systems and the national backbone.

Summary

• Development of data visualization and access
• Prince William Sound pilot project Local System
• Alaska Statewide
• Arctic Region
• Monumental challenges of data collection
• Maintaining interoperability
• Involved in the decision making process towards
  national implementation of ocean observation
  systems
• Local, regional and national level system of
  systems
• Standards metadata and archive
• Best practices and technology exchange

28
Next Steps for AOOS Data Management

• Standards
• Data transport INPUTS/OUTPUTS
• Overcome the challenges of data collection
• Allow for machine-to-machine interaction
• Continue with data aggregation
• Physics, biological, digital images, audio, video
• Develop additional products and applications
• Climate change detection
• Coastal and Arctic monitoring
• Education outreach
• Cross OOS and RA region product and application
  development
• Implement QA/QC and archive
• IOOS Archive Expert Team Steve Worley
  ltworley_at_ucar.edugt
• Metadata
• Superset based on the Federal Geographic Data
  Committee standard
• IOOS Metadata Expert Team Julie Bosch
